The Batista procedure: Fact, fiction and its role in the management of heart failure

End-stage heart failure is associated with high rates of mortality. Obviously, heart transplantation is the ultimate surgical intervention for its treatment. However, this surgical option is severely limited by immunosuppressive drug morbidity and inadequate donor organ availability. Partial left ventriculectomy, the so called Batista procedure, has been proposed for the treatment of dilated cardiomyopathy and other end-stage heart failure. Although initial reports lacked significant information on the safety and efficacy of this procedure, overall clinical impression from the reports is that the operation may serve as a relatively inexpensive bridge to transplantation especially in the patients with idiopathic dilated cardiomyopathy. In order to select an exact procedure to resect appropriate amount of scar tissue, dobutamine echocardiographic study, intraoperative volume reduction test using cardiopulmonary bypass, positron emission tomography, or magnetic resonance imaging scans can be used. To avoid the late deterioration related to the development of significant mitral valve regurgitation, definitive mitral valve repair or replacement at the time of the partial left ventriculectomy may be advised. Further study is required to determine the procedure's exact role in the treatment of congestive heart failure. This would have to be a multicenter, randomized, and long-term follow-up study.
