Why it matters

Risk stratification in HLHS is critical for counseling and management. This study identifies a high-risk subgroup—MS/AA with VCCs—that may warrant closer surveillance and tailored decision-making. Prenatal detection of VCCs adds prognostic value, potentially influencing delivery planning and early postnatal care.
