High-Frequency Rotational Angioplasty

1991

In 19 patients with significant coronary artery disease, PTCR was used instead of PTCA. The PTCR was successful in all patients, but in nine patients additional PTCA was successfully performed. Coronary luminal narrowing could be reduced from 78 ± 19% to 32 ± 14% after rotablation and by combined treatment to 21 ± 14%. Only in one patient did coronary dissection occur; the patient was sent to surgery and had an uneventful outcome. No vessel perforation was observed. In one patient peripheral diagonal branch occlusion occurred. All vessels were open according to 24-control coronary angiography. Restenosis (>70% stenosis) occurred in 4/15 patients controlled after 6 months, mainly in those wi…
