TAVI involves implanting a prosthetic valve within the diseased aortic valve using a catheter-based approach, typically through the femoral artery in the groin or through a small incision in the chest. The new valve is expanded and positioned within the existing valve, restoring proper blood flow and relieving symptoms associated with aortic stenosis.
Preparation: Before the procedure, the patient undergoes a comprehensive evaluation, including imaging tests and cardiac assessments, to determine eligibility for TAVI.
Anesthesia: Local anesthesia or conscious sedation is administered to ensure the patient is comfortable during the procedure.
Catheter Insertion: A catheter with the collapsed prosthetic valve is inserted into the femoral artery or another access site and guided to the heart.
Valve Placement: Once in position, the new valve is expanded and positioned within the diseased aortic valve using balloon inflation or self-expanding mechanisms.
Assessment and Adjustment: The placement and function of the new valve are assessed using imaging techniques such as fluoroscopy and echocardiography. Adjustments may be made as needed to ensure optimal positioning and function.
Closure: After confirming proper valve placement and function, the catheter is removed, and the access site is closed with sutures or a closure device.
Minimally Invasive: TAVI offers a less invasive alternative to traditional open-heart surgery, resulting in shorter hospital stays, faster recovery, and reduced risk of complications.
Effective Treatment:TAVI effectively relieves symptoms of aortic stenosis, improves heart function, and enhances quality of life in eligible patients.
Suitable for High-Risk Patients: TAVI is suitable for patients considered high-risk or ineligible for traditional open-heart surgery due to factors such as advanced age, frailty, or comorbidities.
Improved Outcomes: Clinical studies have demonstrated comparable outcomes between TAVI and surgical aortic valve replacement in terms of mortality and symptom relief.
Medications: Medications to prevent blood clots and manage symptoms may be prescribed following the procedure.
Follow-Up Care: Regular follow-up appointments with a cardiologist are essential to monitor valve function and overall heart health.
Transcatheter Aortic Valve Implantation (TAVI) is a groundbreaking procedure that has revolutionized the treatment of aortic valve stenosis. Offering a less invasive alternative to traditional open-heart surgery, TAVI provides effective symptom relief, improved heart function, and enhanced quality of life for eligible patients. By understanding the procedure, benefits, and recovery process of TAVI, individuals can make informed decisions about their cardiovascular health and treatment options.
