Cardionerds - A Cardiology Podcast:

Adult Congenital Heart Disease Page

Welcome to the CardioNerds Adult Congenital Heart Disease Series Page! 

With landmark advances in the care of children with congenital heart disease, survival has improved, and more are living into adulthood. There are now more adults living with congenital heart disease than children. This is no longer a pediatric specialty alone. This growing population requires a specialized and personalized approach from multidisciplinary teams. While not every CardioNerd will specialized in ACHD, we will all have the opportunity to touch the lives of adults living with CHD, recognize their unique needs, and refer them to the appropriate centers if and when needed. 

The CardioNerds Adult Congenital Heart Disease (ACHD) series provides a comprehensive curriculum to dive deep into the labyrinthine world of congenital heart disease with the aim of empowering every CardioNerd to help improve the lives of people living with congenital heart disease.

This series is multi-institutional collaborative project made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Josh SaefDr. Agnes Koczo, and Dr. Dan Clark.

The CardioNerds Adult Congenital Heart Disease Series is developed in collaboration with the Adult Congenital Heart Association, The CHiP Network, and Heart University. 


CardioNerds (Amit Goyal and Daniel Ambinder), ACHD series co-chair Dr. Agnes Koczo (UPMC), and ACHD FIT lead Dr. Katia Bravo (UCLA) join ACHD expert Dr. Carole Warnes (Professor of Medicine and founder of the Adult Congenital Heart Disease Clinic at Mayo Clinic), to discuss adult congenial heart disease and pregnancy. They cover preconception counseling in women with congenital heart disease, appropriate risk stratification to estimate maternal and neonatal morbidity using existing tools and an individualized care approach and preparation for a multidisciplinary delivery plan.
