Texas Cardiac Arrhythmia Institute at St. David's Medical Center first in U.S. to use FDA-approved novel wireless system to treat cardiac arrhythmias

The system is the first-ever to stimulate the heart muscle electrically via a small, leadless device—about the size of a grain of rice—that is implanted inside tissue of the left ventricle, the heart's primary pumping chamber. The device converts ultrasound energy into electrical pulses, restoring the heart's normal rhythm and pumping efficiency.

The system is the first-ever to stimulate the heart muscle electrically via a small, leadless device—about the size of a grain of rice—that is implanted inside tissue of the left ventricle, the heart's primary pumping chamber. The device converts ultrasound energy into electrical pulses, restoring the heart's normal rhythm and pumping efficiency.

Traditional cardiac resynchronization therapies involve leads—thin and soft insulated wires about the size of a spaghetti noodle. This left ventricular endocardial pacing device provides a direct approach, which enables more flexible placement and expands access to those who were previously considered untreatable.

TCAI is a state-of-the-art Electrophysiology Center that includes six labs equipped with advanced technology where a group of esteemed cardiac electrophysiologists—led by Dr. Natale, a world-renowned expert in the field—perform a high volume of the most complex electrophysiology procedures.
