It's 9:20 AM on a Tuesday morning, and I'm looking at Joseph Siciliano's beating heart. I can get three different views as I stand in the surgical suite on the sixth floor of New York University Medical Center. A monitor on my right shows the rhythmic spikes of an echocardio-gram. A monitor at the left shows a detailed color picture taken by a fiber-optic scope inserted into Joe's chest. And if I crane my neck a bit, I can see the heart itself, through a 4-inch incision that Dr. Stephen B. Colvin, Joe's surgeon, has made between the ribs.
