[Spontaneous dissection of the coronary arteries: a rare cardiologic diagnosis].

A 55-year-old woman who was admitted to hospital with acute chest pain as a case of emergency suffered from an acute anteroseptal myocardial infarction. Four weeks later coronary angiography revealed a long dissection of the left anterior descending artery (LAD) as well as a significant stenosis of the left main and the proximal circumflex. Cardiovascular surgery was done subsequently. In addition to myocardial revascularization using coronary artery bypass grafts a readaptation of the dissecting artery walls and a proximal ligation of the LAD before anastomosis were performed. Clinical data, pathogenesis, and indications for medical and surgical treatment of spontaneous artery dissection are presented.
