Indexed Left Ventricular Dimensions Best Predict Survival After Aortic Valve Replacement in Patients With Aortic Valve Regurgitation

In patients who received a valve replacement for aortic regurgitation, decreased ejection fraction and increased left ventricular dimensions were not associated with late mortality. However, larger indexed left ventricular systolic and diastolic dimensions were associated with late mortality. Preservation of late ejection fraction is best if the operation is performed in patients with near normal preoperative left ventricular function.
