Cutting balloon angioplasty and stent implantation for aorto-ostial lesions: clinical outcome and 1-year follow-up.
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.


OBJECTIVE
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.
