Hypoplastic Left Heart Syndrome Overview

Hypoplastic left heart syndrome is a severe congenital heart defect involving underdevelopment of the left ventricle and other left-sided cardiac structures, leaving the right ventricle responsible for systemic circulation after birth. Without intervention, the condition is life-threatening. Current management relies primarily on neonatal stabilization followed by staged Norwood, Glenn, and Fontan procedures, with transplantation reserved for selected patients who develop severe cardiac failure. Although staged palliation does not restore normal biventricular physiology, contemporary outcomes have improved substantially, while long-term single-ventricle complications remain a major unmet need. This has driven investigation of regenerative approaches intended to preserve or improve right-ventricular function and, in selected anatomy, support ventricular recruitment. Lomecel-B, an allogeneic mesenchymal cell therapy, has advanced to Phase IIb evaluation, although efficacy remains unproven. Other cardiac progenitor-cell studies have demonstrated safety and feasibility but mixed efficacy signals, highlighting the challenges of regenerative therapy in this population. Fetal interventions such as balloon aortic valvuloplasty are also being investigated in selected fetuses with evolving HLHS, while pediatric ventricular-assist technologies offer potential support for severe heart failure but remain difficult to apply in single-ventricle physiology. For stakeholders, HLHS represents an important frontier where the long-term opportunity is to preserve ventricular function, reduce Fontan-related morbidity, and ultimately expand options beyond lifelong single-ventricle physiology.
