Spontaneous coronary dissection resulting in acute myocardial infarction: successful treatment with primary angioplasty.

Spontaneous coronary dissection is an unusual cause of acute myocardial infarction for which the optimal therapy has not been established. We report the case of a 63-year-old man with acute lateral wall myocardial infarction resulting from spontaneous dissection of the major diagonal branch of the left anterior descending artery in whom acute and long-term patency was restored by primary PTCA.
