Novel Approaches to the Failing Congenital Heart.

PURPOSE OF REVIEW: Heart failure is the leading cause of morbidity and mortality in adults with congenital heart disease and is characterized by a variety of underlying mechanisms. Here, we aim to elaborate on the medical and technological advancements in the management of heart failure in adult patients with congenital heart disease and highlight the use of imaging modalities to guide therapy. RECENT FINDINGS: There have been several advances over the past decade with angiotensin receptor neprilysin and sodium-glucose cotransporter-2 inhibitors, atrioventricular valve clips, transcatheter pulmonary valves, catheter ablation, and cardiac resynchronization therapy, as well as the introduction of lymphatic interventions. Expanded use of echocardiography, cardiac magnetic resonance imaging, and cardiac computed tomography has guided many of these therapies. Significant innovations in the management of heart failure in adults with congenital heart disease have evolved with advancements in imaging modalities playing a critical role in guiding treatment therapies.
