Surgeries for complex congenital heart defects

1. Surgeries of Hypoplastic Left Heart Syndrome,
Tricuspidatresia and Pulmonary atresia .
Hypoplastic Left Heart
Syndrome (HLHS)

2. Thisdefect is not correctable, but some babies can be
treated with a series of operationsor heart transplantation.
The surgical correction made in stages is referred as
Norwood procedure, allowsthe right ventricle to pump
bloodto the lungs and also to the body. It should be made
by reconstruction of aortic arch, and by Blalock– Taussig
shunt or Sano Shunt, (shunt between right ventricle and
pulmonaryartery)

3. The second stage (bidirectionalGlenn) is usually performed
between 4 -12 month.

4. The third stage lateral Fontanor extracardiac Fontan is
made between 18 month and 3 years of age.

5. Tricuspid atresia

6. There is no tricuspid valve so bloodcannot flow from the
right atrium to right ventricle. As a result the right ventricle
is small and not fully developed.
The corrective surgery is performed in three stages. The
first stage could be Blalock-Taussig shunt when the
tricuspid atresia is associated with pulmonary stenosis.

7. Pulmonary band in others cases without pulmonary
stenosis.
.
The second stage is performed with the bidirectional Glenn.

8. The third stage is made with extracardiac Fontan.

9. Pulmonary Atresia

10. There is not pulmonaryvalve, then the blood cannot flow to
pulmonaryartery.
Pulmonary atresia with intact septum
The surgery is also made in stages.
First stage is performed with Blalock-Taussig shunt or Brock
surgery (opening of the pulmonaryvalve)
Second stage  bidirectionalGlenn
Third stage  extracardiac Fontan

11. Pulmonary atresia with ventricular septal defect
Rastelli surgery ( Tube between right ventricle and
pulmonaryartery)
Ventricularseptal defect shouldbe closed
