The new technology is the smallest in the world, defibrillation probe administered by catheter
AUSTIN, TX, February 2, 2026 /PRNewswire/ — Electrophysiologists at the Texas Cardiac Arrhythmia Institute (TCAI) at St. David’s Medical Center recently became the first in the nation to implant a new FDA-approved defibrillation lead, a specialized, insulated wire that connects to an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy device (CRT-D) in the heart and corrects an abnormal rhythm. The defibrillation lead is the world’s smallest catheter-delivered defibrillation lead, which allows for precise delivery and placement into the right ventricle.
The first procedure was performed by Robert Canby, MD, and Amin Al-Ahmad, MD, clinical cardiac electrophysiologists at TCAI, on January 7. Dr. Canby was also involved in the trial that led to FDA approval.
“When treating patients, safety and effectiveness are paramount, and this new technology allows us to achieve both with greater precision,” said Andrea Natale, MD, FHRS, FACC, FESC, cardiac electrophysiologist and executive medical director of TCAI. “This milestone is a testament to the Texas Cardiac Arrhythmia Institute’s continued pursuit of innovation that will improve outcomes and access to lifesaving care.”
A lead detects the heart’s rhythm and transmits signals to the implanted device, which then delivers treatment to correct or interrupt abnormally fast rhythms, called arrhythmias, which can lead to sudden cardiac arrest. Existing defibrillation leads have a larger diameter, which increases the risk of future complications.
According to the Journal of the American Heart Associationan estimated 12.1 million people in the United States will have atrial fibrillation, the most common arrhythmia, by 2030.
TCAI is a state-of-the-art electrophysiology center that comprises six laboratories equipped with cutting-edge technology where a group of esteemed cardiac electrophysiologists, led by Dr. Natale, a world-renowned expert in the field, performs a large number of the most complex electrophysiology procedures.
