Impact of leadless pacemaker implantation site on cardiac synchronization and tricuspid regurgitation.
Egypt Heart J
January 2025
Department of Cardiology, Hangzhou First People's Hospital, #261 Huansha Road, Hangzhou, 310000, Zhejiang Province, China.
Background: To investigate the optimization of leadless pacemaker placement and to assess its impact on heart synchronization and tricuspid regurgitation.
Results: A clinical trial was conducted involving 53 patients who underwent leadless pacemaker implantation at the Second Affiliated Hospital of Zhejiang University School of Medicine and Hangzhou First People's Hospital between March 2022 and February 2023. Implantation site localization was determined using the 18-segment method under RAO 30° imaging.
Novel use of trametinib for treatment of atrial arrhythmia in absence of cardiomyopathy in a patient with Costello syndrome.

We describe a case of novel use of trametinib in treating arrythmia without concomitant cardiomyopathy. Our patient is a two-year-old female born with Costello syndrome due to heterozygous mutations in the HRAS gene c34 G > T p (G12C). Shortly after birth, she was diagnosed with multifocal atrial tachyarrhythmia.

AF is a common arrhythmia in cardiomyopathy, particularly when congestive heart failure is present. The neurohormonal activation in congestive heart failure may trigger fibrotic and other changes in the left atrium and the atrial stretch associated with heart failure may induce further atrial pathology and/ or directly trigger AF (8). By the time that patients with AF develop extensive fibrosis, the arrhythmia has been shown to be associated with a greater difficulty in maintaining sinus rhythm despite attempted ablation procedures.

Introduction/objective: Atrial fibrillation (AF) could present with slow ventricular-response; bradycardia could facilitate the emergence of AF. The conviction that one "does not succumb" from bradycardia as an escape rhythm will emerge unless one sustains a fatal injury following syncope is in stark difference with ventricular tachyarrhythmia (VA), which may promptly cause cardiac arrest. However, this is not always the case, as a life-threatening situation may emerge during the bradycardic episode, i.

General Practice Ward/International Medical Center Ward, General Practice Medical Center, West China Hospital, Sichuan University, Chengdu, China.
Background And Aims: Cirrhosis is characterised by hyperdynamic circulation, which contributes to cirrhotic cardiomyopathy (CCM). However, the expert consensus on CCM did not initially include cardiac structure because of scant evidence. Therefore, this study investigated the associations of cardiac chamber geometry with mortality and CCM.
