Intrapericardial Corticosteroids and Colchicine Prevent Pericarditis and Atrial Fibrillation After Epicardial Ablation of Ventricular Arrhythmias.
JACC Clin Electrophysiol
January 2025
Cardiac Arrhythmia Service, Cardiovascular Division, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.
Background: Postprocedural pericarditis (PP) can occur in up to 29.4% of patients undergoing epicardial catheter ablation of ventricular tachycardia (VT). Despite several proposed strategies to mitigate this adverse outcome, rates of PP and pericarditic pain remain high.

Background: Earlier studies have documented the risk for sinoatrial node injury and phrenic nerve paralysis as complications following radiofrequency catheter ablation for electrical isolation of the superior vena cava (SVCI).
Objectives: The aim of this study was to assess the safety and feasibility of SVCI in patients with atrial fibrillation undergoing pulsed field ablation (PFA) METHODS: Six hundred sixteen consecutive patients undergoing PFA for pulmonary vein isolation plus SVCI were included in this multicenter analysis. Superior vena cava (SVC) ablation was performed under the continuous guidance of intracardiac echocardiography.
Multipath joint ablation strategy for focal atrial tachycardia originating from patent foramen ovale: a case report.
Front Cardiovasc Med
January 2025
Key Laboratory of Birth Defects and Related Diseases of Women and Children of MOE, Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, China.
Introduction: Focal atrial tachycardia (FAT) is predominant in the pediatric population. Recent research has identified cases of sustained FAT originating from the interatrial septum (IAS); a subset of cases presents a unique challenge, with foci originating from the peri-patent foramen ovale (peri-PFO), requiring specialized management during catheter ablation. Here, we present a rare case of peri-PFO-associated FAT that resulted in tachycardia-related cardiomyopathy and propose a comprehensive multipath joint strategy for the successful treatment of PFO-associated FAT.

Aix-Marseille Univ, CNRS, CRMBM, Marseille, France; APHM, Hôpital Universitaire Timone, CEMEREM, Marseille, France; Department of Radiology, Lausanne University Hospital and University of Lausanne, Lausanne, Switzerland.
Purpose: To develop an improved post-processing pipeline for noise-robust accelerated phase-cycled Cartesian Single (SQ) and Triple Quantum (TQ) sodium (Na) Magnetic Resonance Imaging (MRI) of in vivo human brain at 7 T.
Theory And Methods: Our pipeline aims to tackle the challenges of Na Multi-Quantum Coherences (MQC) MRI including low Signal-to-Noise Ratio (SNR) and time-consuming Radiofrequency (RF) phase-cycling. Our method combines low-rank k-space denoising for SNR enhancement with Dynamic Mode Decomposition (DMD) to robustly separate SQ and TQ signal components.
Comparison of radiofrequency ablation, microwave ablation and high-intensity focused ultrasound for hepatocellular carcinoma: a retrospective study.

Background: The recommended first-line treatment for respectable hepatocellular carcinoma (HCC) is surgical resection, but local ablation has gained popularity as a safe alternative. This study aims to compare the effectiveness of radiofrequency ablation (RFA), microwave ablation (MWA) and high-intensity focused ultrasound (HIFU) as first-line treatments for HCC.
Methods: In this single-centre retrospective study, 352 patients receiving RFA, MWA, or HIFU as first-line treatment for HCC were included.
