OBJECTIVES: This study sought to compare long-term arrhythmia-free survival between electrical circumferential pulmonary vein isolation (PVI) and PVI with the endpoint of unexcitability along the ablation line. BACKGROUND: PVI is the standard ablation strategy of paroxysmal atrial fibrillation, although arrhythmia recurrence in long-term follow-up (FU) is high. The endpoint of unexcitability along the ablation line results in decreased arrhythmia recurrence compared to electrical PVI in 1-year FU...

OBJECTIVES: The goal of this study was to determine whether a strategy of early re-isolation of pulmonary vein (PV) reconnection in all patients, regardless of symptoms, would reduce the recurrence of atrial fibrillation (AF) and improve quality of life. BACKGROUND: Lasting pulmonary vein isolation (PVI) remains elusive. PV reconnection is strongly linked to the recurrence of arrhythmia. METHODS: A total of 80 patients with paroxysmal AF were randomized 1:1 after contact force-guided PVI to receive either standard care or undergo a repeat electrophysiology study after 2 months regardless of symptoms (repeat study)...

OBJECTIVES: This study sought to determine the exact period after pulmonary vein antrum isolation (PVI) during which early recurrence of atrial tachyarrhythmia (ERAT) does not predict late arrhythmia recurrence (LR), in order to better define the blanking period. BACKGROUND: Recurrence of atrial fibrillation after PVI is not uncommon. The first 3 months after PVI have been commonly treated as a blanking period, during which ERAT is not thought to predict LR after PVI; however, recent studies have shown that ERAT does predict LR...

BACKGROUND: The outcomes from pulmonary vein isolation (PVI) for atrial fibrillation (AF) are suboptimal, but the benefits of additional lesion sets remain unproven. Recent studies propose ablation of AF drivers improves outcomes over PVI, yet with conflicting reports in the literature. We undertook a systematic literature review and meta-analysis to determine outcomes from ablation of AF drivers in addition to PVI or as a stand-alone procedure. METHODS: Database search was done using the terms atrial fibrillation and ablation or catheter ablation and driver or rotor or focal impulse or FIRM (Focal Impulse and Rotor Modulation)...

Aims: The efficacy of the second-generation cryoballoon (CB) ablation in patients with atrial fibrillation (AF) has been demonstrated previously. Data on the efficacy of CB ablation in elderly patients is missing. The aim of this study was to evaluate the long-term success rate of pulmonary vein isolation (PVI) in patients ≥75 years vs. <75 years using the second-generation 28mm CB. Methods and results: Eighty patients [n = 40 ≥75 years (Group 1); n = 40 <75 years (Group 2)] with paroxysmal [n = 37 (46%) or persistent (n = 43 (54%)] AF were included...

BACKGROUND: Despite advancements, the goal of durable pulmonary vein isolation (PVI) in all patients undergoing ablation for atrial fibrillation (AF) remains elusive. New high density mapping allows detection of concealed low voltage signals (CLVS) that persist after PVI and may represent vulnerabilities in the lesion set. OBJECTIVE: To determine the incidence of CLVSs after PVI and the effect of CLVS ablation on outcomes. METHODS: We conducted a case control study comparing 150 patients undergoing High Density Mapping (HDM) guided PVI and subsequent CLVS mapping and ablation (39 redo, 111 de novo) against 452 historical controls undergoing traditional PVI alone...

Outpatient use of atherectomy for peripheral arterial disease has grown rapidly and outcomes are poorly understood. We analyzed outcomes of atherectomy done for claudication, comparing office and hospital outpatient settings. Analysis of Medicare Part B claims data was performed for incident femoral-popliteal or tibial-peroneal atherectomy from 2012 to 2014. Longitudinal analysis assessed services 18 months before, during, and up to 18 months after the incident peripheral vascular intervention (PVI). Differences between office-based and hospital outpatient-based settings were assessed using χ2 and Fisher exact tests...

OBJECTIVE: Pulmonary vein isolation (PVI) ablation has emerged as the gold standard of ablative strategies to treat medically refractory paroxysmal and persistent atrial fibrillation (AF). Regardless of the superiority of catheter ablation based on PVI over antiarrhythmic drug therapy, recurrence rates of AF remain higher than desired. PVI via cryoablation has rapidly become a mainstream treatment for AF, due to its effectiveness and fast learning curve. Our objective was to assess the safety and efficacy of cryoablation in a single referral center...

PURPOSE: We compared the contour of learning curves of two "single-shot" devices used for pulmonary vein isolation (PVI) for safety and procedural data. METHODS: We performed a retrospective analysis comparing the first 60 PVI performed at our center using a pulmonary vein ablation catheter (PVAC) array (39 male, mean age 57 years, 42 paroxysmal AF) to the first 60 first PVI using the Cryoballoon (44 male, mean age 59 years, 22 paroxysmal AF). Both groups were further divided into tertiles, where T1 regroups the first 20 ablations, T2 the following 20, and T3 the last 20 ablations...

Atrial fibrillation (AF) affects 1-2% of the population, and its prevalence is estimated to double in the next 50 years as the population ages. AF results in impaired patients' life quality, deteriorated cardiac function and even increased mortality. Antiarrhythmic drugs frequently fail to restore sinus rhythm. Catheter ablation is a valuable treatment approach for AF, even as a first-line therapy strategy in selected patients. Effective electrical pulmonary vein isolation (PVI) is the cornerstone of all AF ablation strategies...

BACKGROUND: Hemodialysis (HD) has been shown to be an independent predictor of poor outcomes after femoropopliteal revascularization procedures in patients with chronic limb-threatening ischemia. However, HD patients tend to have isolated infrageniculate disease, an anatomic risk factor for inferior patency. We aimed to compare outcomes for HD versus non-HD patients after infrageniculate open lower extremity bypass (LEB) and endovascular peripheral vascular interventions (PVIs). METHODS: Data from the Society for Vascular Surgery Vascular Quality Initiative database (2008-2014) were analyzed...
