Hi, my father (who is 65) NEEDS a mitral valve heart replacement (due to past complications with Endocarditis whilst already having a damaged mitral valve). He is getting more sick by the day but is putting off the operation as he is TERRIFIED about having it done. I know this is a big ask, but can anyone provide me with a surgical procedure explanation that i can show him/read to him that won't freak him out? He is considering this op' will kill him... Thank you in advance!!!
