Percutaneous coronary intervention of osteal lesions in newly established tertiary care cardiac hospital

To assess the outcome of percutanious Angioplasty in patients with osteal lesions in Coronary artery Diseases. This is a retrospective analysis of all coronary angiograms performed at the catheterization laboratory of Karachi Institute of Heart Diseases (KIHD), a tertiary referral center in Karachi, Pakistan, between the periods August 2006 to August 2008. Fifty patients were enrolled which included thirty-five men and fifteen women and all were >40 years of age. Each patient had a single target osteal lesion: twenty nine patients underwent PCI for ostial LAD lesion (among them twenty males and nine females), six had ostial LCX (five males and one female), and fifteen patients had osteal RCA stenosis (10-male patients and 5- female patients). After high-pressure balloon dilatation residual stenosis was reduced. Twelve patients were treated with bare metal stents (BMS) while thirty eight with drug eluting stents (DES). In all cases the procedure was successful without any pre and post procedural complications. A key issue in the treatment of an osteal lesion is to assure that the stent is inserted proximal enough to fully cover the osteal junction. Improvements in technique, equipment, adjunctive drug therapy and better understanding of the procedure have remarkably changed the practice of interventional cardiology. (author)
