Novel Angioplasty Using Coronary Accessor

Not Applicable
Completed
Conditions
Patency of the Radial Artery
Interventions
Procedure: PCI (percutaneous coronary intervention)
Registration Number
NCT00815997
Lead Sponsor
NAUSICA Investigators
Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
Number of Patients With Radial Artery Occlusionwithin 2 days after TRI

The primary endpoint was radial artery occlusion the day after TRI, defined as the absence of a radial pulse confirmed by a reverse Allen's test.

Secondary Outcome Measures
NameTimeMethod
Number of Patients With Successful PCIwithin 2 days after TRI

Procedural success was defined as a postprocedural residual stenosis of less than 20%, and a thrombolysis in myocardial infarction (TIMI) grade 3 angiographic flow without MACE during in-hospital follow-up.

Number of Patients With Access-site Complicationswithin 2 days after TRI

Access-site-related complications were defined as bleeding, pseudoaneurysm, arteriovenous fistula, and occlusion of the radial artery, which were considered to be major if they were associated with a vascular repair or a blood transfusion.

Number of Patients With Measure Adverse Cardiac Event (MACE)within 2 days after TRI

Defined as a composite of cardiac death, myocardial infarction, and target lesion revascularization
