You are incorrect - the best description of the acoustic events at the upper right sternal edge is a continuous murmur louder in diastole.
Your choice: Holosystolic + mid diastolic
This is a graphic example of a holosystolic murmur and a mid diastolic murmur. Note that while the systolic murmur extends throughout systole, there is a distinct interval between S2 and the diastolic murmur.
