What is the comparison of percutaneous versus surgical revascularization of severe unprotected left main coronary stenosis in matched patients?
A 2008 study by Ellis et al. compared percutaneous versus surgical revascularization of severe unprotected left main coronary stenosis in matched patients. The study found that percutaneous revascularization resulted in lower mortality rate, lower major adverse cardiac event rate, and lower repeat revascularization rate than surgical revascularization. Moreover, the study found that patients with percutaneous revascularization had better left ventricular ejection fraction and lower incidence of stroke and myocardial infarction at 30 days after the procedure. However, there was no significant difference in terms of major adverse cardiac event rate at 5 years between the two groups.
