[Therapy of refractory ventricular tachycardia in congenital diverticulum of the left ventricle. Clinical aspects and surgical therapy of a rare malformation].
True congenital diverticulum of the left ventricle is an extremely rare lesion, usually associated with defects of the pericardium and the diaphragm. It is defined as a finger-like extension of the ventricular chamber with its wall consisting of all three layers of a normal heart-wall and with the ability to contract properly. Additional cardiac malformations may lead or contribute to early death; if not, the patients die from rupture of the diverticulum. To our knowledge the isolated form without pericardial defect has been reported only once before. The findings are described in an adult who presented with ventricular tachycardia at the age of 43 years. Complete normalization was achieved by resection of the diverticulum with the aid of cardiopulmonary bypass. The literature is reviewed for comparable cases. Etiological considerations are presented and the clinical features are discussed.
