Is single-catheter technique for coronary angiography an optimal tool for beginners in interventional cardiology?-randomized controlled study TRACT 2: Transradial Coronary Angiography Trial 2.
Article in Cardiovascular diagnosis and therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Transradial coronary angiography can be performed using a dual-catheter technique (DCT) or single-catheter technique (SCT). The current study aimed to compare DxTerity SCT Ultra and the Trapease curve SCT catheters with DCT catheters in procedures performed by young, less experienced, interventional cardiologists. Methods: For this prospective, single-blinded, randomized study 107 were enrolled and assigned to 1 of 3 groups. They underwent planned coronary angiography at the Second Department of Cardiology Jagiellonian University in Kraków. In groups 1 (n=37) and 2 (n=35), DxTerity SCT Ultra catheters and the Trapease curve were used, respectively. In control group 3 (n=35), standard DCT Judkins catheters were applied. One patient was excluded from group 2, bringing the total number of cases analysed to 106. The study endpoints comprised the percentage of optimal stability, proper ostial artery engagement, a good quality angiogram, the duration of each procedure stage, the amount of contrast and the radiation dose. Results: The highest percentage of optimal stability was observed in group 1 for the right coronary artery (RCA): 94%, and in group 3, for the left coronary artery (LCA): 85%. The necessity to change the catheter was most common in group 2. Group 1 was characterised by a shorter total procedural time. The contrast volume was higher in group 2, while there were no differences in radiation dose. Conclusions: SCT is at least as adequate as DCT for young cardiologists. SCT was associated with lower necessity of catheter exchange during RCA visualization. The DxTerity Ultra curve catheter allows shortening the total procedure time.
