“…Nineteen (14.3%) patients had other than cerebral artery embolisms, with systemic multiple emboli in 4 (21.1%) [ 55 , 63 , 71 , 80 ] , peripheral multiple emboli in 3 (15.8%) [ 19 , 72 , 85 ] and solitary arterial embolus in 12 (63.2%) patients [ 9 , 11 , 13 , 16 , 21 , 35 , 41 , 43 , 60 , 76 , 84 ] . The 39 affected arteries in 18 patients were listed in Table 8 .…”

“…It was the only diagnostic tool in 79 (87.8%) patients and as an adjunctive to other imaging in 11 (12.2%) patients ( Table 9 ). In one patient, the pathology of the aspirated materials by catheterized thrombectomy on day 5 after admission revealed platelet thrombus and myxomatous tissue, which aroused the suspicion of a cardiac myxoma origin [ 41 ] . Both transthoracic and transesophageal echocardiography showed a respective false negative result in one patient each [ 10 , 19 ] , the cause of the latter was a complete detachment of the cardiac myxoma [ 19 ] .…”

“…No difference was found in the mortality between patients receiving an urgent and a delayed myxoma resection ( χ 2 =5.1, P =0.167). Moreover, a staged cardiac myxoma resection was performed subsequent to other operations in 3 patients with an interval between operations of 1 [ 64 ] , 2 [ 41 ] and 4 [ 80 ] weeks, respectively. Patients were followed up for 24.3±27.8 (range, 1-132; median, 12) months ( n =59).…”

ObjectiveThe clinical features of cardiac myxoma stroke have not been sufficiently described. Debates remain concerning the options and timing of treatment and the clinical outcomes are unknown. This article aims to highlight the pertinent aspects of this rare condition.MethodsData source of the present study came from a comprehensive literature collection of cardiac myxoma stroke in PubMed, Google search engine and Highwire Press for the year range 2000-2014.ResultsYoung adults, female predominance, single cerebral vessel (mostly the middle cerebral artery), multiple territory involvements and solitary left atrial myxoma constituted the outstanding characteristics of this patient setting. The most common affected cerebral vessel (the middle cerebral artery) and areas (the basal ganglion, cerebellum and parietal and temporal regions) corresponded well to the common manifestations of this patient setting, such as conscious alteration, ataxia, hemiparesis and hemiplegia, aphasia and dysarthria. Initial computed tomography scan carried a higher false negative rate for the diagnosis of cerebral infarction than magnetic resonance imaging did. A delayed surgical resection of cardiac myxoma was associated with an increased risk of potential consequences in particular otherwise arterial embolism. The mortality rate of this patient population was 15.3%.ConclusionCardiac myxoma stroke is rare. Often does it affect young females. For an improved diagnostic accuracy, magnetic resonance imaging of the brain and echocardiography are imperative for young stroke patients in identifying the cerebral infarct and determining the stroke of a cardiac origin. Immediate thrombolytic therapy may completely resolve the cerebral stroke and improve the neurologic function of the patients. An early surgical resection of cardiac myxoma is recommended in patients with not large territory cerebral infarct.

“…[14] The sensitivity of transthoracic echocardiography in diagnosing myxoma is 95%, and the sensitivity in transesophageal echocardiography is 100%. [15] However, when the patient is critical, the poor quality of the images caused by position-restricted bedside instrument examinations or the atypical ultrasound images of myxoma can still lead to misdiagnosis of myxoma, [16] which delays treatment and leads to a life-threatening situation.

A case report of left atrial myxoma-induced acute myocardial infarction and successive stroke

Rationale:Left atrial myxoma is a common primary cardiac tumor, however, due to poor image quality or atypical myxoma images, it is often misdiagnosed by echocardiograph. A case of left atrial myxoma being misdiagnosed as a thrombus, which successively caused acute myocardial infarction (AMI) and stroke, is very rare. Contrast-enhanced echocardiography can play an important role in definitive diagnosis.Patient concerns:A 44-year-old woman was diagnosed AMI because of chest pain with no significant stenosis in the coronary arteries. One month later, the patient was suddenly found unconscious, magnetic resonance imaging (MRI) showed acute multiple cerebral infarctions in the left cerebral hemisphere.Diagnoses:Left atrial myxoma, acute myocardial infarction, and stroke.Interventions:The patient was given a cardiac surgery for tumor resection, the mass was surgically removed and histopathologic findings showed myxoma.Outcomes:After several weeks of rehabilitation, the patient was able to resume daily activities without chest discomfort or dyspnea. One year later, echocardiography showed no recurrence of left atrial myxoma. The patient generally was in good condition.Lessons:Although myxoma is mostly benign, this patient occurred AMI and stroke because of misdiagnosis. Comprehensive assessments should be performed with multiple imaging methods for cardiac masses. If necessary, contrast-enhanced echocardiography should be used to clarify, so as not to delay the timing of surgery and bring potential risk of death to patients.

“…They are rarely found at other sites within the cardiac cavities, such as the ventricles, although they occasionally involve a cardiac valve [1]. Their clinical presentations can be varied, with local cardiac hemodynamic consequences, valvular insufficiency or even embolic phenomena [2]. We report a rare case of left atrial and right ventricular and left ventricular myxomas.…”

Myxomas are common cardiac tumors, which are usually managed by complete excision. We report a case of myxomas at different stages of development found simultaneously in the left atrium and both ventricles. The patient underwent successful surgical excision of all myxomas and there has been no clinical or echocardiographic evidence of recurrence or valvular insufficiency in 6 months of follow-up.
