DOIAbstract
ObjectivesWe evaluated a large multicenter series of patients operated on for low-flow/low-gradient aortic stenosis (LF/LGAS) to stratify the operative risk, assess whether perioperative mortality has decreased over recent years, and analyze the post-operative outcome.BackgroundAlthough LF/LGAS is classically associated with a high operative risk, few data are available concerning the results of surgery in this setting.MethodsA total of 217 consecutive patients (168 men, 77%) with severe aortic stenosis (area <1 cm2), low ejection fraction (EF) (≤35%), and low mean gradient (MG) (≤30 mm Hg) who underwent aortic valve replacement (AVR) between 1990 and 2005 were included.ResultsPerioperative mortality was 16% and decreased dramatically from ...
