On the Quest for the Best Freeze: Predictors of Late Pulmonary Vein Reconnections After Second-Generation Cryoballoon Ablation.
BACKGROUND The second-generation cryoballoon is effective in achieving acute pulmonary vein isolation (PVI) and favorable clinical outcome. To date, no data are available on factors affecting late PV reconnection after second-generation cryoballoon ablation. METHODS AND RESULTS A total of 29 consecutive patients (25 male, 86.2%; mean age 57.8±13.8 years) underwent a repeat procedure, after a ...
متن کاملOne-year clinical outcome after pulmonary vein isolation using the second-generation 28-mm cryoballoon.
BACKGROUND The use of second-generation cryoballoon for pulmonary vein isolation in patients with paroxysmal atrial fibrillation has demonstrated encouraging acute and mid-term results. Long-term outcome data are not yet available. METHODS AND RESULTS Fifty patients (18 women; mean age, 61±11 years; mean left atrial diameter, 43±5 mm) with paroxysmal (36 of 50 patients; 72%) or short-standing...
متن کاملOnce Isolated, Always Isolated? Incidence and Characteristics of Pulmonary Vein Reconduction After Second-Generation Cryoballoon-Based Pulmonary Vein Isolation.
BACKGROUND The second-generation cryoballoon delivers effective pulmonary vein isolation (PVI) associated with superior 1-year clinical outcome. However, data on reconduction of previously isolated PV are sparse. METHODS AND RESULTS A total of 421 patients underwent second-generation 28-mm cryoballoon-based PVI in 2 centers (St. George's hospital and Harburg hospital, Hamburg, Germany) betwee...
متن کاملPulmonary vein stenosis after second-generation cryoballoon ablation for atrial fibrillation
Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation for atrial fibrillation (AF), especially in paroxysmal 1 AF patients. In addition to a radiofrequency ablation catheter, a cryoballoon has been proven as an effective technology in PVI for AF. Recently several randomized trials have shown that cryoballoon ablation was noninferior to radiofrequency ablation with respect to ef...
متن کاملElectromyographic monitoring for prevention of phrenic nerve palsy in second-generation cryoballoon procedures.
BACKGROUND Electromyography-guided phrenic nerve (PN) monitoring using a catheter positioned in a hepatic vein can aid in preventing phrenic nerve palsy (PNP) during cryoballoon ablation for atrial fibrillation. We wanted to evaluate the feasibility and efficacy of PN monitoring during procedures using second-generation cryoballoons. METHODS AND RESULTS This study included 140 patients (43 wo...
