Application of a rapid exchange extension catheter technique in type B2/C nonocclusive coronary intervention
Article in World journal of clinical cases, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn transradial intervention procedures, poor back-up support and noncoaxial alignment of the guide catheter (GC) may result in failure of the balloon or stent to reach the targeted lesion. Methods to provide extra back-up support using the original GC and wire can improve procedural success with reduced complications. A rapid exchange guide extension catheter provides convenient and efficient back-up support while preserving the initial GC and inserted wire.
aimTo evaluate the efficacy and safety of rapid exchange extension catheter in the treatment of type B2/C nonocclusive coronary lesions
methodsA total of 135 patients with type B2/C nonocclusive lesions who were treated
resultsThe most common indication for the use of a rapid exchange extension catheter was vascular tortuosity (37.8%), followed by heavy calcification (28.9%), long lesions (20.0%), proximal stent (6.7%), in-stent restenosis (5.2%), and coronary origin anomalies (1.5%). The following technologies failed in passing targeted lesions before delivering the rapid exchange catheter: Multiple predilatation technique (57%), buddy wire technique (33.4%), balloon anchoring technique (5.9%), and cutting balloon modification (3.7%). The mean depth of the extension catheter intubation was 20.56 ± 13.05 mm, and the mean rapid exchange catheter service time was 18.9 ± 9.7 min. The mean length and diameter of stents were 33.5 ± 14.4 mm and 2.75 ± 0.45 mm, respectively. The total rate of technique success (balloon or stent successful crossing of the target lesion with this technique) was 94.8%.
conclusionThe rapid exchange extension catheter technique showed acceptable safety and efficacy in the transradial coronary interventions of type B2/C nonocclusive coronary lesions. We recommend this technique to assist in complex lesion intervention
