A new technique of managing paravalvular leak using a folding pericardium patch

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Surgical Techniques

Background:

• Paravalvular leakage (PVL) is a known complication following prosthetic valve replacement surgery.
• Current management strategies may involve repeat valve replacement, which carries significant risks.
• Small to moderate PVLs, often sized one to two stitches, present a specific challenge.

Purpose of the Study:

• To introduce and evaluate a new technique for managing intraoperative paravalvular leakage.
• To present a less invasive alternative to re-operation for PVL.
• To demonstrate the efficacy of a folding pericardium patch for PVL closure.

Main Methods:

• Development of a novel surgical technique utilizing a folding pericardium patch.
• Application of the technique in patients experiencing intraoperative paravalvular leakage.
• Focus on cases involving the aortic valve position.

Main Results:

• The folding pericardium patch technique was successfully applied in at least four cases.
• All treated cases demonstrated positive outcomes, indicating successful closure of PVLs.
• The technique proved effective in managing intraoperative PVLs without necessitating re-operation.

Conclusions:

• The folding pericardium patch technique offers a viable and effective solution for intraoperative paravalvular leakage.
• This method presents a significant advantage by avoiding the need for a second valve replacement.
• It is a promising alternative management strategy, especially for PVLs in the aortic position.
