AI Article Synopsis
- A case study of a 14-year-old boy with persistent atrial tachycardia emerging from the right atrial appendage and showing early signs of left ventricular dysfunction was presented.
- The electrocardiogram revealed specific P-wave patterns indicating the location of the tachycardia.
- A first ablation attempt failed due to inadequate cooling, but a second attempt utilizing advanced technology successfully resolved the issue.
Article Abstract
We present a case of 14-year-old boy with incessant atrial tachycardia from right atrial appendage, resistant to pharmacotherapy and with early signs of the left ventricle tachyarrhythmic dysfunction. The P-wave was positive in leads I, II, III, aVF, negative in aVR, aVL. Moreover, P waves configuration specific for this localization: negative in V1-V2 that become positive in V3-V6 was present. After first ablation session a recurrence was observed after 3 weeks, due to inadequate power delivery resulting from trabeculation/anatomy that limited conventional ablation catheter cooling. Second ablation session with the use of an active electrode cooling and 3D mapping system was successful.

Background: Andersen-Tawil syndrome (ATS) is a rare autosomal dominant disorder caused by variants in the gene. It is associated with periodic paralysis, dysmorphic features and cardiac arrhythmias. The syndrome exhibits incomplete penetrance, leading to a broad spectrum of clinical manifestations, making diagnosis challenging.

Background And Objectives: Cardiovascular Diseases (CVDs), including Acute Coronary Syndrome (ACS), represent a major global health challenge. Arrhythmias such as Ventricular Tachycardia (VT), Ventricular Fibrillation (VF), Atrial Fibrillation (AF), Premature Ventricular Contractions (PVCs), and Premature Atrial Contractions (PACs) frequently complicate ACS, needing effective management strategies. Omega-3 fatty acids have shown potency in preventing sudden cardiac death by modulating arrhythmias, but their acute effects in ACS patients remain controversial.

Background: Ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) can lead to sudden cardiac death. The role of ventricular tachycardia ablation (VTA) in CS has been investigated in a few small, single-center, and larger observational studies, but the evidence still needs to be provided. This study aimed to investigate the clinical outcomes of VTA in patients with CS admitted with a diagnosis of VT.

Objective: To describe the outcome of a case of severe drug-resistant fetal tachyarrhythmia with progressive hydrops treated with fetoscopic transesophageal pacing (FTEP).
Method: A case of fetal tachyarrhythmia complicated by progressive hydrops is presented. The fetus, diagnosed at 26 weeks of gestation, had supraventricular tachycardia with a mechanism suggestive of atrial reentry.
