Having my aortic valve replacement surgery next month.i need to relocate to a different country. how long before i can do that. any supervision needed?

3 months: Wait at least 3 months. If you have no complications by that time, you should be good to go. At your (young) age, i presume you'll receive a mechanical valve since a bioprosthetic valve won't last long enough. You'll need warfarin/coumadin and will need close medical supervision of your protimes/inr in your new home. Get hooked up with a cardiologist or other doctor there as soon as possible.

Variable: Which cause? Why? Leak or stenosis? Mechanical with anticoagulation requires blood tests and followups. May wish to have biological valve and avoid anticoagulation, unless also in afib or heart failure. Complex questions and need to discuss fully with your cardiovascular surgeon.
