Standardized unfold mapping: a technique to permit left atrial regional data display and analysis

Purpose Left atrial arrhythmia substrate assessment can involve multiple imaging and electrical modalities, but visual analysis of data on 3D surfaces is time-consuming and suffers from limited reproducibility. Unfold maps (e.g., the left ventricular bull’s eye plot) allow 2D visualization, facilitate multimodal data representation, and provide a common reference space for ...

Inappropriate implantable cardioverter defibrillator shocks—incidence, effect, and implications for driver licensing

Purpose Patients with implantable cardioverter defibrillators (ICDs) have an ongoing risk of sudden incapacitation that may cause traffic accidents. However, there are limited data on the magnitude of this risk after inappropriate ICD therapies. We studied the rate of syncope associated with inappropriate ICD therapies to provide a scientific basis for formulating driving ...

Identifying patients with less potential to benefit from implantable cardioverter-defibrillator therapy: comparison of the performance of four risk scoring systems

Purpose Patients at high non-sudden cardiac death risk may gain no significant benefit from implantable cardioverter-defibrillator (ICD) therapy. A number of approaches have been proposed to identify these patients, including single clinical markers and more complex scoring systems. The aims of this study were to use the proposed scoring systems to (1) establish how many current ...

Adenosine administration during hybrid atrial fibrillation ablation to test dormant pulmonary vein conduction

Background Adenosine administration after initial pulmonary vein isolation (PVI) reveals dormant conduction and predicts atrial fibrillation (AF) recurrence. Elimination of dormant conduction when present may increase a long-term success rate of AF ablation procedures. There are no studies till date using adenosine to reveal acute reconduction of pulmonary veins (PVs) after ...

Long-term cerebral thromboembolic complications of transapical endocardial resynchronization therapy

Purpose Cardiac resynchronization therapy (CRT) is an established therapeutic option in selected heart failure patients (pts). However, the transvenous left ventricular (LV) lead implantation remains ineffectual in a considerable number of pts. Transapical LV (TALV) lead implantation is an alternative minimally invasive, surgical, endocardial implantation technique. The aim of the ...

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 that ...

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

Purpose Data 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. Methods The 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 ...
