This video, created by Nucleus Medical Media, shows Transcatheter Aortic Valve Implantation (TAVI). Stenosis, or narrowing, of the aortic valve due to calcification of the valve leaflets is also depicted. The animation finishes by showing a minimally invasive procedure called a transfemoral aortic valve implantation. This procedure is done to replace a calcified and stenotic aortic valve in patients not able to have open surgery.

Kudos for the one who invented this method. God bless doctors
it wasn't the blessing of a magic man who created and invented these devices and procedures; but science and training- no gods involved.

I appreciate this video since it lets me know what my grandfather will experience tomorrow
looks so simple, yet so brilliant...thanks a lot
Watching these videos makes me want to take better care of myself because the procedures seem painful....
I always end up watching this while eating a Big Mac :(
hehe...it is actually much better than the traditional open heart surgery :)
Whoever made that is awrsome
The genius whoever invented this,OMG his brain is something else WOW!!
TAVI has progressed greatly over the years. In the early days, rejection tissue started to block the capillaries at the top of the aorta that feed blood to the heart muscles. This resulted in a 5 year prognosis and the patient on a permanent cocktail of anticoagulants. This was why the procedure was only used towards the end of a patients life, when he would not have survived conventional surgery.
Today, the stent portion of the synthetic valve extends further up the aorta. This is expanded slightly further to keep the capillaries open. Along with improved synthetics, this has led to a nominal 25 year prognosis following the procedure and the anticoagulants are as little as 80mg of Aspirin per day. This considerably reduces the risk of neurological and stomach aneurism.
Synthetic heart valves predate TAVI by a couple of decades, but they were surgically fitted clear of the heart, further up the aorta and clear of vital capillaries. Contrary to this video, the natural aortic valve was more likely to constrict, rather than not close correctly. Therefore it also had to be surgically removed.
TAVI can also be used to replace the pulmonary valve and fit a clip to repair a torn mitral valve. The later was not very successful and is rarely used these days.
All this was the result of doctors and medical companies working together for more than a decade, rather than the brainchild of one person.
VAD, (ventricle assist devices) are another useful device as a bridge to surgery where a donor organ needs to be found.
PS, I am not a surgeon, but I worked in cardio thoracic research for a number of years.
Hello and thank you for this video. Can a TAVI valve be placed in another Tavi Valve to replace the first Tavi ? Has this already been done ? Thank you for your answers ...
Excellent! What type of tissue does the new valve contain?
+/- 10 years...
Mostly pig or allograft valves are used.
Pig pericardium inside a ring of nitinol (CoreValve) or Cow pericardium insode a crome-cobalt mesh (Edwards Sapien)
You are brilliant. Thank you.
Thank you too!
Will a strong bump from the chest can cause TAVI to loose in place?
This procedure was invented by Prof. Alain Cribier of the University de Rouen in 2002. Its a fantastic procedure!
One of many strides in medicine originating in France
Super simple explanation
Have had this done
So the stent will stay in the heart?? Forever?
that fossilized stent will be you!
Yep!
The same thing is true when you get coronary artery stents for heart attacks. They stay there forever.
I am impressed in awe...
it's good for sport person in future? 22 years old or better surgery
Life time of this stain ? can the stain remove from fixed position ?
A pleasamt day, my father undergo on TAVR operation. More than a year after more follow up check up on our doctor. They diagnosed that the damage vavled keloid is still expanding and needs dor a valve replaxement. Is it possible that the TAVR operation seems to malfunction?
Excellent video
I think drinking too much milk can be also not a good idea, here in ireland people drink lots of milk
Thanks to alain cribier ❤
Do these stents ever cause damage or slip?
They usually don't, however sometimes if there is a mismatch in size the new valve might not close properly and blood will be able to fall back into the heart creating a problem of aortic regurgitation. However, its not too common. Overall survival rates for those with TAVI was 50%+ after 3 years while with medical management it was only 10% after 3 years. This was called the PARTNER trial, it was a huge multicentre trial that involved many patients. 50%+ might sound low but you have to remember most of these patients are very old and frail and have other health issues.
calcium makes good substrate for stent to grab into - it is positioning the valve that you do not want to screw up
in a video the aortic 3 thing are cusps
is there a chance of the baloon popping or being damaged in any case, is this possible?
how long can this replacement valve last?
Can anyone provide me with answers please.
AssadVlogs I guess there is always risk for multiple complications!
Mick Jagger approves this video 😁
How if the aortic regurgitation ? Can use the method or TAVI ?
I believe so
This why we study trigonum femorale :D
How much cost....TAVR...
C’est cette opération que je vais subir ce mois de janvier 20202
THANKS MEDICAL SCIENCE
Vall veliditi ??
Amazing!
Love this!!!!!!!!!!
Kitna cost he
I feel sorry for people with hypercalicmia cause it not only disrupts all the muscles and nervous system but your at a very high chance of this happening to you and that huge bill.
Oeo ur name.
How many maximum life of this valve ?
10^9 cycles
@@dronlaa so about 20-25 years?
Incredible!
Subhan Allah
Really bring religion to this? Ok is long as you aren't the bad guy.

That's why you should workout
Working out makes no difference, everyone will get calcium build up on this heart valve as they get older, it just depends how severely calcified it gets to warrant surgery.
It can be genetic
thnx sir
I wish I didn't have a heart now.

I'm going to have to have this done eventually
always say "alhamdullah " thanks god for the health

This is nikki anderson i been married for eleven years
The human body is disgusting. But lots incredible at the same time!
😍
See how God(Allah) created us.Amazing.Alhamdu lillah.
I'm not too happy about this, I'd prefer for God not to allow calcification on the Aortic Valve.
Jesus created us not allah
not ALLAH!
