Impact of Left Ventricular Systolic Function on Outcome of Correction of Chronic Severe Aortic Valve Regurgitation: Implications for Timing of Surgical Intervention

Preoperative LV dysfunction (EF <60%) had an adverse effect on overall survival after correction of chronic severe AR. Because survival is improved in patients with greater preoperative LVEF and because reverse LV remodeling is more complete with smaller LV dimensions, surgical intervention should be considered promptly in patients with chronic severe AR and deterioration of these indicators during echocardiographic surveillance.
