Background Aortic regurgitation (AR) is a common valvular lesion associated with increased mortality once the left ventricle enlarges significantly or develops systolic dysfunction (ejection fraction Methods A total of 1,100 consecutive patients with chronic moderate to severe and severe AR on echocardiography between 2004 and 2019 were retrospectively analyzed. The modified Simpson disk summation method was used for LV volume estimation. The primary outcome was all-cause mortality; the secondar...

Abstract Background Bicuspid aortic valve(BAV) is common. Some studies suggest that all BAV patients require screening for intracranial aneurysm(IA) in order to prevent sub-arachnoid hemorrhage(SAH). Aortic coarctation(CoA) carries high-risk of both IA and SAH. Using a nationally-representative population, we assessed the frequency of IA and SAH in admissions with BAV-without-CoA versus admissions with CoA(with or without BAV). Methods Between 2000 and 2016, adult admissions with a primary/secon...

Patients with bicuspid aortic valve (BAV) develop aortic regurgitation (AR) at younger age. Hemodynamically significant AR(≥moderate-severe) is associated with excess death. However, predictors and rate of progression from ≤moderate AR to ≥moderate-severe AR in BAV remain unknown. Our study

Abstract Objective To study contemporary etiologies, mechanisms, and corresponding surgical approaches in isolated aortic regurgitation (AR). Patients and Methods Consecutive patients undergoing surgery for moderately severe and severe AR were retrospectively identified from January 1, 2006, through October 20, 2017. Intraoperative echocardiograms, surgical reports, and pathology reports were reviewed. Results Of 382 patients (54±16 years, 82% men), there were 207 (54%) tricuspid (TAV), 167 (44%...
