Mediastinal adhesion of RV-AP tube to the sternum.
Levocardy, situs solitus, PVR normal, systemic veinous return normal, atrioventricular concordance, ventriculoarterial discordance in D-loop (LV-MPA and RV-Aorta).
VSD was non-committed to outflow tracts and has been closed during the Rastelli procedure.
Right outflow tract:
Enlarged RV.
RV-PA conduit 12x21mm 174mm² with post-conduit dilation of MPA, left PA and right PA.
Left to right shunt due to native hypoplastic MPA which is still permeable. (Mitro-pulmonary continuity due to D-loop)
Left outflow tract:
Subaortic stenosis (217 mm², 14x20mm) followed by sinus ectasia 44x48x46 mm and tubular dilation 44x50mm. Tricuspid aortic valve.
Coronary ostia anomalies:
- from the posterior sinus arises the Cx
- from the right sinus arises the LAD and RCA with a common ostium.
LAD courses between the conduit and aorta. - left sinus: non coronary sinus
Right dominance, no coronary stenosis nor aneurysm.
No other anomalies (bronchi, lungs, liver) (not shown).
