    Abstract:
    The Batista operation is intended to improve cardiac function by reducing the diameter of the left ventricle by excising of a sizable amount of the left ventricular free wall. Candidates for this operation are patients awaiting cardiac transplantation due to end-stage dilated cardiomyopathy and those unsuitable for transplantation because of age, physical or economical reasons. We performed this operation in 10 patients between December 1996 and October 1997. The baseline indication is left ventricular diastolic dimension > or = 70 mm and New York Heart Association (NYHA) class III or IV. There were eight men and two women aged from 16 to 60 years (mean 46 years). All had non-ischemic cardiomyopathy including seven idiopathic and one each of hypertrophic, arrhythmogenic right ventricular and valvular (sarcoidosis) cardiomyopathy. Eight patients were in NYHA class IV and six needed inotropic drip therapy prior to the operation. Nine patients had significant mitral regurgitation and six had tricuspid insufficiency concomitantly. Eight patients underwent mitral valve replacement and one was treated with mitral valve plasty. Six patients also had tricuspid plasty combined with partial left ventriculectomy. Eight patients survived. Mean value of left ventricular end-diastolic diameter was reduced from 77.8 mm to 59.8 mm, left ventricular end-diastolic volume index was reduced from 189.3 to 99.2 ml/m2, ejection fraction was increased from 19.0% to 33.8% and NYHA class improved from 3.8 to 1.8. Six months later, left ventricular dilatation was not noticed in four patients examined. The Batista operation offers real hope for patients with end-stage dilated cardiomyopathy, but we still have much to learn.
