77 Possible Causes for Left Atrial Hypertrophy, Thickening of the Mitral Valve Leaflets

  • Mitral Valve Stenosis

    ECG left atrial enlargement may precipitate atrial fibrillation right ventricular hypertrophy concomitant left atrial enlargement without left ventricular hypertrophy is especially[] Mitral stenosis is characterized by thickening and immobility of the mitral valve leaflets.[] This enlarges the left atrium and results in hypertrophy of the atrial wall because the left atrium has to generate increased pressure when it contracts in order to complete[]

  • Mitral Valve Disease

    Features associated with chronic MR are left ventricular and left atrial hypertrophy, and ST segment changes in lateral leads.[] At surgery, nodular thickening of both valves and fusion of the posterior leaflet of the mitral valve were seen.[] […] by weakening and ballooning Etiology Rheumatic heart disease–thickening, rigidity, retraction of mitral valve leaflets; ASHD, HTN, left ventricular enlargement, connective[]

  • Mitral Valve Insufficiency

    Acute Chronic Electrocardiogram Normal P mitrale, Atrial fibrillation, left ventricular hypertrophy Heart size Normal Cardiomegaly, left atrial enlargement Systolic murmur[] Abstract Mitral valve insufficiency in rheumatic heart disease is often due to retracted posterior chordae and posterior leaflet thickening.[] valve prolapse were classified into two groups: those with thickening and redundancy of the mitral valve leaflets ("classic") and those without ("non classic") in an attempt[]

  • Aortic Valve Disorder

    […] ventricle [18] [19] and atrium [18] ECG showing left ventricular hypertrophy and left atrial abnormality [18] Echocardiography is diagnostic in most cases, showing left ventricular[] The inflammed leaflets thicken, fuse at the edges and calcify. The resulting mitral stenosis causes pressure in the left atrium to increase.[] As well, the P waves may show evidence of left atrial enlargement.[]

  • Hypertensive Heart Disease

    On univariate analysis, MACE was associated with older age, atrial fibrillation, concentric LV hypertrophy, larger left atrial volume, and more abnormal GLS.[] Calcific deposition on base posterior mitral valve leaflet Thrombi on ATRIAL surface or ATRIAL wall fibrous thickening at leaflet friction areas (and at mural endocardium[] Although phenotypical characteristics of the hypertrophied left ventricle are clear, left atrial (LA) and pulmonary venous (PV) remodeling has rarely been investigated.[]

  • Aortic Valve Insufficiency

    […] ventricular hypertrophy Left atrial enlargement Chest X-ray Cardiomegaly (cor bovinum) Dilated aortic root Cardiac Catheterization Supravalvular angiography allows assessment[] leaflets and in the mitral subvalvular apparatus, causing thickening, retraction, and stiffening of valves and resulting in incomplete leaflet coaptation and valve regurgitation[] […] ventricular hypertrophy and left atrial enlargement.[]

  • Giant Left Atrium

    An ECG revealed evidence of left ventricular hypertrophy with repolarization abnormalities.[] His echocardiogram showed a rheumatic mitral valve with thickening of the leaflet tips and failure of coaptation together with a severe jet of central mitral regurgitation[] The mitral annulus was calcified. In a pattern consistent with post-rheumatic changes the mitral valve leaflets were thickened and partially calcified.[]

  • Rheumatic Heart Disease

    Echocardiography evaluation showed thickened aortic and mitral valve leaflets with mild to moderate degree of mitral regurgitation.[] The mitral valve can be thickened, calcified, have restricted movement and the mitral valve leaflets fused together. The aortic valve may also be thickened.[] Mitral valvulitis can occur causing thickening of the leaflets. A murmur is created by increased blood flow across the thickened mitral valve.[]

  • Restrictive Cardiomyopathy

    In restrictive cardiomyopathy the P waves may be wide, but have a particular tendency to be increased in amplitude, reflecting left atrial overload or hypertrophy, as in hypertension[] Echocardiography may show endomyocardial thickening, ventricular apical obliteration, and tethering of mitral and tricuspid leaflets. [13] The prognosis is poor for patients[] Six of these individuals (III-1, III-3, IV-5, III-6, III-11, III-15) had left ventricular wall hypertrophy of 13–20 mm, including three individuals with a left atrial size[]

  • Left Atrial Ball Valve Thrombus

    Electrocardiograna showed atrial fibrillation with normal axis deviation and remarkable left ventricular hypertrophy.[] During TEE examination, mid esophageal 4-chamber view showed a severely stenotic mitral valve with thickened and calcified leaflet, severe LA dilatation with spontaneous echo[] The left atrial (LA) volume was assessed by the biplane area-length method from apical four- and two-chamber views, with measurements obtained in end systole from the frame[]
