探讨超声心动图在婴幼儿原发性心脏肿瘤诊断中的应用价值。

选取26例疑似原发性心脏肿瘤婴幼儿，均行超声心动图检查，完善相关检查后，经手术或穿刺活检明确诊断，分析超声心动图对原发性心脏肿瘤的诊断价值。

26例疑似心脏肿瘤患儿中，1例确诊为原发性心脏肿瘤，属心脏黏液瘤(良性)；25例确诊为心内膜炎，其中19例伴瓣膜赘生物。超声心动图诊断2例原发性心脏肿瘤，其中1例为心内膜炎赘生物误诊为心脏肿瘤，诊断敏感度为100.0%，特异度为96.0%，与病理诊断符合率为96.15%。

超声心动图诊断婴幼儿原发性心脏肿瘤具有较高敏感度，可为临床正确诊断提供客观依据，有利于治疗方案的制定与实施。

To explore the value of echocardiography in the diagnosis of primary cardiac tumors in infants and young children.

Twenty-six infants suspected as primary cardiac tumors were selected and examined by echocardiography. After completing the relevant examinations, the diagnosis was confirmed by operation or puncture biopsy. The diagnostic value of echocardiography in primary cardiac tumors was analyzed.

In 26 children suspected as cardiac tumors, 1 was diagnosed as primary cardiac tumors, belonging to cardiac myxoma (benign); 25 were diagnosed as endocarditis, of which 19 were associated with valvular vegetation. Two cases of primary cardiac tumors were diagnosed by echocardiography. One case of endocarditis was misdiagnosed as cardiac tumors. The diagnostic sensitivity and specificity were 100.0% and 96.0% respectively. The coincidence rate with pathological diagnosis was 96.15%.

Echocardiography has a high sensitivity in the diagnosis of primary cardiac tumors in infants and young children, which can provide objective basis for correct clinical diagnosis and is conducive to the formulation and implementation of treatment programs.
