Left atrial appendage outflow velocity is superior to conventional criteria for predicting of maintenance of sinus rhythm after simple cryoablation of pulmonary vein orifices.

BACKGROUND We sought to identify factors favoring long-term restoration of sinus rhythm (SR) in patients with atrial fibrillation (AF) who underwent a simple cryoablation of pulmonary vein orifices (PV-cryo) as part of their cardiac surgery. METHODS AND RESULTS Of 101 patients with AF undergoing PV-cryo, the 71 in SR at discharge were grouped according to… (More)
