A comparison between praecordial and transoesophageal cross-sectional echocardiography was undertaken in the follow-up of 14 patients who had previously undergone surgical excision of atrial myxoma. The mean interval between surgery and follow-up was 39 months. Evidence of recurrent tumour was seen in two patients by transoesophageal echocardiography but went undetected in one of these using the praecordial approach. Clear visualisation of the atria and interatrial septum was possible in all remaining cases using transoesophageal echocardiography and this allowed confident exclusion of tumour recurrence. Using praecordial echocardiography, technically inadequate studies meant that this was not possible in 4 patients. The significant late recurrence rate of excised atrial myxomas, emphasises the need for serial, postoperative echocardiographic studies. Praecordial echocardiography may be unreliable in the detection of recurrent atrial myxoma in its early stages and for this reason transoesophageal echocardiographic follow-up is justified in high risk patients.
对14例曾接受心房黏液瘤手术切除的患者进行了随访，比较了心前区和经食管横断面超声心动图。手术与随访之间的平均间隔时间为39个月。经食管超声心动图在两名患者中发现了肿瘤复发的证据，但其中一名患者采用心前区检查方法未检测到。在所有其余病例中，经食管超声心动图都能清晰显示心房和房间隔，从而能够可靠地排除肿瘤复发。使用心前区超声心动图时，技术上不充分的检查意味着4例患者无法做到这一点。切除心房黏液瘤后显著的晚期复发率强调了术后进行系列超声心动图检查的必要性。心前区超声心动图在早期检测复发性心房黏液瘤时可能不可靠，因此对于高危患者，经食管超声心动图随访是合理的。
