The narrowing of the aortic valve opening, restricting blood flow from the left ventricle to the aorta.

An infection of the inner lining of the heart chambers and valves, typically caused by bacteria.

An abnormality in the heart that develops before birth.

A blockage in one of the pulmonary arteries in the lungs, typically caused by blood clots that travel from the legs or other parts of the body.

An irregular heartbeat, where the heart may beat too fast, too slow, or irregularly.

High blood pressure condition, increasing the risk of heart disease, stroke, and kidney problems.

A very common type of arrhythmia where the heart beats irregularly and often rapidly.

A chronic condition where the heart doesn't pump blood as well as it should.

Often called a mini-stroke, a brief period of symptoms similar to those in a stroke, caused by a temporary decrease in blood supply to part of the brain.

When blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients, which can cause brain cells to die.

A hole in the heart, specifically in the ventricular septum, that causes oxygen-rich blood to flow from the left ventricle into the right ventricle, instead of into the aorta and to the body.

Having high levels of cholesterol in the blood, which can increase the risk of atherosclerosis and coronary artery disease.

When one of the coronary arteries arises from an abnormal location or from the wrong coronary sinus, potentially affecting heart function.

Inflammation of the pericardium, the fluid-filled sac surrounding the heart, which causes sharp chest pain.

An enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body, which can cause severe internal bleeding if it ruptures.

A bacterial or fungal infection of the inner lining of the heart or heart valves, often occurring in people with existing heart valve abnormalities.

A condition in which the two valve flaps of the mitral valve do not close smoothly or evenly, but bulge (prolapse) upward into the left atrium.

A hole in the septum between the heart's two upper chambers (atria), which causes mixed blood flow.

An acute, febrile illness of unknown cause that primarily affects children, leading to inflammation within the walls of some blood vessels.

A condition where arteries narrow due to build-up of plaque, potentially leading to coronary artery disease, heart attack, or stroke.

A disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body.

Chest pain caused by reduced blood flow to the heart muscles, often a symptom of coronary artery disease.

Veins that have become enlarged and twisted, commonly found in the legs and feet.

A narrowing of the heart's mitral valve, which obstructs blood flow from the left atrium to the left ventricle.

Occurs when the tricuspid valve fails to close properly, causing blood to flow backward into the right atrium.

A narrowing of the aorta, which constricts the flow of blood through the major artery and can lead to various complications.

Inflammation of a vein caused by a blood clot, which can occur in both superficial and deep veins.

Commonly known as a heart attack, this occurs when blood flow to a part of the heart is blocked, causing tissue damage.

A serious condition in which the inner layer of the aorta, the large blood vessel branching off the heart, tears. Blood surges through the tear, causing the inner and middle layers of the aorta to separate (dissect).

High blood pressure in the arteries to the lungs, which can lead to right heart failure.

A sudden loss of heart function, breathing, and consciousness, often resulting from an electrical disturbance in the heart.

Occurs when the heart's mitral valve doesn't close tightly, allowing blood to flow backward in the heart.

A congenital heart defect that consists of four heart abnormalities that result in insufficiently oxygenated blood pumped to the body.

A circulatory condition in which narrowed arteries reduce blood flow to your limbs, especially legs.

Damage to the heart valves after episodes of rheumatic fever, which is caused by Streptococcus bacteria.

A disorder where blood clots form in the veins, leading to deep vein thrombosis (DVT) or pulmonary embolism (PE).

A condition in which the heart suddenly can't pump enough blood to meet the body's needs, a serious condition often caused by a severe heart attack.

A condition that results from long-standing heart or lung disease, leading to irreversible lung blood vessel changes.
