First-phase ejection fraction by cardiovascular magnetic resonance predicts outcomes in aortic stenosis

First-phase ejection fraction (EF1; the ejection fraction measured during active systole up to the time of maximal aortic flow) measured by transthoracic echocardiography (TTE) is a powerful predictor of outco...
