1 · What the graph read from it

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.

2 · The registry

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

purposePulmonary vein antrum isolation by radiofrequency ablation has become a preferred treatment for atrial fibrillation. The aim of our research is to study the anatomy of the PVantrum and its related structures with special emphasis on the esophageal relation to the various components of the antrum, as thermal injury is a common complication.

methodsMediastinal contents were extracted "en bloc" from 30 human formalin fixed adult cadavers to study the posterior wall of the left atrium along with the esophagus.

resultsThe pulmonary antrum was measured. Each pulmonary ostium was assessed for circumference and muscle thickness. The esophagus was related to the left superior ostium in 90% of cases. The esophagus was traced on the atrial wall in each case; the distance from endocardium was measured at five equidistant lines. AV node distance from the right inferior pulmonary vein was 5 cm. The atrioventricular part of the membranous septum measured 4.2 mm.

conclusionsFor antral isolation the ablation lines are about 3 cm superior, 3.5 cm inferior and about 1 cm apart. The esophagus is ~ 12 mm away at the superior and ~ 7 mm away at the inferior ablation line. On the left ablation line this distance would diminish from 15 to 7 mm. The pulmonary ostial circumference is ~ 5 cm with muscle thickness varying from 0.7 to 4 mm. The left ostia need more ablative power as they have a 60% (1 mm) thicker muscle coat. Care should be taken while ablating round the left superior ostium as the esophagus lies 1-3 cm behind it in 90% of the cases.
