The transcatheter aortic valve replacement involves implanting a synthetic valve by removing the affected aortic valve. The replacement of the natural aortic valve is necessary due to stiffness and blockages caused due to aortic stenosis.
The synthetic aortic valve in TAVR regulates the normal blood flow of the heart. The replacement becomes necessary since the aortic valve present inside the heart fails to transfer the blood.
Being surgical, TAVR is often referred to as surgical aortic valve replacement. Aortic stenosis may result in heart failure since it affects the valve. However, TAVR helps in overcoming such complicated cases.
