What Does a Pda Murmur Sound Like

The murmur may be only a systolic ejection murmur, or it may be a crescendo/decrescendo systolic murmur that extends into diastole. Occasionally, auscultation of the patent ductus arteriosus (PDA) reveals numerous clicks or noises resembling shaking dice or a bag of rocks.

How is the murmur of PDA described?

The murmur of a PDA is described as a medium pitched high-grade continuous murmur heard best at the pulmonic position, with a harsh machinelike quality that often radiates to the left clavicle.

Does PDA cause murmur?

A patent ductus arteriosus causes a continuous murmur since there is a constant pressure gradient in both systole and diastole forcing blood from the aorta into the pulmonary artery.
