Procedural success was obtained in 100%
2011-07-25
Procedural success was obtained in 100% of the
valve-in-valve patients, with no periprocedural death. There were no
cases of valve deterioration or new onset of central or perivalvular
regurgitation observed or any reports of thrombotic or embolic events in
the valve-in-valve group, "which reflects well on the design features
and the endothelialization of the [CoreValve] device," according to the
authors.There were no major adverse
cerebrovascular and cardiac events within 30 days for the patients
undergoing the a second safety valve implant
"The valve-in-valve technique can be used
readily in the catheterization laboratory as bailout therapy for a
failed implantation resulting from a malpositioned valve with severe
paraprosthetic leak when the attempt of reposition with the snare
technique fails, preventing conversion to emergency open-heart surgery,"
the authors explain. "The availability of a bailout provides a margin
of safety and enhances operator confidence. This is important for a
nascent technology like TAVI to gain widespread clinical acceptance."
This margin of safety is important because which patients will develop a
leak is difficult to predict prior to their initial valve-replacement
procedure, Ussia told heartwire.
