Abstract

It is extremely rare to encounter primary malignant tumors of the heart. Rhabdomyoma constitutes approximately 20% of all primary malignant tumors of the heart. Rhabdomyoma commonly arises from the ventricular wall, and rarely, they arise from the atrial wall and mimic symptomatic atrioventricular valve stenosis. We describe an extremely rare case of left atrial (LA) rhabdomyosarcoma detected during the transesophageal echocardiography arising from the posterior wall of the left atrium protruding into the left ventricle causing obstruction of the mitral valve. Our case is a rare case of LA rhabdomyosarcoma presenting with mitral inflow obstruction and symptomatically mimicking severe rheumatic mitral stenosis with atrial fibrillation and fast ventricular rate with orthopnea secondary to LA failure and passive pulmonary venous congestion.
一例罕见的左心房横纹肌肉瘤病例,表现为严重的风湿性二尖瓣狭窄,伴有心房颤动、快速心室率和左心房衰竭
心脏原发性恶性肿瘤极为罕见。横纹肌瘤约占所有心脏原发性恶性肿瘤的 20%。横纹肌瘤通常发生于心室壁,也有极少数发生于心房壁,并模仿症状性房室瓣狭窄。我们描述了一例极为罕见的左心房(LA)横纹肌肉瘤病例,该瘤在经食道超声心动图检查中被发现,它从左心房后壁突入左心室,导致二尖瓣阻塞。我们的病例是一个罕见的LA横纹肌肉瘤病例,表现为二尖瓣流入道阻塞,症状类似严重的风湿性二尖瓣狭窄,伴有心房颤动和快速心室率,并因LA衰竭和被动肺静脉充血而出现呼吸困难。
