Ablation of atypical atrial flutters using ultra high density-activation sequence mapping

Purpose The purpose of this study was to evaluate ultra high density-activation sequence mapping (UHD-ASM) for ablating atypical atrial flutters. Methods For 23 patients with 31 atypical atrial flutters (AAF), we created UHD-ASM. Results Demographics age = 65.3 ± 8.5 years, male = 78%, left atrial size = 4.66 ± 0.64 cm, redo ablation 20/23(87%). AAF were left atrial in 30 (97...

Impact of new X-ray technology on patient dose in pacemaker and implantable cardioverter defibrillator (ICD) implantations

Purpose New X-ray technology providing new image processing techniques may reduce radiation exposure. The aim of this study was to quantify this radiation exposure reduction for patients during pacemaker and implantable cardioverter defibrillator (ICD) implantation. Methods In this retrospective study, 1185 consecutive patients who had undergone de novo pacemaker or ICD...

Hybrid ablation for atrial fibrillation: a systematic review

Purpose Hybrid ablation for AF is performed in a growing number of centers. Due to absence of guidelines, operative approaches and perioperative care differ per center. In this review, an overview of findings from published studies on hybrid ablations is given, and related topics are discussed (e.g., one- and two-stage approaches, lesion sets, and patient management). Methods A...

Patient’s age rather than severity of the arrhythmia influences the cost of medical treatment of atrioventricular nodal or atrioventricular reciprocating tachycardia

Purpose Radiofrequency ablation (RFA) is considered the treatment of choice in cases of atrioventricular nodal reciprocating tachycardia (AVNRT) and atrioventricular reciprocating tachycardia (AVRT). Published studies suggest a considerable time gap between the onset of the arrhythmia, correct diagnosis, and RFA which may reach 10–15 years. The cost of medical treatment during...

Atrial mapping during pulmonary vein pacing: a novel maneuver to detect and close residual conduction gaps in an ablation line

Background Location of residual conduction gaps on ablation lines around pulmonary veins (PV) is challenging, and several maneuvers have been described. Atrial mapping during PV pacing—the “pace and map” maneuver—could localize gaps. Methods and results We prospectively studied 209 patients undergoing PV isolation at a single institution over a 25-month period. In 24 (11.4...

Time-limited cryomapping during tachycardia: improved long-term outcomes for cryoablation of AVNRT

Purpose Cryothermal ablation (CTA) for atrioventricular nodal reentrant tachycardia (AVNRT) is considered safer than radiofrequency ablation (RFA) since it eliminates the risk of inadvertent AV block. However, it has not been widely adopted due to high late recurrence rate (LRR). In an effort to improve LRR, we evaluated a new approach to cryothermal mapping (CTM): “time to...

Medical specialty certification in the United States—a false idol?

Purpose Recent changes to medical specialty certification in the USA have prompted the process to come under intense scrutiny. Methods We review the history of board certification and the changes made to the process. As part of this review, we examine both literature and public record to examine the motives behind the changes made. We then review the legal challenges and changes...

Improved survival in patients enrolled promptly into remote monitoring following cardiac implantable electronic device implantation

Purpose Guidelines advocate remote monitoring (RM) in patients with a cardiac implantable electronic device (CIED). However, it is not known when RM should be initiated. We hypothesized that prompt initiation of RM (within 91 days of implant) is associated with improved survival compared to delayed initiation. Methods This retrospective, national, observational cohort study...

Contact forces during hybrid atrial fibrillation ablation: an in vitro evaluation

PurposeData on epicardial contact force efficacy in dual epicardial–endocardial atrial fibrillation ablation procedures are lacking. We present an in vitro study on the importance of epicardial and endocardial contact forces during this procedure.MethodsThe in vitro setup consists of two separate chambers, mimicking the endocardial and epicardial sides of the heart. A circuit...

Performance of a remote interrogation system for the in-hospital evaluation of cardiac implantable electronic devices

Purpose Patients with a cardiac implantable electronic device (CIED) often need device interrogation in an in-hospital environment. A diagnosis-only, remote interrogation device and process for CIED interrogation was developed to address this situation. Here, we describe our initial clinical experience with this system. Methods The LATITUDE Consult Communicator is a stand-alone...

A novel intra-operative, high-resolution atrial mapping approach

PurposeA new technique is demonstrated for extensive high-resolution intra-operative atrial mapping that will facilitate the localization of atrial fibrillation (AF) sources and identification of the substrate perpetuating AF.MethodsPrior to the start of extra-corporal circulation, a 8 × 24-electrode array (2-mm inter-electrode distance) is placed subsequently on all the right...

Non-invasive focus localization, right ventricular epicardial potential mapping in patients with an MRI-conditional pacemaker system ‐ a pilot study

BackgroundWith the advent of magnetic resonance imaging (MRI) conditional pacemaker systems, the possibility of performing MRI in pacemaker patients has been introduced. Besides for the detailed evaluation of atrial and ventricular volumes and function, MRI can be used in combination with body surface potential mapping (BSPM) in a non-invasive inverse potential mapping (IPM...

Usefulness of a crista catheter for 3-dimensional electroanatomical mapping of complex right atrial tachyarrhythmias

Purpose Right atrial (RA) tachyarrhythmias are not rare in patients with congenital heart disease and a history of cardiac surgery. This study investigated the usefulness of a crista catheter for 3-dimensional electroanatomical mapping of RA tachyarrhythmias. Methods We consecutively included 35 patients (age, 43.2 ± 15.6 years; 15 men) who underwent an electrophysiological study...

The genetic basis for inherited forms of sinoatrial dysfunction and atrioventricular node dysfunction

The sinoatrial node (SAN) and the atrioventricular node (AVN) are the anatomical and functional regions of the heart which play critical roles in the generation and conduction of the electrical impulse. Their functions are ensured by peculiar structural cytological properties and specific collections of ion channels. Impairment of SAN and AVN activity is generally acquired,but in...

Ambulatory respiratory rate trends identify patients at higher risk of worsening heart failure in implantable cardioverter defibrillator and biventricular device recipients: a novel ambulatory parameter to optimize heart failure management

Purpose Respiratory distress is the primary driver for heart failure (HF) hospitalization. Implantable pacemakers and defibrillators are capable of monitoring respiratory rate (RR) in ambulatory HF patients. We investigated changes in RR prior to HF hospitalizations and its near-term risk stratification power. Methods NOTICE-HF was an international multi-center study. Patients...
