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 :(
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 ...
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?
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.
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.
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.
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.
