What is Batista surgery for dilated cardiomyopathy?
It is a surgical method to fix dilated cardiomyopathy. In idiopathic dilated cardiomyopathy, patients’ prognosis with medical treatment was poor, but there was no effective surgical treatment except for heart transplant until 1990s. In 1990s, however, Dr. Randas Batista from Brazil showed the effects of Batista surgery where lateral wall of the LV is excised and the LV becomes smaller, and since then, some patients with dilated cardiomyopathy became candidates of surgical treatment. Unfortunately Batista surgery (formally called partial left ventriculectomy, PLV) gave inhomogeneous and unpredictable results, and as a result, it became less popular. In USA, the Batista surgery is now almost abandoned. In Japan, Dr. Suma introduced and improved the surgery, and it became accepted in some centers, but not many. Q: What is modified Batista surgery?
