Mitral Valve Prolapse, Familial, Autosomal Dominant
Mitral Valve Prolapse, Familial, Autosomal Dominant Causes
Mitral valve prolapse is caused by the displacement of an abnoramally thick mitral valve leaflet into the left atrium during systole. The disease frequently occur in persons with Marfan syndrome.
Mitral Valve Prolapse, Familial, Autosomal Dominant Definition
Mitral valve prolapse is a heart disease in which during systole, the mitral valve leaflet is displaced into the left atrium. An individual with this disease has an abnormally thick mitral valve leaflet.
Mitral Valve Prolapse, Familial, Autosomal Dominant Diagnosis
Physicians examine patients through echocardiography, which visualizes the mitral leaflets relative to the mitral annulus. This procedure helps in the measurement of the leaflet thickness and their displacement relative to the annulus. Mitral valve leaflets with >5 mm thickness and >2 mm leaflet displacement indicates a classic mitral valve prolapse.
Mitral Valve Prolapse, Familial, Autosomal Dominant Symptoms and Signs
Symptoms may cause patients to experience chest pains, heart palpitations, shortness of breath, atrial fibrillation, or syncope. The symptoms are usually not directly caused the mitral valve's prolapse but by the mitral regurgitation that often due to prolapse. The disease has been linked with anxiety and panic attack disorders. Patients usually have a low body mass index and leaner than normal individuals.
