Also called aortic valve disease, aortic valvular disease refers to any condition that causes narrowing (stenosis), leaking (regurgitation) or other issues with the heart's aortic valve. Located between the heart's main pumping chamber (the left ventricle) and the aorta -- the body's largest artery, which carries oxygenated blood away from the heart -- the aortic valve normally ensures one-way blood flow from the heart to the body.

Conduction disorders are problems with the heart's electrical system that can disrupt the signals between the upper and lower chambers of the heart. That can potentially cause issues like an irregular heartbeat (arrhythmia) or slow heart rate.

Congenital heart anomalies are abnormal issues with the heart's structure that occur as the heart forms in the womb. If these issues are serious, they can impact blood flow, potentially causing symptoms like fatigue, shortness of breath or even heart failure -- a condition in which the heart isn't able to pump enough blood to meet the body's needs. Many congenital heart anomalies are mild and cause no symptoms. However, some are more severe and may require treatment, potentially including surgic
