One of the purposes of echocardiography is to determine the nature of a space-occupying lesion. The conventional transthoracic echocardiogram (TTE) is the preferred method for the diagnosis of cardiac space-occupying lesions as it can reveal the baseline information. For patients with poor conditions, however, TTE cannot clearly display the boundary, it has a limited role in determining the nature of the lesions.
A 47-year-old woman presented with intermittent fever for 7 days and chest distress/shortness of breath for 5 days.
In our current case, we inferred the nature of space-occupying lesions in the left atrium more accurately using transesophageal echocardiography (TEE) than TTE, which may offer diagnostic evidence for surgical treatment.
The patient underwent surgical resection of the left atrial tumor and reconstruction of the left atrial wall. However, the patient's posterior lobe of the mitral valve was infiltrated by tumor, which was difficult to completely remove.
Echocardiography was performed 3 months after surgery and the tumor recurred in the posterior lobe of the mitral valve. Although almost all tumors have been removed by surgery, the average survival time is often less than 1 year, as it is difficult to completely remove and easy to relapse with poor prognosis.
Transesophageal echocardiography (TEE) plays a relatively more important role in the determination and differential diagnosis of cardiac space-occupying lesions.
超声心动图的目的之一是确定占位性病变的性质。传统的经胸超声心动图（TTE）是诊断心脏占位性病变的首选方法，因为它可以提供基线信息。然而，对于条件较差的患者，TTE 无法清晰显示边界，在确定病变性质方面作用有限。
一名 47 岁女性因发热 7 天和胸闷/呼吸急促 5 天就诊。
在我们的病例中，我们使用经食管超声心动图（TEE）比 TTE 更准确地推断左心房占位性病变的性质，这可能为手术治疗提供诊断依据。
患者接受了左心房肿瘤切除术和左心房壁重建术。然而，患者二尖瓣后叶被肿瘤浸润，难以完全切除。
术后 3 个月行超声心动图检查，发现二尖瓣后叶肿瘤复发。尽管手术几乎可以完全切除肿瘤，但平均生存时间通常不到 1 年，因为难以完全切除，容易复发，预后较差。
经食管超声心动图（TEE）在心脏占位性病变的确定和鉴别诊断中发挥着相对更重要的作用。
