Percutaneous VT Ablation via RA-to-LV Access in Patients With Double Mechanical Valves: A Multicenter Registry.

Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.

Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.

Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.

Clinical Impact of Pancreatic and Peripancreatic Hemorrhage Associated With Acute Pancreatitis.

Purpose: The significance of pancreatitis-associated hemorrhage outside the context of a ruptured pseudoaneurysm remains unclear. This study aims to characterize the clinical significance of pancreatic hemorrhage during acute pancreatitis (AP).

Methods: This retrospective study included adult patients diagnosed with hemorrhagic pancreatitis (HP) from 2010 to 2021.

Identifying the presence of atrial fibrillation during sinus rhythm using a dual-input mixed neural network with ECG coloring technology.

Background: Undetected atrial fibrillation (AF) poses a significant risk of stroke and cardiovascular mortality. However, diagnosing AF in real-time can be challenging as the arrhythmia is often not captured instantly. To address this issue, a deep-learning model was developed to diagnose AF even during periods of arrhythmia-free windows.

Performance of the novel ANTWERP score in predicting heart function improvement after atrial fibrillation ablation in Asian patients with heart failure.

Background: Previous research has demonstrated that atrial fibrillation (AF) ablation improves heart function variably among patients. We proposed that the ANTWERP score, which was validated in a European group of patients with low left ventricular ejection fraction (LVEF) who had AF ablation, would be valid in an Asian group as well. The purpose of the study is to examine how well a new scoring system (the ANTWERP score) can predict heart function improvement after atrial fibrillation ablation in Asian patients with heart failure.
