The aim of this study was to characterize the cardiovascular and musculoskeletal systems of elite volleyball players, including aortic dimensions. Previous studies have shown that the upper limit of normal aortic sinus diameter for male and female athletes is 4 and 3.4 cm, respectively.
Cross-sectional analysis.
United States Olympic Volleyball Training Facility and Rady Children's Hospital San Diego.
Seventy (37 male) members of the US national volleyball team.
Athletes underwent evaluation that included medical and family histories, targeted physical examinations specifically focusing on abnormalities present in Marfan syndrome (MFS), and transthoracic echocardiograms. Cardiac chamber and great artery size, valve function, and coronary artery origins were assessed.
Three male athletes (8%) had an aortic sinus diameter ≥4 cm, one of whom also had an ascending aorta >4 cm. Two female athletes (6%) had aortic sinus diameter ≥3.4 cm, and another had an ascending aorta of 3.4 cm. There were no other intracardiac or arterial abnormalities. Individual musculoskeletal characteristics of MFS were common among the athletes but not more frequent or numerous in those with aortic dilation.
The prevalence of aortic root dilation in this population of athletes was higher than what has previously been reported in other similar populations. Further study is needed to determine whether these represent pathological changes or normal variations in tall athletes.
This study adds to the existing knowledge base of athlete's heart, with specific attention to aortic dimensions in elite volleyball players. The data are relevant to similar athletes' medical care and to preparticipation cardiac screening in general.
本研究旨在描述精英排球运动员的心血管及肌肉骨骼系统特征，包括主动脉尺寸。既往研究表明，男性和女性运动员正常主动脉窦直径的上限分别为4厘米和3.4厘米。
横断面分析。
美国奥林匹克排球训练设施及圣地亚哥瑞迪儿童医院。
美国国家排球队的70名队员（37名男性）。
运动员接受了包括病史和家族史、专门针对马凡综合征（MFS）异常情况的针对性体格检查以及经胸超声心动图检查。评估了心腔和大动脉尺寸、瓣膜功能以及冠状动脉起源。
3名男性运动员（8%）的主动脉窦直径≥4厘米，其中1人升主动脉也>4厘米。2名女性运动员（6%）的主动脉窦直径≥3.4厘米，另1名女性运动员升主动脉直径为3.4厘米。未发现其他心内或动脉异常。MFS个体的肌肉骨骼特征在运动员中很常见，但在主动脉扩张的运动员中并不更频繁或更多见。
该运动员群体中主动脉根部扩张的患病率高于此前在其他类似人群中的报道。需要进一步研究以确定这些情况是高大运动员的病理变化还是正常变异。
本研究增加了关于运动员心脏的现有知识库，特别关注精英排球运动员的主动脉尺寸。这些数据与类似运动员的医疗护理以及一般的赛前心脏筛查相关。
