Valvular insufficiency leads to which effect?

Explanation:
Valvular insufficiency means the valve leaflets do not close fully, so blood leaks backward into the chamber from which it came when the valve should be shut. This backflow is regurgitation caused by improper closure of the valve cusps. It’s different from a valve opening narrowing, which is stenosis. The idea that there would be no functional consequence isn’t accurate, because this backward flow changes chamber pressures and volumes, often producing a murmur and potential heart failure over time.
