ABSTRACT
Aortic prosthesis-patient mismatch (PPM) has been registered
and logged as one of the most powerful predictors
for poor prognosis at a long-term follow up after aortic
valve replacement. New and more recent prosthtetic
models have reached such a perfection that the obtained
gradients are increasingly lower. Such is the case between
the 19 mm monostrut mechanical aortic heart valve and
SJM Regent (0.8 cm2 vs 1.6 cm2, respectively). We show
one case herein about a female patient underwent mitral
and aortic mechanical replacement plus tricuspid annuloplasty.
Over 19 years, she developed impairment in
NYHA funcitonal class III. Important patient-prosthesis
mismatch was identified. With no other alternative than
simple re-replacement (because of the mitral prosthesis
in situ), the 19 mm monostrut mono-leaflet prosthesis
was taken away and a 19 mm bileaflet SJM Regent was
inserted instead of. Patient course was uneventful with
no important gradient or any mismatch aortic valve-relate.
Patient prosthesis relationship highly improved
from 0.47 up to 0.94. This simple case illustrates very well
how important is the preliminary calculation of the patient-
prosthesis match befofe operation.
