Abstract

We present Stanford's experience with patients post-arterial switch operation presenting with chest pain found to have hemodynamically significant myocardial bridging. The evaluation of symptomatic patients post-arterial switch should not only include assessment for coronary ostial patency but also for nonobstructive coronary conditions such as myocardial bridging. (Level of Difficulty: Advanced.).
