Hi. I'm Marie-Jo, and this is Between the Beats.
I'm the mom of a daughter with a complex congenital heart defect. She was born with tricuspid atresia, she's had two open-heart surgeries, and she lives with what's called a Fontan circulation. If you know, you know. If you don't, that's OK too; you're in the right place.
When Aveline was diagnosed, I did what a lot of us do: I Googled. I read. I asked questions. And then I hit a wall. The research was out there, but it was locked behind jargon and paywalls and 47-page PDFs that assumed I had a medical degree. The parent forums were full of heart and a boon when I desperately needed support, but light on science. And the space in between (the place where someone takes the actual peer-reviewed evidence and explains it like a human being) didn't really exist. And I really needed that, too.
So I built it.
I come at this from a bit of a different angle. While I became a full-time CHD parent (if we're being honest, that's its own career), I also spent 25 years in project finance consulting and multilevel risk analysis. I have 3 master's degrees (all collecting dust in a drawer somewhere).
I am not intimidated by dense research papers; I'm trained to pick them apart.
And when I started reading the cardiology literature with those same analytical eyes, I kept finding the same thing: families like mine weren't getting the full picture - in English OR French. Not because their doctors were withholding it, but because nobody was translating it and making actually useful for everyday life!
Between the Beats is that translation. I read the journals, I dig into the studies, I check the math, I read between the lines, and I ask the questions you'd ask if you had the time and the access. And then I write it up in a way that respects your intelligence without assuming you have a PhD.
So this page is for fellow CHD families — parents, caregivers, the grown-up heart warriors, the people who love them. It's for anyone who's ever sat in a cardiology waiting room and thought: I wish someone would just explain this to me.
Pull up a chair. I'm glad you're here. 🫀
