CardioNerds (Daniel Ambinder) and ACHD series co-chair Dr. Dan Clark discuss advanced heart failure therapies including mechanical circulatory support (MCS) and heart transplantation (HT) in patients with adult congenital heart disease (ACHD) with Dr. Rafael Alonso-Gonzalez, cardiologist and director of Adult Congenital Heart Disease program at the University of Toronto and ACHD fellow Dr. Andy Pistner (University of Washington). They cover epidemiology of heart failure in ACHD, outcomes after HT, unique challenges of HT in this population, impact of allocation policies on access to transplantation, and regionalization of advanced heart failure care. They also discuss a practical approach to advanced heart failure therapy evaluation in ACHD. Audio editing by CardioNerds Academy Intern, student doctor Adriana Mares.
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 Saef, Dr. 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. See more

Pearls - Advanced Heart Failure Therapies (MCS/HT) Among ACHD Patients
Heart failure is a major comorbidity and the leading cause of death in adults with congenital heart disease.Identification of advanced heart failure in ACHD is challenging. ACHD patients do not always self-identify exercise limitations or exertional dyspnea. Cardiopulmonary exercise testing is a useful tool in evaluating these patients.Patients with ACHD awaiting heart transplantation are less likely than non-ACHD patients to receive a heart transplant, and ACHD patients have an increased risk of death or delisting while awaiting heart transplantation.Evaluation of transplant candidacy and potential need for multi-organ transplantation in complex congenital heart disease (i.e., Fontan palliation) requires a multidisciplinary approach.Regionalization of care improves outcomes for ACHD patients with advanced heart failure. High volume transplant centers have better early survival for ACHD patients after heart transplant, and the highest volume ACHD transplant centers in each UNOS region have better early survival.
Show notes - Advanced Heart Failure Therapies (MCS/HT) Among ACHD Patients
1. How many ACHD patients have heart failure?
Patients with ACHD are a large and heterogeneous group. The signs and symptoms of heart failure vary widely depending on the underlying congenital heart disease. Patients with D-transposition of the great arteries repaired with an arterial switch operation have low rates of heart failure (~3%)1 compared to those patients Fontan palliation for single ventricle physiology (40%)2. Heart failure is the leading cause of death in patients with ACHD3,4.
2. How many patients with ACHD end up receiving a heart transplant or mechanical circulatory support?
Heart transplantation for congenital heart disease in adults has been increasing in frequency since the late 1980s. Between 2010 and 2012, this accounted for 4% of all adult heart transplants in the United States5. This represents a small fraction compared to the number of adults who die due to complications of heart failure ...
