I think that you'll find that Cardiocel 3d is already specifically targeting neonatal patients:

From announcement on 2 May:

As there are virtually no flat surfaces in the vascular or cardiac structure, this unique 60 shaped collagen product targets complex neonatal arch and pulmonary artery repair and is intended to help optimize suturing of central and extra-cardiac shunts. Its dimensions and specifications are designed to ‘mate’ with the triple plane anatomy found in neonatal arch and pulmonary artery repairs.

I suspect that feasability studies to control thickness could also address the study results, as described in the webinar presentation:

§ Control of ADAPT® scaffold thickness:
First automated machine prototype complete
Processed a pericardium sheet from .5mm to .3mm
Processed a porton of a pericardium sheet as low as .15mm
Capability to produce two different thickness levels in same sheet
