Athlete preparticipation screening focuses on preventing sudden cardiac death (SCD) by detecting diseases such as arrhythmogenic ventricular cardiomyopathy (AVC), which affects primarily the right ventricular myocardium. Diagnosis may be obscured by physiological remodeling of the athlete heart. Healthy athletes may meet the 2010 Task Force Criteria right ventricular outflow tract (RVOT) dimension cut-offs, questioning the suitability of the modified Task Force Criteria (mTFC) in adolescent athletes. In this study, 67 male adolescent footballers undergoing preparticipation screening were reviewed. All athletes underwent a screening for resting ECG and echocardiogram according to the English FA protocol, as well as cardiopulmonary exercise testing, stress ECG, and exercise echocardiography. Athletes’ right ventricular outflow tract (RVOT) that met the major AVC diagnostic criteria for dilatation were identified. Of 67 evaluated athletes, 7 had RVOT dilatation that met the major criteria, all in the long axis parasternal view measurement. All had normal right ventricular systolic function, including normal free-wall longitudinal strain (ranging from − 21.5 to − 32.7%). Left ventricular ejection fraction ranged from 52 to 67%, without evidence of structural changes. Resting ECGs and cardiopulmonary exercise tests were normal in all individuals. In a series of healthy athletes meeting the major AVC diagnostic criteria for RVOT dilatation, none had any other pathological changes on a detailed screening including ECG, exercise testing, and echocardiography. This report highlights that current AVC echocardiographic diagnosis criteria have limitations in this population.

运动员参与前筛查的重点是通过检测主要影响右心室心肌的致心律失常性心室心肌病 (AVC) 等疾病来预防心源性猝死 (SCD)。运动员心脏的生理重塑可能会掩盖诊断。健康运动员可能符合 2010 年工作组标准右心室流出道 (RVOT) 尺寸截止值，质疑修改后的工作组标准 (mTFC) 在青少年运动员中的适用性。在这项研究中，对 67 名接受参赛前筛查的男性青少年足球运动员进行了回顾。所有运动员都根据英国 FA 协议接受了静息心电图和超声心动图筛查，以及心肺运动测试、压力心电图和运动超声心动图检查。确定了符合主​​要 AVC 扩张诊断标准的运动员右心室流出道 (RVOT)。在评估的 67 名运动员中，7 名 RVOT 扩张符合主要标准，均在长轴胸骨旁观测量中。所有人都有正常的右心室收缩功能，包括正常的游离壁纵向应变（范围从 - 21.5 到 - 32.7%）。左心室射血分数从 52% 到 67% 不等，没有结构变化的证据。所有个体的静息心电图和心肺运动试验均正常。在一系列符合 RVOT 扩张主要 AVC 诊断标准的健康运动员中，在包括心电图、运动试验和超声心动图在内的详细筛查中，没有人出现任何其他病理变化。
