Meet our team


Experienced. Exceptional. Dedicated.

The Texas Cardiac Arrhythmia Institute’s team of physicians consists of some of the world’s most eminent and esteemed electrophysiologists.

Led by Dr. Andrea Natale, TCAI provides patients with singularly superior patient care, while advancing the overall level of cardiac arrhythmia treatment through research and technology.

Globally recognized and respected for their work, TCAI’s physicians travel internationally, leading and participating in conferences, initiating innovative techniques and influencing the future of their field.

EP lab team

Professional. Personable. Experienced.

Procedures at the Texas Cardiac Arrhythmia Institute (TCAI) are performed in a state-of-the-art Electrophysiology Lab (EP Lab) at St. David’s Medical Center, named by Truven among the 100 Top Hospitals in the Nation. The electrophysiology physicians are supported by a dedicated team of nurses, technologists and tertiary staff. These cardiac professionals combine extensive knowledge of electrophysiology procedures with years of experience in the field.

During a procedure, these personnel work hand-in hand at the table side with the physician while focusing on the safety and comfort of the patient. Each staff member is able to decipher the complex pattern of electrical impulses inside the heart—expertise that allows the physician to focus on curing the patient.

With the vast array of advanced systems involved in electrophysiology, a lab can quickly fall behind the curve. The technology in the EP Labs at TCAI represents the most advanced in the world. The nurses and technologists of TCAI are among the most experienced in the world in using these advanced mapping and imaging systems.This enables TCAI to remain on the leading edge in the race to improve every facet of technology involved in electrophysiology, and has led to TCAI being one of the first to utilize almost every new technology over the last several years.

Ultimately, the quality of these professionals sets TCAI apart and allows it to remain a leader in the field of electrophysiology.

Carlos Monreal, RCES

Supervisor of Electrophysiology Labs

Carlos began working in electrophysiology in 2005, and started his career at St. David’s Medical Hospital in the electrophysiology lab in October 2007. He’s worked as a scrub tech, lead tech and now serves as one of two EP lab supervisors. Carlos checks in with patients as many as three times a day to receive feedback and also show them they are valued at St. David’s. He particularly enjoys that working in the EP lab over 12 years means using the newest technology and witnessing pioneer studies with many cases.

Matthew Dare, CEPS

Research and Technology Coordinator, Electrophysiology Services

Matt has more than a decade of electrophysiology experience and a background in biomedical engineering, EMS, and cardiovascular imaging. At Texas Cardiac Arrhythmia Institute, Matt provides in-house technical support, advanced clinical support, and planning for new systems, procedures, training and educational programs. He also manages and operates the International Training Center, which has the capability to transmit live procedures around the world. Matt particularly enjoys working in an environment that is committed to being among the first to implement new technology.

Research team

Learning. Teaching. Leading.

In addition to treating patients with heart rhythm disorders, the Texas Cardiac Arrhythmia Institute is fully dedicated to advancing the standard of care available to patients worldwide through research and training.

Led by Dr. Andrea Natale, TCAI’s research team leads and is involved in many clinical cardiac and sophisticated electrophysiology studies, as well as data analysis and statistical modeling. The Institute’s participation in a wide variety of clinical trials means our patients gain access to emerging advances well before what might otherwise be possible.

At the same time, physicians come from across the country and around the world to the Institute’s Cardiac Training Lab, where they can work with the latest technologies and train in the newest electrophysiology techniques. The lab—the first of its kind in the U.S.—makes it possible for physicians to observe procedures both on site and remotely, interacting with surgeons and researchers in real time, as they deal with complex and challenging arrhythmia cases.

Nurse navigators

Unique. Knowledgeable. Nurturing.

The Texas Cardiac Arrhythmia Institute—through its Center for Arrhythmias & Atrial Fibrillation—offers AFib patients a special service intended to help turn a potentially overwhelming medical process into a smooth return to heart health.

Inspired by the concierge concept, our nurse navigator program connects patients directly with a TCAI nurse who will give them all the information and thoughtful attention they need, from their diagnosis through their recovery. The nurse navigator serves as the patient’s personal guide for this journey.

Before a patient’s first consultation with the doctor and for a full year after their procedure at the hospital, the nurse navigator is the patient’s point-person—always just a quick call away—with essential answers to all of their questions, from driving directions to healing concerns.
