What sound does a VSD make?

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.

What does an atrial septal defect sound like?

A soft midsystolic murmur at the upper left sternal border with wide and fixed splitting of the 2nd heart sound (S2) is common. Diagnosis is by echocardiography.

When do you hear a VSD murmur?

The murmur is commonly discovered at 2-4 weeks of age as the pulmonary vascular resistance drops and the pressure difference between the two ventricles becomes remarkable (Figure).

How common is VSD in babies?

Ventricular septal defects are among the most common congenital heart defects, occurring in 0.1 to 0.4 percent of all live births and making up about 20 to 30 percent of congenital heart lesions. Ventricular septal defects are probably one of the most common reasons for infants to see a cardiologist.

Is a VSD systolic or diastolic?

Mid-diastolic murmurs (rumble) are due to increased flow (relative stenosis) through the mitral (VSD) or the tricuspid valves (ASD). Late diastolic murmurs are due to pathological narrowing of the AV valves. Example: rheumatic mitral stenosis.

What is the most common type of VSD?

Muscular VSD. An opening in the muscular portion of the lower section of the ventricular septum. This is the most common type of VSD. A large number of these muscular VSDs close spontaneously and do not require surgery.

Do all babies with VSD have Down syndrome?

An additional weakness is that although all newborns had a neonatal echocardiogram, the type of VSD was not recorded in many. Since none had trisomy 21, this does not affect our overall conclusion that a prenatally visualized VSD is not associated with a significant risk for Down syndrome.

When do VSD symptoms start?

Signs and symptoms of serious heart defects often appear during the first few days, weeks or months of a child’s life. Ventricular septal defect (VSD) symptoms in a baby may include: Poor eating, failure to thrive. Fast breathing or breathlessness.
