Transcatheter Aortic Valve Implantation (TAVI)
Step-by-Step Procedure for Transcatheter Aortic Valve Implantation (TAVI)
Pre-procedural Evaluation
Anesthesia and Access
Guidewire Placement and Valve Delivery
Valve Deployment
Assessment and Closure
Before the procedure, an extensive evaluation is conducted to assess the patient's condition. This includes a series of tests such as echocardiograms, CT scans, and angiograms to determine the suitability for TAVI.
The procedure begins with the administration of anesthesia. Typically, the entry point for TAVI is either the femoral artery (transfemoral approach) or through a small incision in the chest (transapical or transaortic approach).
Once access is established, a guidewire is threaded through the arteries to the heart. Using advanced imaging techniques like fluoroscopy and echocardiography, the delivery catheter containing the collapsed replacement valve is guided to the site of the diseased valve.

Minimal Invasive Heart Valve Replacement Cost
Open Heart Valve Replacement Cost
TAVI Cost
₹3,00,000 - ₹4,00,000
₹3,50,000 - ₹5,00,000
₹15,00,000 - ₹25,00,000
Transfemoral Approach
This is the most common approach where access is gained through the femoral artery in the groin. It's favored for its minimally invasive nature and quicker recovery.
Different Approaches and Techniques in Transcatheter Aortic Valve Implantation (TAVI)
Transapical Approach
In cases where the femoral artery approach isn't feasible, access can be gained through a small incision in the chest wall (transapical) or through the aorta (transaortic).
Tools and Advancements in Transcatheter Aortic Valve Implantation (TAVI)
Valve Designs and Materials
Constant advancements in valve designs and materials contribute to enhanced durability, better hemodynamics, and reduced complications.
Imaging and Navigation Technologies
High-resolution imaging technologies like 3D echocardiography and advanced navigation systems aid in precise valve placement, ensuring optimal outcomes.
Miniaturization and Delivery Systems
Ongoing developments focus on miniaturizing delivery systems, making the procedure less invasive and improving patient comfort.
Transcatheter Aortic Valve Implantation (TAVI) has evolved significantly, offering a promising alternative for patients with aortic valve disease. With continuous advancements in techniques, tools, and approaches, TAVI continues to redefine cardiovascular care, providing new hope and improved outcomes for patients worldwide. As technology progresses, the future of TAVI holds even greater potential in transforming cardiac interventions.
Remember, while TAVI showcases immense promise, it's crucial to consult with healthcare professionals to determine the most suitable treatment plan based on individual medical circumstances.
