A 38-year-old male was admitted to our institution with left atrial myxoma complicated with acute myocardial infarction. The patient had no risk factor for coronary artery disease. A transthoracic echocardiographic study revealed the presence in the left atrium of an echogenic, mobile mass, compatible with myxoma. There were no endocrine hyperactivity, any other tumor and family history. Coronary angiography revealed normal coronary arteries and aorto-coronary bypass surgery was not required in this patient. The tumor was successfully removed surgically. In conclusion, there could be no other etiologic possibility identified and therefore left atrial tumor causing coronary embolization and MI was considered the most likely event in this patient. 相似文献

BACKGROUNDCardiac embolism is a common cause of ischemic stroke in young adults. Neurological complications associated with atrial myxoma most frequently include cerebral infarct due to embolus. Early complete resection of giant cardiac myxoma is the key to its treatment and prevention of stroke recurrence.CASE SUMMARYA 42-year-old, previously healthy woman was admitted to the hospital with sudden-onset inability to speak and right-sided hemiplegia. While sweeping the floor 2 h prior to hospital admission, the patient developed sudden inability to express herself or understand what others were saying, accompanied by dyskinesia of the right limb, inability to walk or hold objects, and involuntary choreiform movements of the left upper limb. The patient was diagnosed with cerebral embolism and cardiac myxoma, complicated by left middle cerebral artery occlusion. The acute stroke was treated with intravenous thrombolytic therapy and arterial embolectomy as a bridging therapy to open resection of left atrial cardiac myxoma. The patient condition improved remarkably following initial thrombolysis and embolectomy and subsequently underwent emergency open resection of the atrial cardiac myxoma. She had no recurrence during 1-year follow-up.CONCLUSIONStrong consideration should be given to urgent intravenous thrombolysis (rt-PA, alteplase) in young adult stroke patients at the time of hospital admission. The present case demonstrated a highly successful outcome that combined thrombolysis and arterial embolus retrieval as a bridge to early complete resection of a giant cardiac myxoma for both stroke treatment and recurrence prevention. 相似文献

We have reported a case of left atrial myxoma in association with an atrial septal defect in a patient followed up over a number of years for recurrent sterile pleural effusions and chronic obstructive lung disease of undetermined cause. During hospitalization for pneumonia, an intracardiac mass and atrial septal defect were found by echocardiography, and verified at operation to be a left atrial myxoma. 相似文献

A 67-year-old woman was referred to our hospital with a diagnosis of deep vein thrombosis due to surgery for left patellar fracture. Deep vein thrombosis resolved with thrombolytic therapy. Transthoracic echocardiogram revealed a mobile left atrial tumor. Transesophageal echocardiography showed a fragile tumor with multiple fronds, implying a papillary fibroelastoma. Because this patient had a history of cerebral embolism, urgent surgery was scheduled. The excised tumor showed a sea anemone-like appearance in saline, which was similar to that of a papillary fibroelastoma. However, histological examination revealed the features of a myxoma and not papillary fibroelastoma. Herein, we illustrate a very rare case of left atrial myxoma with papillary fibroelastoma-like features in terms of both echocardiographic and gross findings. 相似文献

Cardiac myxomas are rare tumors which may present differently. Left atrial myxoma is an entity from anatomopathological and clinical aspects. To the best of our knowledge, only 2 cases of infected left atrial myxomas treated surgically have been reported in the last 6 years. Herein, we present a patient with a left atrial myxoma prolapsing into the left ventricle in the diastolic phase, which was infected with Streptococcus viridans. Combined therapy, consisting of surgical management and antimicrobial therapy, was used. Clinical presentation, diagnosis and treatment are reviewed. 相似文献

We present the case of a 37-year-old male patient with a multicentric myxoma admitted to hospital with dyspnoea, syncope and chest pain. Physical examination revealed a grade 3/6 systolic murmur at the left lower sternal border and diffuse bilateral lung rales. Transthoracic echocardiography and thoraco-abdominal computed tomography revealed a right atrial mass and a right ventricular mass obstructing the outflow tract. The patient underwent urgent surgical treatment. At operation, a solitary right atrial myxoma and a right ventricular myxoma originating from the tricuspid valve and attached to the free wall of the right ventricle were seen. The tumours were successfully excised and the tricuspid valve was replaced with a No. 33 Omnicarbon metallic valve. The right ventricular free wall was repaired with a glutaraldehyde-treated pericardial patch. Histopathological examination of the tumours confirmed the diagnosis of myxoma. Post-operative recovery was uneventful and there was no recurrence after 1 year's follow-up. 相似文献

A 65-year-old-man was referred for echocardiographic examination because of palpitations. He had a history of an atrial septal defect surgically treated with an artificial synthetic polyester textile fiber patch. TTE showed a large, mobile mass in a dilated left atrium. The attachment site of the mass was not clear by transthoracic approach, and it was difficult to diagnose the mass as a thrombus or a myxoma from the nature of the echocardiographic findings. Transesophageal echocardiography clearly demonstrated that the mass was attached to the patch closing the atrial septal defect and the mass was confirmed as thrombus at surgery. A patient with left atrial thrombus in whom transesophageal echocardiographic demonstration of the attachment of the left atrial mass to a patch closing an atrial septal defect served as an essential clue leading to accurate diagnosis is reported. Transesophageal echocardiography is feasible to evaluate the attachment site of a left atrial mass and to lead to an accurate diagnosis. 相似文献

Cardiac hydatid cysts are very rare in hydatid cyst disease. We report herein a case of hydatid cyst mimicking left atrial myxoma. A 78-year-old woman was admitted to our hospital with complaint of dyspnea and signs pulmonary edema and mitral stenosis. Echocardiography showed left atrial mobile, mostly solid mass with wall calcifications moving towards the orifice of the mitral valve. We also found loculated giant hepatic and right pulmonary cysts. We aimed to report this case because of mimicking mitral stenosis and left atrial myxoma and causing heart failure. 相似文献

We report a case of a left atrial mass echocardiographically mimicking myxoma, in a patient with renal cell carcinoma. The mass was pathologically confirmed to be metastatic carcinoma, which had entered the left atrium from a mediastinal lymph node, via direct invasion of a pulmonary vein, illustrating the potential for unusual routes of tumor spread into the heart and the importance of obtaining a tissue diagnosis in such cases. 相似文献

We explore the association between the site of attachment of nonfamilial left atrial myxoma and it’s recurrence. Forty-three
(11 male and 32 female; mean age, 55.9±13.6 years) of 49 consecutive patients with nonfamilial left atrial myxoma who had
been evaluated with preoperative echocardiography, X were available for postoperative follow-up with transthoracic echocardiography,
transesophageal echocardiography, or both, for an average period of 85.2±54.2 months (range, 6.5 to 215.5 months). We compared
preoperative clinical and echocardiographic features of recurrent and nonrecurrent myxomas. Three (7%) of the 43 cases of
atrial myxoma recurred at the same site after 24.1±7.6 months. Involvement of the mitral valve annulus or mitral valve leaflet
(3 vs 0,p<0.001) was observed in the recurrent myxomas, but the two groups did not differ significantly in any other clinical features,
laboratory data, or echocardiographic features of the recurrent and nonrecurrent myxoma. Preoperative echocardiographic observation
of involvement of the mitral valve annulus or mitral valve leaflet may predict recurrence after surgery. Regular follow-up
echocardiography was useful in the early detection of recurrence. 相似文献

Cardiac myxomas accompanied by multiple embolic complications in cerebral and visceral arteries have been well documented in scientific literature. However, cerebral artery aneurysms have rarely been reported as a possible embolic complication of myxomas. This study describes a patient who had multiple episodes of cerebral infarctions and was found to have left atrial myxoma with old renal infarction as well as cerebral and coronary artery aneurysms. This is the first case report of coronary artery aneurysms associated with cardiac myxoma. 相似文献

The echocardiographic diagnosis of a left atrial myxoma is described. This was later confirmed by cardiac catheterization and the tumor removed at operation. The myxoma was found to arise from the free left atrial wall and no such case diagnosed by echocardiography has previously been reported. The possibility of false negative and false positive echocardiographic findings is discussed. Echocardiography is an accurate, atraumatic, and rapid diagnostic technique which can be used as a simple screening procedure in cardiac evaluations. 相似文献

Myxoma is the most common tumor in the heart. A typical myxoma is relatively straightforward to diagnose. However, certain cardiac myxomas have rare features. We report three extremely rare cases of cardiac myxoma. One case involved a myxoma that originated from the annulus of the tricuspid after valvuloplasty, one case involved myxomas associated with left atrial thrombus and severe mitral stenosis, and the third case involved myxoma combined with severe calcification. All three cases were diagnosed by echocardiography and pathology. We also review clinical presentations and diagnostic characteristics of cardiac myxomas. 相似文献

Atrial myxomas often show contrast enhancement following administration of intravenous gadolinium, whereas thrombus appears as a hypointense structure, typically without any contrast enhancement. This case report presents a diagnostic challenge involving a recently developed left atrial mass in which echocardiography and cardiac MRI provided discordant results. While the morphological characteristics of the new left atrial lesion were suggestive of myxoma, the signal characteristics and behavior following intravenous gadolinium at MR, and, in particular, the rapid interval appearance of the lesion, prompted consideration for left atrial thrombus. Subsequent intra-operative and histopathologic evaluation proved the mass to be a left atrial myxoma. 相似文献
