    3 decades ticking away!

    Leave the valve alone - it will last far past 100 years of service.

    Advancement and the future of Mechanical Valves/ Blood Thinners, ETC

    No advantage over existing bi-leaflet valves.

    Advancement and the future of Mechanical Valves/ Blood Thinners, ETC

    You'll have to trust me on that one, I can assure you with 100% certainty that this has been around that long.

    Advancement and the future of Mechanical Valves/ Blood Thinners, ETC

    I could elaborate but I can't. Lets just say for legal reasons. And no, the industry is not trying to hide something - if someone can make a buck off of these things they would - and get stuff like this to market ASAP.

    Advancement and the future of Mechanical Valves/ Blood Thinners, ETC

    and.. from the On-X website: It is well documented that the On-X valve does not produce the turbulence and blood damage commonly produced by other mechanical heart valve prosthesis and therefore significantly reduces the potential for life-threatening blood clots. Well, I don't believe it...

    Advancement and the future of Mechanical Valves/ Blood Thinners, ETC

    This valve, or similar, has been out and about for over 20 years - there's a reason its not on the market - yet.

    Advancement and the future of Mechanical Valves/ Blood Thinners, ETC

    The Foldax valve would be considered a "hybrid" valve combining the durability of a mechanical valve with the (relatively) soft closing action of a tissue valve - time will tell. Nothing is happening on the mechanical side. Years (decades) ago, SJM once had a marketing line - Not New, Not...

    Mitral valve first replaced 34yrs ago, looking for help

    St. Jude Medical (now Abbott) sells a couple dozen or so "baby valves" per year and has been at that rate for a number of decades, some go on to find a replacement heart, for others a mechanical valve will remain with them for their entire life. Typically in their early teens they will get an...

    Regurgitation vs Stenosis

    Stenosis means stiff leaflets - stiff leaflets can cause regurgitation because they don't seal properly, however stenosis is typically associated with a higher pressure drop - there is a restriction. Regurgitation (flowing the "wrong way") can also be caused by a leaflet prolapse, a hole, or...

    Back to Back TAVRs

    Tissue valves can last 6 months to 20 years - I've seen both.

    Decision time.

    Maintain a reasonable blood pressure and go with the mechanical - you're to young for a tissue valve.

    Back to Back TAVRs

    There is no correlation. Anything tissue will have a large standard deviation when it comes down to how long it will last.

    Lifting weights

    Moderation is the key - to almost everything. I know a "number" of weight lifters, now in their 50's, that regret their time trying to out-do themselves.

    St Jude's valve 18 years and going strong

    Ambience, good to have you on-board here. Lots of knowledge here in all aspects of heart-valve-ology (not a word - I know :)) with many years of experience. Thanks for the introduction and welcome,

    FDA Clears Edwards Konect Resilia Aortic Valved Conduit For Complex Aortic Valve Surgeries

    It really doesn't change anything with the debate of tissue vs mechanical. Its a "dry" valve - shipped without fluid - the valve comes with a conduit already connected to the valve if the aorta needed replacement. This assembly has been common with mechanical valves for decades but I believe...

    Engineers find thinner tissues in replacement heart valves create problematic flutter

    vitdoc - lets for now, just say I am "in the business". As I am still working I can only say so much. After I retire ("soon") I will be at liberty to discuss these things a bit more freely (although I am still bound my employment agreement).
