Three-dimensional (3D) printing is an advanced technology for accurately understanding anatomy and supporting the successful surgical management of complex congenital heart disease (CHD). We aimed to evaluate whether our super-flexible 3D heart models could facilitate preoperative decision-making and surgical simulation for complex CHD. The super-flexible heart models were fabricated by stereolithography 3D printing of the internal and external contours of the heart from cardiac computed tomography (CT) data, followed by vacuum casting with a polyurethane material similar in elasticity to a child's heart.

Article Synopsis
- The study reviews a 20-year experience with extracardiac total cavopulmonary connection (eTCPC) procedures, focusing on 18-mm and 16-mm conduits used in 256 patients, evaluating their impact on mortality and complications.
- The findings revealed that the 16-mm conduit was more commonly used for patients with a right ventricle as the main chamber and showed no significant difference in the need for resurgery but pointed out differing rates of late complications and overall outcomes.
- Ultimately, the research concluded that while the mid-term results for eTCPC were positive, preoperative inferior vena cava pressure was a notable risk factor for complications, rather than the size of the conduit itself.
Background: It is well known that congenital heart disease, especially a ventricular septal defect, is associated with a high risk of infective endocarditis. There are few reports of infective endocarditis with vegetations extending from the right ventricle into the pulmonary artery, resulting in pulmonary artery embolism. It is also well known that atopic dermatitis can be associated with systemic infections such as infective carditis.

Objectives: In children, it is difficult to control mitral valve (MV) or tricuspid valve (TV) regurgitation with conventional procedures alone because complex factors hamper easy improvement of valve coaptation. We investigated interannular bridging in children with MV/TV regurgitation.
Methods: The subjects were 9 patients who underwent interannular bridging to control TV or MV regurgitation between January 2014 and December 2021.
