Selection of the implanted PH:
The size of the implanted PH was determined with the body surface and
the recipient age, following the Rowlatt table (range -2 <
Z-Score < +2) [8]. PH were systematically oversized when
implanted in young patients to provide acceptable hemodynamic
performances at the end of growth. There was no patient – donor
matching in terms of ABO group and Rhesus type.
