Catheter tip erosion due to rotablator burr: an unusual complication

We report the case of an 80-year-old woman having recently undergone non-ST elevation myocardial infarction revealing diffusely hypokinetic dilated cardiomyopathy with LVEF of 30%. Coronary angiogram showed a multi vessel coronary artery disease with heavily calcified atherosclerotic lesions. We found a stenotic proximal left anterior descending (LAD) coronary artery and a sub occluded proximal left circumflex artery branching out into a large obtuse marginal artery (video A & B). However, the most severe lesion was the critically stenotic ostium of a severely calcified right coronary artery (RCA) followed by a calcified stenosis of its medium segment (video C).
