Abstract
In congenital heart surgery, the surgeon must constantly consider how a palliative or corrective procedure could be impacted by the child's somatic growth. Within pediatric valve surgery, existing valve repair techniques lack growth-accommodating prostheses. Valve replacement options are fixed in size and unable to grow with the child, thus subjecting children to repeated valve reoperations. When creating a systemic-to-pulmonary artery shunt, replacing a branch pulmonary artery or conduit, creating an extracardiac Fontan pathway, or banding the pulmonary artery, the implant size must factor in both the child's current size and his or her anticipated growth. A variety of growth-accommodating technologies have been developed to fill this unmet need. Some devices have reached the clinical arena, while several are in preclinical development. The purpose of this review is to characterize the clinical need for growing device technology, and then review established and developing technologies for growth accommodation in congenital heart surgery.
期刊介绍:
The Pediatric Cardiac Surgery Annual is a companion to Seminars in Thoracic and Cardiovascular Surgery . Together with the Seminars, the Annual provides complete coverage of the specialty by focusing on important developments in pediatric cardiac surgery. Each annual volume has an expert guest editor who invites prominent surgeons to review the areas of greatest change in pediatric cardiac surgery during the year. Topics include 1) Complete Atrioventricular Canal; 2) New Concepts of Cardiac Anatomy and Function -- The Helical Heart; 3) Valve Reconstruction (Replacement) in Congenital Heart Disease; 4) Evolving Developments in Congenital Heart Surgery.
