Patients with aortic regurgitation and severe left ventricular dysfunction remain candidates for aortic valve replacement, as long as the risks of late left ventricular dysfunction and congestive heart failure have been fully discussed with the patient, the patient's family, and the referring physician. In contrast, patients with mitral regurgitation and severe systolic dysfunction are at considerable risk of more severe left ventricular dysfunction after operation, especially if mitral valve repair or chordal- sparing procedure cannot be performed. In patients who are candidates for such procedures that preserve the integrity of the subvalvular mitral apparatus, operation may be successful in selected patients despite moderate- to-severe depression of systolic function. Prognosis is guarded to prior in patients with regurgitant valvular lesions and advanced left ventricular dysfunction, and the emerging alternative treatments discussed in other articles in this Cardiology Clinics deserve consideration in these patients.
