Radiofrequency catheter ablation-associated silent iatrogenic right ventricular pseudoaneurysm: a case report and literature review.
Article in Frontiers in cardiovascular medicine, 2025. 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
Background: Right ventricular pseudoaneurysm (RVP) encased by adjacent pericardial or scar tissue is rare but can be a fatal sequela of cardiac rupture. Differentiating between pseudoaneurysms and true aneurysms is important because they have different natural histories and require distinct treatments. Radiofrequency catheter ablation (RFCA) is a potential cause of RVP; however, RFCA-associated RVP incidence and management remain unclear. Case presentation: An 88-year-old woman with refractory paroxysmal supraventricular tachycardia was admitted to our hospital. We performed an electrophysiological study, which led to a final diagnosis of atrioventricular nodal reentrant tachycardia, for which successful RFCA was performed. On post-procedural day 2, echocardiography revealed a small right ventricular apical outpouching. Cardiac computed tomography angiography led to the correct diagnosis of RVP, which was successfully treated with surgical repair. The postoperative course was uneventful. Conclusions: We describe a unique case of RFCA-associated apical RVP. This case highlights the importance of the potential risk of iatrogenic RVP and the value of cardiac computed tomography angiography in diagnosing RVP in patients with right ventricular outpouching.
