Cardiac myxomas can be fatal and left ventricular (LV) myxomas with papillary muscle and mitral valve (MV) involvement are rare. The following case is that of a 55‐year‐old woman who developed signs and symptoms of pulmonary hypertension. Imaging revealed a contractile mass in the LV that was in continuum with the papillary muscles and affected MV function. Her clinical course, radiologic, and hemodynamic findings are discussed. Finally, her surgical extraction technique is described in addition to potential complications encountered. 相似文献

Benign cardiac tumors are rare; they can present with nonspecific symptoms and represent a diagnostic challenge to the clinician. We describe an interesting case of a 26-year-old female who presented with a 6-month history of cough, breathlessness, palpitations, dizziness, and fever. Despite repeated clinical reviews in the community, diagnosis of cardiac tumor was not made until she developed decompensated cardiac failure with bilateral pleural effusions and pulmonary edema. Echocardiogram revealed an enormous left atrial mass that extended one-third into left ventricle during systole. The patient underwent successful surgical resection with histological confirmation of a benign atrial myxoma. 相似文献

Coronary artery thromboembolism: Unexpected presentation of left atrial myxoma covered with thrombus
Samet Uysal MD Ayse Zehra Karakoc MD Kadir Biyikli MD Benay Erden MD Ozkan Candan MD Gonca Gul Gecmen MD 《Journal of cardiac surgery》2020,35(8):2097-2099
Cardiac myxomas are benign primer cardiac tumors of the heart. They can be fatal with a thromboembolic presentation. Myocardial infarction is one of these unusual thromboembolic presentations. We report a patient who presented with cardiac arrest due to ventricular fibrillation related to myocardial infarction. After successful resuscitation, coronary angiography and transthoracic echocardiography were performed. A left atrial mass was observed and interpreted as a possible cause of coronary embolism leading to myocardial infarction. After surgical excision, the pathological examination confirmed myxoma, which was the essential cause of the tendency to arterial embolism. 相似文献

目的 对比采用右胸前外侧微创切口和胸骨正中切口行右心房黏液瘤切除手术的手术效果。方法 选取2005年5月至2019年12月在复旦大学附属中山医院行手术治疗的右心房黏液瘤患者共61例,其中男性25例,女性36例,年龄19~82岁,平均(53.6±13.4)岁,根据手术切口分组,45例采用胸骨正中切口(胸骨组),16例采用右胸前外侧微创切口(微创组)。采用独立样本t检验、秩和检验、Fisher精确检验比较两组手术结果。结果 两组术前资料匹配,无院内死亡患者。两组平均心肺转流时间相似,但与胸骨组相比,微创组平均手术时间、主动脉阻断时间均较短,平均机械通气时间和术后住院时间较短,引流量较少,输血率较低,差异有统计学意义。术后随访3~153个月,随访率95.6%,1例患者随访期间非心源性死亡,余患者恢复良好,随访超声心动图未见肿瘤复发。结论 两种手术入路行右心房黏液瘤切除均安全有效,术后中远期复发率低,采用右胸前外侧微创切口进行手术可缩短手术时间,减少手术创伤。 相似文献

Capsulomas comprise a category of very rare benign tumors derived from the renal capsule, the most encountered being myxomas and leiomyomas. To get more information on the histogenetic origin of these tumors, a comprehensive ultrastructural investigation on the human renal capsule has been done on kidney biopsy samples performed for nephropathologic diagnosis. The human renal capsule ultrastructure is similar to that of the mammalian renal capsule. There are two cellular layers: an inner layer made up of particular (immature) smooth muscle cells, and a second outer layer consisting of fibroblasts, collagen fibers, extracellular matrix, and telocyte-like cells. Two cases of leiomyomas of microscopic dimensions, situated beneath the capsule have been described. Data from the literature presenting the ultrastructure and perirenal location of myxomas support the affiliation of these capsulomas with the resident renal capsular cells. Based on ultrastructural studies, the authors demonstrate the presence of telocyte-like cells in the outer layer of the human renal capsule and propose distinct histogeneses for leiomyomas and for capsular myxomas as derived from the inner and outer capsular layers, respectively. 相似文献

患者男,48岁,体检发现腹腔肿物半年余,无腹痛、腹泻等。查体未见明显异常。实验室检查:血清CA125升高(181.61 U/ml)。腹部CT示肝胃间隙见约9.4 cm×7.3 cm×11.4 cm囊实性肿块,平扫CT值21 HU,边界清楚,增强后动脉期实性部分CT值42 HU(图1A),静脉期CT值93 HU。腹部MRI示肝胃间隙巨大囊实性肿块,T1WI及脂肪抑制T2WI均呈稍长信号(图1B),增强后实性部分呈渐进性明显强化,囊性部分未见强化(图1C)。影像学诊断:肝胃间隙富血供肿瘤,考虑肝脏来源。 相似文献

目的 总结心房黏液瘤摘除同期行冠状动脉搭桥的临床治疗经验。方法 回顾性分析我科2013年1月至2019年3月18例同期行心房黏液瘤摘除+冠状动脉搭桥术患者的临床资料、手术方法及预后情况。结果 所有患者均在体外循环下行房黏液瘤摘除+冠状动脉搭桥术,根据手术所见,肿瘤位置与心脏超声所见位置一致。术中所见肿瘤大小不一,形态呈分叶状、不规则形、类圆形等,质脆,多数为胶冻样,少数有完整包膜,表面可有黏液渗出或出血,少数表面出现钙化。部分肿瘤瘤体可坠入二尖瓣口或三尖瓣口。术后无死亡病例。术后低心排综合征1例,经相应的治疗而治愈;术后新发心房颤动5例,均经用胺碘酮后转复正常;二次开胸止血2例。术后随访1年,18例患者均未见瘤体复发,心功能恢复到 NYHAⅠ~Ⅱ级。结论 心房黏液瘤摘除同期行冠状动脉搭桥是治疗心房黏液瘤合并冠心病的有效方法,可取得良好的预后效果。 相似文献
