Welcome to Pediatrix Cardiology Associates and Tampa Bay Adult Congenital Heart Center. At our Tampa Medical Arts location, our offices are located on the 2nd and 3rd floors. Pediatric Cardiology Associates opened its doors in 1977 as the first pediatric cardiology program on the west coast of Florida. Since then, we have recruited nationally and internationally respected specialists in all areas of pediatric cardiology, including arrhythmia, fetal, therapeutic interventions and transplant cardiology. We also helped to establish the Tampa Bay Congenital Heart Center to treat the growing population of adults with congenital heart conditions.
