SUMMARYTGA AND LVOTO

SUMMARY• Surgical Results Good – Low Mortality, Similar To

TGA/VSD• TGA/VSD Or TGA/IVS With Isolated PV

Abnormality – ASOTGA/VSD/IVS With S b al ar Obstr ction Choice Of• TGA/VSD/IVS With Subvalvar Obstruction – Choice Of

Operation Varies Based On Resectability Of LVOT, PV Annulus Size

• Nikaidoh-Bex Useful For VSD/PS With Moderate PV Hypoplasia Or Septal Malalignment

• Rastelli/REV For Pulmonary Atresia, Significant Valvar y , gPS And Hypoplasia –REV May Have Less Reop

• Results With Rastelli Suboptimal – LVOTO & Conduit Changes CommonChanges Common

• Late Function Of AV And Root Still Unknown

TGA AND LVOTO

QUESTIONSQUESTIONS• When is PV too small for ASO?• What is long-term function of bicuspid PV?• Is the fate of the AV and root same as in Ross

operation?• Is the aortic valve at more risk for late AR after aorticIs the aortic valve at more risk for late AR after aortic

translocation?• Is coronary transfer with aortic translocation

i t d ith l t l i / t i ?associated with late occlusion/stenosis?• Is the REV operation associated with less LV

dysfunction and recurrent LVOTO than the Rastelli?

• Is VSD enlargement technique at Rastelli or REV associated with long-term survival?associated with long term survival?

• Will REV patients all require PV implantation late?
