Sharon Allen was a healthy mother of five when she suddenly collapsed. Every second mattered as she was flown to MedStar Heart & Vascular Institute at MedStar Washington Hospital Center. Despite the rare condition, our team of specialists diagnosed her from a distance, planning Sharon's surgery while she was still in the air. Following extensive surgery, Sharon was placed on ECMO, an advanced technology that gave her heart time to heal -- and allowed her to return to her loving family. Every day, our teams come together like clockwork, putting patients first, above all else.
