  • Title: Left ventricular approach to multiple ventricular septal defects.
    Author: Zavanella C, Matsuda H, Jara F, Subramanian S.
    Journal: Ann Thorac Surg; 1977 Dec; 24(6):537-43. PubMed ID: 596966.
    Abstract:
    Multiple muscular ventricular septal defects were closed through an apical left ventriculotomy in 11 patients. The patients were divided into two groups: Group 1, 8 patients who had transposition of the great arteries, and group 2, 3 patients without transposition. There were 4 deaths in Group 1 and non in Group 2. Two of the deaths were caused by a hypoplastic right ventricle, 1 by airway obstruction, and 1 by heart failure and pulmonary edema in a patient who had additional unrecognized muscular defects. An apical left ventriculotomy provides excellent exposure of the septum. The field is not obscured by trabecular bands or papillary muscles. Although 1 patient died because of residual VSDs, this approach, compared with previously described methods, minimizes the risk of unrecognized defects.
