Durability of TAVI valve
Successful replacement of heart valve can fail due to several reasons including the formation of calcium deposits on valve leaflets resulting in stiffening, seeping of cholesterol into valve tissues, mechanical stress on valves, or contribution of immune response accelerating damage of the valve. Due to the difference in the original and bio-prosthetic valves, these conditions occur. The option to treat such a condition is to get the valve replaced with a new one or the new option of minimally invasive valve-in-valve or TAVI.
It is located between a big artery carrying blood to the lungs called the pulmonary artery and the right ventricle. This process is essential for the oxygenation of blood to supply oxygenated blood to vital body organs.
WHAT IS TAVI?
Transcatheter Aortic Valve Implantation (TAVI) or transcatheter aortic valve replacement (TAVR) is a surgical procedure requiring very little invasion. This procedure involves placing a new valve inside the old and diseased valve without removing it
Since the introduction of TAVI, the procedure has benefitted almost 300,000 patients both in terms of enhanced quality of life and life expectancy. TAVI has been recommended for patients considered to be high surgical risk and those patients having specific conditions favoring TAVI
IS THE PROCEDURE OF TAVI DURABLE?
The durability of the valve becomes a paramount feature when TAVI is considered to be used. A study conducted studying the ten-year follow-up after a TAVI procedure found that bioprosthetic valve failure (BVF) and structural valve deterioration (SVD) after TAVI were reported to be very less (4). It is also helpful to know that scientific evidence suggests that in patients with a mean age of seventy years, the rate of survival of TAVI is greater than 55% whereas the chances of survival look much better in younger patients between the age of sixty to seventy years when there are no complications in surgery. After 10 years, the rate of re-operation of the heart valve, death, and clinical investigation is only 10%.
BENEFITS OF LONG-TERM DURABILITY OF TAVI
The durable TAVI procedure has several acknowledged benefits including a better mortality rate, improved remodeling, hemodynamics of the left ventricle, and quality of life. The innovative technology used in the device reflects the significantly reduced peri-procedural mortality as well the increased rate of survival after the TAVI procedure. In addition, the safety of TAVI has been validated without any damaging effects on the hemodynamic of the prosthesis.
In elderly patients, TAVI has an important goal to improve their functional status and with controlled exercise after TAVI procedure, the danger of falls lowers in elderly patients. This decreases the chances of comorbidities due to bone fracture and increases the chances of home discharge. Moreover, the longer durability increases the quality of life because of proper working of heart valve patients have reported to have more energy, experience less pain, and breathe normally.
Keeping in view all the benefits and the durability of the TAVI, this interventional procedure can help to maintain the health of the heart valve and if you are in search of a clinic for TAVI in Mumbai, The Valve Clinic has an expert team specialized in comprehensive care for TAVI.
