“…In a retrospective study of elderly patients undergoing aortic valve replacement, Tagliari et al [25] found an in-hospital mortality rate of 9.4% in the isolated aortic stenosis surgery group versus 20.9% in patients who underwent another surgical procedure. The main mortality predictors were ischemia time > 90 minutes, EF < 60%, and prior stroke.…”

IntroductionReplacement of the aortic valve in patients with a small aortic annulus is associated with increased morbidity and mortality. A prosthesis-patient mismatch is one of the main problems associated with failed valves in this patient population.ObjectiveTo evaluate the long-term mortality predictors in patients with a small aortic annulus undergoing aortic valve replacement with a bioprosthesis.MethodsIn this retrospective observational study, a total of 101 patients undergoing aortic valve replacement from January 2000 to December 2010 were studied. There were 81 (80.19%) women with a mean age of 52.81±18.4 years. Severe aortic stenosis was the main indication for surgery in 54 (53.4%) patients. Posterior annulus enlargement was performed in 16 (15.8%) patients. Overall, 54 (53.41%) patients underwent concomitant surgery: 28 (27.5%) underwent mitral valve replacement, and 13 (12.7%) underwent coronary artery bypass graft surgery.ResultsMean valve index was 0.82±0.08 cm2/m2. Overall, 17 (16.83%) patients had a valve index lower than 0.75 cm2/m2, without statistical significance for mortality (P=0.12). The overall 10-year survival rate was 83.17%. The rate for patients who underwent isolated aortic valve replacement was 91.3% and 73.1% (P=0.02) for patients who underwent concomitant surgery. In the univariate analysis, the main predictors of mortality were preoperative ejection fraction (P=0.02; HR 0.01) and EuroSCORE II results (P=0.00000042; HR 1.13). In the multivariate analysis, the main predictors of mortality were age (P=0.01, HR 1.04) and concomitant surgery (P=0.01, HR 5.04). Those relationships were statistically significant.ConclusionA valve index of < 0.75 cm2/m2 did not affect 10-year survival. However, concomitant surgery and age significantly affected mortality.

“…Percutaneous implantation of transcatheter prosthetic aortic valves without cardiopulmonary bypass (CPB) has continued to gain clinical acceptance for high-risk patients with aortic stenosis. Historically, the conventional open surgical replacement of a diseased aortic valve has been the gold standard, even in high-surgical-risk patients; however, these high-risk patents can experience severe comorbidities with a slight elevation in mortality with valve replacement [Brennan et al 2012;Tagliari et al 2012]. Fortunately, the development of a percutaneous approach without CPB for aortic valve replacement has offered a more ideal option for these high-risk patients [Kesavan et al 2011;Spargias et al 2013;Wilbring et al 2012].…”

“…Because the major cause of aortic stenosis (AS) is calcified degeneration of the aortic valve brought about by the aging process, the prevalence of aortic valve disease is higher in the elderly population, affecting approximately 5% of octogenarians. 1,2 The increased life expectancy has led to an increased need for surgical interventions on the aortic valve. 3 In 2011, the average lifespan of Japanese women was 85.9 years, and that of men was 79.4 years.…”
