Paravalvular Leak.

Methodist Debakey Cardiovasc J 2022 1;18(1):7-9. Epub 2022 Apr 1.

Houston Methodist DeBakey Heart & Vascular Center, Houston, Texas, US.

Despite improvements and advancements in surgical technique, paravalvular leaks (PVL) continue to present a challenge when caring for patients with prosthetic valve disease. Paravalvular leaks result from dehiscence of the surgical ring from the mitral annulus. Some theories suggest that uneven distribution of collagen fibers in the mitral annulus leaves the posterior mitral annulus without a well-formed fibrous structure, which may predispose it to recurrent mechanical injury that leads to PVL.
