Valve Repair with Newer Methods
Our heart comprises of different components and heart valve is one of them. It plays a vital role in normal functioning of the heart. There are four valves present in the heart which helps the blood in flowing in the right direction. But in some of the cases, one or more of the valves don’t open properly. There might also be an issue in closing of the valve. This causes disruption in normal blood flow to the body through the heart. This is known as structural valve disease. The treatment which is imparted depends on the valve which is affected and the severity of the disease. Sometimes, there is need of surgery and one of the most effective in treating heart valve disease is Transcatheter Aortic Valve Replacment (TAVR) or Transcatheter Aortic Valve Implantation (TAVI).
TAVI is a minimally invasive surgical procedure in which valve is repaired and the diseased valve is kept in place. This aortic valve is implanted with the help of a long narrow tube called a catheter. This type of a surgery is different from the standard valve replacement procedure and it is approved for people with symptomatic aortic stenosis but won’t be able to sustain an open heart surgery. Patients who are in their 70’s or 80’s are considered as the ideal candidates.
There are different causes which can lead to this problem. Some of them are –
1. There may be calcium buildup on the valve’s cusp as blood repeatedly flows over the aortic valve.
2. Degenerated or deformed valve tissue.
3. High blood pressure which can lead to heart attack.
4. Bacterial endocarditis and rheumatic fever also can cause rupture of the aortic valve.
The symptoms of heart valve disease are given below –
1. Murmuring of heart when a doctor listens with a stethoscope.
2. Fatigue due to no particular reason.
3. Irregular heartbeat.
4. Shortness of breath.
5. Dizziness or fainting.
The procedure of TAVI is done through very small openings. All the chest bones are left in place. This procedure has its own set of risks and the hospital stay is around 3-5 days which is lesser than open heart surgery. In this procedure, transapical approach is made and entry is done through a large artery in the chest or through the tip of the left ventricle. This left ventricle is also known as the apex.
