The presence and severity of coronary artery disease was measured using the Duke Myocardial Jeopardy Score (DMJS). A DMJS\u2009=\u20090 corresponds to patients without CAD or complete revascularization and a DMJS\u2009&gt;\u20090 to those with incomplete revascularization. LVEF recovery was assessed by transthoracic echocardiography, measuring the change in LVEF from baseline to 3\u2010months post\u2010TAVI.

At 3 months, patients with incomplete revascularization (DMJS\u2009&gt;\u20090) demonstrated less LVEF recovery post\u2010TAVI (2.0\u2009\u00b1\u20099.2% versus 11.7\u2009\u00b1\u20098.9% if DMJS\u2009=\u20090; <jats:italic>P<\/jats:italic>\u2009=\u20090.001). On multivariate analysis, DMJS and presence of significant delayed\u2010enhancement were found to be independent predictors of LVEF recovery.
