title: Treatment of simple and complex coronary stenosis using rotational ablation followed by low pressure balloon angioplasty.
abstract: High speed coronary rotational ablation followed by adjunctive low pressure coronary balloon angioplasty was used in 166 patients. Complex lesions were present in 63% of patients. Clinical success was achieved in 157 patients (95%). Angiographic success rate was 10% in A lesions, 95% in B1 lesions, 98% in B2 lesions, and 93% in C lesions. Mean vessel lumen diameter has increased from 0.4 mm to 1.4 mm after rotational ablation and to 2.3 mm following adjunctive balloon angioplasty. Left ventricular dysfunction, the presence of total occlusion, and the severity of stenosis before the procedure were predictive of clinical failure. There were three abrupt vessel closures (1.8%) with one Q wave myocardial infarction. Non-Q wave myocardial infarction occurred in 14 patients (8.4%) and three patients died during hospitalisation (1.8%). We conclude that rotational atherectomy followed by adjunctive low pressure balloon angioplasty gives comparable high success rates in different coronary lesions.
