Why the study?
Paravalvular leakage is a well-recognized complication of prosthetic valve replacement, prompting the introduction of a new technique using a folding pericardium patch to avoid a second-time valve replacement.
Does a folding pericardium patch technique improve the management of intraoperative paravalvular leakage in patients undergoing prosthetic valve replacement?

A novel folding pericardium patch technique provides a viable alternative to second-time valve replacement for managing intraoperative paravalvular leaks.
May offer an alternative in select intraoperative paravalvular leaks; leaves open need for prospective validation before adoption.
Paravalvular leakage (PVL) is one of the most well-recognised complications of prosthetic valve replacement. The size of the leakage is usually about one to two stitches. We would like to introduce a new technique to manage this complication by using a folding pericardium patch, which can surely overcome the disadvantage of second-time valve replacement. By now, we have applied this new technique to at least four cases, all of them worked well. Thus, we present our new technique that can be considered as a good alternative management of intraoperative PVLs, especially in aortic position.
