TAVI
Pronunciation: TAH-vee
Also written as: TAVI — Transcatheter Aortic Valve Implantation
Transcatheter aortic valve implantation, a minimally invasive procedure to replace stenotic aortic valves.
Full Definition
A percutaneous procedure for treating severe aortic stenosis by deploying a bioprosthetic valve via catheter-based delivery, typically through femoral, subclavian, or direct aortic access. TAVI has revolutionized treatment for high-risk surgical patients and is increasingly used in intermediate and low-risk populations. The procedure requires specialized anesthetic management, often performed under conscious sedation or general anesthesia with careful hemodynamic monitoring. Anesthetic considerations include managing rapid ventricular pacing during valve deployment, potential complications such as heart block or vascular injury, and transition from severely stenotic to competent valve function.
Usage
Usage note: TAVI and TAVR are used interchangeably, though TAVI is more common in European literature.
