"broadly" in that they are all bi-leaflet valves - otherwise they are significantly different - the pivot area, the opening angle, overall height, leaflet stability, (claimed) carbon composition, & available sizes.
By "wider" you mean larger diameter. In general, the size of the valve does not affect the cardiac output - the difference is that in a smaller size valve the fluid velocity through the valve will be greater. Too small and it becomes a problem as the resistance to flow becomes a problem and...
I can't imagine how you got that impression - especially after being on VR for years. I have personally seen tissue valves last 6 months - or 20 years. So roll your dice.
@jamie14512, Depending on your build, a 25mm is an "averaged" sized aortic valve. The OnX "carbon" size only goes to 25mm (23.4mm inside dia) then they hang a bigger cuff on it for their size 27/29. SJM has specific sized carbon for each size through 31mm.
Now now Pel, where would those celebrities spend their $ if it wasn't for scientology (yes I used a small "s") ?
Sorry, off the subject of the post, :)
Well, it is a huge deal - that means that nearly 30% of the stroke volume is going "the wrong way". Something that needs to be addressed - nothing a mechanical valve won't fix - you are too young for a tissue valve.
You don't want the leaflets touching anything, the only way I have ever seen a pericardial leaflet develop a hole is when it touched "something" otherwise long term they will calcify, prolapse or tear.
Yep, sutureless is just what is says but according to their video sutures are required (like...
