Mitral valve prolapse

Mitral valve prolapse is condition that the abnormal mitral valve, lead to valvular abnormalities in ventricular systolic and drop into the left atrium. About 1/4 patients have asymptomatic. Non-specific symptoms is repeatedly and transient. More than half patient have chest pain in front heart. That is dull pain, sharp pain or pain like knife cuts, it can be transient, but also sustainable for several hours. Occasionally have typical symptoms of angina pectoris. Mitral valve prolapse often are complicated by mitral valve insufficiency, infective endocarditis, arrhythmias, sudden cardiac death.

Under normal circumstances, ventricular contraction, an immediate contraction of papillary muscles in the tendons of the traction, the mitral valve with each other and the past. When left ventricular systolic ventricular pressure continues to rise, the left atrial valve prolapse, papillary muscle contraction synergy is taut tendons to prevent valgus valve into the left atrium, close valve, close the valve. Valve at this time does not exceed the level of valve ring. When the mitral valve, or chordae tendineae, or papillary muscles, or valve ring lesions occur, the relaxation of the valve leaflets in the valve to close off further to the left atrium, causing mitral insufficiency. Mitral valve prolapse can also be found in left ventricular systolic dysfunction, segmental contraction that will enable the tendons and relaxation in the closure of valve, causing and increase its long, so that in the late systolic heart, occur mitral valve prolapse. Mitral valve prolapse cause mitral regurgitation and increased left atrial and left ventricular diastolic load.
