This complaint is from a literature source.The following complications were reported in this publication: it was reported that 1 patient who underwent pulmonary vein isolation cardiac ablation suffered pneumonia (respiratory infection).Intervention was not reported.There are 0 death events and 0 device malfunctions reported in this publication.Model and catalog number are not available, but the suspected device is thermocool smarttouch (st).Other biosense webster devices that were also used in this study: lasso ,carto visitag non-biosense webster devices that were also used in this study: na.Publication details: title: reproducibility of pulmonary vein isolation guided by the ablation index: 1-year outcome of the air registry.Objective: ablation index (ai) is a new lesion quality marker that has been demonstrated to allow a high single-procedure arrhythmia-free survival in single-center studies.This prospective, multi-center study was designed to evaluate the reproducibility of pulmonary vein (pv) isolation guided by the ai.Methods: a total of 490 consecutive patients with paroxysmal (80.4%) and persistent af underwent first time pv isolation and were divided in four study groups according to operator's preference in choosing the ablation catheter (a contact force (st) or contact force surround flow (stsf) catheter) and the ai setting (330-450 or 380-500 at anterior wall or posterior wall, respectively).
