275 Possible Causes for Heart Murmur, Left Atrial Enlargement

  • Mitral Valve Insufficiency

    In acute mitral regurgitation, radiographic signs of left atrial enlargement are often absent 5 .[radiopaedia.org] Your doctor might first suspect you have mitral valve regurgitation upon detecting a heart murmur.[mayoclinic.org] To ensure proper cardiac function, please remember to get regular, annual check-ups if you have been diagnosed with a heart murmur, a mitral valve prolapse or mitral valve[heart-valve-surgery.com]

  • Hypertrophic Cardiomyopathy

    Left ventricular diastolic dysfunction may lead to compensatory left atrial hypertrophy, with signs of left atrial enlargement (“ P mitrale “) on the ECG.[lifeinthefastlane.com] To our knowledge, this is the first case in which heart murmurs associated with a diastolic paradoxical jet flow have been clearly described.[ncbi.nlm.nih.gov] These sounds include an abnormal heartbeat or a heart murmur.[medstarwashington.org]

  • Cardiomyopathy

    Common ECG associations with DCM Left atrial enlargement - may progress to atrial fibrillation.[lifeinthefastlane.com] (Heart murmurs are extra or unusual sounds heard during a heartbeat.) Updated: June 22, 2016[web.archive.org] heart murmur.[ucsfbenioffchildrens.org]

  • Cardiomegaly

    , left Atrial enlargement, right Bilat atrial enlargement Bilateral enlargement of atria Cardiomegaly (enlarged heart) Hypertrophy or dilatation of right ventricle Left atrial[icd9data.com] ‘Manifestations include cardiomegaly, heart murmur (mitral regurgitation, aortic regurgitation), friction rub secondary to pericarditis, and congestive heart failure.’[en.oxforddictionaries.com] Heart murmur: For people who have an enlarged heart, two of the heart's four valves — the mitral and tricuspid valves — may not close properly because they become dilated,[en.wikipedia.org]

  • Mitral Valve Stenosis

    ECG left atrial enlargement may precipitate atrial fibrillation right ventricular hypertrophy concomitant left atrial enlargement without left ventricular hypertrophy is especially[radiopaedia.org] In most cases, you can't prevent heart murmurs.[webmd.com] This can be compounded by atrial fibrillation , a complication of left atrial enlargement, which results in the loss of the 'atrial kick' at the end of diastole and an even[radiopaedia.org]

  • Mitral Valve Prolapse

    A transesophageal echocardiography examination demonstrated left atrial enlargement and severe prolapse of the posterior mitral leaflet associated with severe MR to the dome[ncbi.nlm.nih.gov] The occurrence of total MVP tended to be higher in the group with MVI (47%, 9/19), when compared with the younger CKCS without heart murmurs (13%, 2/15, P 0.06).[ncbi.nlm.nih.gov] Atrial fibrillation. Reduced LV systolic function. Left atrial enlargement. Patients at high risk need follow-up to monitor for progressive mitral regurgitation.[patient.info]

  • Mitral Valve Disease

    Other remarkable features include prolonged P wave in lead II, which is indicative of left atrial hypertrophy.[symptoma.com] In some cases, the prolapsed valve lets a small amount of blood leak backward through the valve, which may cause a heart murmur.[heart.org] Severe left atrial enlargement associated with mitral valve disease has been known to carry a poor prognosis in patients undergoing mitral valve repair or replacement.[ncbi.nlm.nih.gov]

  • Patent Ductus Arteriosus

    Can have cardiomegaly (predominantly left atrial and left ventricular enlargement if not complicated).[radiopaedia.org] Symptoms A heart murmur is usually the first sign of PDA newborns. A small PDA may not cause significant problems, so it is usually not treated.[preemies.about.com] Heart murmurs also have other causes besides PDA, and most murmurs are harmless.[pediatricct.surgery.ucsf.edu]

  • Papillary Muscle Dysfunction

    Chest X Ray Left atrial enlargement may be present Echocardiography and Doppler Ultrasound Two dimensional electrocardiograph may show changes in thickness of papillary muscle[wikidoc.org] A history of cardiogenic shock, acute congestive heart failure with cyanosis and atrioventricular murmur, or persistent fetal circulation in a newborn without congenital heart[ncbi.nlm.nih.gov] Advanced age, previous MI, and heart failure were all associated with systolic murmur (p less than 0.01).[ncbi.nlm.nih.gov]

  • Aortic Valve Stenosis

    […] only in decompensated aortic stenosis, and possibly left atrial enlargement as well Narrowing of retrocardiac space (lateral view) Calcification of aortic valve : signs of[amboss.com] The diagnosis may have been made when the health care provider heard a heart murmur and performed tests.[nlm.nih.gov] (B) The horizontal four-chamber view shows the resultant severe left ventricular hypertrophy and left atrial enlargement.[aafp.org]
