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.
