11 Possible Causes for Biventricular Hypertrophy, Mesocardia, Normal Electrocardiogram

  • Corrected Transposition of the Great Vessels

    hypertrophy.[] Laboratory investigations including haematocrit and electrolytes were normal.[] 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.[]

  • Transposition of the Great Vessels

    In those with a large VSD biventricular hypertrophy may be seen.[] 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.[]

  • Congenitally Uncorrected Transposition of the Great Arteries

    The main electrocardiographic features are a rightward deviation of the QRS complex axis associated with right ventricular hypertrophy; biventricular hypertrophy is evident[] Asymptomatic women with unremarkable resting electrocardiograms, a normal exercise test, good left ventricular function and a pre-pregnancy aortic valve peak pressure drop[] […] 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[]

  • Ebstein Malformation

    AF indicates atrial fibrillation; ALCAPA, anomalous left coronary artery from the pulmonary artery; AVB, AV block; AVN, AV node; BVH, biventricular hypertrophy; CHD, congenital[] 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[]

  • Situs Inversus

    hypertrophy Patent foramen ovale Abnormal hair quantity Unconjugated hyperbilirubinemia Cardiomegaly Dyskinesia Pulmonic stenosis Recurrent respiratory infections Arrhythmia[] […] with normal lead placement showed marked right axis deviation with negative p wave in lead aVL and I.[] Mesocardia, a midline heart is sometimes regarded as a fourth malposition.[]

  • Anomalies of Great Veins, Congenital

    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.[] 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[]

  • Discrete Fibromuscular Subaortic Stenosis

    This may show biventricular hypertrophy, or it may be normal. Chest Radiography. This may demonstrate generalized cardiomegaly and usually heart failure.[] The electrocardiogram depicted a heart rate of 90 beats/min, normal sinus rhythm, and right ventricular enlargement.[] At least 20% of patients have mesocardia or dextrocardia [ 13 ].[]

  • Subpulmonary Stenosis

    Assess the feasibility of biventricular repair or need for pulmonary artery banding.[] […] with mild pulmonary valve stenosis will have a normal electrocardiogram.[] The electrocardiogram is typically normal in the presence of mild pulmonary stenosis.[]

  • Moynahan Syndrome

    A cardiological review indicated that ECG abnormalities occur in about 75% of the patients, including left or biventricular hypertrophy in 46% of them, often in association[] An electrocardiogram is used in some centers to diagnose conduction abnormalities, such as right bundle branch block.[] Congenital atrichia associated with situs inversus and mesocardia. Int J Trichol 2012;4:181-3 5. Sinclair R, de Berker D.[]

  • Multiple Ventricular Septal Defects

    With large VSDs the ECG shows biventricular hypertrophy (BVH) with or without LAH.[] Haematological and biochemical investigations were within normal limits.[] Dextrocardia, mesocardia, and levocardia: the segmental approach in congenital heart disease. In: Keith JD, Rowe RD, Vlad P, eds.[]
