Percutaneous Coronary Intervention in Unprotected Left Main Coronary Artery Disease

Percutaneous coronary intervention for unprotected left main coronary artery disease is potentially an important intervention in surgically unstable patients. A detailed review of medical record and visual analysis of coronary angiography and PCI procedure was undertaken. The study was conducted at the Aga Khan University Hospital, from January 2003 to December 2007. Patients included in the study had unprotected > 70% left main stenosis with ongoing ischemia, considered unsuitable for surgical revascularization. A total of 9 patients were included with a mean age of 70.1 years. Six patients had cardiogenic shock. Eight patients had bifurcation lesion. Simultaneous kissing stenting technique was used in 4 patients. There were 4 in-hospital deaths while 5 patients were alive at discharge. All 4 patients who expired had cardiogenic shock. Four patients were alive at a mean follow-up of 17 months. PCI turned out to be an alternative therapeutic option for unprotected left main coronary artery disease when surgery is declined.
