valve and lower pulmonary valve annulus z-scores may be predictive of the need for subsequent RVOT reintervention.
Conclusion: Using these parameters might predict good survival of patients and anticipate the need for a subse- quent RVOT reintervention.

Objective: To present experience of endovascular proce- dures in newborns with hypoplastic left heart physiology.
Methods: Since 2012 to 2017yy. 15 patients with hypoplas- tic left heart physiology underwent hybrid procedures. All patients were newborns (1-9 days of life) in a critic condi- tion. Body weight comprised 2.24±0.14kg. Ascendig aorta dimensions < 2 mm.
All 15 patients underwent bi-lateral banding of pulmo- nary arteries combined with stenting of Ductus arteriosus. In 2 patients used self expandable stent; in 13 - balloon expandable stent. In 3 patients intervention completed with Rashkind procedure.
Results: 4 of 15 patients made an unevenrtful recovery; 11 - died. In-Hospital mortality comprised 73.3%. One patient three years later underwent favorable re-stenting of Ductus arteriosus.
Causes of mortality: septic complication - in 2 patients; stent & istmus of the aorta thrombosis with consequent coronary insu ciency - in 4; stenosis of stent with occlu- sion of istmus of the aorta - in 1; left atrium perforation during Rashkind procedure - in 1; bleeding - in 1; fatal car- diac rhythm disturbances - in 3 patients.
Conclusion: Despite of high mortality hybrid procedures are the only choice of option in newborns with hypoplastic left heart physiology in critic condition & serve like a bridge for following intervention
18. POST-DILATATION TO PREVENT STENT MAL- APPOSITION AND JAILING IN AORTIC COARCTATION AND PULMONARY STENOSIS

History and Physical:
Case 1: A 16-year-old boy with CoA. He previously under- went percutaneous stenting for recurrent CoA. The center of the rst stent had been placed at the most stenotic site, apposing the aortic wall and avoiding jailing of the left sub- clavian artery. Follow-up CT angiography revealed defor- mity of the descending aorta at the proximal site, which might have been caused by the protrusion of the primary stent against the posterior wall of the aorta. An additional stent in the proximal site was proposed to prevent aortic wall injury.
Case 2: A 11-year-old boy with hypoplastic left heart syn- drome. He underwent total cavopulmonary connection at the age of 2. Stenting(P3008) was performed for postop- erative central PS at the age of 9. The proximal end of the stent protruded over the SVC anastomosis. Post-dilatation for the protruded part was proposed to prevent obstruc- tion of systemic venous ow.
