Abstract

Objective There are limited data on transcatheter aortic valve insertion after previous mitral valve operation. To better understand the associated procedural risks, we reviewed our single-center experience. Methods We retrospectively reviewed the records of 772 consecutive patients who received transcatheter aortic valve insertion from November 2008 through August 2016. There were 18 (2%) patients who had previous mitral valve operation that included valve repair in 4 patients (22%) and replacement in 14 (78%). Results Baseline characteristics included age of 77 years (interquartile range 68, 84), female sex in 11 patients (61%), New York Heart Association functional class III/IV in 14 (78%), and Society of Thoracic Surgeons predicted risk of mortality of 7.0% (5.3, 12.0). Access was transfemoral in 14 patients (78%). Valve insertion was successful in all patients and involved a balloon expandable device in 10 (56%). No patient experienced acute mitral valve dysfunction or procedure-related mortality. Follow-up echocardiography demonstrated mean systolic aortic valve gradient of 9 mm Hg (8, 12), no grade moderate or greater aortic paravalvular regurgitation, and stable mitral valve function. Kaplan-Meier estimated survival was 90.9% ± 9.1% at 1 year. Conclusions Transcatheter aortic valve insertion appears to be a safe and effective operation after previous mitral valve operation. Procedure success was achieved with both balloon expandable and self-expanding devices and was independent of arterial access method. Transcatheter valve insertion should not be denied strictly on the basis of a previous mitral valve operation.
