10 Possible Causes for Cardiomegaly on Chest X-ray, Systolic Thrill at Lower Left Sternal Border

  • Aortic Valve Stenosis

    A 77-year-old, high-risk woman with symptomatic aortic valve stenosis (aortic valve area 0.77 cm(2)) underwent coronary artery catheterization and right heart catheterization. After catheterization, she suddenly developed hemoptysis, and became hypoxic and hypotonic. She was intubated and the bleeding was[…][ncbi.nlm.nih.gov]

  • Ventricular Septal Defect

    3 to 4/6 holosystolic murmur (with or without thrill) at the lower left sternal border; this murmur is usually audible within the first few days of life (see table Heart[msdmanuals.com] Muscular defects can be heard along the lower left sternal border and may vary in intensity as the defect size changes with muscular contraction throughout systole.[circ.ahajournals.org] Diagnosis Chest x-ray and ECG Echocardiography Diagnosis of ventricular septal defect is suggested by clinical examination, supported by chest x-ray and ECG, and established[merckmanuals.com]

  • Patent Ductus Arteriosus

    His chest X-ray showed cardiomegaly and enlargement of the left pulmonary hilum, and an electrocardiogram revealed sinus tachycardia with incomplete right bundle branch block[elsevier.pt] The chest X-ray demonstrated cardiomegaly and increased pulmonary vascular markings.[ncbi.nlm.nih.gov]

  • Tetralogy of Fallot

    Systolic thrill at the lower left sternal border. Aortic ejection click.[patient.info] The chest X-rays on the left posteroanterior and lateral views revealed cardiomegaly and a reduction in the pulmonary flow.[scielo.br] A patient without cyanosis has a long, loud, systolic murmur with a thrill along the right ventricular outflow tract (RVOT).[patient.info]

  • Large Ventricular Septal Defect

    3 to 4/6 holosystolic murmur (with or without thrill) at the lower left sternal border; this murmur is usually audible within the first few days of life (see table Heart[merckmanuals.com] X-Ray chest PA View of a chid with VSD, left to right shunt and hyperdynamic pulmonary hypertension.[pedclerk.bsd.uchicago.edu] X-rays may be normal in small defects; in large VSDs, they may show cardiomegaly, left atrial and left ventricular enlargement, and prominent pulmonary vascular markings.[quizlet.com]

  • Tricuspid Valve Insufficiency

    In severe TR, a right jugular venous thrill may be palpable, as may systolic hepatic pulsation and an RV impulse at the left lower sternal border.[merckmanuals.com]

  • Biventricular Hypertrophy

    3 to 4/6 holosystolic murmur (with or without thrill) at the lower left sternal border; this murmur is usually audible within the first few days of life (see table Heart[msdmanuals.com] A chest X-ray ( Figure 1 ) showed moderate cardiomegaly, and an echocardiogram ( Figure 2 ) confirmed the diagnosis of hypertrophic cardiomyopathy with severe obstruction[revespcardiol.org] , basal crepitations, S3 gallop, clinical acute pulmonary oedema, pulmonary upper lobe blood diversion on chest X-ray (or pulmonary oedema on chest X-ray).[ispub.com]

  • Right Ventricular Hypertrophy

    3 to 4/6 holosystolic murmur (with or without thrill) at the lower left sternal border; this murmur is usually audible within the first few days of life (see table Heart[merckmanuals.com] Diagnosis Chest x-ray and ECG Echocardiography Diagnosis of ventricular septal defect is suggested by clinical examination, supported by chest x-ray and ECG, and established[merckmanuals.com] If the VSD is large, chest x-ray shows cardiomegaly and increased pulmonary vascular markings.[merckmanuals.com]

  • Septic Embolus

    A systolic thrill was palpable at the lower left sternal border. Localized crackles were audible at the base of the right lung.[comprped.com] Chest x-ray revealed moderate cardiomegaly with a prominent pulmonary artery segment and increased pulmonary vascular markings.[comprped.com] On cardiac examination, a grade 4/6 harsh pansystolic murmur at the lower left sternal border and a loud second heart sound were detected.[comprped.com]

  • Multiple Ventricular Septal Defects

    A localized harsh, holosystolic murmur which is best heard at the lower left sternal border, detected after 4-8 weeks of age or later.[medicaljoyworks.com] The chest X-ray showed cardiomegaly with increased bronchovascular markings in both the lung fields.[ijaweb.org] Figure 11 The chest x-ray, viewed in the antero-posterior projection, from a typical patient with ventricular septal defect shows cardiomegaly, increased pulmonary vascular[ojrd.biomedcentral.com]
