Dr. Anthony C. McCanta, Pediatric Cardiology

  • Anthony C McCanta MD
  • Appointments:
  • Office: 714-509-3939
  • Specialties: Cardiology, Cardiac Electrophysiology
  • Board Certified: Pediatrics, Pediatric Cardiology

Dr. McCanta is a board certified pediatric cardiologist specializing in pediatric electrophysiology. He is certified to care for infants, children and young adults with heart rhythm problems. Dr. McCanta regularly treats conditions such as:

  • Supraventricular tachycardia
  • Wolff-Parkinson-White syndrome
  • Premature atrial or ventricular beats
  • Ventricular tachycardia
  • Life-threatening diseases such as long QT syndrome and catecholaminergic polymorphic ventricular tachycardia (CPVT), or any other genetic conditions which predispose patients to dangerous rhythms.

To treat heart rhythm disorders, Dr. McCanta has expertise in a variety of therapies, including anti-arrhythmic medications, cardiac catheterization with ablation using radiofrequency or cryoenergy, and implanted pacemakers and defibrillators.

In addition to infants and children, Dr. McCanta also specializes in caring for adults whose congenital heart disease was palliated as an infant or child, many of whom develop heart rhythm disorders as a result of their surgeries. He evaluates patients with symptoms suggesting heart rhythm issues including palpitations (the feeling of heart racing), syncope (fainting), chest pain or exercise issues. He has experience caring for young people with abnormalities of the autonomic nervous system such as postural orthostatic tachycardia syndrome and vasovagal syncope.

A native of Orange County, Dr. McCanta is an alumnus of Servite High School in Anaheim. He attended the University of Notre Dame and earned his medical degree from Loyola University Chicago Stritch School of Medicine. Dr. McCanta then returned home for his pediatric residency at CHOC, where he was named chief resident of pediatrics. It was at CHOC where Dr. McCanta was encouraged to pursue a career in pediatric cardiology.

Dr. McCanta undertook a pediatric cardiology fellowship at the University of Colorado Denver/Children’s Hospital Colorado, followed by a pediatric electrophysiology fellowship at Duke University in Durham, N.C. The training at Duke also included the care of adults with congenital heart disease. After his fellowships, Dr. McCanta served as faculty of the University of Colorado Denver/Children’s Hospital Colorado for more than three years before returning to Orange County.

Dr. McCanta’s academic career includes authorship of several peer-reviewed journal manuscripts and numerous invited lectures at regional, national and international meetings. His research interests include novel imaging techniques for the catheter ablation of arrhythmias, new technologies for implanted pacemakers and defibrillators such as the subcutaneous implantable cardioverter-defibrillator (S-ICD), and population-based strategies to prevent sudden cardiac death in adolescents. He is also the course director of the Pediatric and Adult Congenital Electrophysiology Society’s international conference, Advancing the Field: A Forum on Practice Innovation, Scientific Achievement, and Career Development, which focuses on improving the care of pediatric and congenital heart disease patients.

Dr. McCanta is married and is the father of two young boys. He enjoys longboard surfing, mountain biking and snow skiing, and he plays multiple instruments.
