What does ventricular septal defect sound like?

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 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 …

How would you describe a VSD murmur?

The murmur of VSD is typically pan-systolic best heard in the left lower sternal border; it is harsh and loud in small defects but softer and less intense in large ones. Infundibular defects are best heard in the pulmonic area.

Why does VSD cause systolic murmur?

A systolic ejection murmur may be heard in the pulmonary area due to increased flow across the pulmonary valve (relative pulmonary stenosis). A mid-diastolic murmur may be heard at the lower left sternal border due to increased flow across the tricuspid valve.

How would you describe ventricular septal defect?

A ventricular septal defect (pronounced ven·tric·u·lar sep·tal de·fect) (VSD) is a birth defect of the heart in which there is a hole in the wall (septum) that separates the two lower chambers (ventricles) of the heart.

What kind of sound does a ventricular septal defect make?

This condition is known as a ventricular septal defect. The first heart sound is normal. The second heart sound is unsplit. There is a third heart sound followed by a short diamond shaped diastolic murmur. A medium pitched murmur fills all of systole.

Which is the right side of the infundibular septum?

The right side of the infundibular septum is more extensive. Defects in the infundibulum are called infundibular, outlet, supracristal, conal, conoventricular, subpulmonary, or doubly committed subarterial defects.

Can a deficient infundibular septum affect great arteries?

A deficient infundibular septum may be present with corresponding degrees of malalignment. All defects should be assessed for location, size, and multiplicity. The relationship of the defect to the atrioventricular valves, infundibular septum, and great arteries should be noted.

What does it mean to have a septal defect?

Ventricular Septal Defect. In a percentage of individuals a defect in the wall persists allowing blood flow from the left ventricle into the right ventricle. This condition is known as a ventricular septal defect. The first heart sound is normal. The second heart sound is unsplit. There is a third heart sound followed by a short diamond shaped…
