In childhood, a disorder which involves both the heart and lungs problems, called Pediatric Cardiopulmonary disease. Epicardial adipose tissue (EAT) is the visceral fat deposit around the heart and is commonly increased in obese subjects.

Narrowing is usually caused by arteriosclerosis. We will be discussed more about the common problem of the baby heart diseases as Cardiomyopathy, Myocarditis,, Hypoplastic Left Heart Syndrome, Hypertension, Heart Murmur, Cardiac Arrest, Pericarditis Effusion, Arrhythmogenic Right Ventricular Dysplasia, Cyanotic Heart Disease, and Pediatric Arrhythmia.
