A case of an entrapped rotational atherectomy burr.
نویسندگان
چکیده
Rotational atherectomy is a widely used modality in percutaneous coronary revascularization, especially for heavily calcified coronary arteries [1–5]. Due to the unique mechanism of rotational atherectomy, there have been reports of unusual complications, including fracture of coronary wire, guidewire bias, coronary spasm leading to myocardial infarction, and fracture of the drive shaft causing acute ischemia [6–9]. We provide the first case reported of entrapment of an atherectomy burr in the left anterior descending artery (LAD) and a technique for its removal.

A Case of Entrapped Rotablator Burr and Possible Mechanism of Entrapment: Insight from Intravascular Ultrasound Findings
The effectiveness of rotational atherectomy as the primary strategy for complex, severe calcified lesions has been established for facilitating device delivery, optimal stent expansion, and good apposition [1-6]. However, the rotablator carries the potential for life-threatening complications. Flow complications, including slow flow/no reflow, coronary perforation, and dissection, are well know...
متن کاملPercutaneous retrieval of a detached rotational atherectomy burr
Rotablation (rotational atherectomy) is an acknowledged method of percutaneous treatment of highly calcified coronary artery lesions that cannot be treated with traditional angioplasty. The complexity of the technique and usage of very specific equipment can contribute to the development of uncommon complications. We present a case of percutaneous retrieval of a damaged rotational atherectomy b...
متن کاملNovel Use of the GuideLiner Catheter to Deliver Rotational Atherectomy Burrs in Tortuous Vessels
Rotational atherectomy (RA) for heavily calcified lesions is essential for improved stent delivery and stent expansion. In tortuous vessels it is often difficult to advance the burr without rotation and possible injury to the endothelium of healthy vessel. The GuideLiner catheter, a child in mother catheter, has recently been used to allow for increased support for delivery of stents through to...
متن کاملMechanism and management of burr entrapment: A nightmare of interventional cardiologists
Entrapment of the burr within calcified lesion is an uncommon, but serious complication during rotational atherectomy and usually needs surgical retrieval. We report a case series of this complication and also review the possible mechanisms, such as kokesi phenomenon or insufficient pecking motion with decreased rotational speed. We also review the potential techniques ever proposed to rescue t...

BACKGROUND High-speed rotational atherectomy uses a diamond-coated, elliptical burr to abrade occlusive atherosclerosis, especially noncompliant calcified plaque. METHODS AND RESULTS Intravascular ultrasound (IVUS) was used to analyze 28 patients after atherectomy. Arteries treated and imaged were left main (three), left anterior descending (12), left circumflex (five), right coronary (seven)...
