Objectives

Narrative objectives1

The aim of this study was to evauate the correlation between the real ablation area and predited ablation area based on optical frequency domain imaging (OFDI) to the patients with severe coronary artery calcification lesions who used Rotational atherectomy during percutaneous coronary angioplasty.

Assessment

Primary outcomes

Calculation of prediction accuracy (correct and error rate) of Rotational atherectomy based on OFDI images

Key secondary outcomes

1. Percentage of adverse event occurrence (coronary artery perforation, coronary dissection, peri-procedural myocardial infarction, slow-flow / no-reflow phenomenon, rota burr entrapment)
2. Investigation of factors related to prediction accuracy
