John DeBusk

By the time he arrived in the parking lot of the hospital, he was in cardiac arrest.

John DeBusk, 61, from Knoxville, Tennessee, is a retired engineer who had installed imaging equipment in catheterization labs for nearly 35 years. On April 15, 2019, John was working in his yard when he felt something was wrong and drove himself to Parkwest Medical Center to seek treatment. By the time he arrived in the parking lot of the hospital, he was in cardiac arrest.

Once in the catheterization lab, Dr. Ayaz Rahman immediately identified that John was in cardiogenic shock and placed the Impella CP® heart pump to support John’s heart before placing stents. Following the hospital’s protocol, the medical team evaluated John’s hemodynamics with a pulmonary artery catheter and identified that he also needed right-heart support (BiPella). Dr. Rahman then implanted the Impella RP®. After biventricular support, John showed significant improvement and his heart was recovering. He was subsequently weaned from both the Impella CP and the Impella RP.

12 days later, John was discharged home with his native heart and normal heart function. Today, he is enjoying retirement tending to more than 40 acres of land and has returned to an active lifestyle playing tennis.
