Describe Systolic Sounds in heart dieases?

Early Systolic Sounds: Aortic or pulmonary ejection sounds are the most common early systolic sounds. These are high frequency sounds.

Generation of Sound: 'As the sound is generated due to abrupt upheld doming of the valve, its presence suggests that the valve is mobile.

Aortic Ejection Sound: Originates in aortic valve as in congenital aortic stenosis or bicuspid aortic valve. These do not vary with respiration.

Pulmonary ejection Sound: Originates in pulmonary valve as in congenital pulmonary valve stenosis. This is the only right-sided sound that decreases on inspiration. This is because during respiration due to increased blood flow to RV, RVEDP raises to level more than pulmonary aitery diastolic pressure. Therefore the pulmonary valve is raised to domed position at the end of the diastole and hence there is no sound or only soft sound when RV contracts. Early systolic sounds accompany mechanical proslheses in the aortic location, but do not occur with bioprosthetic valves.
