Other etiologies such as infective endocarditis, mitral annular calcification in elderly patients, congenital malformation (parachute mitral valve), systemic lupus erythematosis, carcinoid heart disease, endomyocardial fibrosis and rheumatoid arteritis are representing less than 10% of adult cases. Etiology of MS in adult patients in the great majority of cases (more than 90%) is the rheumatic involvement of the mitral valve.

Mitral stenosis consists of 12% of all valvular heart disease in Euro Heart Survey. All measurements of the 2D TEE and the RT-3D-FV dataset (Qlab) were performed offline by two independent examiners. QLab 3 Show Control: Projects for Live Performances & Installations is a project-based book on QLab software covering sound, video, and show control. Students will have ample opportunity to develop hands-on experience. This rise in the left atrial pressure is then transmitted to the pulmonary vasculature and causes pulmonary hypertension and eventually pulmonary congestion and edema. On the second day, the Philips ultrasound clinical education team will assist in instructing participants on optimizing acquisition, manipulation, cropping, and quantification of 3D TEE data sets using QLAB software. When the mitral valve area becomes less than 1 cm 2, there will be an increase in the left atrial pressure to overcome the valve gradient. This gradient may increase by the rise in heart rate or cardiac output.

The normal area of the mitral valve orifice is about 4–6 cm 2 when the mitral valve area goes below 2 cm 2, the valve causes an impediment to the flow of blood into the left ventricle, creating a pressure gradient across the mitral valve.

Obstruction happens due to thickening and immobility of the leaflets, thickening and fusion of the chorda tendinae or mitral annular and commissural calcification. Mitral stenosis (MS) is a mechanical obstruction in blood flow from the left atrium to the left ventricle. This flow direction will be maintained as long as the pressure in the left ventricle is lower than the pressure in the left atrium and the blood flows down the pressure gradient. In normal cardiac physiology, the mitral valve opens during left ventricular diastole, to allow blood to flow from the left atrium to the left ventricle.
