OPELOUSAS- Cardiovascular Institute of the South (CIS) cardiologist Dr. Siby Ayalloore was the first to implant the Micra pacemaker at Opelousas General Health System (OGHS).

Manufactured by Medtronic, the Micra is the world's smallest pacemaker, measuring about 93 percent smaller than conventional pacemakers.  It is implanted directly into the patient's heart during an interventional procedure—without the need for lead wires. Therefore, the risk of lead breakage, dislodgment or infection is eliminated.  

“Who would have thought that we could hold a computer in our hands, let alone a pacemaker,” said Dr. Siby Ayalloore. “Leadless pacing was a dream in the past, but it is here now—and it will be the future.”


He added, “The procedure is shorter and has a faster recovery time. Pocket infections and high-risk lead extractions are no longer an issue.  This is the gold standard for a single chamber pacemaker.”
