And when we have St. Jude's leaflet valve. So important for those checkups. I get them twice a year. And I will be seeing a Cardio Nurse Tuesday to talk about my echo a week ago. We will nail the irregular heartbeat down soon.Sorry I meant <70yo. There is no hard and fast age, <60 works too. Biological valves can have a finite life especially if you are younger. That's why routine echos are prescribed by some cardios for patients with a biological valve.
