What is a specific indicator of a fenestrated aortic valve?

A fenestrated aortic valve is characterized by the presence of small openings or "fenestrations" in the valve leaflets, which can have unique hemodynamic implications. One of the specific indicators associated with this condition is the diastolic flutter of the aortic valve.

This diastolic flutter occurs due to the abnormal motion of the valve leaflets as blood flows through the fenestrations, causing them to vibrate or flutter rather than closing tightly during diastole. This movement can often be visualized with echocardiography and serves as a diagnostic hallmark of fenestrated aortic valves.

The other signs and sounds associated with cardiac conditions, like a holosystolic murmur, late diastolic click, or early systolic ejection sound, do not specifically indicate the presence of a fenestrated aortic valve. Each of these may relate to other cardiac pathologies, but they lack the distinctive motion characteristics observed in fenestrated valves.
