AI Article Synopsis
- Ablation of premature ventricular contractions (PVCs) typically requires detailed activation mapping, but this can be challenging if PVCs are absent during the procedure.
- An alternative method, pacemapping, has its drawbacks.
- In a case study, a patient with frequent PVCs had no PVCs on the procedure day, yet successful ablation was achieved using electrocardiographic imaging and substrate mapping.
Article Abstract
Ablation of premature ventricular contractions (PVCs), relies mostly on a detailed activation mapping. This can be impossible to achieve in case of paucity or even absence of PVCs during the procedure. Pacemapping as an alternative has many limitations. We present a case of a patient with very frequent symptomatic PVCs, that on the day of the procedure had total absence of PVCs. We performed successful ablation based exclusively on electrocardiographic imaging confirmed by substrate mapping.

Article Synopsis
- The study explores the management and diagnosis of Wolf-Parkinson White Syndrome (WPW) and asymptomatic pre-excitation in Africa, highlighting a lack of data in the region.
- Conducted in 20 centers across 17 African countries, the research involved 541 participants and focused on symptomatology, treatment approaches, and the impact of local health dynamics on care.
- Results indicated that a vast majority were diagnosed with WPW, with significant regional differences in treatment options and effectiveness, showing that Northern and Southern Africa have more advanced practices compared to other areas.
Typical Atrial Flutter: A Practical Review.
J Cardiovasc Electrophysiol
January 2025
Cardiology Division, Geneva University Hospitals, Geneva, Switzerland.
Typical atrial flutter (AFL), defined as cavotricuspid isthmus (CTI)-dependent macro-re-entrant atrial tachycardia, often causes debilitating symptoms, and is associated with increased incidence of atrial fibrillation, stroke, heart failure, and death. Typical AFL occurs in patients with atrial remodeling and shares risk factors with atrial fibrillation. It is also common in patients with a history of prior heart surgery or catheter ablation.

They are difficult to study, as interfering with their function leads to premature death. Transcription is one of the essential functions of life, and the multi-protein Mediator complex coordinates the regulation of gene expression at nearly every eukaryotic promoter.

Background: Transarterial chemoembolization (TACE) is an effective and safe downstaging therapy for hepatocellular carcinoma (HCC). However, the selection of sequential therapeutic modalities is still controversial.
Objectives: This study compared the effectiveness and safety of surgical resection (SR) and thermal ablation (TA) after patients with HCC underwent TACE downstaging therapy.
Nonocclusive Ablation Technique Using a Novel Cryoballoon for Failed Left Superior Pulmonary Vein Isolation Despite Complete Occlusion.
Pacing Clin Electrophysiol
January 2025
Department of Cardiovascular Medicine, Institute of Science Tokyo, Bunkyo-ku, Tokyo, Japan.
Article Synopsis
- This study examines factors influencing the failure of left superior pulmonary vein (LSPV) isolation during cryoballoon (CB) procedure, even when complete occlusion is achieved.
- Researchers analyzed 300 patients undergoing ablation, identifying two groups based on their LSPV isolation results: those needing additional freezing (Group A) and those only needing complete occlusion (Group B).
- Key findings show that Group A had larger LSPV diameters, higher left atrial volumes, and different freezing conditions, suggesting the importance of balloon positioning for effective isolation in challenging cases.
