Left Ventricular Volume Reduction Surgery in the Middle East

Abstract

Heart transplantation is not yet socially acceptable in the Middle East, and left ventricular assist facilities are not generally available in this region. Therefore, left ventricular volume reduction surgery was attempted in 41 patients with end-stage heart failure (33 males; median age, 36.3 years) in 4 Middle Eastern tertiary referral centers between February 1996 and January 2001. Heart failure was due to idiopathic cardiomyopathy in 21 patients, ischemia in 11, rheumatic valvular disease in 8, and viral myocarditis in 1. Associated procedures were aortic valve replacement in 5 patients, mitral valve repair in 25, mitral valve replacement in 7, tricuspid valve repair in 6, and coronary bypass grafting in 8. Hospital mortality was 31.7%. Five patients were lost to follow-up. The survival rate of hospital survivors at 18 months was 65.2%. Three of the surviving patients did not benefit from the operation. Although our results were somewhat disappointing, this operation remains an option for surgeons working in developing areas of the world. It is hoped that better patient selection and new techniques of left ventricular volume reduction that avoid resection of viable muscle will further improve the outcome of this operation.
