I have read the article entitled “ Innovative, Replaceable
Heart Valve: Concept, In Vitro Study, and Acute In Vivo Study” by
Fukamachi K et al, published in Artificial Organs 32(3):226–239.
I want to congratulate the authors for this successful article and
make some contributions.
In the article, it is indicated that in the first experiment
mitral annulus was too small for prototype #27, and the valve
was implanted in the supra-annular position, but the question
that comes to our mind is that does the supra-annular position
of the valve has any effect on post-implant complication like
paravalvular leakage, endocarditis, thromboembolism, and
mitral regurgitation [1-4]. And does the ability of the valve to
withstand the high left ventricular systolic pressure of 375 mmHg
without decoupling holds true in this case. What we would also
like to bring to your attention is the need for various sizes of the
implant to make sure that they fit anatomically . Additionally,
we would also like to define the inclusion or exclusion criteria
for patients that could be considered for this implant  and
whether if patients who previously have undergone mechanical
valve replacement would be measured on the same criterion.
Given the promising nature of this study, I wonder if the use of
the valves is considered in patients with Turner’s syndrome,
congenital bicuspid aortic valve and those with premature aortic
valve calcification [5,6]. At the end again we would like to thank
the authors for their valuable contribution and hope that our
observations are worthy of their attention.
