Heart & Cardiovascular System

Hypertension (High Blood Pressure)
About 1 in 5 Americans has high blood pressure. Although it's more common in adults, hypertension can occur at any age.

Coarctation of the Aorta
When someone has coarctation of the aorta, that person's aorta (the major blood vessel that carries blood away from the heart to the body) is narrowed at some point.

Ventricular Septal Defect
Ventricular septal defect, or VSD, is a heart condition that a few teens can have. Find out what it is, how it happens, and what doctors do to correct it.

Atrial Septal Defect
Atrial septal defect, or ASD, is a heart condition that teens can have. In most cases, ASDs are diagnosed and treated successfully with few or no complications.

Arrhythmias are abnormal heartbeats usually caused by an electrical "short circuit" in the heart. Many are minor and not a significant health threat, but others can indicate a more serious problem.
