19 Possible Causes for Left Atrial Hypertrophy, Mesocardia, Normal Electrocardiogram

  • Corrected Transposition of the Great Vessels

    The chest X-ray showed mesocardia. He began to experience signs and symptoms of heart failure in 1992, with a systolic murmur audible over the left sternal border.[] Laboratory investigations including haematocrit and electrolytes were normal.[] […] descending branch and gives rise to a circumflex branch left coronary artery resembles a right coronary artery situs inversus Plain radiograph Chest radiographs may present with mesocardia[]

  • Scimitar Syndrome

    The electrocardiogram showed left axis deviation and chest X-ray revealed cardiomegaly with pulmonary plethora.[] Figure 1 Preoperative Chest X-ray showed a dextroposition and mesocardia with scimitar vein.[] […] conditions Heart failure - Cardiovascular disease - Cardiomegaly - Ventricular hypertrophy ( Left, Right ) Cerebrovascular diseases Stroke - Transient ischemic attack - Intracranial[]

  • Levocardia

    Plain X-ray films of the chest and abdomen showed a normally located heart and a right-sided stomach ( Fig. 1 ). The electrocardiogram was normal with sinus rhythm.[] Other forms of cardiac malposition, including dextrocardia, mesocardia and criss-cross heart, with chest radiograph and CMR correlation, are also discussed.[] atrial hypertrophy.[]

  • Ebstein Malformation

    The electrocardiogram showed normal sinus rhythm, dilation of the right atrium and right bundle-branch block. The chest X-ray film showed a CTR 0.95 (Figure 1).[] The present case report illustrates fetal echocardiographic clues to the diagnosis that include mesocardia and apically displaced attachment of the left-sided atrioventricular[] ; LAHB, left anterior hemiblock; LAI, left atrial isomerism; LV, left ventricle; LVH, left ventricular hypertrophy; NSR, normal sinus rhythm; PHT, pulmonary hypertension;[]

  • Congenital Mitral Stenosis

    Doctors will use chest X-rays, electrocardiograms (ECG) and echocardiograms (Echo) to diagnose congenital mitral valve stenosis.[] […] lipogranuloma Mesenteric panniculitis Mesial temporal lobe epilepsy with hippocampal sclerosis Mesoaxial polydactyly Mesoaxial synostotic syndactyly with phalangeal reduction Mesocardia[] Opening of mitral valve is narrow, which elevates left atrial pressure and leads to left atrial hypertrophy and right ventricular hypertrophy Cardiac catheterization Normal[]

  • Familial Mitral Valve Prolapse

    Electrocardiography The electrocardiogram is often normal in patients with MVP.[] […] lipogranuloma Mesenteric panniculitis Mesial temporal lobe epilepsy with hippocampal sclerosis Mesoaxial polydactyly Mesoaxial synostotic syndactyly with phalangeal reduction Mesocardia[] […] axis deviation ) · QT ( Short QT syndrome ) · T ( T wave alternans ) · ST ( Osborn wave, ST elevation, ST depression ) Cardiomegaly Ventricular hypertrophy ( Left, Right[]

  • Transposition of the Great Vessels

    Electrocardiogram (ECG) shows a right axis deviation and right ventricular hypertrophy. Unfortunately, both sets of ECG findings can be viewed as normal in the newborn.[] Diagnostic Evaluation Chest Radiograph With mesocardia or levocardia, the diagnosis may be suspected from the chest radiograph.[] The RV is hypertrophied, and mixing at the foramen ovale occurs but may be inadequate. Atrial pressures are mean pressures.[]

  • Congenital Pulmonary Veins Atresia or Stenosis

    […] with mild pulmonary valve stenosis will have a normal electrocardiogram.[] Mesocardia Abnormal position of the heart where it occupies a more central position within the chest.[] ECG characteristically shows left axis deviation (between 0 and 90 ) and left ventricular hypertrophy.[]

  • Anomalies of Great Veins, Congenital

    An electrocardiogram may show right ventricular hypertrophy, but this is non-specific since RVH is present in normal newborns.[] […] heart block Complete or incomplete atrioventricular [AV] block 746.87 Malposition of heart and cardiac apex Abdominal heart Dextrocardia Ectopia cordis Levocardia (isolated) Mesocardia[] It may be normal in a small lesion or show LVH and left atrial enlargement (LAE) or biventricular hypertrophy (BVH) and LAE with very large lesions.[]

  • Congenital Partial Pulmonary Venous Return Anomaly

    Chest radiograph and electrocardiogram were normal.[] Dextrocardia or mesocardia was noted in 70%, atrial septal defect in 70%, and increased right ventricular dimension in 70% of the patients.[] Echo cardiograph did not demonstrate any other cardiac anomaly like atrial septal defect (ASD), left ventricular hypertrophy, pulmonary arterial hypertension.[]
