World’s Smallest Heart Pump Comes to St. Joseph’s Mercy

1 min read

The St. Joseph’s Mercy Heart & Vascular Center in Hot Springs said Friday that it is now using the "World’s Smallest Heart Pump" in some cardiac procedures.

The device is called the Impella 2.5, and Mercy said it is the first hospital in the region to use it.

"It basically does the pumping work for the heart," Mercy Interventional Cardiologist Dr. Srinivas Vengala said in the news release. "It pumps the blood out of the heart and into the body.”

The minimally-invasive, catheter-based procedure uses "revolutionary new technology" which provides partial circulatory support by a small pump inserted into the heart without the need for any incisions, the news release said.

"It supports the heart after the heart attack to recover faster and better," Vengala said. "This pump allows our doctors to perform complex interventional procedures in patients who were not good candidates for surgery."
