Transthoracic echocardiography features of adult-type anomalous left coronary artery from the pulmonary artery before and after surgery: highlights from observational study in a single center of China.
Observational study in The international journal of cardiovascular imaging, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
To review the imaging characteristics of adult-type anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and evaluate the post-operative echocardiographic features. The transthoracic echocardiography (TTE) records and invasive coronary angiography (ICA), coronary computed tomography angiography (CTA) or operative findings of thirty adult patients with final diagnosis of ALCAPA were reviewed at our center. The diagnostic reliability of TTE was determined by comparing its results with that of ICA/CTA, and the echocardiographic features of the patients during early visit and post-operative follow-up were summarized. The coincidence rate of TTE and ICA/CTA diagnosing ALCAPA was 96.3% (26/27), and one case was misdiagnosed as coronary artery fistula. All patients showed abnormal left coronary ostium arising from the pulmonary trunk with retrograde coronary artery flow, 20 patients had enlarged right coronary artery (RCA), and 20 showed abundant inter-coronary septal coronary collaterals. Left ventricle (LV) abnormalities such as wall thinning, abnormal wall motion, papillary muscle fibrosis, mitral valve (MV) prolapse and moderate-severe mitral regurgitation (MR) were respectively observed in 4, 7, 10, 8 and 10 patients. Three patients showed ventricular septal defect, patent foramen ovale and tetralogy of Fallot respectively. Post-operative data was available for 12 patients, and showed that the diameter of RCA, size of left atrium (LA) and LV were decreased after surgery compared to the respective pre-operative values. Furthermore, inter-coronary septal coronary collaterals lessened in 8 of these patients. Although 6 patients showed residual mild MR, moderate or severe MR was not observed, and the ejection fraction (EF) also showed no obvious changes before and after surgery. TTE is a non-invasive diagnostic tool for adult-type ALCAPA, and can indicate abnormal coronary origin, collateral arteries and other associated malformations. Some of the structural and hemodynamic parameters of adult-type ALCAPA were improved after surgery.
