trans catheter aortic valve implantation (tavi)

What is the trans catheter aortic valve implantation (TAVI) procedure?

TAVI standards for trans catheter aortic valve implantation. If a patient needs to undergo an aortic valve replacement and isn't physically fit to undergo a surgery, then they are given a Tavi procedure. It is performed when the aortic valve does not contract and expand properly.

the blood vessels (coronary arteries) that are responsible for supplying oxygen and nutrients to the heart muscles. This leads to narrowing of the coronary arteries. During the procedure, the doctor surgically connects a healthy blood vessel from your leg, arm or chest to the heart and creates a new pathway around the blocked or the partially blocked artery to restore blood flow.

How does trans catheter aortic valve implantation (tavi) help?

This method of treatment is revolutionary as for the first time the doctors have been able to treat an aortic valve disease with the help of a catheter and not a surgery. It reduces the stress on the heart thereby increasing cardiac output. 

How is trans catheter aortic valve implantation (tavi) done?

The first step of diagnosis is a basic physical examination to understand the symptoms, family history,
medical history, and an understanding of the overall health of the person.
Preparation
Treatment Procedure
Post Treatment
 

Initially the doctor advises the patient to maintain a healthy diet and keep a track of their symptoms. If the patient starts losing weight without trying a few medications are suggested. Full body scans are carried out to ensure that the major arteries are not blocked.

 

This treatment plan is suggested for patients with severely calcified aortic valves. In this a wire is put through the aorta into the left ventricle of the heart through the calcified aortic valve. Following that a balloon catheter is passed over the wire into the valve to open the valve. Then the trans catheter valve is inserted in the opened aortic valve. This allows the world to function properly.

 

After the implantation the doctors keep the patient under observation for a few days. An antithrombotic therapy is suggested to prevent thrombotic complications.

Causes

Alcohol and tobacco use (including smokeless tobacco, sometimes called “chewing tobacco” or “snuff”) are the two most important risk factors for head and neck cancers, especially cancers of the oral cavity, oropharynx, hypopharynx, and larynx. Following are the causes of Head and Neck Cancer:

Benefits
Risks
Limitations
  • Improve mortality rates
  • Left ventricular haemodynamics and remodelling
  • Improves the quality of life
  • Reduces pain in cardiac tissue

 

  • Bleeding
  • Blood vessel complications
  • Valves might slip or leak.
  • Heart attack
  • Kidney disease
  • Stroke
  • Infection
  • Patients might show adverse effects like vascular complications and the need for pacemaker implantation.
  • Patients may also show paravalvular regurgitation.
  • This method is dicey for aged patients.
