  • Look Inside

A 72-year-old woman with a history of transient cerebral ischemic attack was reported. She was diagnosed as having mitral stenosis with atrial fibrilla-tion but angiographically normal coronary arteries in 1988. Since then, she has had anticoagulant therapy to control symptoms. In February 1994, complaining of chest pain, she was diagnosed on ECG as having acute inferior myocardial infarction. Emergency coronary angiography 4 hours after onset showed total occlusion suggesting thromboembolism at the distal portion of the right coronary artery (#4AV). Intracoronary throm-bolysis using t-PA was performed immediately, but recanalization was not successful. The angiogram after 17 days revealed no stenosis at this occluded portion. Acute myocardial infarction associated with mitral stenosis despite the performance of intracoronary thrombolysis has been reported in seven cases including this case. In the acute phase, thrombolysis alone could not bring about recanalization, but in the chronic stage stenosis was not present. Moreover, in most of the cases, the obstructive portion of the coronary artery was distal and its perfusive myocardium was small. Our case suggested that acute myocardial infarction with mitral stenosis should be treated by conventional therapy rather than by thrombolysis.
