What is TVAR? If you ask any lay man, he may get scared or take these diseases in a casual manner. In a normal way, if someone has symptoms of:
- Heart rhythms abnormal
- Kidney diseases
- Heart attack or other symptoms of TVAR.
Tran catheter aortic valve replacement (TAVR): When a narrowed aortic valve fails to open properly (aortic valve stenosis), it calls for a replacement. Tran catheter aortic valve replacement (TAVR) is a minimally invasive procedure employed for its replacement.
In this procedure, doctors insert a catheter in the chest and accordingly guide it to the heart. By the time any person reaches the age of 75, his heartbeats have crossed a whopping 2.75 billion beats. It’s no wonder that by the same age or older, one in eight people has moderate or severe aortic stenos which is a condition wherein the aortic valves of the heart toughen up and lose their flexibility, making it arduous for the heart to pump blood in an effective way.
This can lead to symptoms such as dizziness, feeling of faint, and chest pain, not to mention, it not only places a tremendous burden on the heart but also it greatly increases the risk of heart failure as well. Aortic valve repair surgery or aortic valve replacement is often suggested for these patients.
Normal reference for transcatheter aortic valve replacement with the balloon-expandable valve:
Tran catheter aortic valve replacement (TAVR) is a newer approach for treating aortic valve disease with minimalistic invasion. This procedure of replacement has expanded the possibilities for replacing the aortic valve, and there are continuous efforts to help shape its evolution further.
Mechanically, valves are expected to last the life of the patient. Valve is usually made of animal tissue and can last for 10 to 15 years or more if the patient is over 80 years of age.
Currently, there are few valves which may last up to five years, without any signs of early degeneration. Those are for people who cannot afford to undergo surgery for a replacement of the valves; TAVR was first developed as an effective option where a need was felt but was lacking an option. Recently, it is the alternative for people who could choose an operation though not free of moderate risks. Off late, there have been researches which are being done to check the possibilities of its usage in more and more people.
Exercises also are a way to reduce the above cited problems When working with weight-bearing restrictions, the patient will likely be asked to walk with an assistive device like a cane, crutches, or a walker. The physical therapist usually demonstrates to the patients as to how he or she can use his or her assistive device and ensure that it is of perfect size for him and her as the case maybe.
Risks of TAVR:
With all the trials going on, done by experts, risks involved cannot be ruled out though they can be handled by the team concerned.
- Valve leakage: Few times, blood oozes out around from the new valve as the replacement fails to match the size, and fails to expand inside, or has any interference from the calcium which is inside the body. But this has seen light and , the patients have access to new, more effective models and many more are getting developed as we read this.
- Damage to the kidney: This treatment may damage the kidneys, though the problem can usually be repaired.
- Vessels can be damaged: When catheters pass through the arteries, they can damage the vessel. Again, this damage is usually repairable too.
- Strokes: A few people undergoing TAVR may encounter a stroke, either during or post the procedure.
- Vascular Complications: Vascular complications are mainly caused by the mismatch of access artery and encasements of delivery system.
- Pacemakers: When valves open during replacement, they can sometimes push on to the heart’s electrical system and this makes the need for the pacemaker. Newer models are developed to answer such questions.
With the improvements in the delivery systems, improvements in the patient evaluation required before the process and increased surgical experience, the vascular access-site complications have decreased in the recent past.
Having said that, when the conducting artery lumen is narrower than 6 mm with calcifications and despite all the developments, more improvements are needed.
In case of any complications, angiographic of the artery may be the urgent diagnosis method and an acute hypotension without other causes may also help the diagnosis of major arterial damage. Urgent endovascular or surgical repair is recommended for such cases.
TVAR surgery still needs more effectiveness process, although this process has high success rate with few surgical complications, but it still carries risk.
The scientific research in the field of medicine has allowed to treat patient with severe aortic maladies.
Issues includes vascular issue ventricular wall and perforation valve complications.
Still, lots of medically and technically research are going on to make this replacement most effective and less risky.
In the above blog, we can see that more number patients still need better treatments and surgeries who are still suffering.
As of now, most of the people having problem of heart choke and heart attacks are due to oil based food, junk foods and fast lifestyle which is affecting the arteries badly. The moment calls for a balanced and healthy life changes for mind, soul and body.
