Background: Bicuspid aortic valve is the most common congenital heart defect and predisposes patients to developing aortic stenosis more frequently and at a younger age than the general population. However, the influence of bicuspid aortic valve on the rate of progression of aortic stenosis remains unclear. Methods: In 236 patients (177 tricuspid aortic valve, 59 bicuspid aortic valve) matched by initial severity of mild or moderate aortic stenosis, we retrospectively analyzed baseline echocardiogram at diagnosis with latest available follow-up echocardiogram. Baseline comorbidities, annualized progression rate of hemodynamic parameters, and hazard of aortic valve replacement were compared between valve phenotypes. Results: Median echocardiographic follow-up was 2.6 (IQR 1.6-4.2) years. Patients with tricuspid aortic stenosis were significantly older with more frequent comorbid hypertension and congestive heart failure. Median annualized progression rate of mean gradient was 2.3 (IQR 0.6-5.0) mmHg/year vs. 1.5 (IQR 0.5-4.1) mmHg/year (p=0.5), and that of peak velocity was 0.14 (IQR 0-0.31) m/s/year vs. 0.10 (IQR 0.04-0.26) m/s/year (p=0.7) for tricuspid vs. bicuspid aortic valve, respectively. On multivariate analyses, bicuspid aortic valve was not significantly associated with more rapid progression of aortic stenosis. In a stepwise Cox proportional hazards model adjusted for baseline mean gradient, bicuspid aortic valve was associated with increased hazard of aortic valve replacement (HR: 1.7, 95% CI [1.0, 3.0], p=0.049). Conclusion: Bicuspid aortic valve may not significantly predispose patients to more rapid progression of mild or moderate aortic stenosis. Guidelines for echocardiographic surveillance of aortic stenosis need not be influenced by valve phenotype.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Aortic stenosis (AS) is the most prevalent valvular heart disease among the elderly, reaching 8,1% in 85 years-old patients. Symptomatic severe AS entails a high risk of morbidity and mortality without valve replacement, and increasing age is associated with higher surgical risk. Purpose To determine the prognostic impact of advanced age in patients with severe AS referred to surgical valve replacement. Methods We conducted a retrospective study encompassing patients referred to surgical aortic valve replacement due to severe AS, from January 2016 to December 2018. Clinical characteristics, diagnostic studies and follow-up were analysed. Patients were divided in two groups according to the age: <80 and ≥80 years old. Independent predictors of mortality and/or re-hospitalization were identified through a binary logistic regression analysis, considering p = 0,05. Results A total of 222 patients were included, with a 64,4% male predominance and a median age of 75 years old. 27,5% had concomitant surgical coronary artery disease and 87,4% waited in an out-patient setting. Median delay until surgery was 87 days and median follow-up after surgical referral was 517 days. 59 patients (26,8%) had ≥ 80 years old. Male gender (69,6% vs 50,8%; p = 0,01), smoking habits (14,3% vs 1,7%; p = 0,024), higher glomerular filtration rate (75,5 vs 63,2 ml/min; p = 0,001) and lower Euroscore II values (2,89% vs 4,64%; p = 0,003) were more common in younger patients. Global mortality rate (27,1% vs 15,5%; p = 0,05) and the composite of mortality or re-hospitalization (52,5% vs 36,6%; p = 0,034) were more frequent in older patients. Despite re-hospitalizations were also more common (37,3% vs 29,2%), they did not reach statistical significance (p = 0,252). After multivariate analysis, advanced age was not an independent predictor of mortality and/or re-hospitalization. In this population, only the presence of extracardiac arteriopathy (p = 0,007; p = 0,006) and pulmonary hypertension (p = 0,004; p = 0,002) were both independent predictors of mortality and the composite of mortality or re-hospitalization. Conclusion Older patients with AS have higher mortality, but advanced age was not an independent predictor of mortality and/or re-hospitalization. The decision to perform aortic valve replacement should be discussed in the Heart Team, considering patient’s comorbidities and performing a comprehensive geriatric evaluation, not just focusing on age itself.

Background: Sutureless-surgical aortic valve replacement (SU-SAVR) has been proposed as a surgical alternative for treating aortic stenosis, which facilitates a minimally invasive approach. While some studies have compared the early outcomes of SU-SAVR versus transcatheter aortic valve replacement (TAVR), most data were obtained in high-risk patients and/or limited to in-hospital outcomes. This study aimed to compare in-hospital and midterm clinical outcomes following SU-SAVR and TAVR in low-risk patients with aortic stenosis. Methods: A total of 806 consecutive low-risk (EuroSCORE II <4%) patients underwent TAVR or SU-SAVR between 2011 and 2020 in 2 centers. A 1:1 propensity score matching was performed and identified 171 pairs with similar characteristics that were included in the analysis. Baseline characteristics, in-hospital and follow-up events (defined according to Valve Academic Research Consortium-2) were collected. Results: Baseline characteristics were well balanced between groups, with a median EuroSCORE II of 1.9% (1.3%–2.5%) in both SU-SAVR and TAVR groups ( P =0.85). There were no statistically significant differences regarding in-hospital mortality (SU-SAVR: 4.1%, TAVR: 1.8%, P =0.199) and stroke (SU-SAVR: 2.3%, TAVR: 2.9%, P =0.736), but SU-SAVR recipients exhibited higher rates of bleeding and new-onset atrial fibrillation, higher residual transvalvular gradients ( P <0.001), and a lower rate of pacemaker implantation ( P =0.011). After a median follow-up of 2 (1–3) years, there were no differences between groups in all-cause mortality (hazard ratio, 0.97 [95% CI, 0.52–1.82], P =0.936) and stroke (hazard ratio, 0.83 [95% CI, 0.32–2.15], P =0.708), but SU-SAVR was associated with a higher risk of heart failure hospitalization (hazard ratio, 5.38 [95% CI, 1.88–15.38], P =0.002). Conclusions: In low-risk patients with aortic stenosis, TAVR was associated with improved in-hospital outcomes (except for conduction disturbances) and valve hemodynamics, compared with SU-SAVR. Although similar mortality and stroke rates were observed at 2-year follow-up, the risk of heart failure hospitalization was higher among SU-SAVR patients. These results may contribute to reinforce TAVR over SU-SAVR for the majority of such patients.

Background: Morphological changes of the proximal aorta, such as effacement of the sinotubular junction (STJ), may result in increased mechanical stress on the aortic valve leaflets and contribute to calcification and progression of aortic stenosis (AS). The aim of this study was to examine the association between abnormal morphology of proximal aorta and AS progression rate. Methods: Between 2010 and 2012, 426 patients with mild to moderate AS (peak aortic jet velocity >2.5 and <4 m/s) and LVEF≥50% with at least two years of follow up were included in this study. Aortic dimensions were measured at 3 different levels: sinus of Valsalva (SVal), STJ and ascending aorta (Aa). The ratios of SVal by STJ (SVal/STJ) and Aa by STJ (Aa/STJ) were used to determine degree of aortic deformity with smaller ratios consistent with greater perturbation of normal geometry. SVal/STJ<1.13 and Aa/STJ<1.09 were defined as significant low ratios per normal range reported in Guidelines. AS progression rate was assessed by annualized increase in mean gradient (MG; follow-up time = 3.2±0.8 yrs). Results: Mean age was 71±13 yrs and 64% were male. 16% had bicuspid aortic valve and MG was 21±8 mmHg. SVal, STJ and Aa dimensions were respectively 33±4 mm, 27±4 mm and 36±5 mm. Mean SVal/STJ ratio was 1.21±0.15 and Aa/STJ ratio was 1.29±0.19. Patients with significant low ratios had faster AS progression (p≤0.05; figure). After adjustment for age, gender, hypertension, diabetes, renal disease, bicuspid aortic valve, baseline MG, LVEF, aortic regurgitation and indexed STJ, SVal/STJ (p=0.025) or Aa/STJ (p=0.027) were independently associated with faster AS progression. Conclusion: Abnormal aortic root geometry such as effacement of the sinotubular junction is a strong and independent predictor of faster AS progression, regardless of arterial hemodynamics, aortic valve phenotype and baseline AS severity. This finding suggests an interrelation between proximal aorta morphology and stenosis progression.

Abstract Transcatheter Aortic valve Replacement (TAVR) has emerged as an alternative to surgical aortic valve replacement for patients considered at high or prohibitive operative risk. It is widely known the short and mid-term outcomes, however, is limited about long-term outcomes in according to age. The aim of this study was to determine the survival and the clinical outcomes on based of age. after TAVR with the CoreValve prosthesis. Methods From April 2008 to December 2017, the CoreValve and Sapiens 3 prosthesis were implanted in 667 patients with symptomatic severe aortic stenosis with deemed high risk on base to age, <80 years and ≥80 years old Results The mean age in patients <80 compared with ≥80 years, was 73.6±7 vs. 83.4±2.8 years and the logistic EuroSCORE and STS score were 16.3±11% vs. 18.1±11%. In-hospital mortality was 3.4%, and the combined endpoint of death, vascular complications, myocardial infarction, majopr bleeding or stroke had a rate of 18.3%. The late mortality (beyond 30 days) was 40.5%. When compared both groups, there were no differences for the presence of threatening bleeding 3.5% vs. 3.6% (HR = 1.033 [IC95% 0.452–2.360], p=0.557), myocardial infarction4.2% vs. 2.9% (HR = 0.67 [IC95% 0.290–1,530], p=0.0.226), stroke 8.9% vs. 9.4% (HR = 1.067 [IC95% 0.625–1.821], p=0.814) and mortality 44.5% vs. 41.1% (HR=0.971388 [IC95% 0.639–1.188], p=0.214) and there was difference in between groups in hospitalizations for heart failure 13.8% vs. 7.7% (HR = 1.374 [IC95% 1.037–1.821], p=0.008. Survival at 1, 2, 3, 4, 5 were similar in both groups (86.9% vs. 89.8%, 78.4 vs. 78.3%, 65.5 vs. 72.5%, 57.9% vs. 62.8% and 51.1 vs. 52.8%>; log Rank 0.992, p=0.319), respectively, after a mean follow-up of 43.9±27 months. Conclusions TAVR is associated with significant survival benefit throughout 3.2 years of follow-up. Survival during follow-up was similar in patients with <80 compared with ≥80 years old.

A bicuspid aortic valve (BAV) can be a serious disorder of heart valve in which the valve only has two leaflets or flaps that control blood flow through the heart. Between one and two percent of all people have this defect and it affects more men than women. This report presents a case of severe aortic stenosis with mild to moderate aortic regurgitation due to bicuspid aortic valve with hypertension. A 37 years old male presented with high record of blood pressure and occasional shortness of breath on exertion. Echocardiography (Color Doppler) revealed severe aortic stenosis with mild to moderate aortic regurgitation due to bicuspid aortic valve with moderately severe concentric LV wall hypertrophy. Surgical treatment (aortic valve replacement) was scheduled based on echocardiography findings. On surgical resection a well defined bicuspid aortic valve was found with calcification and friable valve leaflet. Histopathology of valve tissue shows large areas of calcification. Patient was discharged from hospital on 7th POD with an advice to attend cardiac surgery OPD after 1 month. Aortic valve replacement must be considered in this type of lesion.Bangladesh Med J. 2015 May; 44 (2): 105-108
