Angioplasty of Anomalous Coronaries Arising from the Opposite Sinus with an Interarterial Course, is it Safe?
Article in Journal of the Saudi Heart Association, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe coronary artery with an interarterial course CAIAC is the most threatening coronary anomaly, especially if it concerns the left coronary. Percutaneous coronary intervention PCI is scarcely described given its low prevalence and lack of long-term outcome data. Therefore, we assessed through this case series the feasibility and safety of PCI in this population.
methodsThis is an observational multicentric study including patients with CAIAC arising from the opposite sinus of Valsalva. The primary endpoints were immediate angiographic success and target lesion revascularization.
resultsDuring the period of the study, we performed 27235 PCI in six Cath labs, 26 procedures concerning abnormal coronaries including 12 with CAIAC. The median age was 57 years extremes: 43-78 with male predominance 1:11. Anomalous coronary artery was Right coronary artery RCA in eight patients, Left main LM in three patients, and left anterior descending LAD in one patient. The stenosis was located in all cases in proximal segments beyond the inter-arterial course proximal LAD, the superior genius of the RCA, or the proximal segment of mid-RCA. Five patients showed slit-like ostium and all have an angle take-off <45° on CT scan. After a median follow-up of 24 months, four subjects presented target lesion revascularization TLR, all were initially treated with either a bare-metal stent or with balloons.
conclusionsPCI of patients with CAIAC is feasible and appears safe. The operator should carefully analyze the angiogram before PCI to choose the appropriate guiding catheter and should be acquainted with the different techniques for improving backup.
