Peripheral artery disease (PAD) is a disease in which plaque builds up in the arteries that carry blood to your head, organs, and limbs. When plaque builds up in the body's arteries, the condition is called atherosclerosis. Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body.

A pulmonary embolism is an obstruction caused by a blood clot (thrombus) in the pulmonary artery that has traveled through the bloodstream (usually from a vein in the legs).


Pulmonary fibrosis is a condition in which there is scarring of the tissue in the lungs. This tissue gets thick and stiff. That makes it hard for you to breathe, and your blood may not get enough oxygen.


Pulmonary hypertension (PH) is a type of coronary artery disease (CAD). This condition occurs when the pressure in the pulmonary arteries becomes abnormally elevated. There is inflammation in the lining of the pulmonary artery, which changes the cells in the lining, making it more difficult for the heart to pump blood forward into the lungs to be oxygenated.


Pulmonary valve regurgitation, also known as valve insufficiency, occurs when the heart’s pulmonary valve does not close properly, allowing some blood to leak back into the heart chamber before it flows into the lungs to be oxygenated...


Over time, the opening in a heart valve can become narrow due to a collection of calcium deposits. When the valve narrows, the heart does not pump as well. Valvular stenosis can affect the heart's aortic, mitral, pulmonary or tricuspid valves.
