endovascular
Referring to procedures performed inside blood vessels using catheters and guidewires rather than open surgical techniques.
Full Definition
Endovascular techniques involve accessing and treating cardiovascular pathology from within blood vessels using minimally invasive catheter-based approaches. These procedures are performed through small arterial access points, typically the femoral, radial, or subclavian arteries. Common endovascular cardiac interventions include angioplasty, stent placement, valve replacement (TAVR), and device closure of septal defects. The endovascular approach often reduces procedural risk, shortens recovery time, and expands treatment options for high-risk patients. However, anatomical constraints and device limitations may preclude endovascular treatment in some cases, necessitating conventional surgery.
Usage
Usage note: Often used interchangeably with 'percutaneous' in cardiac contexts.
