I don't know much about the Melody Valve myself because it was not really an option for me. (I can't have femoral vein caths because of an interrupted veinous pathway.) I only mention it here as it was being encouraged by the Dr.s at Cleveland Clinic as the reason they were going away from mechanical valves and back to bio valves. This may be in very specific instances and dependent on which valve. This was both the dr. Krasuski, the cardiologist and Dr. Pettersson, the surgeon.
Two issues that bothered me about the Melody valve, and please keep in mind this was very preliminary and not thorough researched information. But, I didn't like that it wasn't fully approved yet, and was only being CURRENTLY allowed as humanitarian usage in life threatend circumstances. More importantly, according to the Melody Valve's, producers own website, there is a 35% failure rate of the stint carrier in the first year. I found that statistic very alarming. I asked Dr. P about that and he kind of blew me off that it wasn't important! I disagreed but since I had already decided not to do the bio valve because of the IFVP (Fem Vein issue ) I didn't persue it.
It is important to remember, though, that the valve is brand new and still being researched. The discussions regarding its use are for a FUTURE use WHEN A BIO VALVE NOW BEING PUT IN FAILS, not necessarily being discussed for PRESENT use.
I mentioned it to let folks know to ask their Drs if it might be an option for FUTURE USE for them and to let them know what to research. It may be a deciding factor in the decisions TODAY about getting a bio valve vs a mechanical valve (to refresh, because Melody can't be used to replace a failed mechanical valve). I know FOR ME (having now had 4 OHSs), if I did not have the IFVP issue, I would've been willing to bank on improvements in the Melody Valve between now and WHEN I might need it in the future to avoid a 5th OHS. And knowing about it as a future possible option at the time of deciding bio/mech was appreciated.
These can be hard decisions because we just don't have reliable crystal balls, but having as much information as we can have about issues and options is important in helping us reach these difficult decisions and the point of these forums.
Best of luck to all out there facing valve replacement!
