PURPOSE: Obstructive sleep apnea (OSA) has been recognized as an independent risk factor for the development and progression of atrial fibrillation (AF). We aimed to investigate the changes in heart rate and atrial and ventricular ectopy after continuous positive airway pressure (CPAP) treatment in patients with OSA and AF. METHODS: Consecutive patients with AF underwent ambulatory sleep monitoring, and OSA was defined as an Apnea-Hypopnea-Index (AHI) ≥ 5/h...

PURPOSE: Device implantation requires fluoroscopic guidance, which carries inherent risks of ionizing radiation. We evaluated the impact of a low-dose fluoroscopic protocol on radiation exposure during device implantation. METHODS: All patients who underwent pacemaker or ICD implantation with new transvenous leads from July 2011 to January 2018 were included. A novel ALARA protocol consisting of ultra-low frame rates (2-3 frames/s), low dose/frame (6-18 mGy/frame), and use of the "air-gap" technique in patients < 20 kg was employed...

PURPOSE: Cryoballoon ablation (CBA) has become a standard treatment for recurrent atrial fibrillation (AF). There is need for improved CBA protocols. We aimed to demonstrate that a new protocol including minimum temperature (minT) reached could reduce procedure times and complications. METHODS: A new double factor protocol (DFP), based on the performance of one single shot per vein with variable duration, and conditional bonus shot, determined by time-to-effect (TTE) and minT, was compared with the conventional protocol (CP), with at least two shots per vein...

PURPOSE: Right ventricular pacing threshold (RVPT) may rise over time accompanied by the increased use of implantable cardiac pacemakers. However, risk factors for permanent RVPT increase are not fully clarified in patients without definite lead fracture and dislodgment. We aimed to evaluate the long-term performance of RV pacing leads and identify risk factors associated with the occurrence of permanent RVPT increase in this population. METHODS: Patients with first implantation of cardiac pacemakers from January 2008 to June 2016 were consecutively enrolled...

PURPOSE: Radiation exposure (RE) is a matter of concern for patients with congenital heart disease (CHD) who not infrequently need multiple interventional procedures under fluoroscopy guidance. We sought to evaluate the safety and feasibility of a minimally fluoroscopic approach in patients with CHD undergoing catheter ablation using a new image integration module (IIM). METHODS: Consecutive patients with CHD undergoing catheter ablation using the Carto Univu™ IIM were included...

BACKGROUND: There is a lack of compelling data regarding the benefit of percutaneous ventricular assist devices (PVAD) in patients undergoing ventricular tachycardia (VT) ablation. The study aims to conduct a meta-analysis comparing the safety and efficacy of PVAD versus no-PVAD (N-PVAD) during VT ablation. METHODS: Studies meeting criteria were systematically reviewed. Baseline characteristics and clinical outcomes were extracted and analyzed. A meta-analysis was performed using random-effects model to calculate risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI)...

BACKGROUND: A common approach to ablating along the posterior wall of the left atrium in atrial fibrillation ablation is to use low power with longer duration for durable lesions and reducing thermal injury. We hypothesize that similar lesions can be safely obtained at high power with low open-irrigation flow and low duration. METHODS: Twenty-two porcine ventricles were placed in a tissue bath with circulating 0.45% NaCl at a maintained temperature of 37 °C. Bipolar radiofrequency ablation (RFA) with a 4-mm-tip irrigated, force-sensing catheter was performed with various combinations of irrigation, power, and duration at 20g of contact force...

BACKGROUND: Time has been postulated as an important factor for electrical remodeling of the left atrium (LA) in persistent atrial fibrillation (AF) ('AF begets AF'). However, it is still a matter of debate if structural changes are the cause or consequence of AF. We sought to determine the clinical and invasive parameters, which correlate with LA scar as determined by voltage mapping, in patients with persistent AF. METHODS: Seventy consecutive patients undergoing ablation of persistent (49%) or long-standing persistent AF (51%), between January 2013 and February 2014, were enrolled in the study...

PURPOSE: Hemoptysis and pulmonary hemorrhage are rarely described as complications of cryoballoon ablation for pulmonary vein isolation (CB PVI). This study evaluated a large cohort to determine the frequency and risk factors for manifestation of these complications and assess the clinical relevance of hemoptysis after CB PVI. METHODS: Seven hundred fifteen consecutive patients (351 female) from a single-center database were evaluated to identify those who developed hemoptysis after CB PVI...

PURPOSE: The evolution of heart rhythm monitoring technology over the past few decades has seen a decline in the use and need of transtelephonic monitoring (TTM). We sought to establish a predicted date for the sun setting of TTM at our institution, as well as establish the current demographics of the patients still using this technology. METHODS: We retrospectively reviewed all patients with permanent pacemakers receiving routine device follow-up at our institution (Mayo Clinic-Rochester) between 2015 and 2018...

PURPOSE: There is a significant variation in the clinical approach of initiation and dose adjustment of dofetilide in atrial fibrillation (AF). Excessive QT prolongation could predispose patients to torsades de pointes (TdP), which can be fatal. METHODS: We performed a retrospective case-control study at Mayo Clinic Rochester (January 1, 2003 to December 31, 2016). "TdP risk" cases were defined as patients on dofetilide therapy for AF with subsequent TdP or excessive QTc prolongation requiring dose reduction or discontinuation (N = 31)...

BACKGROUND: Laser balloon (LB) and cryoballoon (CB) ablation are two balloon-based catheter ablation technologies used for atrial fibrillation (AF) ablation in recent years. However, the efficacy and the safety of LB ablation in comparison to CB ablation remained indeterminate. We sought to compare these two technologies by conducting meta-analysis of previous studies using both the CB and LB ablation systems for AF ablation. METHODS: We searched electronic scientific databases for studies of LB vs...

BACKGROUND: Cryoballoon pulmonary vein isolation (PVI) is commonly used for rhythm control of atrial fibrillation (AF). Data are limited examining the outcomes of cryoballoon PVI in patients with systolic dysfunction. We evaluate the impact of cryoballoon PVI in patients with systolic dysfunction. METHODS: We evaluated a single-center prospective registry of patients undergoing cryoballoon PVI between 8/2011 and 6/2016. Patients with systolic dysfunction (EF < 55%) between the time of AF diagnosis and their cryoballoon PVI procedure were assessed for AF recurrence at 6 months and 1 year post-procedure, with a 3-month blanking period...

Atrial fibrillation (AF) is an important risk factor for stroke. Although anticoagulation is effective in mitigating this risk, many high-risk patients are not anticoagulated in routine practice. Furthermore, as many as 50% of those who are prescribed an anticoagulant stop treatment within a year. This under treatment may be due, in part, to difficulty in navigating difficult decisions about initiating potentially lifelong therapy with significant costs, potential risks, and impact on daily life. To address these challenges, the most recent American guidelines issued a class I recommendation to use shared decision-making (SDM) to individualize patients' antithrombotic care...

BACKGROUND: Transmural lesions (TLs) are the crucial point for radiofrequency catheter ablation (RFCA) in atrial fibrillation (AF) patients. Previous studies have reported that complete positive unipolar electrogram (UP-EGM) after ablation is associated with transmural lesions. However, UP-EGM patterns may differ in different regions of continuous circular lesions (CCLs) around the pulmonary vein ostia after ablation. We aimed to analyze the different UP-EGM patterns in different CCL regions after ablation and the effectiveness of UP-EGM guided RFCA in paroxysmal atrial fibrillation (PAF)...
