Does supra-annular self-expanding THV reduce postprocedural mean gradient compared to balloon-expandable THV in patients undergoing aortic VIV replacement?
Supra-annular self-expanding THVs may offer better hemodynamics (lower mean gradient) than balloon-expandable THVs in aortic valve-in-valve procedures.
The supra-annular self-expanding THV was associated with a lower postprocedural mean gradient compared with balloon-expandable THV in patients undergoing aortic VIV replacement.
