Tailored Ablation Strategies for Atrial Fibrillation With Common Inferior Pulmonary Vein Variants.

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
backgroundThe common inferior pulmonary vein (CIPV) is a rare anatomical variant that may complicate pulmonary vein isolation for atrial fibrillation (AF). We present tailored ablation strategies for AF patients with CIPV or CIPV-like anatomy.
methodsSix AF patients with CIPV were retrospectively analyzed. Pre- or postprocedural computed tomography and/or three-dimensional mapping identified the anatomy. Ablation was guided by voltage mapping, with lesions delivered only at sites with electrical activity.
resultsFour patients had paroxysmal AF and 2 patients had persistent AF. The right superior and left superior pulmonary veins were isolated in all cases. CIPV was treated with limited ostial ablation (n = 4), complete trunk isolation (n = 1), or single-ring posterior wall isolation (n = 1). No acute complications occurred. Over a mean follow-up of 14.2 months, 5 of the 6 patients remained free from AF recurrence.
conclusionsTailored ablation strategies based on imaging and voltage guidance allow safe and effective treatment of AF in patients with CIPV.
