【摘要】 本文通过分析3例右心房恶性肿瘤致三尖瓣口梗阻的超声心动图特点，探讨其超声心动图特征。超声心动图是无创性评价心房肿瘤的敏感检查方法，通过彩色多普勒技术，可直观地观察到三尖瓣口血流动力学的异常改变，精确测量跨瓣压差，量化梗阻程度，从而辅助临床医生判断病情的严重程度，制定合理的治疗方案。更多还原

【Abstract】 By analyzing the echocardiogram characteristics of 3 cases of right atrial malignant tumors causing tricuspid obstruction, this study explored the echocardiogram features. Echocardiogram is a sensitive non-invasive examination method for evaluating atrial tumors. With color Doppler technology, the abnormal changes in the hemodynamics of the tricuspid orifice can be directly observed, the transvalvular pressure gradient can be accurately measured, and the degree of obstruction can be quantified. This can assist clinicians in judging the severity of the disease and formulating a reasonable treatment plan.更多还原
