9 Possible Causes for Systolic Thrill at Lower Left Sternal Border

  • Patent Ductus Arteriosus

    What is it? Patent ductus arteriosus (pronounced pay-tent duck-tus are-teer-e-o-sus) happens when a blood vessel fails to close after a baby is born. The ductus arteriosus is the temporary blood vessel that allows blood to bypass a baby's lungs before it is born. It is a blood vessel that joins the pulmonary[…][web.archive.org]

  • 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] 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[msdmanuals.com]

  • Apical Myocardial Infarction

    This murmur is loudest along the lower left sternal border and is associated with a palpable parasternal systolic thrill. RV and LV S3 gallops are common.[emedicine.medscape.com]

  • Tetralogy of Fallot

    Systolic thrill at the lower left sternal border. Aortic ejection click.[patient.info] A patient without cyanosis has a long, loud, systolic murmur with a thrill along the right ventricular outflow tract (RVOT).[patient.info] […] older child with long-standing cyanosis (without surgery) may present with the following signs: Cardiac Right ventricular predominance on palpation or possibly a bulging left[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] 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]

  • 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] 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[msdmanuals.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] 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]

  • 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]
