Intracoronary stent placement proximal to a myocardial bridge: immediate and long-term results

Catheter Cardiovasc Interv. 1999 Mar;46(3):363-7. doi: 10.1002/(SICI)1522-726X(199903)46:3<363::AID-CCD24>3.0.CO;2-V.

Abstract

The intracoronary stent placement in a lesion proximal to a myocardial bridge is of special importance and is considered to be a challenge for the interventional cardiologist. In this study 4 cases of stent implantation proximal to a coronary bridged segment are described. In all cases complications were observed after the procedure. The patients remained free of symptoms and the exercise TI201 test was negative for ischemia 8.5+/-2.6 months later. Although there is skepticism because of the abnormal coronary flow pattern, the endothelial dysfunction and the subsequent thrombogenicity, the stent placement proximal to a myocardial bridge was safe and with favorable long term results in all 4 cases. However, further studies in large populations are necessary.
