You are incorrect - our patient's acoustic events at the upper right sternal edge are best described as an ejection sound, a systolic ejection murmur, a single accentuated S2 and an early diastolic murmur.
Your choice: ES loudest in expiration + systolic ejection murmur + single S2
This is a graphic example of an ejection sound that varies with respiration, being loudest in expiration, together with a systolic ejection murmur and a single S2. Note both long duration of the systolic murmur and absence of diastolic murmur.
