Midterm Follow-Up After Biventricular Repair of the Hypoplastic Left Heart Complex

Neonatal biventricular repair is successful and safe in HLHC patients, even with preoperative mitral and aortic valve annulus Z-scores of −4.5 and −5.5, respectively. Residual or restenosis required reintervention in 37% of our HLHC population, but was not significantly correlated with the magnitude of the preoperative Z-scores. Within the first 6 months of follow-up, the Z-scores almost normalized.
