Convergent procedure for long-standing persistent atrial fibrillation in heart failure with reduced ejection fraction.
Arch Cardiovasc Dis
December 2024
Service de cardiologie, hôpital Henri-Mondor, 94000 Créteil, France. Electronic address:
Background: Catheter ablation for atrial fibrillation in patients with heart failure with reduced ejection fraction is associated with a significant reduction in morbimortality. The convergent procedure is a valid ablation option for the treatment of long-standing persistent atrial fibrillation.
Aim: To describe the outcomes of patients with heart failure with reduced ejection fraction and long-standing persistent atrial fibrillation who underwent the convergent procedure.
Case Report: The unrelenting journey-successful resolution of catecholaminergic polymorphic ventricular tachycardia (CPVT) through right cardiac sympathetic denervation in a teenager after left cardiac sympathetic denervation.
Front Cardiovasc Med
December 2024
Department of Paediatrics and Adolescent Medicine, The University of Hong Kong, Pok Fu Lam, Hong Kong SAR, China.
Background: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare inherited arrhythmia disorder characterized by ventricular arrhythmia triggered by adrenergic stimulation.
Case Presentation: A 9-year-old boy presented with convulsions following physical exertion. Bidirectional ventricular tachycardia (VT) during a treadmill test led to the diagnosis of catecholaminergic polymorphic ventricular tachycardia (CPVT).
High-Power Short-Duration Radiofrequency Application for Faster and Safer Pulmonary Vein Isolation: The POWER-FAST III Trial.
JACC Clin Electrophysiol
November 2024
Arrhythmia and Robotic EP Unit, Cardiology Department, Hospital Universitario La Paz, IdiPAZ, Madrid, Spain. Electronic address:
Background: The optimal radiofrequency application (RFa) parameters for safe and durable pulmonary vein isolation (PVI) are debated. High-power short-duration (HPSD) has been used as an alternative to conventional power delivery (CPD).
Objectives: This study sought to compare HPSD 70 W/9-10 s (HPSD-70) with CPD 25-40 W in patients undergoing PVI.
Outcomes of Del Nido and hyperkalemic blood cardioplegia in adult cardiac surgery with prolonged aortic cross-clamp times★.
J Extra Corpor Technol
December 2024
College of Medicine and Public Health, Flinders University - Quality and Outcomes Unit, Cardiothoracic Surgical Unit, Division of Surgery, Flinders Medical Centre, Adelaide, South Australia, Australia.
Background: The utility and uptake of Del Nido cardioplegia in adult cardiac surgery is rapidly increasing. Cases with prolonged aortic cross-clamp times necessitate multi-dosing however an understanding of safe ischaemic times and definitive guidelines in this domain are lacking. Therefore, this study aimed to assess the safety and efficacy of our DNC strategy by comparing post-operative troponin profiles and clinical outcomes between Del Nido and hyperkalaemic cardioplegia for cases with aortic cross-clamp times of greater than 90 min.

Clin Med (Lond)
December 2024
Department of Cardiology, Barts Heart Centre and Newham University Hospital, Barts Health NHS Trust, Honorary Senior Lecturer, William Harvey Research Institute, Queen Mary University of London. Electronic address:
Palpitations are common in pregnancy and warrant investigation. Palpitations may be caused by non-cardiac and cardiac causes. Patients with structural or functional abnormalities or inherited cardiovascular disease are more likely to develop arrhythmia, especially during pregnancy when the mother's body undergoes extensive physiological adaptations, which further contribute to an increased arrhythmia risk.
