Which of the following mechanical prosthetic valves were invented as a replacement for diseased heart valves?
Show Hint
- Globe valve
- Ball and cage valve
- Bi-leaflet valve
- Swing check valve
The Correct Option is B, C
Solution and Explanation
The ball-and-cage valve was one of the earliest mechanical prosthetic heart valves developed for patients with damaged heart valves.
The bi-leaflet valve (such as the St. Jude valve) is a widely used modern mechanical prosthetic valve design.
Step 2: Eliminating non-medical valves.
Globe valves and swing check valves are industrial valves used for fluid control in pipelines and machinery, not in biomedical applications.
Step 3: Conclusion.
Therefore, the correct prosthetic heart valve types are (B) Ball and cage valve and (C) Bi-leaflet valve.
