We present the case of a child with borderline hypoplastic left heart complex who initially received Norwood and Glenn operations without atrial septectomy and was later converted to a biventricular circulation after progressive growth of the left ventricle as assessed by serial echocardiography and cardiac magnetic resonance imaging.

Surgical outcome of the borderline hypoplastic left ventricle: impact of the left ventricle rehabilitation strategy.
Cardiol Young
October 2024
Department of Congenital and Pediatric Heart Surgery, German Heart Center Munich, Technische Universität München, Munich, Germany.
Objective: This study aims to assess the surgical outcome of borderline hypoplastic left ventricle before and after the induction of the left ventricle rehabilitation strategy.
Methods: A retrospective review investigated patients with borderline hypoplastic left ventricle who underwent surgical intervention between 2012 and 2022. The patient cohort was stratified into two groups based on the initiation of left ventricle rehabilitation: an early-era group (E group, 2012-2017) and a late-era group (L group, 2018-2022).
Reverse double switch operation for the borderline left ventricle.

Article Synopsis
- - This study examines the effectiveness of the reverse double switch operation (R-DSO) and ventricular switch for treating children with D-looped borderline left hearts, using the right ventricle for systemic circulation.
- - Researchers analyzed outcomes of 28 patients who underwent these procedures between 2015 and 2023, focusing on right ventricular function, tricuspid regurgitation, and other complications; notably, there were no deaths or heart transplants after the operations.
- - The findings suggest that while the R-DSO/ventricular switch may be a viable alternative to traditional treatments, there are concerns about right ventricular function and the need for ongoing patient monitoring, especially in those with pre-existing RV dysfunction. *
A Simplified Staged Left Ventricular Recruitment Strategy to Achieve Biventricular Repair in a Neonate With Hypoplastic Left Heart Variant.
World J Pediatr Congenit Heart Surg
November 2024
Division of Pediatric Cardiology and Cardiac Surgery, The Heart Institute, Le Bonheur Children's Hospital, Memphis, TN, USA.
Hypoplastic left heart complex presents a diverse spectrum of variants. Traditional management has been dichotomous, involving either single ventricle palliation or high-risk biventricular repair. Surgical approaches to achieve biventricular repair in children with borderline left ventricle are continually evolving.

Objectives: In patients with borderline left hearts or a severe left ventricular outflow tract obstruction, hybrid palliation can be used to stabilize the patient and postpone biventricular repair (BVR). In this study, we analysed growth of left-sided structures and outcomes of these patients.
Methods: We conducted a retrospective cohort study including patients who received hybrid palliation between January 2010 and September 2023.
