Stent graft used to rescue coronary rupture during percutaneous coronary intervention for myocardial bridge.

Myocardial bridge (MB) is a congenital variation of the coronary arteries and the segment of the coronary artery through myocardium is compressed during systole. Although it is relatively asymptomatic, percutaneous coronary intervention (PCI) may be necessary to relieve symptoms. Perforation or frank rupture of coronary arteries occurs rarely in patients undergoing percutaneous coronary intervention. We report the coronary rupture in a case with myocardial bridge which occurred during percutaneous coronary intervention. We deployed a stent graft to successfully rescue the rupture of the distal segment of left anterior descending coronary artery (LAD-D) with myocardial bridge (MB).
