Medical and Biotech [MESH] Definitions
Mitral Valve Insufficiency
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
Mitral Valve Prolapse
Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.
Mitral Valve Annuloplasty
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
Mitral Valve Stenosis
Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
Discrete Subaortic Stenosis
A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
We present a 15-week pregnant woman who developed mechanical mitral valve thrombosis on a fixed dose of enoxaparin therapy 60 mg twice daily. No reductions were observed in the thrombus size or mean m...
Non-infective mitral valve diverticulum is extremely rare. We present a case of intraoperatively diagnosed mitral valve diverticulum of a 69-year-old man presenting with mitral regurgitation who was s...
Giant left atrium is a condition characterized by huge enlargement of the left atrium with a diameter exceeding 65mm. It is most commonly associated with long standing rheumatic mitral valve disease....
ABSTRACT: We describe a patient with acute cardiogenic shock due to cardiac involvement in idiopathic hypereosinophilic syndrome (Loffler endocarditis). At the echocardiography, there was a huge mass...
We report a case of acute early bioprosthetic failure after mitral valve replacement with completely preserved annuloventricular continuity. A 77-year-old man with left ventricular dysfunction underwe...
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the v...
Prospective, multi-center, Phase I study of the Evalve Cardiovascular Valve Repair System (CVRS) in the treatment of mitral valve regurgitation. Patients will undergo 30-day, 6 month, 12...
Mitral valve regurgitation (leakage of the mitral valve of the heart) is frequent and currently there is no specific medical therapy. Mitral regurgitation is a slowly progressive disease...
The aim of the study is to evaluate hemodynamic and echocardiographic parameters in patients with secondary mitral insufficiency and CHF. 1. Identification of hemodynamic parameters as...
The primary aim of this study is to assess the changes on the shape and function of the left ventricle in patients with severe mitral valve regurgitation due to congestive heart failure an...
