RESUMEN

OBJECTIVE: Shone's complex comprises of a combination of congenital cardiac anomalies causing obstructions in the left ventricle's inflow and outflow tracts. This systematic review aims to evaluate the clinical features and surgical outcomes of Shone's complex. METHODS: An electronic literature search of PubMed and Scopus was performed to identify relevant studies related to the presentation, management, and outcomes of Shone's complex. Two reviewers independently performed selection. Data on study characteristics, participant demographics, interventions, outcomes, and follow-up durations were extracted and analyzed. RESULTS: A total of 691 papers were identified, with 18 studies included in the final analysis. The majority of the studies (n = 12) focused on the pediatric age group. The most common clinical presentations were coarctation of the aorta (n = 17) and mitral stenosis (n = 12). Surgical interventions often involved staged approaches, prioritizing outflow before inflow obstructions. Mitral valve repair was preferred over replacement due to better long-term outcomes (n = 8). Biventricular repair was recommended due to improved postoperative outcomes, but often needed reoperations. Reoperations were common, primarily due to recurrent coarctation (n = 10), subaortic stenosis (n = 8), and mitral valve dysfunction (n = 7). Pulmonary hypertension (n = 10) and arrhythmias (n = 11) were significant complications. Most patients were in modified Ross/NYHA functional class 1 on follow-up. Mortality rates ranged from 4 to 28%, with better outcomes associated with early and strategic surgical interventions. CONCLUSION: Early diagnosis and biventricular repair were associated with better outcomes while transplantation was often an eventuality. Standardized diagnostic criteria, long-term follow-up, and consensus guidelines are needed to improve the management of this congenital heart disease.

RESUMEN

The coarctation of the aorta (CoA) combined with heart defects or cerebral artery aneurysms is more prevalent in clinical practice. However, cases of concurrent bilateral iliac artery dissection (IAD) are extremely rare and have not been reported. Here, we described a case with CoA combined with bilateral IAD. The patient, a 62-year-old male, presented with acute intermittent claudication accompanied by pain and aching in both lower limbs after walking. Following a thorough medical history inquiry and examination, the patient was diagnosed with acute bilateral IAD combined with CoA. The patient underwent endovascular treatment. Postoperatively, the aortic diameter recovered, and the bilateral IAD disappeared, yielding satisfactory therapeutic results. Conclusively, endovascular treatment of aortic coarctation combined with IAD is an effective therapeutic approach, enhancing patient survival and improving their quality of life.

RESUMEN

BACKGROUND: Extra-anatomic ascending-to-descending aortic bypass grafts have historically been utilized as a safe and effective solution for repairs of complex coarctation of the aorta. However, reports on reoperation in these patients remain rare. We present a case of an aortic valve replacement and coronary artery bypass grafting in a patient with an extra-anatomic ascending-to-descending aortic bypass graft. CASE PRESENTATION: The patient is a 59-year-old male with a complex aortic history, including repair of aortic coarctation with an ascending-to-descending aortic bypass graft 13 years prior, was admitted to the hospital for shortness of breath and chest pain that had developed over the past year. On further workup, he was found to have severe bileaflet aortic valve stenosis, non-ST elevation myocardial infarction, and moderate coronary artery disease. He underwent surgical aortic valve replacement and coronary artery bypass grafting. Given his unique anatomy, cardiopulmonary bypass approach involved separate cannulation of the right axillary and left common femoral arteries with cross-clamp of both the aorta and the extra-anatomic graft. Using this approach, the redo operation was successfully performed. CONCLUSIONS: Reports on reoperation after ascending-to-descending aortic bypass grafting are rare. We describe our approach to cardiopulmonary bypass and reoperation in a patient with an extra-anatomic ascending-to-descending aortic bypass graft.

RESUMEN

BACKGROUND: Although coarctation of the aorta without concomitant intracardiac pathology is relatively common, there is lack of guidance regarding aspects of its management in neonates and infants. METHODS: A panel of experienced congenital cardiac surgeons, cardiologists, and intensivists was created, and key questions related to the management of isolated coarctation in neonates and infants were formed using the PICO (Patients/Population, Intervention, Comparison/Control, Outcome) Framework. A literature search was then performed for each question. Practice guidelines were developed with classification of recommendation and level of evidence using a modified Delphi method. RESULTS: For neonates and infants with isolated coarctation, surgery is indicated in the absence of obvious surgical contraindications. For patients with risk factors for surgery, medical management before intervention is reasonable. For those stable off prostaglandin E1, the threshold for intervention remains unclear. Thoracotomy is indicated when arch hypoplasia is not present. Sternotomy is preferable when arch hypoplasia is present that cannot be adequately addressed through a thoracotomy. Sternotomy may also be considered in the presence of a bovine aortic arch. Antegrade cerebral perfusion may be reasonable when the repair is performed through a sternotomy. Extended end-to-end, arch advancement, and patch augmentation are all reasonable techniques. CONCLUSIONS: Surgery remains the standard of care for the management of isolated coarctation in neonates and infants. Depending on degree and location, arch hypoplasia may require a sternotomy approach as opposed to a thoracotomy approach. Significant opportunities remain to better delineate management in these patients.

RESUMEN

BACKGROUND: This study's objective is to describe outcomes of adult patients who underwent thoracic stent graft placement treatment for primary or recurrent aortic coarctation. METHODS: This is a retrospective study of 30 adult patients who underwent thoracic stent graft placement for aortic coarctation at our institution. Average age was 46.5 years, with 53.3% of patients presented with no prior treatment or repair for coarctation. Indications for repair included gradient ≥20 mm Hg with anatomic evidence of coarctation on imaging with left ventricular hypertrophy, pseudoaneurysm, aneurysm, refractory hypertension, or claudication. Stent grafts used for repair included MDT (Medtronic, Santa Rosa, CA) and GORE TAG (W. L. Gore & Associates, Flagstaff, AZ). RESULTS: Patients were observed for a median of 979 days, with one death during the study. All patients had complete resolution of symptoms with no recurrences. Thoracic endovascular aortic repair significantly reduced the gradient across the coarctation (P < 0.0001). Aortic coarctation diameter significantly increased at 30 days postoperatively and continued to increase up to 5 years posttreatment. At 3+ years, aortic remodeling was observed at the coarctation site and surrounding regions. At 30 days, systolic, diastolic, and mean arterial pressure were all reduced. Systolic and diastolic blood pressure and mean arterial pressure continued to significantly improve 1-year posttreatment. CONCLUSIONS: Stent grafts are a safe and effective treatment for aortic coarctation. We observed a clinically significant improvement in blood pressure and longitudinal aortic remodeling of the coarctation segment and the entire aorta that persisted more than more than 3 years.

RESUMEN

OBJECTIVE: This study sought to elucidate clinical and imaging findings predictive for malperfusion syndrome after blunt thoracic aortic injury (BTAI). BACKGROUND: There is limited literature on malperfusion syndrome after BTAI, and the timing of thoracic endovascular aortic repair (TEVAR) in patients with this condition has not been defined. METHODS: A retrospective analysis of prospectively collected data of patients with BTAI treated between January 2021 and October 2023. Clinical and thoracic aortic (TA) imaging data, time to TEVAR, in-hospital death, and malperfusion/reperfusion sequelae (paraplegia, renal/visceral/limb ischemia, and compartment syndromes) were assessed. Correlations between clinical and imaging findings, time to TEVAR, and outcomes were evaluated. RESULTS: Of the 19,203 trauma patients evaluated, 13,717 (71%) had blunt injuries and 77 (0.6%) had BTAI. The majority (67.5%) were male, with a median age of 40 years (IQR: 33-55). TEVAR was performed in 42 (54.5%) patients. Seven (9.1%) patients presented with clinical and TA imaging criteria for traumatic thoracic aortic coarctation (TTAC), including diminished/absent femoral pulses and TA luminal narrowing of 50% to 99%. The median time to TEVAR was 9 (IQR: 5-32), 11, and 4 hours for all non-TTAC and TTAC BTAI patients, respectively ( P =0.037). Only TTAC patients presented/developed malperfusion/reperfusion sequelae. In-hospital mortality rates were 7.8%, 5.8%, and 29% for all non-TTAC and TTAC BTAI patients, respectively ( P =0.09). Aortic-related mortality occurred in only 2 (2.6%) TTAC patients. CONCLUSIONS: Patients with clinical and TA imaging manifestations of TTAC are predisposed to malperfusion/reperfusion sequelae if TEVAR is delayed. We recommend the emergent repair of all BTAIs with TTAC.

RESUMEN

BACKGROUND: The purpose of this study was to review echocardiography-based diagnosis of persistent fifth aortic arch (PFAA) in children. METHODS: From January 2015 to December 2022, we retrospectively analyzed the echocardiographic findings and the relevant clinical data during follow-up of patients with PFAA who were treated in the Third Affiliated Hospital of Zhengzhou University. The diagnosis was confirmed by computed tomography angiography or surgery. RESULTS: Seven PFAA cases included two Weinberg type A and five Weinberg type B. The anatomical details of PFAA were assessed using a combination of the long-axis view of the left ventricular outflow tract (from the left high parasternal window) and the long-axis view of the aortic arch (from the suprasternal window). In Weinberg type A, the distal fifth and fourth aortic arches were connected to the descending aorta, which was associated with aortic coarctation. In Weinberg type B, the upper arch of the fourth aorta was interrupted, and only the lower arch of the fifth aorta was connected to the descending aorta. Surgical repair of PFAA was indicated in five patients with blood flow disruption, among which four had good postoperative results and one refused surgery. Two patients with unobstructed PFAA blood flow required follow-up rather than surgery. CONCLUSIONS: It is feasible to diagnose PFAA by echocardiography. Combined application of the high parasternal left ventricular outflow tract view and the suprasternal aortic arch view can improve timely detection of different types of PFAA in children.

RESUMEN

BACKGROUND: A left thoracotomy approach is anatomically appropriate for childhood aortic coarctation; however, the pediatric femoral arteriovenous diameters are too small for cardiopulmonary bypass cannulation. We aimed to determine the safety of a partial cardiopulmonary bypass through the main pulmonary artery and the descending aorta in pediatric aortic coarctation repair. METHODS: We retrospectively reviewed 10 patients who underwent coarctation repair under partial main pulmonary artery-to-descending aorta cardiopulmonary bypass with a left thoracotomy as the CPB group. During the same period, 16 cases of simple coarctation of the aorta repair, with end-to-end anastomosis through a left thoracotomy without partial CPB assistance, were included as the non-CPB group to evaluate the impact of partial CPB. RESULTS: The median age and weight at surgery of the CPB group were 3.1 years (range, 9 days to 17.9 years) and 14.0 (range, 2.8-40.7) kg, respectively. Indications for the partial cardiopulmonary bypass with overlap were as follows: age > 1 year (n = 7), mild aortic coarctation (n = 3), and predicted ischemic time > 30 min (n = 5). Coarctation repair using autologous tissue was performed in seven cases and graft replacement in three. The mean partial cardiopulmonary bypass time, descending aortic clamp time, and cardiopulmonary bypass flow rate were 73 ± 37 min, 57 ± 27 min, and 1.6 ± 0.2 L/min/m2, respectively. Urine output during descending aortic clamping was observed in most cases in the CPB group (mean: 9.1 ± 7.9 mL/kg/h), and the total intraoperative urine output was 3.2 ± 2.7 mL/kg/h and 1.2 ± 1.5 mL/kg/h in the CPB and non-CPB group, respectively (p = 0.020). The median ventilation time was 1 day (range, 0-15), and the intensive care unit stay duration was 4 days (range, 1-16) with no surgical deaths. No major complications, including paraplegia or recurrent coarctation, occurred postoperatively during a median observation period of 8.1 (range, 3.4-17.5) years in the CPB group. In contrast, reoperation with recurrent coarctation was observed in 2 cases in the non-CPB group (p = 0.37). CONCLUSIONS: Partial cardiopulmonary bypass through the main pulmonary artery and descending aorta via a left thoracotomy is a safe and useful option for aortic coarctation repair in children.

RESUMEN

Advancements in early diagnosis and paediatric cardiac surgery have improved the long-term survival of patients with congenital heart disease, necessitating a thorough assessment of their health-related quality of life (HRQoL). This study aimed to assess HRQoL in paediatric patients with coarctation of the aorta (CoA) (both as reported by patients and caregivers), and to evaluate associated factors. Patients aged 5-18 years diagnosed with CoA and their parents were enrolled at Bambino Gesù Children's Hospital between September 2016 and December 2017. Socio-demographic characteristics were recorded using a family form, and the Pediatric Quality of Life Inventory (PedsQL) 3.0 cardiac module was used to evaluate HRQoL. Clinical data were retrieved from medical chart reviews. In this observational study, sixty-five pediatric patients (39 males, median [IQR] age 12 [9-14]) with CoA and their parents (65 mothers and 65 fathers) were enrolled. These patients exhibited overall good HRQoL. Mothers reported significantly lower total HRQoL scores compared to patient self-reports (p = .037), as well as treatment anxiety (p = .033), and cognitive problems (p = .021). Pediatric patients with CoA perceived their HRQoL better than their mothers did. Female sex and older age were associated with lower HRQoL scores.

RESUMEN

The present study aimed to evaluate the outcomes of percutaneous treatment of aortic coarctation using self-expandable uncovered Nitinol stents. We conducted a retrospective clinical data review of all patients with aortic coarctation and treated with self-expandable uncovered Nitinol stents at our institution between 2009 and 2019. The gradient pressure across the coarctation site was measured using aortography. Follow-up echocardiography and computed tomography angiography were performed to assess possible stent complications. A total of 127 stents were successfully implanted in 125 patients (64.8% males) with a mean age of 35.36 ± 11.9 years. The gradient across the coarctation site decreased significantly from 67.48 ± 14.79 to 5.04 ± 3.01 mmHg (P < 0.001) after self-expandable stent implantation. Systolic blood pressure (SBP) decreased significantly from 175.53 ± 15.99 to 147.22 ± 12.83 mmHg (P < 0.001) after self-expandable stenting. There were no major technical or clinical complications, including balloon rupture, aneurysmal formation, infection, secondary stent migration, thrombosis, death during the procedure, and in-hospital mortality. On a mean follow-up of 48 ± 23.6 months (12-120 months), the gradient [from 59.43 ± 15.42 to 3.72 ± 1.38 mmHg (P < 0.001)] and SBP [from 175.53 ± 15.99 to 127.99 ± 7.82 mmHg (P < 0.001)] decreased significantly. There was no mortality, aneurysmal formation in the stent site, dislocation, or aortic re-stenosis requiring intervention during mid-term follow-up. Treatment of aortic coarctation using a self-expandable uncovered nitinol stent is safe and effective with promising mid-term outcomes.

RESUMEN

Aortic coarctation is diagnosed in approximately 5% of adult patients with congenital heart disease and is commonly diagnosed through the close examination of hypertension. Various surgical strategies for adult coarctation have been recently reported. Generally, aortic replacement may require blood transfusion in case of injury of the well-developed collateral vessels. Therefore, in order to secure an operative safety, we preoperatively used a medical image viewer to identify the abnormal vessels by three-dimensional computer graphics (3DCG) reconstruction. A 34-year-old male patient was referred to our hospital with hypertension and low ankle-brachial pressure index( ABI). Chest computed tomography( CT) scan showed aortic coarctation and development of abnormal collateral vessels. Descending aorta was replaced via a left third-fourth intercostal thoracotomy under partial extracorporeal circulation. As the image viewer depicted, anatomical abnormality of the collateral vessels was identified precisely, and surgically treated without any injury. The patient was discharged 10 days postoperatively without transfusion and with a normalized ABI.

RESUMEN

OBJECTIVE: This study aims to compare aortic morphology between repaired coarctation patients and controls, and to identify aortic morphological risk factors for hypertension and cardiovascular events (CVEs) in coarctation patients. METHODS: Repaired coarctation patients with computed tomography angiography (CTA) or magnetic resonance angiography (MRA) were included, followed-up and compared with sex-matched and age-matched controls. Three-dimensional aortic shape was reconstructed using patients' CTA or MRA, or four-dimensional flow cardiovascular magnetic resonance in controls, and advanced geometrical characteristics were calculated and visualised using statistical shape modelling. In patients, we examined the association of geometrical characteristics with (1) baseline hypertension, using multivariable logistic regression; and (2) cardiovascular events (CVE, composite of aortic complications, coronary artery disease, ventricular arrhythmias, heart failure hospitalisation, stroke, transient ischaemic attacks and cardiovascular death), using multivariable Cox regression. The least absolute shrinkage and selection operator (LASSO) method selected the most informative multivariable model. RESULTS: Sixty-five repaired coarctation patients (23 years (IQR 19-38)) were included, of which 44 (68%) patients were hypertensive at baseline. After a median follow-up of 8.7 years (IQR 4.8-15.4), 27 CVEs occurred in 20 patients. Aortic arch dimensions were smaller in patients compared with controls (diameter p<0.001, wall surface area p=0.026, volume p=0.007). Patients had more aortic arch torsion (p<0.001) and a higher curvature (p<0.001). No geometrical characteristics were associated with hypertension. LASSO selected left ventricular mass, male sex, tortuosity and age for the multivariable model. Left ventricular mass (p=0.014) was independently associated with CVE, and aortic tortuosity showed a trend towards significance (p=0.070). CONCLUSION: Repaired coarctation patients have a smaller aortic arch and a more tortuous course of the aorta compared with controls. Besides left ventricular mass index, geometrical features might be of importance in long-term risk assessment in coarctation patients.

RESUMEN

BACKGROUND: The exact prevalence and clinical significance of excessive increase in blood pressure in response to exercise in patients with repaired coarctation of aorta (CoA) remains unknown. AIM: This study aimed to investigate the impact of different definitions of exercise-induced hypertension (EIH) on the prevalence rates in our adult patients with repaired CoA. A systematic review of the available literature was also performed. METHODS: We retrospectively analyzed exercise test data from adult patients with repaired CoA followed at the national referral center for adult congenital heart disease between 1998 and 2021. The three most reported definitions of EIH in patients with repaired CoA were used for the analysis of EIH prevalence. We also performed a systematic search of the PubMed electronic bibliographic database. Full-text versions of all potentially relevant articles on EIH in CoA were reviewed for relevance. RESULTS: Our registry included 161 adult CoA patients. Complete exercise test results were available in 74 patients (59% male, median age 39 years [range 20-68 years]). The prevalence of EIH in our cohort varied from 24 to 41%, depending on the definition used. We identified eleven eligible articles from 184 publications. The reported prevalence rate of EIH in the studies ranged from 13% to 82%. CONCLUSION: EIH is common in patients with repaired CoA; however, the rates of EIH vary greatly depending on the definition used. A standardized and uniform EIH definition is needed to accurately assess the prevalence and clinical relevance of EIH in this population.

RESUMEN

ABSTRACT: Paraparesis following cardiac surgery is a manifestation of spinal cord injury (SCI). It can occur in any aortic surgery from the aneurysm to the coarctation of the aorta (CoA) where the cross-clamp of the aorta is applied. Though the incidence of paraplegia is low, its occurrence affects the morbidity and mortality of the patient. There are only sporadic case reports on the development of paraplegia following recurrent and technically challenging repair of CoA. However, the spontaneous development of paraplegia has also been reported in cases of unoperated CoA. The present report describes the case of delayed SCI in which paraparesis developed 5 days post a coarctation repair. The risk factors and strategies to protect the spinal cord during aortic surgeries are emphasized.

RESUMEN

OBJECTIVE: This study aimed to compare the effectiveness of resection and extended end-to-end anastomosis between neonate and infant patients with coarctation. METHODS: This study was designed retrospectively and included 41 neonate (<30 days) and infant (30 days to 1 year) patients who were operated on using the resection and extended end-to-end anastomosis technique for aortic coarctation. Preoperative aortic annulus diameters and Z scores, all aortic arch diameters and Z scores, the presence of hypoplastic aortic segment, and the presence of prematurity were reviewed in both groups. Subsequently, we investigated whether these parameters were statistically related to the residual gradient in the operation area, whether there was a need for early re-intervention, and what was the incidence of mortality in the early postoperative period. In addition, the aortic arch Z scores of the patients at 6 months postoperatively were examined. RESULTS: While the mean age (p<0.001), body weight (p<0.001), and proximal arch Z score (p=0.029) were found to be significantly lower in the neonate group than in the infant group, the total length of the intensive care unit stay (p=0.013) and the total length of hospital stay (p=0.017) were found to be significantly higher. In addition, significant enlargement was detected in the proximal arch, distal arch, and isthmus segments in both patient groups. CONCLUSION: The resection and extended end-to-end anastomosis is an equally effective technique that can provide a marked decrease in gradient in the coarctation area and a significant enlargement of the aortic arch segments in the early period after coarctation repair in both neonate and infant patients.

RESUMEN

The gold standard for assessing pressure gradients (PG) across coarctation involves measurements obtained through cardiac catheterization or surgical intervention. There has been ongoing discussion regarding the accuracy of non-invasive methods for estimating these gradients. This study sought to establish the correlation and agreement between the systolic blood pressure (SBP) gradient between the upper and lower extremities, as well as, the mean and maximum PG derived from echocardiography, in comparison to the peak-to-peak pressure gradient obtained from either cardiac catheterization or surgery. We conducted a retrospective study on patients < 18 years diagnosed with coarctation at Chiang Mai University Hospital from 2011 to 2022. The study involved the measurement of the SBP gradient between the upper and lower extremities, mean and maximum PG using echocardiography, peak-to-peak pressure gradient obtained from cardiac catheterization, and pressure gradient recorded during surgical procedures. The Spearman's correlation and Bland-Altman analysis were employed to assess correlation and agreement. Fifty-four patients with aortic coarctation were enrolled. The mean PG measured by echocardiography showed a significantly moderate correlation (r = 0.78, p < 0.001) and the highest level of agreement according to Bland Altman plots, in comparison to the peak-to-peak pressure gradient measured during both cardiac catheterization and surgical procedure. The max PG demonstrated a notable overestimation compared to the gold standard (mean difference + 13.14 with a slope of biases + 0.64, p < 0.001). The mean PG obtained through echocardiography has more potential to be applied in practical application in predicting pressure gradient in patients with coarctation.

RESUMEN

Objective: Hands-on surgical training (HOST) for congenital heart surgery (CHS), utilizing silicone-molded models created from 3D-printing of patients' imaging data, was shown to improve surgical skills. However, the impact of repetition and frequency of repetition in retaining skills has not been previously investigated. We aimed to longitudinally evaluate the outcome for HOST on two example procedures of different technical difficulties with repeated attempts over a 15-week period. Methods: Five CHS trainees were prospectively recruited. Repair of coarctation of the aorta (CoA) and arterial switch operation (ASO) were selected as example procedures of relatively low and high technical difficulty. Procedural time and technical performance (using procedure-specific assessment tools by the participant, a peer-reviewer, and the proctor) were measured. Results: Coarctation repair performance scores improved after the first repetition but remained unchanged at the follow-up session. Likewise, CoA procedural time showed an early reduction but then remained stable (mean [standard deviation]: 29[14] vs 25[15] vs 23[9] min at 0, 1, and 4 weeks). Conversely, ASO performance scores improved during the first repetitions, but decreased after a longer time delay (>9 weeks). Arterial switch operation procedural time showed modest improvements across simulations but significantly reduced from the first to the last attempt: 119[20] versus 106[28] min at 0 and 15 weeks, P = .049. Conclusions: Complex procedures require multiple HOST repetitions, without excessive time delay to maintain long-term skills improvement. Conversely, a single session may be planned for simple procedures to achieve satisfactory medium-term results. Importantly, a consistent reduction in procedural times was recorded, supporting increased surgical efficiency.

RESUMEN

Circumflex aortic arch with coarctation and anomalous origin of the left pulmonary artery from the aorta are rare cardiovascular anomalies. These conditions can lead to early pulmonary hypertension and challenging management. Early diagnosis and surgical intervention are beneficial for optimal outcome. We present a case where both anomalies coexisted and were repaired with aortic uncrossing, arch augmentation, and reimplantation of the left pulmonary artery. To our knowledge, this is the first documented instance of these anomalies coexisting and being repaired in the neonatal period.

RESUMEN

OBJECTIVE: To investigate the effect of improving the operative field and postoperative atelectasis of single-lung ventilation (SLV) in the surgical repair of coarctation of the aorta (CoA) in infants without the use of cardiopulmonary bypass (CPB). METHODS: This was a retrospective cohort study. The clinical data of 28 infants (aged 1 to 4 months, weighing between 4.2 and 6 kg) who underwent surgical repair of CoA without CPB from January 2019 to May 2022 were analyzed. Fourteen infants received SLV with a bronchial blocker (Group S), and the other 14 infants received routine endotracheal intubation and bilateral lung ventilation (Group R). RESULTS: In comparison to Group R, Group S exhibited improved exposure of the operative field, a lower postoperative atelectasis score (P<0.001), reduced prevalence of hypoxemia (P=0.01), and shorter durations of operation, mechanical ventilation, and ICU stay (P=0.01, P<0.001, P=0.03). There was no difference in preoperative information or perioperative respiratory and circulatory indicators before SLV, 10 minutes after SLV, and 10 minutes after the end of SLV between the two groups (P>0.05). Intraoperative bleeding, intraoperative positive end-expiratory pressure (PEEP), and systolic pressure gradient across the coarctation after operation were also not different between the two groups (P>0.05). CONCLUSION: This study demonstrates that employing SLV with a bronchial blocker is consistent with enhanced operative field, reduced operation duration, lower prevalence of intraoperative hypoxemia, and fewer postoperative complications during the surgical repair of CoA in infants without the use of CPB.
