Why the study?
Preexcitation cardiomyopathy is a rare and potentially life-threatening anomaly, and echocardiography plays an important role in identifying its characteristic findings.
Echocardiography can identify preexcitation cardiomyopathy via the 'rebounce' movement of the inter-ventricular septum, and patients can recover following radiofrequency catheter ablation.
May support ablation consideration in rare pediatric cases; leaves open validation in prospective studies.
Preexcitation cardiomyopathy is a rare cardiac anomaly but it can be life threatening. It may occur in type B preexcitation syndrome. A patients with this condition typically has an enlarged left ventricle and reduced systolic function without tachycardia-associated cardiomyopathy. Echocardiography plays an important role in diagnosis in identifying this condition by revealing the "rebounce" movement of the inter-ventricular septum (IVS). We report echocardiographic findings of five pediatric patients with preexcitation cardiomyopathy. All of them had a radiofrequency catheter ablation (RFCA) and recovered during the follow-up.
