[Analysis of coronary rotational atherectomy related complications].
To analysis the complications of coronary rotational atherectomy and evaluate the safety of this procedure.A total of 250 rotational atherectomy cases from April 1994 to February 2012 were screened retrospectively and 22 cases patients (8.8%) with rotational atherectomy-related complications were included in this analysis.Among these 22 patients, all lesions were either type B2 or C calcified lesions as evidenced by coronary angiography. After the rotation procedure, there were seven cases (2.8%) with slow reflow and two (0.8%) cases with no reflow. Seven cases (2.8%) developed severe coronary spasm and two cases (0.8%) had sinus bradycardia. Coronary dissection occurred in two cases (0.8%), while one case (0.4%) had coronary perforation and cardiac tamponade. Burr entrapment happened in one case (0.4%). There was no malignant arrhythmia, acute myocardial infarction, emergent coronary artery bypass graft or device related death during and post procedure. Comparison with baseline data, the concentration of CK-MB elevated significantly after the rotational atherectomy [(31.2 ± 4.8) mmol/L vs. (11.4 ± 6.5) mmol/L, P < 0.05].Coronary rotational atherectomy is safe and procedure-related complications are rare.
