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.

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.

A novel ultra-thin bare metal stent (BMS): results from a worldwide registry.

Aims: To evaluate a new generation, thin strut, stainless steel Tsunami coronary stent in a contemporary percutaneous coronary intervention (PCI) practice across a wide geographical area.

Methods And Results: Patients (n=1,437) with single or multiple vessel coronary artery disease undergoing PCI in 82 sites in Europe, Asia, and Australia were enrolled in the MATSURI registry. Clinical follow-ups were scheduled at 1, 6 and 18 months.
