A 70-year-old woman was referred to us with postinfarction angina. During c
ardiac catheterization the only coronary abnormality found was myocardial b
ridging in the mid and distal parts of the left anterior descending coronar
y artery, despite a large ventricular septal rupture. The pulmonary-to-syst
emic flow ratio was 2.5:1. Her operation was successful. (C) 2001 by The So
