To investigate the safety and efficacy of rotational atherectomy (RA) in the treatment of heavily calcified coronary lesions via the transradial approach.
This retrospective study sought to compare patients undergoing RA via the transradial (TR) and transfemoral (TF) route in 72 consecutive patients with severely calcified lesions (37 radial, 35 femoral) in our hospital from September 2012 to September 2015. The primary outcomes included acute myocardial infarction(AMI), revascularization and death.
Procedural success rates were 100% in both TR and TF groups without complications. There was a significantly less major access site bleeding complications in favor of radial artery access(8.1% vs 28.6%, P=0.009). RA procedural complications rates were similar in two groups (17.1% vs 24.3%, P=0.675, the duration in bed and mean hospital stay of the TR group was both shorter than that of TF group (9.1±18.0 vs 38.4±25.8 hours, P<0.001; 5.3 ± 1.7 vs 7.7 ± 3.1 days, P<0.001), both the incidence of in-hospital and one year follow-up major adverse cardiac events (MACE) were low in TR and TF group (13.5% vs 17.1%,P=0.156; 16.2% vs 11.4%, P=0.516).
Radial access can be safely and successfully used as an alternative to femoral access for RA performance on the patients with heavily calcified coronary lesions needing RA by experienced operators.
