[|Human|] Hello... My brother , 18 yrs of age has a complex CHD: Dextrocardia, Common Atrium (single AV Valve) and unbalanced ventricles he already had a BT Shunt in 92 and BDG in 94. He is presently on Acitron, Listril and Lasilactone... I need some advice on this...
[|AI|]  Hello dear, your brother is having a complex chaotic congenital heart disease with probably single ventricular physiology and reduced pulmonary blood flow. This usually needs multiple surgeries and single ventricle repair in which the single functional ventricle is made systemic and the venous flow is diverted directly to Pulmonary arteries.That's why he underwent BT shunt for optimizing pulmonary blood flow. And then BDG as a first stage of Fontana repair in which the SVC is connected to Pulmonary artery. Now usually this is followed by another surgery in which the IOC is also connected with the Pulmonary artery and this is generally done at the age of 10-12 years. But in your brothers case, this is not done. May be because the unbalancing of the ventricles was not that severe and one of the ventricles was able to handle at least half of the venous flow. This is called as hemi-Fontan surgery. Please show your brother to a pediatric Cardiologist and get a detailed echo to see the functioning of BDG shunt and also the native ventricles and valves. Now because he underwent BDG, he needs to be on oral anticoagulation in the form of citron. Hope this would help you.
