Fluoroscopic Parameters for Each of the Study Subgroups

NL (n = 42)PPM (n = 32)AVPO (n = 26)
Opening angle, °17 ± 519 ± 554 ± 18
Closing angle, °129 ± 9131 ± 7124 ± 13

Values are mean ± SD.

AVPO = aortic valve prosthesis obstruction; NL = normal aortic prosthesis; PPM = prosthesis-patient mismatch.

  • p < 0.05 versus NL, and

  • p < 0.05 versus PPM by analysis of variance for independent samples with post hoc comparison (Dunnett's T3 method).
