A 38-year-old man was admitted to our hospital after ventricular tachycardia. Endocardial bipolar and unipolar voltage mapping were performed and findings were integrated with data from intracardiac echocardiography (ICE) right ventricular (RV) speckle-tracking analysis. A reduction in the strain analysis was stored in correspondence of the fragmented electrogram area.

- Catheter ablation (CA) is an effective treatment for atrial flutter, and this study focused on enhancing CA for the cavotricuspid isthmus (CTI) using a zero-fluoroscopy (ZF) technique.
- A total of 188 patients were divided into two groups: one used a standard catheter without shaft visualization (Group 1), while the other utilized a shaft visualization approach (Group 2).
- The results indicated that the ZF method allowed for a complete CTI block with reduced radiofrequency duration and shorter procedure times in Group 2, demonstrating that shaft visualization aids in safer catheter manipulation and effective treatment outcomes.
Aims: The aim of this study is to report heart failure hospitalization (HFH) rates and associated costs within 12 months following implantable cardioverter defibrillator (ICD)/cardiac resynchronization therapy defibrillator (CRT-D) device replacement or upgrade from ICD to CRT-D.
Methods And Results: The DEtect long-term COmplications after icD rEplacement (DECODE) was a prospective, single-arm, multicentre cohort study that explored complications in ICD/CRT-D recipients. All clinical and survival data at 12 months were prospectively analysed.
Detection of oesophageal course during left atrial catheter ablation.

Background: Oesophageal changes and injuries were recorded after atrial fibrillation(AF) ablation procedures. The reduction of power in the posterior left atrial(LA) wall(closest to the oesophagus) and the monitoring of temperature in the oesophagus(OE) reduced oesophageal injuries. The intracardiac-echocardiography(ICE) with a Cartosound module provides two-dimensional imaging (2D) to assess detailed cardiac anatomy and its relationship with the OE.

We designed a nation-wide study aiming to identify clinical and genetic characteristics associated with primary VF; and report here about clinical features.
