Abstract:
Objective To analyze the peri-procedural complications of coronary rotational atherectomy. Methods A total of 107 consecutive patients with coronary artery disease received rotational atherectomy from January 2012 to December 2016 were enrolled retrospectively. The occurrence rate and the management of peri-procedural complications were summarized. Results ① The serum level of CK-MB and cTnI in patients who received rotational atherectomy were signifi cantly elevated compared with the level before the procedure,[4.1(2.4-14.1)U/L vs.1.5(1.0-2.1)U/L,P<0.001]and[0.28(0.11-1.11)ng/ml vs.0.01 (0.01-0.02) ng/ml, P<0.001], respectively. Of the 107 target lesions, 104 (97.2%) were classifi ed as type B2 or C lesions.②Peri-procedural complications of coronary rotational atherectomy occurred in 21 patients (19.6%). There were 5 cases (4.7%) of coronary slow fl ow, 1 case (0.9%) of severe coronary spasm, 9 cases (8.4%) of coronary dissection after rotational atherectomy and 1 case (0.9%) of side branch occlusion. Six patients (5.6%) had severe sinus bradycardia, but only 1 patient required temporary pacemaker. Burr entrapment happened in 2 patients (1.9%). Peripheral vascular complications occurred in 2 patients (1.9%) with 1 case of femoral artery hematoma at puncture site and the other 1 case of mediastinal hematoma. One patient (0.9%) developed contrast induced nephropathy after the procedure. ③All the peri-procedural complications of rotational atherectomy were benign. The procedure instant success rate was 98.1%, with no acute or sub-acute stent thrombosis, cardiac death, emergent coronary artery bypass graft occurred during hospitalization. Conclusions The complications associated with coronary rotational atherectomy are not rare, but severe complications are not common. The procedure could be safely performed with a high instant success rate.
