Randomised comparison of JUDkins vs. tiGEr catheter in coronary angiography via the right radial artery: the JUDGE study

Abstract

The Tiger-II was found superior to the Judkins 3.5L/4R regarding contrast volume use, procedural and fluoroscopy time, spasm rate and RCA imaging, and inferior regarding LAD and LCX imaging.

Procedural and clinical performance of dual‐ versus single‐catheter strategy for transradial coronary angiography: A meta‐analysis of randomized trials

“…,000 IU in all trials. In four trials, 5,8,14,15 the primary endpoint consisted of procedure time, while in the remaining trials the primary outcomes consisted of contrast volume, 7 operator radiation exposure, 17 or strategy success. 16 The evaluation of risk of bias and overall quality of included trials are reported in Supporting Information Table S3.…”

“…Several randomized trials investigated the performance of either standard Judkins-shaped or dedicated catheters for transradial coronary angiography. 5,7,8,[14][15][16][17] In principle, these latter should be timesaving by avoiding repeat insertion of catheters and might concur at reducing the risk of spasm and/or occlusion through less injury of RA. 4 However, as accumulated evidence does not consistently favor one strategy over another, we performed a meta-analysis of randomized trials, which assigned ≈2,000 patients either to dual-or singlecatheter strategies for transradial coronary angiography.…”

“…20 Consistent with these findings, all trials included in this analysis graded the stability of single catheters during coronary angiography as inadequate in comparison to that of standard catheters. 5,7,8,[14][15][16][17] This mechanical behavior, which leads to unselective injection of contrast medium, incomplete filling of coronary arteries and poor image quality, is likely to counterbalance any potential advantage of single-catheter strategy.…”

“…5 The objective of a single-catheter strategy is to save time and to avoid mechanical irritation and injury of the RA due to catheter exchange, possibly reducing patient discomfort and the risk of arterial occlusion after transradial procedures. 6 However, recent studies investigating dual-versus single-catheter strategy for transradial coronary angiography led to inconsistent results 7,8 and a dual-catheter strategy still represents the standard approach among approximately 40% of operators. 3 To gain more insight into this topic, we performed a meta-analysis of randomized trials investigating the procedural and clinical performance of dual-versus single-catheter strategy for transradial coronary angiography.…”

Association of genetic variants in lncRNA GAS5/miR‐21/mTOR axis with risk and prognosis of coronary artery disease among a Chinese population

“…From April 2017 to February 2019, 436 patients with CHD, diagnosed by coronary angiography (CAG) according to Judkins method, 27,28 were recruited from the First Naval Hospital of Southern Theater Command. They were incorporated under following conditions: (a) over 50 years old; (b) in accordance with CHD diagnostic criteria which was formulated by American College of Cardiology/American Heart Association in 2007; and (c) coronary angiography revealed that stenosis was present in one of three major vessels, or main branches of coronary was ≥50%.…”
