heart, section, the middle, heart, chronic mitral valve regurgitation, mitral valve insufficiency, chronic mitral regurgitation, progressive, long-term disorder, the mitral valve, separates the left upper chamber, the heart, atrium, left lower chamber, ventricle, does not close properly, blood to leak, backflow, regurgitation, left atrium, left ventricle, contraction, the heart, systole, mitral regurgitation, most common type of heart valve insufficiency, disorder that weakens, damages this valve, prevent it from closing properly, causing this type of leakage, mitral regurgitation becomes chronic, the condition persists rather than occurring, a short time period, mitral valve fails to close properly, blood flows back, left atrium, left ventricle, blood flow, cardiac output, decreased, heart pumps harder to try to compensate, chronic mitral regurgitation affects approximately 6% of women, 3% of men, after 55 years of age, degree of mitral regurgitation is found in 20% of men, women who undergo echocardiograms, congenital, present from birth, mitral regurgitation is rare, not part of a more complex heart defect, syndrome, mitral valve prolapse, involves weakening, ballooning out, the valve, affects, 5%, the population, relatively common cause of chronic mitral regurgitation, one-third of all cases of chronic mitral regurgitation, rheumatic heart disease, a complication of untreated strep throat that is becoming less common, rheumatic heart disease, lead to thickening, rigidity, retraction, the mitral valve leaflets, chronic mitral regurgitation, disorders atherosclerosis, hypertension, high blood pressure, left ventricular enlargement, connective tissue disorders marfan's syndrome, congenital defects, endocarditis, infection, the heart valve, cardiac tumors, untreated syphilis, rare, acute mitral regurgitation, become chronic, risk factors include an individual, family history of any, the disorders mentioned, use of fenfluramine, dexfenfluramine, appetite suppressants now banned, four months, longer, fatigue, exhaustion, light-headedness, result from low cardiac output, palpitations, related to atrial fibrillation, cough, shortness of breath, exertion, exertional dyspnea, lying, orthopnea, additional symptoms that associated, urination, excessive at night, no symptoms, symptoms occur, develop gradually, palpation, thrill, vibration, over the heart, a stethoscope examination, the heart reveals a distinctive murmur, rales, a crackly sound, abnormal breath sounds heard on lung examination, ankle swelling, enlarged liver, distended neck veins, signs consistent, right-sided heart failure present, an enlarged left atrium, a thickened, deformed mitral valve, regurgitation of blood seen on, echocardiogram, an ultrasound examination, the heart, transesophageal echocardiogram, tee, cardiac color-doppler study, magnetic resonance imaging, mri, cardiac catheterization, a chest x-ray, an enlarged left atrium, an ecg often suggests left atrial enlargement, enlargement, the left ventricle is also a frequent finding, tests, radionuclide scans, a ct scan, the chest, hospitalization required, diagnosis, treatment of severe symptoms, surgical repair, replacement, the valve is recommended, heart function is poor, severe, condition deteriorates, once the diagnosis of mitral regurgitation is made, periodic follow-up by a specialist is needed, the appropriateness of surgery, antibiotics, prescribed, bacterial infection is present, prior to dental work, procedures in cases of mitral valve prolapse, anti-arrhythmic drugs, medications that regulate the heart rhythm, needed to control irregular rhythms, vasodilators, drugs that dilate blood vessels, to reduce the workload, the heart, digitalis, strengthen the heartbeat, diuretics, water pills, to remove excess fluid, in the lungs, anticoagulant, antiplatelet medications, blood thinners, prevent clot formation, atrial fibrillation is present, atrial fibrillation increases the chances of clot formation, a low-sodium diet helpful, most individuals have no symptoms, a person develops symptoms, activity restricted, depends on the underlying conditions, the condition is benign, no therapy, restriction, controlled, in severe cases, valve repair, valve replacement necessary, endocarditis, infection, the heart valve, heart failure, pulmonary emboli, blood clots, in the lungs, stroke, clots to other areas, arrhythmias, abnormal heart rhythms, atrial fibrillation, lethal arrhythmias, symptoms suggest mitral regurgitation, have mitral regurgitation, symptoms worsen, not improve, signs of infection occur, fever, chills, muscle aches, headache, malaise, general ill feeling, treat strep infections promptly, prevent rheumatic fever, treat other causative disorders, note any history of heart valve disease, congenital heart disease, dentist, dental work, cleaning, invasive procedure, introduce bacteria, bloodstream, bacteria, infect a damaged mitral valve, causing endocarditis, preventive treatment, antibiotics given, dental, invasive procedures, decrease the risk of endocarditis.
