transvalvulära

Transvalvulära (or transvalvular) is a term primarily used in the context of cardiology and refers to procedures or phenomena that involve crossing or passing through a heart valve. It is most commonly associated with interventions such as transvalvular catheter-based procedures for the treatment of valvular heart diseases, including transcatheter aortic valve replacement (TAVR) and other minimally invasive techniques designed to repair or replace malfunctioning heart valves.

In the context of cardiology, transvalvular procedures typically involve the passage of devices, catheters, or surgical instruments through a heart valve to access the affected area. For example, in TAVR, a new valve is delivered through the vasculature and navigated across the diseased aortic valve to be deployed within the native valve structure. This approach is advantageous in high-risk surgical patients, reducing the need for open-heart surgery.

The term can also be used to describe blood flow or pressure gradients across a valve, where "transvalvular" indicates the direction of blood flow through a specific valve, often measured to assess the severity of stenosis or regurgitation.

Overall, transvalvulära procedures have gained prominence because they offer less invasive options for managing valvular heart disease, improving patient outcomes and recovery times. Advances in imaging and device technology continue to expand the applications and efficacy of transvalvular interventions.
