The chordae tendineae keep the tricuspid and bicuspid valves from compressing past the point of closure when the ventricles contract. If the chordae tendineae were not functioning properly, the pressure from ventricular contraction would force the valve to open into the atrium and cause backward flow of blood. In summary, blood would flow the wrong direction, decreasing the heart's effectiveness.
What else can I help you with?
What happens if the chordae tendineae is nonfunctional or defective?
the valve would fail to close or would invert when the heart contracts, this may cause heart failure.
What might be the significance or nonfunctional or defective chordae tendineae?

In summary, blood would flow the wrong direction, decreasing the heart's effectiveness.
What might be the significance of a nonfunctional or defective chordae tendinae?
Nonfunctional or defective chordae tendineae can lead to severe cardiac issues, primarily affecting the heart valves, especially the mitral and tricuspid valves. These structures help prevent backflow of blood by anchoring the heart valves to the ventricular walls. If they are damaged, it can result in valve prolapse, regurgitation, or heart failure due to improper blood flow and increased cardiac workload. Consequently, this condition may necessitate surgical intervention to repair or replace faulty valves.
