Echocardiographic examination helps to assess the structure and functioning of transplanted heart. In early post-transplantation period, the right cardiac ventricle is usually enlarged in ECHO records, and pulmonary pressure is elevated. Both size and functioning of the left ventricle are usually normal in both early and late periods following transplantation. Endomyocardial biopsy remains a basic diagnostic technique in transplant rejection. Echocardiography is a valuable non-invasive technique enabling to diagnose moderate to severe transplant rejection. The most valuable for the diagnosis of transplanted heart rejection are changes in the left ventricle diastolic indices (prolongation of relaxation time and half-life of pressures gradient across mitral valve). Remote prognosis in heart recipients depends on the progressing left ventricle dysfunction, mainly diastolic, and vasculopathy developing in the late postoperative period.
超声心动图检查有助于评估移植心脏的结构和功能。在移植后的早期，超声心动图记录中右心室通常会增大，肺动脉压力升高。移植后早期和晚期，左心室的大小和功能通常都是正常的。心内膜活检仍然是诊断移植排斥反应的基本技术。超声心动图是一种有价值的非侵入性技术，能够诊断中度至重度移植排斥反应。对诊断移植心脏排斥反应最有价值的是左心室舒张指标的变化（舒张时间延长和二尖瓣跨瓣压力梯度半衰期延长）。心脏移植受者的远期预后取决于左心室功能障碍的进展，主要是舒张功能障碍，以及术后晚期发生的血管病变。
