PG - 204-212 LID - 10.1159/000490848 [doi] AB - BACKGROUND: Noninvasive measurement of myocardial contractility (end-systolic wall stress-adjusted change in left ventricular ejection fraction from rest to exercise [DeltaLVEF - DeltaESS]) predicts heart failure, subnormal LVEFrest, and sudden death in asymptomatic patients with chronic severe aortic regurgitation (AR). Here we assess the relation of preoperative DeltaLVEF - DeltaESS to survival after aortic valve replacement (AVR). METHODS: Patients who underwent AVR for chronic, isolated, pure severe AR (n = 66) were followed for 13.0 +/- 6.4 event-free years. Preoperative DeltaLVEF - DeltaESS (from combined echocardiographic and radionuclide cineangiographic data) enabled cohort stratification into 3 terciles (-1 to -11% [normal or mild] contractility deficit, -12 to -16% [moderate], and
