Hybridizing the hybrid: a "serendipitous bridge" to heart transplantation in a child with hypoplastic left heart syndrome.

We report a unique experience with stage 1 palliation of hypoplastic left heart syndrome (HLHS) using the hybrid approach. The tortuous anatomy of the ductus arteriosus precluded stenting. Persistent ductal patency and ability to support the systemic circulation adequately after prolonged prostaglandin E1 (PGE1) infusion and its subsequent discontinuation presented us with a novel approach to hybrid palliation of hypoplastic left heart syndrome. Our experience offers a tempting approach, but it should not be considered a standard alternative management option to stage I hybrid palliation based on a single case report.

Giant Left Atrial Appendage Aneurysm in an Infant.

Our division wishes to share interesting case images of a giant aneurysm of the left atrial appendage in an infant. He was asymptomatic and was diagnosed incidentally. The aneurysm was excised uneventfully. Left atrial appendage aneurysms are commonly reported in adults, but they are quite rare in the infant population.
