BACKGROUND: Using third-party resources to manage remote monitoring (RM) data from implantable cardiac electronic devices (CIEDs) can assist in device clinic workflows. However, each hospital-acquired data is not used for further analysis as big data. METHODS AND RESULTS: We developed a real-time and automatically centralized system of CIED information from multiple hospitals. If the extensive data-based analysis suggests individual problems, it can be returned to each hospital...

Cardiac resynchronization therapy (CRT) is an established treatment for heart failure patients with left ventricular dysfunction and a left bundle branch block. However, its impact on right ventricular (RV) function remains uncertain. This cardiac magnetic resonance imaging study found that CRT did not improve RV volumes and function, and CRT-off during follow-up had an immediate detrimental effect on the RV, which may suggest potential unfavorable RV remodeling with RV pacing during CRT.

INTRODUCTION: Transvenous temporary pacemaker (TvTP) implantation is a critical procedure often performed under time limitations, playing a crucial role in patient survival. However, the amount of training provided for resident cardiologists is variable, due to the availability of patients. Thus, the use of simulators for this cardiologic procedure could be used as training tools. OBJECTIVE: The present study aimed to develop a simulator system for TvTP implantation based on electrograms, called ETTIS (Electrogram-guided Transvenous Temporary-pacemaker Implantation Simulator), and to evaluate its educational potential and cardiology residents' perceived learning efficacy as a training tool...

BACKGROUND: Recent studies have shown that atrial slow conduction velocity (CV) is associated with the perpetuation of atrial fibrillation (AF). However, the criteria of CV measurement have not been standardized. The aim of this study was to evaluate the relationship between the slow CV area (SCVA) measured by novel omnipolar technology (OT) and AF recurrence. METHODS: This study included 90 patients with AF who underwent initial pulmonary vein isolation (PVI). The segmented surface area of the SCVA was measured by left atrial (LA) electrophysiological mapping using OT before the PVI...

BACKGROUND: Atrial esophageal fistula (AEF) is a lethal complication that can occur post atrial fibrillation (AF) ablation. Esophageal injury (EI) is likely to be the initial lesion leading to AEF. Endoscopic examination is the gold standard for a diagnosis of EI but extensive endoscopic screening is invasive and costly. This study was conducted to determine whether fecal calprotectin (Fcal), a marker of inflammation throughout the intestinal tract, may be associated with the existence of esophageal injury...

Ventricular tachycardia ablation in the post-surgical patients is complicated by difficult epicardial access. Endocardial-only ablation may lead to failure which can be prevented by mapping and ablating inside the coronary venous system. Radiofrequency ablation inside the coronary venous system is dependent on anatomical and biophysical factors. Herein we report a ventricular tachycardia case necessitating bipolar ablation between the middle cardiac vein and the left ventricular endocardium.

The procedural success in the implantation of cardiac electric devices depends on both the implanted position and the electric performance. The capture threshold and the pacing output affect the estimated battery longevity. In a case with a high capture threshold, recapture and reimplantation of a leadless pacemaker are commonly recommended. We experienced a case with the rate-dependent elevation of the capture threshold following the implantation of a leadless pacemaker. The recognition of the rate-dependency of the capture threshold and the acceptable programming could avoid the unnecessary recapture and reimplantation of that, avoiding the increase of procedural risks...

Debranching thoracic endovascular aortic repair may disturb the implantation of a cardiac implantable electronic device in the anterior thoracic region. In case 1, the bypass graft between the right axillary artery, left axillary artery, and left common carotid artery disturbed pacemaker implantation from the left anterior thoracic region. Therefore, right-sided implantation was selected. By contrast, in case 2, the bypass graft between axillary arteries in the anterior thoracic region was visible on fluoroscopy, and we performed conventional left-sided pacemaker implantation with extra-thoracic puncture...
