The first TAVI was performed on 16 April 2002 by Alain Cribier, which became a new alternative in the management of high-risk patients with severe aortic stenosis.
[2][3] The implantated valve is delivered via one of several access methods: transfemoral (in the upper leg), transapical (through the wall of the heart), subclavian (beneath the collar bone), direct aortic (through a minimally invasive surgical incision into the aorta), and transcaval (from a temporary hole in the aorta near the navel through a vein in the upper leg), among others.
[5] In patients who are deemed too high risk for open heart surgery, TAVI significantly reduces the rates of death and cardiac symptoms.
[9] Medtronic's CoreValve Transcatheter Aortic Valve is constructed of a self-expanding Nitinol (nickel titanium) frame and delivered through the femoral artery.
St Jude Medical's Portico Transcatheter aortic valve received European CE mark approval in December 2013.
[12] Edwards' Sapien aortic valve is made from bovine pericardial tissue and is implanted via a catheter-based delivery system.
[17][18] In the subclavian approach, an incision is made under the collarbone under general anesthesia, and the delivery system is advanced into the correct position in the aortic valve.
[19] New or worse post-procedure symptoms that require attention include dizziness or light-headedness, swelling of the ankles, sudden weight gain, extreme fatigue with activity, and signs of infection.
Emergency attention is required for chest pain, pressure or tightness, severe, sudden shortness of breath, or fainting.
[19] When PAVR surgery is performed an important and difficult aspect that affects the patient is the orientation, uniformity and depth at which the valve is inserted.
The results showed that while the two PVL cases worsened the fluid dynamics of the normal transmitral flow seen without leakage, the posterior orifice PVL was worse, leading to a higher circulation and kinetic energy, requiring the heart to work harder and consume more energy to maintain normal bodily functions.
Additionally, the "Big 5 of TAVI complications" include paravalvular leakage (PVL), major bleeding or vascular complications, acute kidney injury (AKI), stroke, and conduction abnormalities, such as high-degree AV-block with need for permanent pacemaker implantation must be monitored to ensure successful procedural outcomes such as low mortality and morbidity.
[24] Whereas clinical stroke is associated with reduced quality of life and cognitive impairment, the significance of silent brain infarcts and elevated levels of neurofilament light is presently unclear.
[26] The durability of transcatheter prostheses, in terms of all-cause mortality and the need of re-intervention, was not reliably known as of 2021[update] due to the lack of long-term follow-up data.
A narrative review published in 2021 reported that a 2015 study involving simulation on first-generation prostheses suggested a TAVI durability limited to 7–8 years.
The 2021 review suggested that in younger patients (with longer average life expectancy) choosing TAVI might still be premature, due to the increased likelihood of the need for future re-operation with worse prognostic impact.
[27] The catheter procedure was invented and developed in Aarhus University Hospital Denmark in 1989 by Henning Rud Andersen,[28] who performed the first animal implantations that year.
[citation needed] Internationally famous pop singer Mick Jagger had the procedure in March 2019 at NewYork–Presbyterian,[34] which was said to have raised public awareness.
