Superior efficacy of pulmonary vein isolation with online contact force measurement persists after the learning period: a prospective case control study.

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
purposeUse of online contact force (CF) measurement during circumferential pulmonary vein (PV) isolation (CPVI) for atrial fibrillation (AF) has demonstrated improvements in procedural parameters and mid-term clinical outcome. However, it is unknown if experience gained with CF measuring catheters improves the efficacy of subsequent CPVI procedures performed without CF measurement.
methodsThis prospective trial compared procedural results of CPVI performed without a CF measuring catheter to a control group performed with a CF measuring catheter, by an operator with prior experience with CF technology..
resultsThirty-six eligible paroxysmal (n = 27) or persistent (n = 9) AF patients were consecutively enrolled. Twelve patients underwent CPVI with the non-CF catheter (CF- group) in a recall period and 24 with the CF catheter (CF+ group). After the first circumferential lesion set, the number of PV pairs requiring additional touch-up lesions to achieve electrical isolation was significantly less in the CF+ group (2 of 48 (4.2 %) vs. 7 of 24 (29.2 %) in the CF+ and CF- groups, respectively, p = 0.005). The procedure time was significantly lower in the CF+ group (117.9 ± 23.3 vs. 134.1 ± 25.3 min, p = 0.033). Radiofrequency (RF) and fluoroscopy time did not differ between groups (31.5 ± 7.1 vs. 31.8 ± 7.0 min and 11.8 ± 5.6 vs. 11.0 ± 5.8 min in the CF+ and the CF- group, respectively)
conclusionsWith the use of online CF measurement, PV isolation is more frequently complete following the first circumferential lesion set. A previous learning period with direct CF feedback is not a substitute for real-time direct CF measurement to maintain this advantage.
