Kawasaki disease (KD) is an acute vasculitis involving all blood vessels with frequent cardiovascular complications. We describe a 28-year-old patient with childhood KD having coronary complications at the age of 17 now presenting with sustained atrial tachycardia. Electrophysiological study and catheter ablation were performed. Electrophysiological study revealed a left atrial (LA) tachycardia (230 ms cycle length) with 2:1 atrioventricular node conduction. The mechanism for the arrhythmia was re-entry around the mitral annulus associated with the low-voltage scar area anterolateral to the annulus and juxtaproximal to the coronary artery calcification seen in fluoroscopy. We describe a patient with childhood KD presenting with LA re-entrant tachycardia associated with the atrial scar. The arrhythmia was successfully treated using radiofrequency catheter ablation.

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.

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.

Background: Early left ventricular systolic dysfunction is common after moderate-severe traumatic brain injury (TBI). Echocardiography (Echo) can evaluate cardiac function across various clinical scenarios; however, its utilization in isolated TBI remains poorly understood. To address this gap, we aim to examine Echo utilization in hospitalized adults with isolated TBI.

Background: Supraventricular tachycardia (SVT) is very common in daily clinical practice, especially in the emergency department, with rapid onset and urgent management. The review highlights the recent genetic predispositions and mechanisms in SVT.
Methods: Through analysis of epidemiology, familial clustering, and gene mutations of the relevant literature，the review elucidates the genetic properties and potential pathophysiology of SVT.

Purpose Of Review: This paper reviewed the current literature on incidence, clinical manifestations, and risk factors of Chimeric Antigen Receptor T-cell (CAR-T) cardiotoxicity.
Recent Findings: CAR-T therapy has emerged as a groundbreaking treatment for hematological malignancies since FDA approval in 2017. CAR-T therapy is however associated with a few side effects, among which cardiotoxicity is of significant concern.
