Question

At a recent appointment, Mr. Heinz's cardiac surgeon warned him that he might need to implant an artificial valve in Mr. Heinz's heart because blood is flowing backward into his right ventricle. Which heart valve will Mr. Heinz MOST likely have replaced by the surgeon?

GPT-5 mini · Answer
