Kristi Richard Russ received Matthew Spahn's heart after he was struck by a car and later died.
"So strong, so strong," Spahn says in the video.
"That it is," Russ tells him. "When it’s quiet at night we can hear it without the stethoscope."
Matthew Spahn, Jordan’s son, was 21 years old when he was struck by a vehicle walking home and later died in October 2018, Summer Mossbarger, Jordan Spahn’s fiancee told ABC News. Matthew was an award-winning runner.
