Methods ＆ Results This retrospective study sought to compare in-hospital and long-term outcomes for patients undergoing RA via the transradial （TR） and transfemoral （TF） route in 126 consecutive patients （59 radial, 67 femoral） from 2009 to 2014. TR RA procedures were performed in 44/62 （71%） by the three TR operators, compared with 15/64 （23%） by the four TF operators in the present study. Significantly smaller diameter guide catheters and burrs （1.39 ± 0.16 mm vs. 1.53 ± 0.24 mm, P = 0.001） were used in the TR group. Procedural success rates were similar in both TR and TF groups. There was a significantly less major access site bleeding complications in favor of radial artery access （2% vs. 16%, P = 0.012）. The incidence of in-hospital death or myocardial infarction was low in both groups. Although a trend of lower adverse event rate was demonstrated in the TR group compared with the TF one, no statistical significance （21% vs. 27%, P = 0.135） was detected. Conclusions Radial access, a useful alternative to femoral access for RA and DES, can be safely and successfully performed on up to 71% of the patients with heavily calcified coronary lesions needing RA by experienced TR operators.展开更多
