GRAND FORKS — Her pregnancy was progressing well when Cassie Marka headed to the clinic for a 20-week ultrasound procedure in the spring of 2013. She and her husband, William, were excited about the pending birth of their first child. "We went in to learn just the gender," Cassie Marka said. But they learned much more. "They said something was wrong with her heart but we'll wait and take a closer look later," she said. The weeks between hearing something was wrong and learning exactly what was wrong were "pretty awful."
