Heart Hospital of Austin first to test Fire1 heart failure monitor

Donna Whitworth demonstrates how she uses her Fire1 device while at home Friday, Aug. 18, 2023. Whitworth is one of three people in the United States, who have had a Fire1 device implanted into the vein below their heart to measure the pressure of the right side of her heart.

Every morning, Donna Whitworth turns on two device monitors for her heart.

For the first device, she puts on a belt, which is hooked up to a laptop. When the belt is in the proper position, the monitor tells her to take a deep breath and then release it and then take another deep breath.

Then for a minute, she remains still resting on her bed and breathes normally as the belt connects to the tiny Fire1 device inside her inferior vena cava, the large vein that brings blood into the right atrium of the heart.

The Fire1 measures the area of the large vein and transmits that data through the belt to the laptop and to her doctors. That measurement gives information about her heart failure on the right side of her heart.
