The long-term fate of the right ventricle (RV) for patients with hypoplastic left heart syndrome (HLHS) remains unknown. Physicians have focused on preserving RV function through improvements in operative management, early volume unloading procedures, and afterload reduction. However, there is little understanding of the baseline characteristics of the single RV before any postnatal intervention. The article by Szwast and colleagues [1] analyzes the inherent capabilities of the fetal RV in HLHS compared with age-matched normal fetal hearts before the physiologic load of postnatal life. They found that the RV in a fetus with HLHS has a 20% decrease in cardiac output despite preserved systolic function. The authors demonstrated increased RV ejection force and increased myocardial performance indices that suggest . . . [Full Text of this Article]
