This week we review a recent work from NYU-Langone on the topic of cardiac rehab for the ACHD patient. Does enrollment in a formal cardiac rehabilitation program result in meaningful improvements in exercise tolerance in the ACHD patient? Who can benefit from this? How does the impact of this form of therapy compare with more traditional medical interventions? We speak with the senior author of this week's work, Associate Professor of Medicine at NYU, Dr. Dan Halpern. DOI: 10.1161/JAHA.121.023896
