Thousands of patients were implanted with heart pumps that the FDA knew could be dangerous


 

“A no-brainer”

When children asked Latoya Johnson Keelen about the cable that came out of her side and connected to a controller on her hip, she told them she was Iron Woman.

For a while, she felt invulnerable with the HVAD on her heart.

Johnson Keelen, who lives in the Atlanta suburbs, learned she needed the device after delivering her fourth child, Isaiah, in early 2018. Doctors diagnosed her with postpartum cardiomyopathy, a rare and mysterious form of heart failure that afflicts mothers during pregnancy or after birth. Black mothers in the South have among the highest rates of the illness. Some mothers quickly regain heart function, some only partially recuperate and others never recover.

Tests showed that Johnson Keelen, then 42, was suddenly in end-stage heart failure.

Her body’s immune response at the time was too strong for her to receive a heart transplant. Doctors gave her two choices: an HVAD or end-of-life hospice care.

“It became a no-brainer,” she said. “I just had a baby. I just gave birth. I’m not ready to plan for a funeral.”

Johnson Keelen, a woman of faith, believed God would heal her, either through a medical advancement or a miracle. She thought the HVAD was the answer.

Living with a life-sustaining medical device was difficult at first for the fiercely independent mother. She had to leave her job as a public health communications specialist, ask her older sons to change her bandages and lean heavily on her new husband, only a year into their marriage.

But, for about three years, she found comfort in the soft humming of the HVAD’s spinning rotor at night. It served as a lullaby for her new baby when he lay on her chest.

She said she was never told about the manufacturing problems the FDA repeatedly found at HeartWare’s facilities or about device recalls, including one sent to patients in December 2020. The notice said the device sometimes wouldn’t restart properly, which had led to two patient deaths at that point. It warned that current patients should always keep at least one power source, a battery or an AC or DC adapter, connected at all times to avoid the need for a restart.

Two months after that notice, Johnson Keelen was getting her kids ready for school when the HVAD’s low-battery alarm blared. She had unplugged the battery to replace it without realizing her wall adapter was disconnected.

Once before, Johnson Keelen had simply plugged the charger back into the outlet and her device restarted. But this time it wouldn’t.

As an emergency alarm sounded, she called the ventricular-assist team assigned to her case, and a specialist directed her to switch out the device controller.

Nothing changed, and panic crept into the voice on the phone.

An ambulance took Johnson Keelen to a hospital where medical staff used several backup controllers to try to start the pump.

Still nothing.

Doctors and nurses tried to keep calm, but Johnson Keelen could see fear and shock on their faces. Without the HVAD, her only options were a transplant or a completely new pump.

Doctors scurried to locate a donor heart and airlifted her for an emergency transplant. But while running tests, the medical team was stunned to find that Johnson Keelen’s miracle had occurred: Her heart was once again pumping blood on its own.

She had a new choice. She could avoid the risks of transplant rejection and open heart surgery during the pandemic by leaving the device on her functioning heart, while cutting the wires, removing the external components and sealing the pump.

She chose to trust her newly functioning heart, and leave the decommissioned HVAD inside her.

Three months later, when Medtronic said it was stopping HeartWare sales and implants, its announcement cited the problem with pumps not restarting among the reasons.
