The Melody Valve in Small Children Undergoing First Mitral Valve Replacement: Better Than Mechanical?

Background: In small children with left atrioventricular valve dysfunction, valve repair is preferred but some will require valve replacement. No prosthetic valve has growth potential, bioprostheses have poor durability, and mechanical prostheses have high rates of thromboembolic and hemorrhagic complications. We reviewed our experience with a modified bovine jugular vein valve designed for use in the right ventricular outflow tract (Melody valve, Medtronic) and compared this with contemporary mechanical valve replacement.

Left Atrial Appendage Aneurysm Characterized by Multimodal Imaging.

We present a four-year-old female with an incidental finding of a congenital left atrial appendage aneurysm who underwent surgical resection with excellent results. This case highlights the importance of multimodal imaging in the diagnosis and characterization of this rare condition.

Heart Transplant in Patient With Isolated Left Superior Vena Cava by Atrial Appendage Rotation.

Orthotopic heart transplantation in patients with an isolated persistent left superior vena cava is extremely rare, and the anastomotic connection between a right-sided donor superior vena cava and left-sided recipient superior vena cava can be challenging to perform. We present a novel technique used in an infant female, using the left atrial appendage to extend the superior vena cava anastomosis.
