    Congenital Heart Disease, Vol.20, No.6, pp. 659-671, 2025, DOI:10.32604/chd.2025.073864 - 10 February 2026
    (This article belongs to the Special Issue: Novel Insights into Congenital Heart Disease: Pathophysiology, Biomarkers, and Future Directions)
    Abstract Background: An increasing number of patients with Fontan circulation are reaching adulthood; however, long-term outcomes remain limited by Fontan failure, which is characterized by elevated central venous pressure (CVP) and reduced cardiac output. Red blood cell distribution width (RDW), a readily available hematological parameter, is a known prognostic marker of heart failure. However, its relationship with invasive hemodynamics in adolescent and adult Fontan patients has not been fully examined. Objectives: To clarify the association between RDW and invasive hemodynamic indices in adolescent and adult Fontan patients and assess the utility of RDW as a noninvasive circulatory… More >

    Interventional Treatment of Abnormal Veins Following Surgical Repair of Complex Congenital Heart Disease

    Zhengwei Li1,#, Xin Li2,#, Dong Luo1, Meijun Liu1, Luxi Guan1, Haibo Hu1,*
    Congenital Heart Disease, Vol.20, No.6, pp. 673-682, 2025, DOI:10.32604/chd.2026.069714 - 10 February 2026
    Abstract Background: During the surgical repair of complex congenital heart disease (CCHD), a subset of patients is unable to tolerate abrupt postoperative hemodynamic shifts, which can lead to significant complications. To mitigate this risk, certain abnormal venous channels are deliberately left open at the conclusion of surgery to provide a decompressive route, thereby reducing the likelihood of pulmonary hypertensive crises. Nevertheless, the continued patency of these vessels may induce chronic hemodynamic disturbances, often requiring subsequent treatment. This study was designed to assess the safety and efficacy of transcatheter intervention for such persistent anomalous systemic veins in CCHD… More >

    Congenital Heart Disease, Vol.20, No.6, pp. 729-735, 2025, DOI:10.32604/chd.2025.071937 - 10 February 2026
    (This article belongs to the Special Issue: Novel Methods and Techniques for the Management of Congenital Heart Disease)
    Abstract Obstructed infradiaphragmatic total anomalous pulmonary venous return (TAPVR) in premature infants presents significant management challenges due to the high surgical risk in low-birth-weight, preterm neonates. We present strategies for managing this condition in a 10-day old 1.3 kg ex-32-week premature infant including late umbilical venous access, use of wire-snare rail for stable stent deployment, and monitoring for progressive multi-level obstruction. Long-term follow-up demonstrated spontaneous stent fracture and occlusion. This approach successfully bridged to definitive repair with excellent outcomes. More >
