I have mentioned the Cardiosmart website as a resource a few times in individual posts. This is a terrific website supported by the American College of Cardiology, the major professional society for cardiac caregivers in the US (and with plenty of international members as well). There are some good pages dealing with common cardiac conditions and procedures. There are some links to helping you find a cardiology specialist in your area if needed. I'll continue to refer to specific pages when I think that someone might benefit from some of the materials but for now, take a look and see if there are some things that you find helpful.
