Successful Takeuchi Repair in a 48-Year-Old Woman With ALCAPA.

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
backgroundAnomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly, with high mortality if untreated. In adult-type ALCAPA, the risk of subclinical ischemia and sudden cardiac death persists. Surgical correction is generally recommended, yet the optimal surgical approach in adults remains debated. CASE SUMMARY: A 48-year-old woman presented with exertional angina. Imaging revealed ALCAPA, with the left coronary artery arising from the nonfacing sinus of the pulmonary artery. Given the anatomical challenge of direct reimplantation and the patient's young age, Takeuchi repair was performed. Postoperative recovery was uneventful, with restored dual coronary circulation and normal ventricular function. DISCUSSION: Although direct coronary reimplantation is the preferred treatment in children, it may be technically difficult in adults. Takeuchi repair offers an option in anatomically unfavorable cases, though it carries a risk of late complications.
conclusionsIn anatomically complex adult ALCAPA cases, Takeuchi repair is a valuable alternative to direct reimplantation or coronary artery bypass grafting. Careful long-term follow-up remains essential.
