391 Possible Causes for Left Atrial Enlargement, Pulmonary Hypertension

  • Mitral Valve Stenosis

    […] features include 2, 4-6 : left atrial enlargement convexity or straightening of the left atrial appendage just below the main pulmonary artery (along left heart border) double[radiopaedia.org] hypertension (preoperative mean systolic pulmonary artery pressure was 72 /-12 mmHg, range from 60 to 105 mmHg).[ncbi.nlm.nih.gov] Over time, pulmonary hypertension causes right heart failure, tricuspid incompetence and pulmonary regurgitation.[symptoma.com]

  • Pulmonary Artery Stenosis

    The abnormality of the valve may predispose patients to infective endocarditis; to left atrial enlargement and atrial arrhythmias; or to left ventricular failure. pulmonary[medical-dictionary.thefreedictionary.com] pulmonary hypertension.[ncbi.nlm.nih.gov] This is a case report about a 56-year-old female patient with primary pulmonary hypertension who underwent single, right lung transplantation.[ncbi.nlm.nih.gov]

  • Cor Triatriatum

    An echocardiogram (Panel B) showed normal left ventricular function, an enlarged and globally hypokinetic right ventricle, right atrial enlargement, and a membrane in the[nejm.org] Cor triatriatum sinister is a congenital heart disorder that can lead to progressive dyspnea, pulmonary hypertension, and ultimately right ventricular (RV) failure.[ncbi.nlm.nih.gov] ECG showed sinus tachycardia with left atrial hypertrophy (Fig.-2).[ibimapublishing.com]

  • Mitral Valve Insufficiency

    In acute mitral regurgitation, radiographic signs of left atrial enlargement are often absent 5 .[radiopaedia.org] The splitting interval diminishes as pulmonary hypertension starts.[symptoma.com] They found that, compared with patients with nonsevere pulmonary hypertension (systolic pulmonary artery pressure 41 6 mm Hg), patients with severe pulmonary hypertension[onlinejacc.org]

  • Ventricular Septal Defect

    Furthermore, the increased pulmonary flow leads to left atrial enlargement and increased left ventricular preload and stroke volume by the Frank-Starling mechanism.[cvphysiology.com] hypertension.[ncbi.nlm.nih.gov] Larger VSDs may show cardiomegaly (particularly left atrial enlargement although the right and left ventricle can also be enlarged).[radiopaedia.org]

  • Persistent Truncus Arteriosus

    The electrocardiogram usually shows both right and left ventricular hypertrophy. A left atrial enlargement may be present if pulmonary over-circulation is marked.[symptoma.com] He had unilateral pulmonary hypertension from migration of pulmonary artery band from the main to the right pulmonary artery, severe truncal valve regurgitation from previous[ncbi.nlm.nih.gov] Substantial pulmonary overcirculation may produce evidence of left atrial enlargement.[merckmanuals.com]

  • Heart Failure

    A major clue to the presence of grade II diastolic dysfunction vs. normal diastolic function is the presence of structural heart disease such as left atrial enlargement, left[healio.com] Pulmonary hypertension has not been described as a complication of hypernatremia.[ncbi.nlm.nih.gov] Echocardiographic findings were helpful for the diagnosis of cardiac amyloidosis: enlarged atrial cavities, normal size ventricles, thickened ventricular septum and posterior[ncbi.nlm.nih.gov]

    atrial enlargement.[ncbi.nlm.nih.gov] Doppler evidence of pulmonary hypertension was present in 36%. At least 1 measure of structural heart disease was present in 93% of patients.[ncbi.nlm.nih.gov] […] remodeling (34%) and hypertrophy (43%), and left atrial enlargement (53%).[ncbi.nlm.nih.gov]

  • Angina Pectoris

    Echocardiography showed normal left ventricular function, mild left ventricular hypertrophy, moderate left atrial enlargement with mild mitral insufficiency, and moderate[ncbi.nlm.nih.gov] We present the case of a 48-year-old woman who was diagnosed with pulmonary artery dilatation due to severe, thromboembolic pulmonary hypertension.[ncbi.nlm.nih.gov] Cardiopulmonary status is evaluated for evidence of tachypnea, dyspnea, diaphoresis, pulmonary crackles, bradycardia or tachycardia, altered pulse strength, the appearance[medical-dictionary.thefreedictionary.com]
