1-Year Survival After TAVR of Patients With Low-Flow, Low-Gradient and High-Gradient Aortic Valve Stenosis in Matched Study Populations

摘要

OBJECTIVES This study sought to examine whether the prognosis of patients with severe aortic stenosis (AS) having high versus low transvalvular mean pressure gradients (MPGs) is intrinsically different after transcatheter aortic valve replacement (TAVR), even after strict matching of baseline parameters.
