Bulboventricular foramen enlargement: an alternative surgical approach

Sachin Talwar et al. Indian J Thorac Cardiovasc Surg. 2019 Apr.

Abstract

Bulboventricular foramen (BVF) enlargement is often required to enlarge a restrictive interventricular communication in patients with univentricular hearts (UVH) to prevent the development of systemic ventricular outflow tract obstruction (SVOTO). We describe an alternative surgical technique through the transected pulmonary artery without an atriotomy, ventriculotomy or aortotomy that was successfully performed in a patient with double inlet left ventricle (DILV) with malposed great arteries (MPGA) and a restrictive BVF.

Keywords: Bulboventricular foramen; Single ventricle; Subaortic obstruction.
