Myocardial injury and pericarditis after combined left atrial and coronary sinus ablation in Wolff-Parkinson-White syndrome: a case report.
Article in BMC cardiovascular disorders, 2020. 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
backgroundRadiofrequency catheter ablation is an established procedure with a high success rate for treating Wolff-Parkinson-White (WPW) syndrome. Rare complications post-ablation may nonetheless occur particularly associated with coronary sinus. Identifying and avoiding these complications remains a challenge. CASE PRESENTATION: A 66-year-old woman with WPW syndrome was admitted to the hospital due to frequent attacks of paroxysmal tachycardia. During electrophysiological study, an accessory pathway was thought to connect the posterior wall of the left ventricle. The patient underwent Radiofrequency (RF) catheter ablation. The procedure was time-consuming because of combined left atrial and coronary sinus ablation. The total amount of radiofrequency application energy in the coronary sinus was 6800 J. After the operation, widespread concave ST-segment elevation, significantly increased value of serum troponin I and mild pericardial effusion were identified, but the patient did not show any symptoms. Therefore, the patient was suspected to have myocardial injury and pericarditis caused by ablation-related injury. The patient was uneventfully discharged five days after the procedure with a significantly decreased value of troponin I. The reexamined electrocardiogram was normal after three weeks.
conclusionsTo the best of our knowledge, this is the first study to report on myocardial injury and pericarditis after combined left atrial and coronary sinus ablation in WPW syndrome. Our findings underscore the need for detailed mapping and careful ablation with low energy, as well as the merits of identifying myocardial infarction after coronary sinus ablation.
