Background Pectus excavatum, the most common chest wall deformity in children, accounts for nearly 90% of congenital malformations of chest wall. Initially, both parents and doctors paid more attention to the influence of this deformity on patient appearance and psychology. Following deeper studies of pectus excavatum, researchers found that it also affected cardiac functions. The purpose of this review aims to present recent research progress in the effects of pectus excavatum on cardiac functions. Data sources Based on aspects of CT, ultrasound cardiography (UCG) and MRI, all the recent literatures on the influence of pectus excavatum on cardiac function were searched and reviewed. Results Moderate and severe pectus excavatum did have a negative effect on cardiac function. Cardiac rotation angle, cardiac compression index, right atrial and tricuspid annulus size, septal motion and myocardial strain are relatively effective indexes to evaluate cardiac function. Conclusions Pectus excavatum did have a negative effect on cardiac function; so surgeons should actively diagnose and treat such patients in clinical work. However, further research is needed on to explore the measures and indicators that can reflect the changes of cardiac function in patients objectively, accurately, effectively and timely.

漏斗胸对心功能影响的研究进展

研究背景漏斗胸是儿童最常见的胸壁畸形，占先天性胸壁畸形的近90%。最初，家长和医生都比较关注这种畸形对患者外貌和心理的影响。在对漏斗胸进行更深入的研究后，研究人员发现它也会影响心脏功能。本综述旨在介绍漏斗胸对心脏功能影响的最新研究进展。资料来源 从CT、超声心动图（UCG）和MRI等方面，对近期有关漏斗胸对心功能影响的文献进行检索和综述。结果 中度和重度漏斗胸确实对心脏功能有负面影响。心脏旋转角度、心脏压缩指数、右心房和三尖瓣环大小、室间隔运动和心肌应变是评价心功能的较有效指标。结论 漏斗胸确实对心功能有负面影响；因此外科医生在临床工作中应积极诊治此类患者。但有待进一步研究探索能够客观、准确、有效、及时地反映患者心功能变化的措施和指标。
