DALLAS - Kyla Davis had just given birth to her third child when she was hit with a rare and life-threatening heart problem. Surgeons rushed the 40-year-old woman into open heart surgery, where they implanted a battery-operated pump to keep her alive.

"She was going to imminently pass if we hadn't intervened," said Dr. Amarinder S. Bindra, a cardiologist at Baylor Scott & White Health.

The pump, called a left ventricular assist device, or LVAD, is daunting at first, but enter Davis' family. Her husband, Ryan, changes her dressing and found a belt that keeps her more mobile, and her three kids make sure her batteries are freshly charged every night.

"The controller, like, has a pump that goes into the heart that shoots out blood. Well, that's crazy. I don't know how they did it," shared her son, Reece.

"They've seen that the doctors have done an amazing job of helping save Mommy," Davis said. "They know that Mommy's a miracle. They know that it's a blessing that I'm here with them."

"She's probably the best patient we have with the LVAD," Bindra said. She's taking care of her kids. She's back to her job. This is just the best possible outcome that we could hope."

From watching her daughter's first dance recital to cherishing every day with her entire family, Davis knows none of this could happen without a little help from her mechanical 'friend.'

About the only thing Davis can't do is swim or take a bath. She can take showers, as long as she puts her heart assist device in a waterproof nylon bag.
