[Does rotablation of complex coronary artery stenosis lower the risk of subsequent PTCA?].
To answer the question of whether pretreatment of complex coronary artery lesions via rotablation reduces the risk of subsequent PTCA, we compared the results of PTCA of 250 patients with Typ B- and C-lesions treated between April 1 and November 11 1991 (Group A) with a group of 437 patients treated between January 1 and May 1 1992 (Group B), for whom not only PTCA but also rotablation was available. Rotablation was successful in 102 of 119 procedures (85.7%), the rate of major complications was 1.8%. The primary success rate for treatment of all complex lesions was higher in group B (87.3%) in which 22.2% of the lesions were treated with the rotablator than in group A (83.1%). Dissection rate was similar in both groups (18.5% in group A, 17.5% in group B). In group B patients, however, dissections could be controlled more frequently by the use of a reperfusion catheter (21% vs 8.3% in group A). Serious complications caused by a dissection were not so often observed. In group B patients the rate of major complications due to dissection was lower (2.5% vs 4.4% in group A). In summary, pretreatment of complex coronary artery lesions via rotablation seems to increase the success rate of the following PTCA and to reduce its risks.
