 I'm Joe Forbus, I'm Professor of Surgery at the University of Maryland School of Medicine and Surgical Director of the Children's Heart Program at the University of Maryland Medical Center. I'm a congenital heart surgeon by training and trade and that means that I take care of patients who were born with heart defects. And interestingly, congenital heart disease is the most common birth defect that requires surgery or some sort of intervention, frequently they're in the catheterization laboratory now, in the first year of life. So these defects are extremely complicated and yet there usually is a pathway to get things fixed. I sometimes describe myself as a general contractor of the heart and cardiovascular system to parents and patients. I fix pipes that are too small, I rearrange pipes that come off the wrong chamber, I patch walls, I implant pacemakers to help with the electrical system so it is not dissimilar from being a general contractor as far as solving structural problems. The best part about what I do is being able to help families and patients during what is an extremely important and stressful time of their life. The gratification you get can be quite immediate and then it can also be quite delayed and so patients are now entering college and sending me thank you notes and so that's a very, very meaningful thing to have had that kind of impact on a person. I know of one patient, he's in college now, I operated on him when he was a newborn and he's a musician and he put out an album and I made the liner notes where he thanked me on his album, which I thought was pretty cool.
