Case Report and Literature Review: Infant Heart Hemangiomas Combined with Congenital Heart Defects and Arrhythmias

Cardiac hemangiomas (CHs) can manifest at any age with an exceedingly low incidence among the infant population. Despite their benign nature, CHs can lead to serious complications, including murmurs, cyanosis, arrhythmia, heart failure, hydrops fetalis, or fetal death. While echocardiography provides real-time assessment, CHs may mimic other cardiac abnormalities, necessitating further imaging modalities such as CT or MRI for accurate diagnosis. Treatment typically involves radical resection, even in asymptomatic cases, and propranolol has shown promise in combination with surgical resection. We describe two cases of cardiac hemangiomas in the atrium along with congenital heart defects, one of whom developed a second-degree atrioventricular block post-resection.
