RESUMO

OBJECTIVES: The aims of the present study were to compare the long-term outcomes for ascending aortic dilatation and adverse aortic events after isolated aortic valve replacement between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve ( TAV). METHODS: This retrospective study included 310 patients who had undergone isolated aortic valve replacement with an ascending aorta diameter ≤ 45 mm between January 2010 and September 2021. The patients were divided into BAV group (n=90) and TAV group (n=220). The differences in the dilation rate of the ascending aorta and long-term outcomes were analyzed. RESULTS: Overall survival was 89 ± 4% in the BAV group vs. 75 ± 6% in the TAV group at 10 years postoperatively (P=0.007), yet this difference disappeared after adjusting exclusively for age (P=0.343). The mean annual growth rate of the ascending aorta was similar between the two groups during follow-up (0.5 ± 0.6 mm/year vs. 0.4 ± 0.5 mm/year; P=0.498). Ten-year freedom from adverse aortic events was 98.1% in the BAV group vs. 95.0% in the TAV group (P=0.636). Multivariable analysis revealed preoperative ascending aorta diameter to be a significant predictor of adverse aortic events (hazard ratio: 1.76; 95% confidence interval: 1.33 to 2.38; P<0.001). CONCLUSION: Our study revealed that the long-term survival and the risks of adverse aortic events between BAV and TAV patients were similar after isolated aortic valve replacement. BAV was not a risk factor of adverse aortic events.

RESUMO

INTRODUCTION: Aortic valve replacement (AVR) is often recommended for patients with severe aortic stenosis or chronic aortic regurgitation. These conditions result in remodeling of the left ventricle, including increased interstitial fibrosis that may persist even after AVR. These structural changes impact left ventricular (LV) mechanics, causing compromised LV diameter to occur earlier than reduced LV ejection fraction (LVEF). The aim of this study was to examine the effect of left ventricular end-diastolic diameter (LVEDD) and its role in aortic expansion one year after AVR. METHODS: Sixty-three patients who underwent AVR were evaluated. All patients underwent standard transthoracic echocardiography, which included measurements of the ascending aorta, aortic root, LVEF, and LVEDD before the surgery and one year postoperatively. Correlations between these variables were calculated. RESULTS: All patients underwent AVR with either a mechanical or biological prosthetic aortic valve. Following AVR, there was a significant decrease in the dimensions of the ascending aorta and aortic root (both P=0.001). However, no significant changes were observed in LVEDD and LVEF. Correlations were found between the preoperative ascending aortic size and the preoperative and one-year postoperative LVEDD (r=0.419, P=0.001 and r=0.320, P=0.314, respectively). Additionally, there was a correlation between the postoperative ascending aortic size and the preoperative and one-year postoperative LVEDD (r=0.320, P=0.003 and r=0.136, P=0.335, respectively). CONCLUSION: The study findings demonstrate a significant correlation between the size of the aortic root and ascending aorta, before and after AVR. Additionally, a notable correlation was observed between postoperative LVEDD and the size of the aortic root.

RESUMO

We demonstrated an endovascular technique excluding an ascending aorta pseudoaneurysm using an aortic extension. A 32-year-old woman, 3 years after lung transplantation with extracorporeal membrane oxygenation presented with an ascending aortic pseudoaneurysm. Vascular surgery was consulted after open repair was deemed high risk. An aortic extension stent graft was placed in a hybrid operating room with the aid of intraoperative transesophageal echocardiography. Ascending aorta pseudoaneurysms are complex and life-threatening complications. Traditional repair involves high surgical and anesthetic risks whereas endovascular treatment is technically feasible.

RESUMO

Abstract Ascending aortic pathologies may be life-threatening. Postoperative aortic root dehiscence is a very rare but extremely dangerous complication with a high mortality rate, and redo surgery is mandatory due to high risk of spontaneous rupture. We present three cases that had undergone Bentall procedure and had postoperative aortic root dehiscence. One of the patients presented with hemiplegia caused by septic embolus while the others had mild symptoms. Dr. Yakut's modified Bentall procedure, the flanged technique, was performed for each patient in redo surgery. Two patients were successfully discharged from the hospital, but one died due to intracranial hemorrhage and multiple organ failure.

RESUMO

Iatrogenic acute aortic dissections during percutaneous coronary interventions are an extremely rare but potentially life-threatening complication, occurring in less than 0.02% of transcatheter procedures. We report three patients with different characteristics suffering from iatrogenic aortic dissection during percutaneous coronary intervention successfully treated with an emergency open-heart surgery. A conservative strategy should be pursuit only in small, localized lesions.

RESUMO

Resumen Para la reconstrucción y el tratamiento de anomalías que comprometen la aorta torácica pueden emplearse diversas técnicas quirúrgicas abiertas, las cuales estarán determinadas por la patología que presente el paciente. La angiotomografía computada multicorte (ATCMC) es el método de elección para su control y seguimiento. El médico radiólogo debe estar familiarizado con las técnicas quirúrgicas empleadas (Wheat, Bentall de Bono, Cabrol, entre otras), con las reparaciones estructurales que se realizan y con los materiales protésicos utilizados con el fin de evitar una interpretación errónea de las imágenes. El fieltro espontáneamente hiperdenso, los conductos protésicos y sus anastomosis, tanto con la aorta como con los grandes vasos, puede generar errores en el informe final y en el diagnóstico.


Abstract Multiple surgical techniques can be used for the reconstruction and treatment of abnormalities that compromise the thoracic aorta, which will be determined by the patient’s pathology. Multislice computed tomography angiography is the method of choice for their control and monitoring. The radiologist should be familiar with the surgical techniques used (Wheat, Bentall de Bono, and Cabrol, among others), as well as with the structural repairs that are performed and the prosthetic materials used in order to avoid an erroneous interpretation of the images. Spontaneously hyperdense felt, the prosthetic ducts and their anastomosis, both with the aorta and the large vessels, can generate pitfalls in the final report and error in the diagnosis.

RESUMO

A 70-year-old woman with a bioprosthetic aortic valve replacement for aortic valve endocarditis complicated by recurrent endocarditis and requiring homograft aortic root replacement 10 years earlier had presented at 1 month after her admission for pseudomonal bacteremia with right-sided chest pain. An aortic pseudoaneurysm, identified on computed tomography, was treated with an ascending aorta thoracic endovascular aortic repair using two overlapping abdominal aortic stent grafts in the ascending aorta. Postoperative and follow-up imaging demonstrated exclusion of the pseudoaneurysm with stable positioning of the stent grafts. Ascending aorta thoracic endovascular aortic repair can be performed safely with good short-term results in patients presenting with infected pseudoaneurysms of the ascending aorta.

RESUMO

OBJECTIVE: Surgery for ascending aneurysms in bicuspid aortic valve syndrome primarily includes Bentall root replacement, aortic valve replacement with supracoronary ascending aorta replacement (AVRSCAAR), and valve-sparing root reimplantation (VSRR). Comparative analysis of long-term clinical and functional outcomes of these procedures is detailed. METHODS: From 1997 to 2017, 635 patients with bicuspid aortic valve undergoing root complex-focused procedures electively were stratified by valvulopathy (ie, aortic stenosis vs aortic insufficiency) and substratified into ascending or root aneurysm phenotype. Inverse probability weights were calculated to adjust for baseline differences. RESULTS: Kaplan-Meier curves for all-cause mortality demonstrated no difference between Bentall versus AVRSCAAR for aortic stenosis and aortic insufficiency presentations (log-rank P > .05). In patients with aortic stenosis, multivariable Cox regression showed significantly decreased risk of stroke for biologic AVRSCAAR (hazard ratio, 0.04; P = .013). Aortic reoperation rates were similar for biologic versus mechanical valves (P = .353). In patients with aortic insufficiency, similar long-term mortality (hazard ratio, 0.95; P = .93), but lower stroke risk in biologic AVRSCAAR group by Cox regression, and lower aortic reoperation rate was noted (coefficient < 0.01; P < .001). Comparing Bentall to VSRR, mortality (hazard ratio, 0.12; P = .022) was significantly improved in patients undergoing VSRR, but recurrence of moderate or greater aortic insufficiency was higher in VSRR by multistate model (beta coefficient 2.63; P < .001). CONCLUSIONS: A tailored approach to heterogeneous ascending aneurysm pathologies in bicuspid aortic valve syndrome utilizing Bentall, AVRSCAAR, and VSRR procedures renders excellent long-term clinical and functional outcomes, with biologic conduits showing equivalent to improved clinical outcomes.

RESUMO

Abstract Although aortic valve replacement remains the gold standard treatment for aortic valve diseases like stenosis (AS) or insufficiency, new surgical methods have been developed with a focus in the reconstruction of the aortic valve rather than replacing it. The Ozaki procedure involves a tailored replacement of each individual valvular leaflet with glutaraldehyde-treated autologous pericardium and aims to reproduce the normal anatomy of the aortic valve. Cases of patients with unicuspid aortic valve treated with the Ozaki procedure are uncommon in the litrature and become even more rare when it comes to concomitant diseases like AS and ascending aorta aneurysm. We present the case of a 21-year-old, fit and asymptomatic male, with unicuspid aortic valve with severe stenosis and ascending aorta dilatation, surgically treated with tricuspidization of the aortic valve with glutaraldehyde-treated autologous pericardium and replacement of the ascending aorta with a straight synthetic graft. Postoperative studies showed a fully functional, neo-tailored tricuspid aortic valve with trivial regurgitation. The patient had an uncomplicated recovery, stayed in the intensive care unit for 2 days and was discharged on the 7th postoperative day.

RESUMO

The ascending aorta and arch have until recently been one of the last bastions of cardiovascular surgery, where life-threatening diseases impose the need for prompt correction and reversal of the impending adverse prognosis. Though a disease where dogmatic recommendations prevail, with upfront surgical intervention in the mind of every physician, type A acute aortic dissection (AAD) is a subject still blurred with many uncertainties. Endovascular intervention for the treatment of type A AAD is rapidly progressing and utilization of transcatheter therapies in the ascending aorta for treating type A AAD has demonstrated technical success in small studies, low early mortality rates, and relatively acceptable aorta-related mortality rates in the long term. These findings strengthen the preponderant role of the endovascular heart surgeon in the management of these procedures, where a combination of wire skill training and surgical proficiency encompassing all technical options available makes it distinctive and resourceful, which provides complete resolution to each multicomponent of this disease in one setting, besides the promptness to repair the inherent complications that will accompany these interventions. Transcatheter procedures and open surgery will coexist side by side and be regarded as complementary rather than competing. Substantial more refinement and technological innovation will be necessary before endovascular repair of type A AAD comes to widespread use, the ideal timespan for cardiovascular surgeons to be involved, and prepared to take on the challenges of leading this new enterprise.

RESUMO

Treatment of ascending aorta disease is surgical; however, some series have evaluated the effectiveness of endovascular treatment. We report the case of a patient with a ruptured pseudoaneurysm who underwent endovascular repair via the left common carotid artery. The clinical and neurological evolution was satisfactory during the in-hospital follow-up. (Level of Difficulty: Intermediate.).

RESUMO

Regardless the successful treatment of the descending aorta with endovascular prosthesis, for the ascending aorta segment, because of several anatomic and physiologic issues, this technique has been considered an alternative only for high-risk or inoperable patients. Despite restricted indications, hundreds of treatments have been performed worldwide, demonstrating its safety and reproducibility if it is done in high-quality centers. Therefore, understanding patients' selection criteria and technique limitations are critical to its application.

RESUMO

RESUMEN El pseudoaneurisma de aorta ascendente, como complicación en cirugía cardíaca, tiene una incidencia menor del 0,5%, pero una mortalidad que varía del 6,7 al 60%. La manipulación aórtica y la infección son los principales factores predisponentes. Su clínica puede ser variada y constituir un hallazgo casual en controles posteriores. Se presenta el caso de una paciente operada de cirugía valvular mitral que a los 11 meses del postoperatorio se le diagnostica un pseudoaneurisma de aorta ascendente, que requirió tratamiento quirúrgico de emergencia. La cirugía fue llevada a cabo con la utilización de canulación periférica extramediastínica, sin requerir parada circulatoria, ni hipotermia para su correcta disección. El caso muestra una variante técnica para enfrentar una enfermedad poco frecuente, pero altamente desafiante, por la necesidad de reintervención y una correcta estrategia quirúrgica.


ABSTRACT False ascending aortic aneurysm, as a complication in cardiac surgery, has an incidence of less than 0.5%, but a mortality that ranges from 6.7% to 60%. Aortic manipulation and infection are the main predisposing factors. Its clinical presentation is non-specific and may be found incidentally on subsequent check-ups. The case of a patient undergoing mitral valve surgery who was diagnosed with ascending aortic false aneurysm, eleven months after postoperative period, requiring emergency surgical treatment is presented. The surgery was performed using extra-mediastinal peripheral cannulation, without induced circulatory arrest or hypothermia for proper dissection. The case shows a technical version to face an uncommon but highly challenging disease as it needs re-interventions and successful surgical strategies.

RESUMO

RESUMEN Introducción: Los aneurismas de aorta ascendente son lesiones que deben tratarse quirúrgicamente debido a sus complicaciones potencialmente mortales, como la ruptura y la disección. Objetivos: Revisar los resultados a corto y mediano plazo del tratamiento quirúrgico en pacientes con aneurisma de aorta ascendente. Método: Se revisaron retrospectivamente las historias clínicas de 78 pacientes que recibieron tratamiento quirúrgico debido a un aneurisma de aorta ascendente, entre agosto de 2006 y julio de 2018, en el hospital Erzurum Regional Training and Research Hospital. Resultados: La edad promedio de los pacientes fue de 51,7 ± 9,8 (rango 24-77 años). Hubo 54 (69,2%) hombres y 24 (30,8%) mujeres. Cincuenta y ocho pacientes (74,3%) tenían síndrome de Marfan. También se encontraron enfermedad coronaria (15,4%), estenosis mitral (3,8%), insuficiencia (11,5%), estenosis (8,9%) y coartación aórticas (2,6%). Se realizó tratamiento quirúrgico de emergencia en 41 pacientes (52,5%). Se reemplazó la aorta ascendente en 55 pacientes (70,5%). Se empleó la técnica de Bentall (17,9%) y sustitución valvular aórtica más reemplazo de aorta ascendente con injerto (11,5%). En 14 pacientes se utilizó paro anóxico (parada circulatoria total). La mortalidad operatoria fue de 3,8% (3 pacientes) con la técnica de Bentall y la mortalidad postoperatoria temprana fue de 1,3% (1 paciente con coartación aórtica). Conclusiones: Los pacientes con aneurisma de aorta ascendente deben tener un estrecho seguimiento para definir su momento quirúrgico, debido al riesgo de disección y rotura. Aunque se pueden aplicar varias técnicas quirúrgicas de acuerdo con el estado de la válvula aórtica, especialmente en pacientes con síndrome de Marfan, el procedimiento quirúrgico preferido debería ser el reemplazo de la raíz aórtica con injerto compuesto, con el uso de la técnica de Bentall modificada, con reimplantación de los ostium de las arterias coronarias en el injerto.


ABSTRACT Introduction: Ascending aortic aneurysms are lesions that should be surgically handled because of their life-threatening complications like rupture and dissection. Objectives: To examine the early and midterm outcomes of surgical treatment in patients with ascending aortic aneurysm. Method: We retrospectively examined the records of 78 patients who underwent surgical treatment due to ascending aortic aneurysm between August 2006 and July 2018 at Erzurum Regional Training and Research Hospital. Results: The patients' average age was 51.7 ± 9.8 (ranged 24-77 years). There were 54 (69.2%) men and 24 (30.8%) women. Fifty-eight (74.3%) patients had Marfan's Syndrome. They also presented coronary artery disease (15.4%), mitral stenosis (3.8%), aortic regurgitation (11.5%), aortic stenosis (8.9%), and aortic coarctation (2.6%). The emergency surgical treatment was required in 41 (52.5 %) patients. Only 55 (70.5 %) patients had performed ascending aortic replacement. Bentall procedure (17.9%) and aortic valve replacement + ascending aortic graft replacement (11.5%) were performed. In 14 patients totally circulatory arrest was used. The operative mortality occurred in 3 (3.8%) patients with Bentall procedure and the early postoperative mortality occurred in 1 (1.3%) patient with aortic coarctation. Conclusions: Patients with ascending aortic aneurysms should be closely monitored for the timing of surgery due to the risk of dissection and rupture. Although various surgical techniques can be applied according to the aortic valve status, especially in patients with Marfan's Syndrome, root replacement with composite graft, and Bentall modifications and button anastomosis of coronary arteries in composite graft applications should be the preferred surgical procedure.

RESUMO

A 67-year-old man presented with chest pain. Clinical examination revealed hypertension (160/90 mm Hg). Electrocardiogram indicated no acute coronary syndrome and cardiac enzymes were normal. Catheterization was performed owing to the patient's continuing chest pain and ascending aortogram revealed irregular aortic wall. A computed tomography image showed the shape of penetrating ulcer. The patient was taken to the operating room and intraoperative examination confirmed the diagnosis of penetrating atherosclerotic ulcer (PAU). Coronary artery bypass graft and bovine pericardial patch repair of PAU was performed. A bovine pericardial patch was done as aortic root was heavily calcified and was easy to handle and more hemostatic.
