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

The intracoronary stent placement in a lesion proximal to a myocardial brid ge is of special importance and is considered to be a challenge for the int erventional cardiologist, In this study 4 cases of stent implantation proxi mal 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 Tl-201 test was negative for ischemia 8.5 +/- 2.6 months l ater, Although there is skepticism because of the abnormal coronary flow pa ttern, 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 popula tions are necessary. (C) 1994 Wiley-Liss, Inc.
