Rescue coronary angioplasty in a patient with acute myocardial infarction and myocardial bridge

Rescue Coronary Angioplasty in a Patient with Acute Myocardial Infarction and Myocardial Bridge Case ReportMyocardial bridge ( MB) is an infrequent angiographic finding, with an incidence ranging from 0.5% to 2.5% 1 .At autopsy, however, it has ranged from 15% to 85% 2,3 .Most patients with MB are asymptomatic but, when symptoms are present, patients may have angina 4 , AMI 1,5,6 , and even sudden death 7 .The exact mechanism through which MB induces myocardial ischemia is currently unknown, making the identification and therapy of this condition more difficult.Medical management has included aspirin, calcium antagonists, and beta-blockers, although the efficacy of these drugs in preventing ischemic complications has not yet been proved 1,8 .Reports of coronary intervention with ballooncatheter and stent in patients with MB and angina or AMI have been described in the literature 1,9,10 .In this report, we a describe successful rescue coronary angioplasty in a patient who failed to respond to thrombolytic therapy.We have not found any similar reports in the literature.
