Implication

Challenges collision theory of incisura and S2; leaves open human confirmation of rebound mechanism.

Closed chest anesthetized dogs

Intervention

Special electrical contacting device

Outcome

Timing relationship between aortic valve closure and the aortic incisurasurrogate

The aortic pressure incisura and second heart sound result from the rebound of the aortic blood column and walls after valve closure, not from leaflet collision.
