As I think you know, my ASD was randomly/luckily found in Dec 2009. I was asymptomatic. I was fit going into surgery and came out with the same fitness level. Basically my surgeon and I talked about it before. The debate being whether to wait or get on with it. He left the decision in my shoes and for me, I just wanted to know it was done and dusted and that I could get on with the rest of my life (at the age of 34). For the 12 months post surgery, I had a great awareness for my heart rate - resting, peak etc but now I don't think about it at all. I even wore my heart monitor in the steam and sauna room at my gym.
To answer your question, I was always fit and I am as fit as I was pre surgery and my heart and body feel strong as ever.
Listen to your body.
Please feel free to ask me anything.
Thanks John. Amazing that you did a marathon that soon and really had an admirable time. Thats really inspirational. Did you feel a dramatic difference in your stamina?
I had my ASD closed via robotic open heart surgery in May 2010 at the age of 34 years. I was back in the gym three weeks post surgery as soon as I got clearance from my surgeon. I eased into training and the final sign off came for going full tilt was at two months. Basically I was told to swim a few laps of the pool and then stand up and try to walk out of the pool (carefully out of the pool). This tests how well my could go from swimming (horizontal) to then go vertical. My body reacted fine and I was given full clearanc to do anything. Less than six months post surgery, I ran the NY City Marahton in 3hrs 36 mins. I was lucky I never felt any pain during and after training. My heart beat took a few weeks to get back to pre surgery levels. I always wore my polar heart rate monitor for the months and year plus post surgery.
My advice is listen to your body and ease into working out.
I hope this helped and please feel free to ask.
Congrats on your ASD closure!!!!
