Why the study?
Does a PTFE patch closure of the aortic valve correct aortic insufficiency in patients undergoing HeartMate LVAS insertion?
Does a PTFE patch closure of the aortic valve correct aortic insufficiency in patients undergoing HeartMate LVAS insertion?
PTFE patch closure of the aortic valve is a successful and inexpensive alternative to aortic valve replacement for managing aortic insufficiency during LVAS insertion.
PTFE patch may offer low-cost AI correction at LVAS insertion; leaves open randomized durability comparison to replacement.
A PTFE patch sewn to the aortic valve and annulus, to occlude the ventriculoaortic junction is used to successfully correct aortic insufficiency with HeartMate (LVAS) insertion. This represents an inexpensive alternative to aortic valve replacement for aortic insufficiency or the presence of a mechanical aortic valve.
