A case of asymptomatic recurrence, in a 23-year old female patient, of a left atrial myxoma surgically removed 7 years previously is reported. The initial tumour, revealed by lipothymias and progressive heart failure, had been diagnosed by TM-mode echocardiography. The myxoma had been entirely removed, together with part of the atrial septum around its pedicle. The recurrent tumour was discovered by chance during routine control echocardiography. Post-surgical recurrent cardiac myxomas are uncommon (5% of the cases), and they predominate in the left atrium, like the initial tumours. They develop more rapidly and may recur several times in succession, becoming increasingly aggressive and multiple, though most of them remain benign. They are thought to result from the proliferation of myxomatous cells in clusters disseminated within the cardiac walls. Echocardiography is the key to the diagnosis; it is also used for post-surgical follow-up.
报告了一例23岁女性患者，其7年前手术切除的左心房黏液瘤无症状复发。最初的肿瘤由晕厥和进行性心力衰竭发现，通过TM型超声心动图诊断。黏液瘤已连同其蒂周围的部分房间隔一起完全切除。复发性肿瘤是在常规超声心动图检查时偶然发现的。心脏黏液瘤术后复发并不常见（占病例的5%），并且与最初的肿瘤一样，它们在左心房中占主导地位。它们生长更快，可能连续复发多次，变得越来越具有侵袭性且多发，尽管大多数仍为良性。它们被认为是由散在于心脏壁内的成簇黏液瘤细胞增殖所致。超声心动图是诊断的关键；它也用于术后随访。
