Aortic sclerosis is a loud murmur that occurs early in systole. It has a diamond shaped appearance when viewed on the Waveform tab.
S1 and S2 are normal. Diastole is silent.
The murmur is characterized by regular vibrations which give the murmur a musical quality ("cooing"). It is caused by turbulent blood flow into the aorta.
Aortic sclerosis can indicate a risk of cardiovascular events and aortic valve obstruction.
