[Coronary angiography by transradial approach with 5F universal catheter].
OBJECTIVE
To probe the efficacy and feasibility of the transradial approach for diagnostic coronary angiography with 5F universal catheter.


METHODS
Transradial coronary angiography was performed in 3094 consecutive patients, 2396 men and 698 women, aged 30 - 81 years, mean age (56.1 +/- 9.8) years, from July 2000 to April 2004. Patients were divided into 5F improved Terumo catheter group (improved Terumo group, n = 985), 5F universal Terumo catheter group (Terumo group, n = 1024) and 5F universal Medtronic catheter group (Medtronic group, n = 1085). The procedure success rate, duration of operation and fluoroscopy between groups were compared.


RESULTS
The procedure success rate was 98.4% in improved Terumo group, 98.0% in Terumo group, and 96.0 % in Medtronic group, respectively. The success rate was higher in improved Terumo group than in Medtronic group (P < 0.05). The average duration of operation and fluoroscopy in improved Terumo group was (17.9 +/- 5.8) min and (4.8 +/- 1.8) min, in Terumo group was (18.2 +/- 5.5) min and (5.0 +/- 1.7) min, but (21.1 +/- 7.2) min and (5.2 +/- 1.9) min in Medtronic group. There were significant differences among group (P < 0.05).


CONCLUSIONS
(1) Transradial coronary angiography with small diameter universal catheter is safe and easy to perform with a higher success rate and allow earlier patient ambulation, and should be strongly encouraged and recommended. (2) Option of angiographic catheter plays a key role in the safety, efficacy and quality of transradial coronary angiography. Seemingly, the improved Terumo group was excellent and shoud be popularized.
