Abstract
|
|
|
|
The left main coronary artery branches to form the left anterior descending and left circumflex arteries and supplies the entire myocardium of the left ventricle. Treatment guidelines recommend coronary artery bypass grafting in left main coronary artery disease. However, some recent studies have demonstrated that, although the target vessel revascularization rate is relatively high, percutaneous coronary intervention (PCI) has a comparable mortality rate to coronary artery bypass grafting in left main disease. In this case, an 80-year-old male with a recent ST elevation myocardial infarction of the right coronary artery (RCA) was transferred to our hospital for second-stage PCI for left main artery stenosis, which was found incidentally at the time of primary PCI of the RCA. Although he had severely depressed left ventricular function, a drug-eluting stent was implanted successfully in his left main coronary artery with percutaneous cardiopulmonary support.
