Me, a former news editor: Where was the procedure done? How big was the team? Who, from that team, is mandated to speak to us? What can you tell us about the patient (obviously without identifying them)?

Just imagining the scene in 1967 if Christiaan Barnard had sent a telegram to the papers: "Transplant done (stop). Patient recovering (stop). No need to ask questions comma trust me bro (stop)."
