WebSep 25, 2024 · Intraventricular pressure falls precipitously, causing the aortic valve to snap shut. This causes a brief interruption in the fall of pressure, called the incisura or dicrotic notch. The incisura or dicrotic notch occurs when the aortic valve closes. Pressure then falls to the diastolic pressure.
