I just learned that there are two kinds of patches for the PDA surgery - artificial patch and the human tissue patch.
When did they start the new patch (out of human tissue) for PDA - Patent Ductus Arteriosus during heart surgery for humans? When did they start the newest kind of patch - which is the human tissue - to place over the hole of the heart?
The reason I asked is that in December 1969, I was a month old, I had PDA surgery to repair a large PDA with a patch. I have been told by a cardiologist in 1991 that the patch is still holding on.
Today, I was told that artificial patch for a PDA requires antibiotic treatment before dental work, where the newest patch for PDA with human tissue, you do not have to have antibiotic treatment before you go to the dentist. The nurse said since it was in 1969 or 1970, it's highly likely my heart patch was artificial so I need antibiotic treatment before I go to the dentist.
