Has anyone here had open and/or closed heart surgery in the past, and had a safe and smooth vaginal delivery? My cardiologist has always said he didn't see it being an issue for me (I had open and closed heart surgery by the time I was 18 mths old), but just wondered if others actually had some experience with it? My last preg was c section, and this time, as baby is not breech so far, doc is looking at the option for vaginal delivery.
