Mitral valve Atresia

[Agreya]

My daughter who is 11 yr age now was born with DORV,mitral atresia and when she was 1 month old BAS was done and within a week after that PA Banding was done . at the age of 9 months she underwent BD Glenn which was not tolerated because of high PA pressures so glenn was taken down and septostmy was done . Upto 5 yrs of age ahe was just on the same procedure no surgery was undertaken because of high pressures again and she has strted detoriating so an attempt was made for glenn shunt again which again was complicated  due to same reasons again she swelled up and for about 29 days was on ventilator support because her lungs were bleeding  but somehow they could manage the condition.

when she was 8and half yr an attempt was made to complet the fontan and when she she was taken for surgery surgeon could not undertake it same reason high pa pressures and she has collateral veins so some of them were coiled and left to right shunt was done which was 6 mm which have improved her saturation but now again her saturations are dipping  and doc  is suggesting again for fontan and next week they are going to do angigraphy to dtermine her PA pressures . pls suggest what can be the possibilities for her.
