Ablation of atrial arrhythmias after lobectomy: high-density mapping and CT integration to guide individualized treatment.
Article in BMC cardiovascular disorders, 2026. 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
backgroundAtrial fibrillation is a known complication following thoracic surgery, with residual pulmonary vein (PV) stumps often implicated as sources of arrhythmogenic triggers. Existing literature suggests that these stumps can maintain ectopic activity, leading to arrhythmia recurrence. In this case, contrary to common findings, a PV stump in a post-lobectomy patient was found to be electrically inert, challenging the assumption that all such stumps are pro-arrhythmic. The absence of electrical activity in the stump suggests that its anatomical characteristics, such as being extremely short and even flat, may prevent it from acting as a trigger for atrial fibrillation. CASE PRESENTATION: A 64-year-old male with a history of right superior bilobectomy for a carcinoid tumor presented with symptomatic atrial flutter and paroxysmal atrial fibrillation. His medical history was significant for severe left ventricular dysfunction (Ejection Fraction, EF 25%), hypertension, and obesity. After confirming the absence of left atrial thrombus, he underwent a successful radiofrequency catheter ablation of the cavo-tricuspid isthmus (CTI), which terminated the atrial flutter. Subsequently, electroanatomic mapping of the left atrium was performed. Despite the history of lobectomy, mapping revealed no electrical activity originating from the right superior pulmonary vein stump. The remaining PVs were successfully isolated using radiofrequency energy. The patient remained in stable sinus rhythm without antiarrhythmic drugs at his 6-month follow-up.
conclusionsThis case demonstrates that a PV stump after lobectomy is not universally arrhythmogenic. The absence of electrical activity in the stump suggests that its anatomical characteristics, such as being extremely short, may prevent it from acting as a trigger for atrial fibrillation. This report suggests the potential value of detailed, individualized electroanatomic mapping in post-lobectomy patients before considering stump ablation. This patient-specific approach can help avoid unnecessary ablations, thereby minimizing procedural risks while ensuring that only clinically significant arrhythmogenic substrates are targeted.
