A new HCM heart sound classification method based on weighted bispectrum features.

Phys Eng Sci Med

January 2025

School of Electrical Engineering and Electronic Information, Xihua University, Chengdu, China.

Hypertrophic cardiomyopathy (HCM), including obstructive HCM and non-obstructive HCM, can lead to sudden cardiac arrest in adolescents and athletes. Early diagnosis and treatment through auscultation of different types of HCM can prevent the occurrence of malignant events. However, it is challenging to distinguish the pathological information of HCM related to differential left ventricular outflow tract pressure gradients.

Management Strategies for Truncus Arteriosus: A Comparative Analysis of Staged vs. Primary Repair.

Pediatr Cardiol

January 2025

Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences and Okayama University Hospital, 2-5-1 Shikatacho, Kitaku, Okayama, Japan.

We reviewed the outcomes of truncus arteriosus repair (primary vs. staged repair incorporating bilateral pulmonary artery banding), focusing on survival, reintervention, and functional data. We analyzed 39 patients who underwent a first intervention for truncus arteriosus (staged, n = 19; primary, n = 20) between 1992 and 2022.

[Catheter ablation in patients with heart failure-who benefits?].

Herzschrittmacherther Elektrophysiol

January 2025

Klinik für Elektrophysiologie/Rhythmologie, Ruhr-Universität Bochum, Bochum, Deutschland.

Atrial fibrillation (AF) ablation is associated with a lower likelihood of death and surgical heart failure (HF) interventions in patients with HF. This effect is mainly driven by reduced all cause and cardiovascular death following ablation. Ablation also results in improved left ventricular (LV) function, decreased AF burden and AF regression.

BACKGROUND: Changes in pupil reactivity secondary to cerebral mass effect are traditionally linked to compression of the oculomotor nerve by the uncus or by horizontal midbrain displacement. The neurological pupil index (NPi) is a metric to assess the pupillary light reflex. This study explores the relationship of midline shift, cisternal, and sulcal effacement or ventricular compression in patients with a new finding of abnormal pupillary light reflex.

Background: Implantable cardioverter-defibrillators (ICDs) are essential for reducing sudden cardiac death in patients at risk of ventricular arrhythmias. The choice of ICD lead - single-coil or dual-coil - can influence device performance and patient outcomes. This meta-analysis evaluates the comparative efficacy and safety of single-coil versus dual-coil ICD leads to inform clinical decision-making.
