Transseptal Puncture and Cryoballoon Ablation of Atrial Fibrillation in Patients with Atrial Septal Occluder or Atrial Septal Defect Surgical Repair: A Single Center Experience.
Article in Anatolian journal of cardiology, 2024. 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
backgroundAtrial fibrillation (AF) is a common arrhythmia in patients with atrial septal defect (ASD). Cryoballoon ablation (CA) is a safe and efficient method for pulmonary vein (PV) isolation in the treatment of AF. Achieving left atrial access may be difficult in patients with atrial septal occluders (ASO) or surgical repair of ASD. The aim of this study was to present our experience with the efficacy and safety of transseptal puncture and AF ablation in CA in this subset of patients.
methodsWe retrieved our data about patients with ASO or surgical repair of ASD undergoing cryoballoon AF ablation procedures at our center between August 2019 and January 2022.
resultsNine patients (age 43.88 ± 9.73 years) with AF (5 paroxysmal and 4 persistent) and ASO or surgical repair of ASD were enrolled. All three patients had a 28 mm Amplatzer ASO device which occupied the whole septum, and direct puncture through the ASO was performed. Sequential balloon dilatation was performed in 2 patients with surgical ASD repair and all 3 patients with ASO. Four of 6 patients (66.7%) in the surgical repair group required transesophageal echocardiography during transseptal puncture. The endpoint of the procedure, isolation of all PVs, was achieved in all 9 patients. None of the patients had evidence of an interatrial shunt or pericardial effusion at the end of the procedure. Total procedural time (123 ± 28 minutes vs. 63 ± 21 minutes, P = .024) and total fluoroscopy time (41 ± 5 minutes vs. 23 ± 8 minutes, P = .024) were significantly higher in the percutaneous closure group.
conclusionsIn patients with ASO or surgical repair of ASD, CA of AF might be feasible, safe, and effective. The balloon dilatation of the interatrial septum (IAS) might assist transseptal access through the ASO or a surgically repaired thickened IAS.
