متن کاملLow-gradient aortic stenosis
Low-gradient aortic stenosis (AS) has been a vexing problem for cardiologists since its original description in 1980 by Carabello et al.1 In that study, 3 of 4 patients with low-gradient AS died at surgery, and the other patient had persistent severe heart failure postoperatively. Subsequent studies showed that although operative mortality is high, most patients survive aortic valve replacement...
متن کاملTranscatheter Aortic Valve Replacement: A Review Article
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
متن کاملRecent advances in aortic valve replacement for aortic stenosis
Aortic valve replacement is no longer an operation that is approached solely through a median sternotomy. Recent advances in the fields of transcatheter valves have expanded the proportion of patients eligible for intervention. Comparisons between transcatheter valves and conventional surgery have shown non-inferiority of transcatheter valve implants in patients with a high or intermediate pre-...
متن کاملTiming of valve replacement for aortic stenosis.
V alve replacement for aortic stenosis is easily recognized as life saving, because of the short survival of most patients with advanced symptomatic stages of aortic stenosis. However, there is an increased late mortality from congestive heart failure occurring years after the aortic valve replacement. This problem has been thought to relate to irreversible myocardial changes, manifested morpho...
