Article Synopsis
- The study investigates the effectiveness and safety of pulsed field ablation (PFA) for treating atrial fibrillation (AF) in Asia, specifically focusing on its use for pulmonary vein isolation (PVI) and optional posterior wall ablation (PWA).
- A total of 101 AF patients were analyzed, revealing a 1-year atrial arrhythmia recurrence rate of 10% for paroxysmal AF and 21% for persistent AF, with no significant differences in efficacy between PVI-only and PVI + PWA approaches.
- The research concludes that PFA is a safe and effective method for AF ablation, with the additional PWA not leading to increased complications while maintaining procedural efficiency.*
Article Synopsis
- Catheter ablation is an effective treatment for supraventricular tachycardia (SVT), and this study investigates the impact of 3D-electroanatomic mapping (EAM) on fluoroscopy time during the procedure.
- Over 1750 SVT ablation cases were analyzed, finding that EAM leads to longer procedure times but significantly reduces fluoroscopy time (by about 20 minutes) and radiation exposure without increasing complications.
- The study noted that while fluoroscopy time decreased initially, this reduction plateaued after several years, suggesting that more experience with the technique may influence efficiency in complex cases.
Background: Atrial fibrillation (AF) is a cause of serious morbidity such as stroke. Early detection and treatment of AF is important. Current guidelines recommend screening via opportunistic pulse taking or 12‑lead electrocardiogram.

- Palpitations are a frequent side effect after receiving mRNA COVID-19 vaccines, although they can vary in severity.
- Some individuals may experience more intense symptoms that warrant additional medical evaluation.
- A notable case involved a healthy man who had significant palpitations and an increased heart rate following both doses of the Pfizer/BioNTech vaccine, highlighting the need for further investigation.
Article Synopsis
- * A total of 22 patients, primarily elderly males with a mean age of 71.7 years, underwent the LBBP procedure, achieving an 86% success rate in lead implantation without major complications.
- * The findings indicate that the Agilis HisPro™ catheter, paired with the Tendril STS Model 2088TC lead, is a promising and safe method for performing LBBP.
Advanced cardiac life support (ACLS) emphasises the use of advanced airway management and ventilation, circulatory support and the appropriate use of drugs in resuscitation, as well as the identification of reversible causes of cardiac arrest. Extracorporeal cardiopulmonary resuscitation and organ donation, as well as special circumstances including drowning, pulmonary embolism and pregnancy are addressed. Resuscitation does not end with ACLS but must continue in post-resuscitation care.

Genetic testing offers a means to clinically assess and manage affected individuals and their family members.
Methods And Results: The proband at age 44 years old exhibited a syncopal event during exercise, and presented later with a spontaneous type-I BrS pattern on 12‑lead resting electrocardiogram (ECG).
Article Synopsis
- Remote Controlled Magnetic Navigation (RMN) for atrial fibrillation ablation reduces fluoroscopy time significantly compared to traditional Manual (MAN) techniques, but results in a longer overall procedural duration.
- In a study involving 214 RMN patients and 229 MAN patients, fluoroscopy times were shorter for RMN (53.5 min) while procedural times were longer (280.2 min), highlighting a trade-off between these two factors.
- Despite differences in timing, both techniques showed similar rates of acute procedural success (98.6% for RMN vs. 95.6% for MAN) and complication rates (2.3% for RMN vs. 4.8% for MAN), suggesting RMN is
Introduction: Remote monitoring of cardiac implantable electronic devices (CIED) has been shown to improve patient safety and reduce in-office visits. We report our experience with remote monitoring via the Medtronic CareLink(®) network.
Methods: Patients were followed up for six months with scheduled monthly remote monitoring transmissions in addition to routine in-office checks.
Article Synopsis
- Brugada syndrome (BrS) is a rare hereditary heart condition often linked to mutations in the SCN5A gene, which plays a critical role in sodium ion channel function; it is responsible for 15-30% of cases.
- A young male proband experienced syncopal episodes and was found to carry two mutations in the SCN5A gene inherited from his parents, leading to significant abnormalities during stress testing and a high risk for dangerous heart rhythms.
- This study highlights the unique presentation of compound heterozygote mutations in a Singaporean Chinese family, suggesting variations in how BrS manifests in different populations.
Ablation of sinus node reentrant tachycardia (SNRT) may be difficult with risk of sinus node injury by using conventional catheters. We report successful ablation of SNRT by using remote magnetic navigation system (Stereotaxis).
