Long Term Follow-Up After Aortic Valve Replacement (Ross Procedure): Echocardiographic Determinants of Ventricular Recovery

Abstract

Aims and Methods: This prospective cohort study aimed to assess LV recovery post aortic valve replacement, stratified according to pre-operative valve lesion (aortic stenosis (AS), mixed disease (AS/AR) or aortic regurgitation (AR)), as well as define predictors of persistent LV dilatation post operation. We prospectively followed all patients post Ross procedure performed between 1992 and 2009 by a single surgeon. Echocardiography was performed pre-operatively, at approximately one year post operation then second yearly thereafter. Results: 265 patients were followed for a mean of 6.4 years (range 1-14 years, total 1702 patient-years). Seventy percent were male and mean age was 38.8±12.6 ye..
