Takotsubo cardiomyopathy (broken heart syndrome) mimics heart attack symptoms but causes no actual blockages. It's often related to severe stress or trauma.
In tricuspid atresia, the tricuspid valve, which is between the heart’s upper right (right atrium) and lower right (right ventricle) chambers, doesn’t develop.
Tricuspid valve stenosis is a narrowing of the tricuspid valve that causes an obstruction of blood flow between the heart's right atrium and right ventricle.
In truncus arteriosus, a single blood vessel emerges from the heart, failing to completely separate into two vessels normally: a pulmonary artery and an aorta.
A vascular ring is when there's an abnormal formation of the main artery delivering blood from the heart to the body (aorta) and its associated blood vessels.
Venous disease (leg vein problems), such as blood clots and weak or damaged veins, can interfere with the crucial role of veins in the cardiovascular system.
