AUSTIN, Texas, July 21, 2025 /PRNewswire/ — Electrophysiologists at the Texas Cardiac Arrhythmia Institute (TCAI) at St. David’s Medical Center recently became the first in the nation to implant an FDA-approved novel leadless system that provides cardiac resynchronization therapy to patients with heart failure. Cardiac resynchronization therapy improves the timing of the heart’s contractions, helping to restore the normal rhythm of the heartbeat. The first procedure was recently performed by Robert Canby, M.D., cardiac electrophysiologist at TCAI.
