Safety and efficacy of rotational atherectomy in heavily calcified lesions involving coronary aneurysms

Abstract

Percutaneous transluminal rotational atherectomy (PTRA) is one of the most used techniques to facilitate percutaneous coronary intervention in heavily calcified coronary lesion (CCL). Coronary aneurysms (CAs) are detected in 1.2–4.9% of coronary angiogram. The presence of CA and CCL is infrequent but not rare, where the use of PTRA may be mandatory despite the high risk. After a complex procedure of PTRA in a CCL with CA we decided to investigate about this particular condition. We identified a total of six patients among 174 consecutive percutaneous coronary intervention (3.4%). All the procedures showed good stent expansion in the absence of major complications, such as no-reflow or coronary perforation. Cardiovascular death, rehospitalization for myocardial infarction and target lesion failure were not reported at follow-up (252 ± 152 days).
