RESUMEN

Introduction: Reconstruction surgery of the proximal aorta in most cases involves the use of an aortic conduit, followed by reimplantation of the coronary ostia. Although uncommon, the origin of the coronary arteries in certain anatomical variants poses additional difficulties when performing surgery on the aortic root and requires a different treatment rationale. Case report: We hereby present the case of a 60-year-old patient with multiple cardiovascular risk factors (smoking, arterial hypertension and dyslipidemia), suffering from severe degenerative stenosis of a bicuspid aortic valve, associated with ascending aorta aneurysm and a significant extrinsic stenosis of the left coronary artery caused by the aneurysm. The patient presented with severe degenerative bicuspid aortic valve stenosis associated with ascending aorta aneurysm and a significant extrinsic stenosis of the left coronary artery caused by the aneurysm. Following the preoperative assessment, it was decided that the best course of action was to perform surgery on the aortic valve and ascending aorta. During the surgery, the origin of the right and left coronary ostia were found at the level of the left coronary cusp, both forming a common coronary button. Due to this particular anatomical variant, it was decided to reimplant them as a common button onto the main conduit by means of an interposed No.10 PTFE (Polytetrafluoroethylene) vascular prosthesis. Conclusion: A rare case of aortic root surgery associated with coronary ostia origin variant "shotgun barrel", which required a different method of reimplantation: modified Cabrol technique.

RESUMEN

BACKGROUND: Inflammation following transcatheter aortic valve implantation (TAVI) is associated with an increased risk of adverse outcomes. The aim of this study was to compare the inflammatory response between low radial force valves (Acurate neo2, Boston Scientific) and high radial force valves (Evolut R/Pro, Medtronic; SAPIEN Edwards Lifesciences; and Myval, Meril valves). METHODS: We conducted a retrospective study of patients with severe aortic stenosis treated with TAVI between 2021 and 2022. The primary endpoint was the difference in the inflammatory response between low radial force valves and high radial force valves, measured as the difference between post-procedural and pre-procedural high-sensitivity C-reactive protein levels (hsCRP delta). RESULTS: A total of 114 patients were included, of which 65 patients (57%) received a low radial force valve. The hsCRP delta was lower in the low radial force valve group compared to the high radial force valve group (8.7 [2.1-15.6] mg/L vs. 18.8 mg/dL [6.4-19] mg/L; P=0.003), due to a lower post-implantation hsCRP (8.9 [5.45-19.6] mg/L vs. 15.8 [9.8-27.3] mg/L; P=0.013). The incidence of new left bundle branch block (LBBB) after TAVI was lower in the low radial force valve group compared to the high radial force valve group (11 [17%] vs. 18 [37%]; P=0.020). CONCLUSIONS: Low radial force TAVI prostheses were associated with a lower inflammatory response, and a lower incidence of new LBBB compared to the radial force valve group, suggesting that inflammation may contribute to the increased risk of conduction disturbances.

RESUMEN

BACKGROUND: Degenerative severe aortic valve stenosis (AS) is increasingly prevalent in the aging population, leading to the adoption of transcatheter aortic valve replacement (TAVR) as a less invasive alternative. While TAVR indications have expanded, the procedure is associated with a substantial incidence of major adverse cardiac events (MACE). The study aims to establish a preoperative risk-stratification system for TAVR candidates based on Sokolow-Lyon voltage (SLV) and other relevant factors. METHODS: A total of 181 consecutive patients who underwent TAVR were retrospectively reviewed. Baseline characteristics, preoperative electrocardiogram (ECG) and echocardiography findings, and TAVR procedures were assessed. Low SLV (<3.5 mV) was defined based on ECG measurements. RESULTS: Baseline characteristics revealed a mean age of 84 years, with 71.8% females. The two-year incidence of MACE defined as a composite of cardiac death and hospitalization due to heart failure, was 11.6%, significantly higher in the low SLV group. Low SLV emerged as an independent prognostic factor. The Tokyo Bay Risk (TBR) Score, including low SLV, Body Mass Index <18.5 kg/m2, and previous coronary artery disease, effectively stratified MACE risk. Higher TBR scores (2 or 3) correlated with increased MACE risk. CONCLUSIONS: Patients with low SLV in pre-procedural ECG demonstrated a heightened risk of two-year MACE. The TBR score, incorporating low SLV, proved valuable for preoperative risk assessment. Careful consideration of TAVR indications, along with TBR score integration, is crucial for optimizing outcomes.

RESUMEN

BACKGROUND: Paravalvular regurgitation (PVR) is a common complication after transcatheter aortic valve replacement, posing an increased risk of heart failure and mortality. Accurate intraprocedural quantification of PVR is challenging. Both hemodynamic indices and videodensitometry can be used for intraprocedural assessment of PVR. We compared the predictive value of the isolated versus combined use of the hemodynamic index diastolic delta (DD) and videodensitometry for the incidence of relevant PVR 1 month after transcatheter aortic valve replacement. METHODS AND RESULTS: In this prospective cohort study, patients underwent periprocedural PVR assessment by DD and videodensitometry (using left ventricular outflow tract-aortic regurgitation [LVOT-AR]). Cardiac magnetic resonance served as reference modality for PVR assessment. Relevant PVR was defined as cardiac magnetic resonance-regurgitant fraction >20%. Fifty-one patients were enrolled in this study. Mean age was 80.6±5.2 years and 45.1% of patients were men. Mean LVOT-AR and cardiac magnetic resonance-regurgitant fraction were 8.2%±7.8% and 11.7%±9.6%, respectively. The correlation between DD and LVOT-AR was weak (r=-0.36). DD and LVOT-AR showed a comparable accuracy to predict relevant PVR (area under the curve 0.82, 95% CI: 0.69-0.95 versus area area under the time-density curve 0.80, 95% CI: 0.62-0.99). The combination of DD and LVOT-AR improved the prediction of relevant PVR (area under the time-density curve, 0.90, 95% CI: 0.81-0.99), and resulted in an increased concordance (86.3%) and positive predictive value (75%) compared with DD alone (76.5% and 40%, respectively), or LVOT-AR alone (82.3% and 50%, respectively). CONCLUSIONS: DD and videodensitometry are both accurate and feasible modalities for the assessment of PVR after transcatheter aortic valve replacement. The synergistic use of both techniques increases the predictive value for relevant PVR after transcatheter aortic valve replacement.

RESUMEN

Aortic valve replacement (AVR) leads to reverse cardiac remodeling in patients with aortic stenosis (AS). The aim of this secondary pooled analysis was to assess the degree and determinants of changes in myocardial perfusion post AVR, and its link with exercise capacity, in patients with severe AS. A total of 68 patients underwent same-day echocardiography and cardiac magnetic resonance imaging with adenosine stress pre and 6-12 months post-AVR. Of these, 50 had matched perfusion data available (age 67 ± 8 years, 86% male, aortic valve peak velocity 4.38 ± 0.63 m/s, aortic valve area index 0.45 ± 0.13cm2/m2). A subgroup of 34 patients underwent a symptom-limited cardiopulmonary exercise test (CPET) to assess maximal exercise capacity (peak VO2). Baseline and post-AVR parameters were compared and linear regression was used to determine associations between baseline variables and change in myocardial perfusion and exercise capacity. Following AVR, stress myocardial blood flow (MBF) increased from 1.56 ± 0.52 mL/min/g to 1.80 ± 0.62 mL/min/g (p < 0.001), with a corresponding 15% increase in myocardial perfusion reserve (MPR) (2.04 ± 0.57 to 2.34 ± 0.68; p = 0.004). Increasing severity of AS, presence of late gadolinium enhancement, lower baseline stress MBF and MPR were associated with a greater improvement in MPR post-AVR. On multivariable analysis low baseline MPR was independently associated with increased MPR post-AVR. There was no significant change in peak VO2 post-AVR, but a significant increase in exercise duration. Change in MPR was associated with change in peak VO2 post AVR (r = 0.346, p = 0.045). Those with the most impaired stress MBF and MPR at baseline demonstrate the greatest improvements in these parameters following AVR and the magnitude of change in MPR correlated with improvement in peak VO2, the gold standard measure of aerobic exercise capacity.

RESUMEN

Surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) are options in severe aortic valve stenosis (AVS). Cardiovascular (CV) and cerebrovascular (CBV) control markers, derived from variability of heart period, systolic arterial pressure, mean cerebral blood velocity and mean arterial pressure, were acquired in 19 AVS patients (age: 76.8 ± 3.1 yrs, eight males) scheduled for SAVR and in 19 AVS patients (age: 79.9 + 6.5 yrs, 11 males) scheduled for TAVI before (PRE) and after intervention (POST, <7 days). Left ventricular function was preserved in both groups. Patients were studied at supine resting (REST) and during active standing (STAND). We found that: (i) both SAVR and TAVI groups featured a weak pre-procedure CV control; (ii) TAVI ensured better CV control; (iii) cerebral autoregulation was working in PRE in both SAVR and TAVI groups; (iv) SAVR and TAVI had no impact on the CBV control; (v) regardless of group, CV and CBV control markers were not influenced by STAND in POST. Even though the post-procedure preservation of both CV and CBV controls in TAVI group might lead to privilege this procedure in patients at higher risk, the missing response to STAND suggests that this advantage could be insignificant.

RESUMEN

A 3-month-old baby girl presenting with heart failure was found to have a large persistent ductus arteriosus as well as a bicuspid aortic valve with severe aortic stenosis. She underwent surgical ductal closure following which there was complete resolution of aortic valve gradients without requiring any aortic valve intervention. This case highlights the importance of understanding hemodynamics in efficacious management of congenital heart disease.

RESUMEN

This is a 15-year-old, 73.5 kg male who was born with congenital aortic valve stenosis. He underwent a transcatheter balloon aortic valvuloplasty in the neonatal period, followed by an open aortic valvotomy at 2 months of age. When he was 3 years old, he underwent aortic root replacement with a 15 mm aortic homograft. Recently, he presented with recurrent left ventricular outflow tract obstruction that appeared valvular and subvalvular in nature. We present our technique of repeat aortic root replacement and left ventricular outflow tract enlargement using modified Bentall combined with Konno-Rastan aortoventriculoplasty.

RESUMEN

BACKGROUND: Research on the role of transcatheter heart valve (THV) deformation and calcium distribution in patients with bicuspid aortic valves (BAVs) undergoing transcatheter aortic valve replacement (TAVR) remains limited. OBJECTIVES: The aim of this study was to evaluate the impact of THV deformation on clinical outcomes in individuals with BAVs undergoing TAVR and the influence of calcium on these outcomes. METHODS: In total, 229 consecutive patients with BAVs who underwent TAVR with balloon-expandable valves and had computed tomography (CT) performed 30 days post-TAVR were analyzed. Patients were stratified into 3 groups: group 1 (n = 125), with no THV underexpansion or eccentricity; group 2 (n = 69), with underexpansion or eccentricity; and group 3 (n = 35), with both. Calcium distribution was assessed using CT, and its associations with clinical outcomes, including all-cause mortality at 3 years and leaflet thrombosis at 30 days, were determined. A subgroup analysis of patients with type 1 BAVs was conducted. RESULTS: Group 3 exhibited higher rates of all-cause mortality than the other groups, along with the highest risk for hypoattenuated leaflet thickening at 30 days. Multivariate analysis identified annular and left ventricular outflow tract calcification as independent predictors of all-cause mortality and hypoattenuated leaflet thickening. In patients with type 1 BAVs, excessive calcification at the raphe and opposite leaflet were associated with all-cause mortality at 3 years. CONCLUSIONS: THV deformation post-TAVR was significantly linked to all-cause mortality in patients with BAVs. Annular and left ventricular outflow tract calcification correlated with increased risks for all-cause mortality and leaflet thrombosis.

RESUMEN

BACKGROUND: Fluid overload (FO) subjects patients with severe aortic stenosis (AS) to increased risk for heart failure and death after valve replacement and can be objectively quantified using bioimpedance spectroscopy (BIS). OBJECTIVES: The authors hypothesized that in AS patients with concomitant FO, BIS-guided decongestion could improve prognosis and quality of life following transcatheter aortic valve replacement (TAVR). METHODS: This randomized, controlled trial enrolled 232 patients with severe AS scheduled for TAVR. FO was defined using a portable whole-body BIS device according to previously established cutoffs (≥1.0 L and/or ≥7%). Patients with FO (n = 111) were randomly assigned 1:1 to receive BIS-guided decongestion (n = 55) or decongestion by clinical judgment alone (n = 56) following TAVR. Patients without FO (n = 121) served as a control cohort. The primary endpoint was the composite of hospitalization for heart failure and/or all-cause death at 12 months. The secondary endpoint was the change from baseline to 12 months in the Kansas City Cardiomyopathy Questionnaire. RESULTS: The occurrence of the primary endpoint at 12 months was significantly lower in the BIS-guided vs the non-BIS-guided decongestion group (7/55 [12.7%, all deaths] vs 18/56 [32.1%, 9 hospitalizations for heart failure and 9 deaths]; HR: 0.36; 95% CI: 0.15-0.87; absolute risk reduction = -19.4%). Outcomes in the BIS-guided decongestion group were identical to the euvolemic control group (log-rank test, P = 0.7). BIS-guided decongestion was also associated with a higher increase in the Kansas City Cardiomyopathy Questionnaire score from baseline compared to non-BIS-guided decongestion (P = 0.001). CONCLUSIONS: In patients with severe AS and concomitant FO, quantitatively guided decongestive treatment and associated intensified management post-TAVR was associated with improved outcomes and quality of life compared to decongestion by clinical judgment alone.
