A few weeks later, he says he experienced a similar pain in his arm. That time, he went to UCHealth University of Colorado Hospital at the Anschutz Medical Campus in Aurora. Doctors removed what was thought to be another clot. “We questioned as to why I would have a blood clot anywhere at my age and with my health, especially in an artery. It just didn’t make any sense to us,” Brian said. Upon further testing, Dr. Muhammad Aftab, a cardiac surgeon at the Anschutz, discovered the problem in Brian’s heart. “There was just so much extensive vegetation which was covering all the valves,” Dr. Aftab said.
