Coronary artery vasospasms (CAVs) during pulmonary vein isolation have been reported, but the mechanism remains unclear. We experienced a rare case of CAVs caused by radiofrequency (RF) applications to sites with massive epicardial adipose tissue (EAT) attached. Because EAT contains ganglionated plexuses, RF application may have caused an autonomic nervous system imbalance, which thereby provoked severe CAVs.

Lead dislodgement following cardiac implantable electronic device (CIED) generator change is rare. We report a case including the postulate mechanism of an isolated left ventricular lead dislodgement 3 months after cardiac resynchronization therapy defibrillator pulse generator change.

The acquisition of good contact force for radiofrequency catheter ablation of ventricular premature complexes (VPCs) originating from the basal septum of the left ventricle (LV) is often difficult. We describe a case of VPCs originating from the basal septum of the LV, which were successfully eliminated by applying radiofrequency at the right atrium (RA) side of the atrioventricular septum (AVS) without causing any significant impairment of atrioventricular conduction because the ablation catheter could obtain better contact force through the RA approach...

A 46-year-old female with a body mass index of 38.9 kg/m2 and no organic heart disease underwent a subcutaneous implantable cardioverter-defibrillator implantation for secondary prevention of sudden cardiac death in the setting of idiopathic ventricular fibrillation. Defibrillation threshold (DFT) testing during implantation detected high shock impedance and high DFT. Fluoroscopy revealed subcoil fat between the lead and the sternum, which we suspected was the reason for the high shock impedance and high DFT...

An important therapeutic modality for heart failure with left ventricular dyssynchrony, left ventricular lead placement, cannot be achieved due to anatomic challenges in some cases. In the current case, a novel implantation technique to overcome an anatomic difficulty, angled takeoff of the side branch of the coronary sinus, was presented.

Background: Traditionally the right ventricular (RV) pacing lead is placed in the RV apex in cardiac resynchronization therapy (CRT). It is not clear whether nonapical placement of the RV lead is associated with a better response to CRT. We aimed to perform a meta-analysis of all randomized controlled trials (RCTs) that compared apical and nonapical RV lead placement in CRT. Methods: We searched PubMed, EMBASE, Cochrane, Scopus, and relevant references for studies and performed meta-analysis using random effects model...

Background: Effects of nonparoxysmal atrial fibrillation (non-PAF) ablation targeting complex fractionated atrial electrogram (CFAE) areas and/or low voltage areas (LVAs) are still controversial. Methods and Results: A recently developed online real-time phase mapping system (ExTRa Mapping) was used to conduct LVA mapping and simultaneous ExTRa and CFAE mapping in 28 non-PAF patients after pulmonary vein isolation (PVI). Nonpassively activated areas, in the form of meandering rotors and/or multiple wavelets assumed to contain non-PAF drivers, partly overlapped with CFAE/LVAs but not always coincided with them...

Background: The phase III Japanese Rivaroxaban Once-Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (J-ROCKET AF) showed that the rivaroxaban group had a lower event rate of intracranial bleeding than the warfarin group and that rivaroxaban was noninferior to warfarin for the principal safety outcome. However, safety and effectiveness data from unselected patients with AF in everyday clinical practice in Japan are lacking...

Background: Rhythm outcomes after the pulmonary vein isolation (PVI) using the cryoballoon (CB) are reported to be excellent. However, the lesions after CB ablation have not been well discussed. We sought to characterize and compare the lesion formation after CB ablation with that after radiofrequency (RF) ablation. Methods: A total of 42 consecutive patients who underwent PVI were enrolled (29 in the CB group and 13 in the RF group). The PVI lesions were assessed by late gadolinium enhancement magnetic resonance imaging 1-3 months after the PVI...

Background: There are limited data on uninterrupted anticoagulation with direct oral anticoagulants during catheter ablation for atrial fibrillation (AF), particularly in Japan. We planned a subgroup analysis of the RE-CIRCUIT study, comparing the use of uninterrupted dabigatran therapy with warfarin therapy during catheter ablation among the Japanese subgroup and with that in the total population. Methods: The RE-CIRCUIT study utilized a prospective, randomized, open-label, blinded endpoint design, and the primary endpoint was the incidence of major bleeding events (MBEs)...

Background: Whether nonsustained ventricular tachycardia (NSVT) is a marker of increased risk of sustained ventricular tachyarrhythmias (VTAs) remains to be established in patients receiving cardiac resynchronization therapy with a defibrillator (CRT-D) for primary prevention. Methods: Among the follow-up data of the Japan cardiac device treatment registry (JCDTR) with an implantation date between January 2011 and August 2015, information regarding a history of NSVT before the CRT-D implantation for primary prevention had been registered in 269 patients...

Background: Availability of portable and home-based electrocardiography (ECG) is an important medical innovation, which has a potential to transform medical care. We performed this review to understand the current state of out-of-hospital portable ECG technologies with respect to their scope, ease of use, data transmission capabilities, and diagnostic accuracy. Methods: We conducted PubMed and Internet searches for "handheld" or "wearable" or "patch" electrocardiography devices to enlist available technologies...

Ranolazine is a new medication for the treatment of refractory angina. However, except its anti-anginal properties, it has been found to act as an anti-arrhythmic. The aim of our systematic review is to present the existing data about the impact of ranolazine in ventricular arrhythmias. We searched MEDLINE and Cochrane databases as well clinicaltrials.gov until September 1, 2017 to find all studies (clinical trials, observational studies, case reports/series) reported data about the impact of ranolazine in ventricular arrhythmias...

We reported a challenging transvenous lead extraction procedure for lead failure in a child with congenital heart disease. Our report demonstrates that the new hand-powered bidirectional rotational Evolution RL (Cook Medical, USA) mechanical extraction sheath is an effective and safe tool for the extraction of chronically implanted leads in children.

Although atrial fibrillation (AF) often exists in patients with hypertrophic obstructive cardiomyopathy (HOCM), combination of tricuspid regurgitation (TR) and AF after implantation of pacemaker/implantable cardioverter defibrillator (ICD) lead and its optimal management have not been well discussed in this population. Herein, we present a patient with HOCM who subsequently died due to severe heart failure and deterioration of TR following ICD lead placement with AF. Autopsy findings demonstrated that ICD leads were entrapped by anomaly structure in the right atrium and ventricle, which might affect deterioration of TR...

Wireless left ventricular endocardial pacing with the WiSE CRT system has recently become available as alternative to conventional epicardial CRT pacing. We report the first comparison of the acute electrical and hemodynamic response produced by the two CRT pacing modalities in a patient undergoing WiSE CRT implant after a failed conventional CRT procedure. WiSE CRT pacing showed an additive acute benefit compared with conventional CRT. These findings could potentially translate into long-term clinical benefit and introduce the potential for tri-ventricular pacing using both systems simultaneously...
