A Case of Entrapped Rotablator Burr and Possible Mechanism of Entrapment: Insight from Intravascular Ultrasound Findings-Juniper Publishers
JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF CARDIOLOGY & CARDIOVASCULAR THERAPY Abstract The effectiveness of rotational atherectomy has been established for hard, calcified lesions rotablator burr entrapment is a rare complication of rotational atherectomy, estimated to occur in 0.4% of cases. A 54-year-old woman was admitted to our hospital to undergo percutaneous coronary intervention for an atherosclerotic lesion of left anterior descending coronary artery. Coronary angiography revealed diffuse narrowing with severe calcification in her left anterior descending coronary artery, which seemed to be refractory to conventional devices. We decided to perform lesion modification by rotablator. During rotablation, the burr suddenly stalled and became trapped at the distal portion of the left anterior descending coronary artery just beyond the severely calcified lesion. We successfully retrieved the entrapped burr by balloon inflation after the insertion of a second guide ...
