I held my wife Veronica's hand as the technician applied cool gel to her chest. At first, the ultrasound images were the fuzzy black-and-whites I remembered from before our daughters Rebecca and Hannah were born. After a few touches to the LCD screen, a breathtaking three-dimensional movie began to run. It featured Veronica's heart, its thick walls beating yellow against a black background.
The technician maneuvered a trackball to reveal the various parts undulating in unison. Colored regions displayed blood velocity and turbulence through the different chambers. Suspended in virtual space, Veronica's heart looked every millimeter the impregnable pump I had always assumed it was.
