Dennis Hengge, who will be 65 in May, runs near his Pembroke Pines home on Sunday, Feb. 12, 2017. Dennis was a longtime marathon runner when he started feeling shortness of breath and noticed his heart was sustaining a fast rate even after he’d stopped running. He learned he had superventricular tachycardia, an extremely rapid heart rhythm that renders the heart unable to pump blood and can lead to cardiac arrest. After getting treated at Memorial Hospital, he has begun to run again.

  • Air Force special-ops trainee Paul Casas, on being diagnosed with Moyamoya disease, a rare brain disease.

    Paul Casas, a 28-year-old Special Ops Air Force trainee, first became aware of his symptoms when his left arm would go numb and his memory began to slip. He was diagnosed wtih Moyamoya disease, a rare condition that causes blood flow to the brain to be restricted. A University of Miami neurosurgeon, Jacques Morcos, M.D., operated on him on May 24 at Jackson Memorial, performing a double-barrel bypass that would essentially give him a new artery to supply blood flow to the right side of his brain. Four days after the operation, Casas was discharged from the hospital, cured. His symptoms immediately disappeared, with his memory immediately coming back. Casas shared his experience at a new conference on Tuesday, June 6, 2017.
