Arrhythmia Classification Using Graph Neural Networks Based on Correlation Matrix [PDF]

arXiv
With the advancements in graph neural network, there has been increasing interest in applying this network to ECG signal analysis. In this study, we generated an adjacency matrix using correlation matrix of extracted features and applied a graph neural network to classify arrhythmias.

Steerable Delivery Sheath for Optimized LAA Closure: First Experience and Procedural Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease‐of‐use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control ...

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Incidence and 1‐Year Prognostic of Unstable Angina After High‐Sensitivity Troponin Assessment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Incidence and prognostic of unstable angina after high‐sensitivity troponin assesment is controversial. Aims This study evaluated prognostic of a contemporary population of patients with UA defined using high sensitive T troponin (T hs‐cTn) measurements and with significant coronary artery disease (CAD). Methods Consecutive patients

Safety and Efficacy of Single Femoral Vein Puncture Technique for Double Access in Patent Foramen Ovale Closure Under ICE Guidance—A Single Center Experience of the “Two‐In‐One Technique”

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In selected patient populations, percutaneous closure of patent foramen ovale has been shown to be beneficial in preventing cerebral ischaemic events. In most cases, this procedure requires echocardiographic guidance, which may be transesophageal, transthoracic or intracardiac.
