This chapter describes structural abnormalities of heart/valvular heart disease. Proper cardiac valve function is essential for uninterrupted blood flow through the heart. These valves ensure one-way blood flow through and out of the heart. Valvular heart disease interferes with blood flow to and from the heart. This chapter covers the mitral valve disease, aortic valve disease, tricuspid valve disease, and community-based care. Mitral valve separate left atrium from left ventricle, the leaflets of the atrioventricular valves are connected to ventricular papillary muscles fibrous by chordae tendineae. Chordae tendineae prevent bulging of ventricular leaflet back into the atria during systole. The disorders of the mitral valve are mitral stenosis (MS), mitral regurgitation (MR) and mitral valve prolapse (MVP). Tricuspid valve disorders (TVD) usually develop in combination with other structural defect of heart. Tricuspid stenosis and regurgitation are the common disorder seen in tricuspid valve conditions.
