Abstract

Type A aortic dissection (TAAD) is a potentially life-threatening diagnosis that can present with elusive symptomatology. A high degree of clinical suspicion is necessary for prompt diagnosis and management. We describe a case of a transthoracic echo (TTE) in a non-suspicious clinic patient diagnosed with TAAD. A 66-year-old Caucasian male presented for a routine clinic visit with one episode of acute severe chest pain. An echocardiogram was ordered for further workup of hypertension and chest discomfort. The echocardiogram demonstrated an ejection fraction of 60% without significant valvular abnormalities. There was suspicion of aortic pathology, which required multiple attending to review the images. The final interpretation was TAAD with a thrombus present in the false lumen. The patient then presented to the Emergency Department. A computed tomographic angiography was performed, which subsequently confirmed the TAAD. The patient was admitted to the cardiovascular ICU and ultimately underwent a successful repair of the dissection. The patient had an unremarkable post-operative course and was ultimately discharged home. Our case demonstrated a diagnosis of TAAD by office-based TTE as the original imaging modality. While this was unconventional, a TAAD should remain on the differential diagnosis when being ordered for the patient's with uncontrolled hypertension with chest pain as a presenting symptom.

摘要

A型主动脉夹层(TAAD)是一种可能危及生命的疾病,其症状可能难以捉摸。高度的临床怀疑对于及时诊断和治疗至关重要。我们描述了一例在非可疑门诊患者中通过经胸超声心动图(TTE)诊断出TAAD的病例。一名66岁的白种男性因一次急性严重胸痛前来进行常规门诊就诊。为进一步检查高血压和胸部不适,安排了超声心动图检查。超声心动图显示射血分数为60%,无明显瓣膜异常。怀疑有主动脉病变,需要多位主治医生查看图像。最终诊断为TAAD,假腔内有血栓形成。随后患者前往急诊科。进行了计算机断层血管造影,随后证实了TAAD。患者被收入心血管重症监护病房,最终成功进行了夹层修复手术。患者术后恢复过程顺利,最终出院回家。我们的病例显示,通过门诊TTE作为初始成像方式诊断出了TAAD。虽然这并不常见,但当为以胸痛为主要症状且高血压控制不佳的患者进行检查时,TAAD仍应列入鉴别诊断。
