Abstract

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.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Electrophysiology

Cardiac electrophysiology is the study of electrical activities of the heart and includes the assessment, diagnosis, and treatment of cardiac events. Find the latest research on cardiac electrophysiology here.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.
