Fetal cardiac intervention and fetal cardiac surgery: where are we in 21st century?

Fetal cardiac intervention is an in-utero cardiac procedure done in fetuses with heart diseases like severe aortic stenosis with evolving hypoplastic left heart syndrome, hypoplastic left heart syndrome with an intact or restricted atrial septum, pulmonary atresia with an intact ventricular septum, fetal heart block obstructed total anomalous pulmonary venous return, pericardial collection. The successful biventricular repair can be done in postnatal life after aortic or pulmonary valvuloplasty. Fetal bypass is very challenging because of different physiology. Low prime volume with the high flow can be used to prevent an inflammatory response.

Type II aortopulmonary window with tetralogy of Fallot: successful repair.

Aortopulmonary window associated with tetralogy of Fallot is a rare cardiac anomaly. An 8-month-old boy presented with failure to thrive and recurrent chest infections. Echocardiography and imaging studies revealed a type II aortopulmonary window with tetralogy of Fallot. Corrective surgery in the form of patch closure of the aortopulmonary window and intracardiac repair of tetralogy of Fallot was carried out successfully.
