Ressecção de mixoma ventricular esquerdo após acidente vascular cerebral embólico

Abstract

Ressecção de mixoma ventricular esquerdo após acidente vascular cerebral embólicoResection of left ventricular myxoma after embolic stroke Abstract Cardiac myxoma is the most common primary tumor of the heart. The tumor is located mainly in the left atrium but can arise from any heart chamber. Clinical symptoms are variable but dyspnea and embolism are the most frequent. We report a case of a young man that had embolic ischemic stroke caused by a large left ventricular myxoma. The patient underwent surgery three weeks after the stroke. The tumor was carefully resected without fragmentation. Surgical treatment was effective. We emphasize the rarity of this location together with a review of the current literature. Descriptors

Atypical size and location of a right atrial myxoma: a case report

“…Cardiac tumors represent 0.2% of all tumors found in humans [1]. These tumors are divided into primary and secondary or metastatic.…”

“…Approximately 75% are benign, and approximately 50% are myxomas, which have an incidence of 0.0017% in the general population. Histologically, these are real tumors, derived from multipotent mesenchymal cells of the subendocardium [1-4]. …”

“…Once a cardiac myxoma is diagnosed, surgical excision should be performed without delays because of the constant risk of thromboembolic events [1,10]. Generally, surgical treatment is definitive and recurrence is uncommon.…”

A Large Left Ventricle Myxoma: Presenting with Epigastric Pain and Weight Loss

“…According to previous studies, most myxomas grow in the left atrium (70–90%), and only a small percentage (15–20%) is found in the right atrium. Tumors may rarely originate from the right or left ventricles [13]. …”

“…Symptoms such as constipation, nausea, vomiting, and anorexia may be related to the production of interleukin 6 (IL-6), a principal mediator of the acute phase protein response [9, 13]. The type and duration of clinical presentation of myxoma depends on tumor size, location, mobility, growth rate, and histopathologic features [4, 7].…”
