Abstract

Background: Percutaneous interventions for aorto-ostial narrowing of native coronary arteries are challenging because of early elastic recoil after the procedure and the high restenosis rate. Cutting balloon angioplasty may reduce this complication.

Hypothesis: The purpose of the study was to evaluate the clinical outcomes of cutting balloon angioplasty and stent implantation for aorto-ostial lesions with a 1-year clinical follow-up.

Methods: All patients with aorto-ostial lesions in our laboratory underwent cutting balloon angioplasty and were followed for approximately 1 year.

Results: Forty-eight patients underwent balloon angioplasty; 36 of whom had lesions in the ostial right coronary artery, and 12 of whom had lesions in the left main coronary artery (LMCA). Thirty-five patients (73%) had a stent implanted. Procedural success was achieved in all patients. The in-hospital rate of major adverse cardiac events (MACEs) was 2.1% because of the death of 1 patient following urgent bypass surgery. Mean clinical follow-up was 11.6 +/- 7 month. Twelve patients (27%) required repeat coronary angiography, and restenosis was found in 7 patients (16%). Six patients (13.6%) had MACEs.

Conclusions: Cutting balloon angioplasty in combination with bare metal stent (BMS) implantation has a good clinical outcome. This technique should be compared with implantation of drug-eluting stents (DESs) in a controlled study.
