Lateral atrial septal defect closure with induced ventricular fibrillation versus cardioplegic arrest.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Minimally invasive surgical closure of atrial septal defects is gaining widespread acceptance and can be performed via a right midaxillary thoracotomy. In addition, the procedure can be performed in ischaemic cardiac arrest or fibrillation with a core body temperature between 34°C and 36°C.
objectivesWe present our single-centre results of paediatric patients who underwent surgical atrial septal defect II closure via lateral thoracotomy.
methodsRetrospective analysis. Patients were divided into a cardiac arrest group and a cardiac fibrillation group. All procedures were performed via right midaxillary thoracotomy through a single incision without side ports.
resultsAll 37 consecutive patients between March 2019 and August 2022 (median age 3 years; percentile 25th: 2; 75th: 5 years) in both groups were free of mortality and postoperative morbidity such as haemodynamically relevant residual shunt or malignant arrhythmias. Cardiopulmonary bypass time was significantly shorter in the fibrillation group (mean: 34.7 min vs 52.6 min, P = 0.01), and all patients were weaned off the ventilator immediately postoperatively. Length of the intensive care unit stay was not different between the 2 groups. Postoperative hospital stay was significantly longer in patients with cardiac arrest (mean: 5.6 days vs 4.9 days, P = 0.04). Postoperative laboratory parameters did not differ between the 2 groups. All patients were discharged with normal left ventricular function and normalized cardiac enzymes.
conclusionsMinimally invasive closure of an atrial septal defect during atrial fibrillation is a safe procedure with results comparable to those of an induced cardiac arrest procedure.
