Both doctors say that signs and symptoms of valve damage can vary, but the main ones to be aware of are shortness of breath (particularly during exercise or any form of exertion) and chest pain or ...
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 ...
Adding a rigid prosthetic ring aims to decrease the diameter of the valve and stabilize it. Another annuloplasty modality is the "De Vega technique", in which the valve diameter is decreased by two sutures placed around the periphery of the valve. In cases of severe organic lesions of the valve, such as endocarditis, the valve may be excised.
Aortic stenosis is most commonly caused by age-related progressive calcific aortic valve disease (CAVD) (>50% of cases), with a mean age of 65 to 70 years. CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. [22]
Infective endocarditis is an infection of the inner surface of the heart (endocardium), usually the valves. [1] Signs and symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cell count.
Mitral regurgitation, also known as mitral insufficiency or mitral incompetence, is the backward flow of blood from the left ventricle, through the mitral valve, and into the left atrium, when the left ventricle contracts, resulting in a systolic murmur radiating to the left armpit.

When the mitral valve area goes less than 1 cm 2, there will be an increase in the left atrial pressures (required to push blood through the stenotic valve). Since the normal left ventricular diastolic pressures is about 5 mmHg, a pressure gradient across the mitral valve of 20 mmHg due to severe mitral stenosis will cause a left atrial ...
