New to the group with some back hx

Hi and thanks for the add. I was born with hemitrunkus which was repaired when I was 8 days old back in 1976. In 1984 I had ASD repair. I lived a pretty normal life. Had kids via c sections no complaints by me at all. in 2015 I had a pulmonary artery sent put in and now in 2017 as of a few weeks ago I was diagnosed with Pericarditis. I am trying to figure out where the connection is with all of these issues. If anyone can help I would be so grateful
