Aortic Valve Gradient and Clinical Outcome in Patients Undergoing Transcatheter Aortic Valve Implantation for Severe Aortic Stenosis.

abstract：OBJECTIVE:The aim of this study was to determine the feasibility, reproducibility, safety and information obtained on exercise physiology from cardiopulmonary exercise testing (CPX) in patients with aortic stenosis. METHODS:Patients with an aortic valve area (AVA) <1.3 cm2 who were judged asymptomatic or equivocal sym...
