… necessarily indicate valve malfunction. The closing sound is generally louder than the opening sound with a disk valve; Both the opening and closing sounds are loud with the ball-and-cage type of valve; The closing… An ejection sound is a high-frequency "clicky," early systolic sound. When aortic or pulmonary ejection sounds occur in the presence of normal semilunar valves,…

… begins at the end of isovolumic systole when the ventricular pressures exceed the semilunar valve opening pressure.… An ejection sound at the onset of the murmur suggests congenital aortic stenosis or a bicuspid valve. The ejection sound is usually absent in severe AS.…

Echocardiographic and hemodynamic relationships of ejection sounds.

Mills PG, Brodie B, McLaurin L, Schall S, Craige E.
Circulation. 1977 Sep;56(3)430-6.
The physiologic correlates of ejection sounds have been studied by simultaneous phonocardiograms, echocardiograms and high fidelity pressure tracings. Ejection sounds associated with semilunar valve stenosis or hypertension of the systemic or pulmonary circulation occur at the moment of complete ope

First heart sound and ejection sounds. Echocardiographic and phonocardiographic correlation with valvular events.

Waider W, Craige E.
The American journal of cardiology. 1975 Mar;35(3)346-56.
To provide additional information on the relation of valvular events to the principal components of the first heart sound (s1), combined echocardiograms and phonocardiograms were recorded in 49 subjects, chosen because of audible splitting of S1 or a combination of S1 and an ejection sound. The subj
