COVID 19 pandemic has induced a large sedentarism in several kinds of sports. Some peculiar categories of athletes could particularly suffer from a prolonged inactivity as those affected by minimal cardiopathies as bicuspid aortic valve (BAV) athletes. This study aims to verify the myocardial performance in a restricted group of BAV athletes compared to a control group of agonistic athletes evaluated by traditional echocardiography and deformation parameters. 2D standard and deformations parameters were measured at rest conditions in BAV athletes and controls. Particularly EF, LVDD/LVS diameters, GLS rotation and twisting were considered as myocardial performance data; E/A, E1 and A1 as diastolic ones. All the 2D standard parameters measured were within the normal range in both groups, especially the EF value. Significant differences were found in the diastolic function with reduced values of E and E1 waves in BAV vs. controls. The strain analysis showed a significant reduction in GLS measured in 2C, 3C, 4C in BAV if compared to controls, while no significant differences were found in torsional and rotational parameters. These results are suggestive for a potential long term negative impact of inactivity on cardiac performance more evident in BAV athletes, if compared to athletes with normal aortic valve. GLS of LV and RV can be considered as a predictive parameter of this mild dysfunction and assumed as follow-up parameter to restore a progressive training.
新冠疫情导致多种体育项目出现大量久坐不动的情况。某些特殊类别的运动员可能尤其会因长时间不活动而受苦，比如患有轻度心脏病的运动员，如二叶式主动脉瓣（BAV）运动员。本研究旨在通过传统超声心动图和变形参数，对比一组受限的BAV运动员与一组竞技运动员对照组，以验证心肌功能。在静息状态下测量BAV运动员和对照组的二维标准参数及变形参数。特别地，将射血分数（EF）、左心室舒张末期内径/左心室收缩末期内径（LVDD/LVS）、左心室整体纵向应变（GLS）旋转和扭转视为心肌功能数据；将E/A、E1和A1视为舒张功能数据。两组测量的所有二维标准参数均在正常范围内，尤其是EF值。在舒张功能方面发现了显著差异，BAV组与对照组相比，E波和E1波值降低。应变分析显示，与对照组相比，BAV组在2腔、3腔、4腔测量的GLS显著降低，而扭转和旋转参数未发现显著差异。这些结果表明，与主动脉瓣正常的运动员相比，不活动对BAV运动员心脏功能的潜在长期负面影响更为明显。左心室和右心室的GLS可被视为这种轻度功能障碍的预测参数，并作为恢复渐进性训练的随访参数。
