Patency of the Radial Artery Clinical Trial
Official title:
Novel Angioplasty USIng Coronary Accessor
To investigate the advantage of using a 4Fr guiding catheter over a 6 Fr, frequencies of radial artery occlusion after transradial coronary intervention (TRI) will be evaluated. Radial artery occlusion rate in 4 Fr TRI group is expected to be not more than that in 6Fr groups.
Prerequisites for TRI were a sufficiently pulsating radial artery and presence of an ulnar
pulse with a sufficient palmar arch, as evidenced by the absence of digital ischemia
according to the Allen's test. Exclusion criteria for the current study included planned use
of a cutting balloon, rotational atherectomy, directional coronary atherectomy, and
intravascular ultrasound, which were not compatible with 4-Fr catheter.
Patency of the radial artery after TRI will be evaluated by pulsation of the radial artery,
and frequencies of which will be compared between those receiving 4Fr vs 6 Fr coronary
interventions.
