In cases of aortic insufficiency, which of the following symptoms may be observed?

In cases of aortic insufficiency, the presence of a diastolic heart murmur is a hallmark finding. This murmur occurs due to the backflow of blood from the aorta into the left ventricle during diastole when the aortic valve does not close properly. This regurgitation leads to increased volume within the left ventricle, eventually contributing to left ventricular dilation and potential heart failure if the condition progresses.

The characteristic sound of the diastolic murmur can often be heard best along the left sternal border and is typically described as a "blowing" sound. The recognition of this murmur is essential for diagnosing aortic insufficiency and assessing its severity. Other symptoms and findings associated with the condition might include various forms of heart dysfunction as well as signs of volume overload, but the diastolic murmur remains a key indicator directly related to the pathological process of aortic insufficiency.
