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.

在先天性心脏手术中,外科医生必须经常考虑姑息治疗或矫正手术如何受到儿童躯体生长的影响。在儿童瓣膜手术中,现有的瓣膜修复技术缺乏适应生长的假体。阀门更换方案的大小是固定的,不能随着孩子的成长而成长,因此使儿童反复进行阀门再操作。当创建系统到肺动脉分流,替换肺动脉分支或导管,创建心外Fontan通路或肺动脉绑扎时,植入物的大小必须考虑到儿童当前的大小和他或她的预期生长。各种适应增长的技术已经被开发出来,以填补这一未满足的需求。一些设备已经进入临床领域,而一些处于临床前开发阶段。本综述的目的是描述生长装置技术的临床需求,然后回顾先天性心脏手术中已建立和正在发展的生长调节技术。

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.
