You say there is no way for the condition to be buyable postnatally without viable without a vsd, but I was under the impression that Pda a good shot blood to the lungs if there was no vsd . Is that not correct?

You're absolutely right! I stand corrected! I should have said that both an ASD and another shunt are necessary, rather than specifying the VSD. After all, we may find intact ventricular septum in Type Ia Tricuspid Atresia (with pulmonary atresia). "In some cases where a VSD is not present or there is significant pulmonary obstruction, the patient is reliant on a patent ductus arteriosus (PDA) to enable blood flow into the pulmonary circulation." (Sumal, AS, Kyriacou, H, Mostafa, AMHAM. Tricuspid atresia: Where are we now? J Card Surg. 2020; 35: 1609- 1617. doi.org/10.1111/jocs.14673) "In patients who have normally related great arteries and no VSD, there is pulmonary atresia, and hence blood supply to the lungs depends on a patent ductus arteriosus (PDA). In type Ia, blood from the right atrium is shunted across the atrial septum to the left atrium and then across the mitral valve into the left ventricle and out the aorta to supply blood to the body and also through the PDA to the lungs." (Minocha PK, Phoon C. Tricuspid Atresia. [Updated 2021 Sep 28]. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2021 Jan-. Available from: www.ncbi.nlm.nih.gov/books/NBK554495/) What a great comment!

By the way, I have a more recent video on Tricuspid Atresia ( kzfaq.info/get/bejne/aLF0rLKQ073JiXU.html )! (albeit with the same mistake...)
