Long-term outcome of patients with moderate and severe prosthetic aortic valve regurgitation after transcatheter aortic valve implantation.

Recently, moderate and severe postprocedure aortic regurgitations (ARs) have been identified as independent risk factors for short- and midterm mortality after transcatheter aortic valve implantation (TAVI). However, very few data exist on the long-term outcome of postprocedure AR. From 2008 to 2011, 198 consecutive patients with severe aortic stenosis successfully underwent TAVI with the CoreValve prosthesis (Medtronic CV, Minneapolis, Minnesota).

Heart failure in severe aortic valve stenosis: prognostic impact of left ventricular ejection fraction and mean gradient on outcome after transcatheter aortic valve implantation.

Aims: This prospective study aimed to evaluate the prognostic impact of left ventricular ejection fraction (LVEF) and aortic mean gradient patterns on outcome after transcatheter aortic valve implantation (TAVI).

Methods And Results: From 2008 to 2011, 202 consecutive patients with severe symptomatic aortic valve stenosis (aortic valve area <1.0 cm(2)) were submitted to TAVI.
