Isolated Interventricular Septal Defect Due to Nonpenetrating Trauma

Abstract
A large ventricular septal defect acquired by blunt trauma to the chest spontaneously diminished in size and closed almost completely, as documented by serial cardiac catheterizations. The pulmonary-systemic flow ratio decreased from 3.6:1.0 to 1.2:1.0. The patient was asymptomatic eight years after the septal perforation.
