A quadricuspid aortic valve (QAV) is a rare congenital heart defect characterized by the presence of four cusps, instead of the usual three found normally in the aortic valve. [1] It is a defect that occurs during embryological development of the aortic trunk during gestation . [ 2 ]
Today, cardiovascular symptoms of Marfan syndrome are still the most significant issues in diagnosis and management of the disease, but adequate prophylactic monitoring and prophylactic therapy offers something approaching a normal lifespan, and more manifestations of the disease are being discovered as more patients live longer.

Many people with early coronary artery disease don’t have any symptoms. If your heart doesn’t get enough oxygen, you might develop chest pain (angina). When the blood flow to your heart is ...
Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...
Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
Pulmonary valve diseases are the least common heart valve disease in adults. [1] [4] Pulmonary valve stenosis is often the result of congenital malformations and is observed in isolation or as part of a larger pathologic process, as in Tetralogy of Fallot, Noonan syndrome, and congenital rubella syndrome. Unless the degree of stenosis is severe ...
Frenneaux’s team examined 4,237 healthy, symptom-free UK residents 60 and older. 28% had some form of heart valve disease — most of the cases were mild.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal. [4]
