Importance of implant technique on risk of major paravalvular leak (PVL) after St. Jude mechanical heart valve replacement: a report from the Artificial Valve Endocarditis Reduction Trial (AVERT)☆
Why the study?
Does valve suture technique without pledgets increase the risk of major paravalvular leak compared to technique with pledgets in patients undergoing mechanical heart valve replacement?

Implication
May warrant pledget use to lower major PVL after mechanical valve replacement; leaves open need for randomized confirmation.
