Batista procedure

The Batista procedure, also known as a Batista operation or partial left ventriculetcomy (PLV),[1] was an experimental heart procedure that proposed the reversal of the effects of remodeling in cases of end-stage dilated cardiomyopathy refractory to conventional medical therapy. The operation involves removing a slice of living tissue from an enlarged heart, then stitching together the beating heart, to allow the left ventricle to contract more efficiently.[2] In spite of promising initial results, the method was soon found to be of little if any benefit, and it is no longer considered a recommended treatment for the disease.

The Batista procedure was invented by Brazilian physician and cardiac surgeon Randas Batista in 1994 for use in patients with non-ischemic dilated cardiomyopathy. Many of his patients were victims of Chagas disease. Chagas disease represents a parasitic nonischemic cardiomyopathy targeting parasympathetic inflow to the heart. Chagas cardiomyopathy thus represents a unique method of study of diastolic heart failure. It may be addressed by removal of a portion of viable tissue from the left ventricle to reduce its size (partial left ventriculectomy), with or without repair or replacement of the mitral valve.[3]

Although several studies showed benefits from this surgery, studies at the Cleveland Clinic concluded that this procedure was associated with a high early and late failure rate. At 3 years only 26 percent were event-free and survival rate was only 60 percent.[4] Most hospitals in the US have abandoned this operation and it is no longer included in heart failure guidelines.[5][6]
