Key result
High-risk anatomic features in hypoplastic left heart syndrome, such as restrictive atrial septum and small ascending aorta, necessitate alternative treatment strategies to traditional staged palliation.
Why the study?
Despite improved outcomes in hypoplastic left heart syndrome, specific high-risk anatomic features complicate traditional staged palliation and warrant the examination of alternative management strategies.
Identification of high-risk anatomic features in HLHS is crucial for guiding alternative treatment strategies and improving outcomes.
Despite overall improvements in outcomes for patients with hypoplastic left heart syndrome, there remain anatomic features that can place these patients at higher risk throughout their treatment course. These include severe preoperative obstruction to pulmonary venous return, restrictive atrial septum, coronary fistulae, severe tricuspid regurgitation, smaller ascending aorta diameter (especially if <2 mm), and poor ventricular function. The risk of traditional staged palliation has led to the development of alternative strategies for such patients. To further improve the outcomes, we must continue to diligently examine and study anatomic details in HLHS patients.

Geoffrion et al. (2022) conducted a review in Hypoplastic left heart syndrome. High-risk anatomic features was evaluated. High-risk anatomic features in hypoplastic left heart syndrome, such as restrictive atrial septum and small ascending aorta, necessitate alternative treatment strategies to traditional staged palliation.
