Clinical experience with routine use of a single combined mapping and ablation catheter for isolation of pulmonary veins in patients with paroxysmal atrial fibrillation.

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
backgroundCatheter-based isolation of pulmonary veins has become established treatment for patients with paroxysmal atrial fibrillation. We wished to simplify the interventional procedure by using a single novel multipolar catheter for mapping and ablation in appropriate patients.
methodsSixty-four patients with paroxysmal atrial fibrillation scheduled for pulmonary vein isolation were screened by cardiac computed tomography for anatomic suitability to undergo a simplified procedure with the high-density mesh ablator catheter (MESH) as the only left atrial device. The procedure was undertaken in 38 patients matching the criteria of four clearly separated pulmonary veins with ostial diameters 15-25 mm; the remaining 26 patients served as a control group and were treated using a three-dimensional mapping system guided ablation using a circular mapping catheter and a single-point ablation catheter.
resultsIn all 38 patients, all four pulmonary veins could be accessed and mapped with the MESH. Using the MESH, electrical isolation was achieved in 142/148 (96%) pulmonary veins with recorded potentials. In the control group, 100/105 (95%) pulmonary veins with recorded potentials could be isolated. After 6 months, clinical results did not differ significantly between the two treatment groups.
conclusionIn appropriate patients, the routine single catheter approach with the MESH for mapping and ablation yields a high acute success rate despite the reduced complexity of the procedure. Long-term data on clinical success rates are needed to justify this simplified approach.
