Aortic regurgitation
Failure of the aortic valve to close completely during ventricular diastole results in aortic regurgitation (blood leaking through the aortic valve). This back flow produces a characteristic murmur. The big red mass seen in the middle is due to the injected material leaking through the aortic valve.
