[Coronary angioplasty in the acute phase of a myocardial infarction on a myocardial bridge].
A myocardial bridge is usually asymptomatic but can cause myocardial ischemia, myocardial infarction or sudden death. Two occurrences of coronary angioplasty in the acute phase of an anterior myocardial infarction on a myocardial bridge are reported. The first case was first treated only with a balloon, and then with a stent 12 h later after a relapse of angina pectoris and the recurrence of a severe compression. The second case immediately benefited from a stent. A systematic control at six months has shown the absence of restenosis in the first case and an asymptomatic occlusion of the stent in the second case. Its deocclusion has revealed a myocardial bridge downstream of the stent. Myocardial stunning might have caused a decreased systolic compression by the bridge in the first case, and an underestimation of its actual length in the second case. Its regression is held responsible for these two relapses. A long active stent installed at high pressure could be used to treat myocardial bridges during myocardial infarctions.
