17 Possible Causes for Right Atrial Hypertrophy, Systolic Thrill at Lower Left Sternal Border

  • 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] In those with pulmonary hypertension, right axis deviation, right ventricular hypertrophy (RVH) and right atrial hypertrophy (RAH) may be seen.[patient.info] 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]

  • Tetralogy of Fallot

    Systolic thrill at the lower left sternal border. Aortic ejection click.[patient.info] A right aortic arch is present in 25%. ECG shows right ventricular hypertrophy and may also show right atrial hypertrophy.[msdmanuals.com] On admission, the electrocardiogram showed sinus tachycardia and right atrial and ventricular hypertrophy.[scielo.br]

  • 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] In those with pulmonary hypertension, right axis deviation, right ventricular hypertrophy (RVH) and right atrial hypertrophy (RAH) may be seen.[patient.info] Small VSDs typically produce murmurs ranging from a grade 1 to 2/6 high-pitched, short systolic murmur (due to tiny defects that actually close during late systole) to a grade[merckmanuals.com]

  • Patent Ductus Arteriosus

    In the patient with a large ductus arteriosus and elevated pulmonary artery pressure, signs of right atrial enlargement and biventricular hypertrophy are frequently present[doi.org] Electrocardiogram The ECG may reveal sinus tachycardia, atrial fibrillation, left ventricular hypertrophy, as well as a left atrial enlargement in individuals with medium[lecturio.com] An enlarged right atrium, hypertrophy of both ventricles and increased pressure of the pulmonary artery is observed in patients with large holes.[lecturio.com]

  • Left to Right Cardiac Shunt

    Auscultatory findings Harsh h olosystolic murmur over the left lower sternal border ; typically louder in small defects Mid- diastolic murmur over cardiac apex Systolic thrill[amboss.com] […] elevated pulmonary vascular resistance, and right ventricular hypertrophy; supraventricular tachycardia, atrial flutter, or atrial fibrillation may also occur.[merckmanuals.com] This chronic development of right‐to‐left shunt (RLIAS) is accompanied by electrocardiographic changes of atrial enlargement and right ventricular hypertrophy.[academic.oup.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] Right atrial overload and right ventricular hypertrophy Right atrial overload and right ventricular hypertrophy Right atrial overload (P pulmonale) and right ventricular hypertrophy[cardiophile.org] Echocardiography revealed dilated right heart chambers. The ECG shows right ventricular hypertrophy and right atrial abnormality. Pediatric cardiologist Dr.[metealpaslan.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] Right atrial hypertrophy (RAH) In RAH, the right atrial component of the P wave is increased in both voltage and duration.[frca.co.uk] Related Topics Right ventricular hypertrophy Left ventricular hypertrophy Right atrial enlargement Left atrial enlargement Katz-Wachtel phenomenon Louis Nelson Katz (1897[lifeinthefastlane.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] Investigations ECG may show evidence of right atrial hypertrophy with tall peaked P waves; arrhythmias (eg, atrial fibrillation, atrial flutter) occur frequently.[patient.info] ECG is usually normal but, in advanced cases, may show tall peaked P waves caused by right atrial enlargement, a tall R or QR wave in V 1 characteristic of RV hypertrophy,[merckmanuals.com]

  • Anomalies of Great Veins, Congenital

    On examination, there is a systolic murmur at the lower left sternal border (LLSB), and a systolic thrill may be present if there is a large shunt.[ahcmedia.com] The electrocardiogram shows right ventricular hypertrophy and right atrial hypertrophy.[hawaii.edu] […] axis deviation due to RVH Tall P waves due to right atrial hypertrophy Right bundle branch block Prolonged PR interval WPW syndrome Treatment Cyanosis usually worsens as[amboss.com]
