Mixoma ventricular direito gigante obstruindo via de saída do ventrículo direito

Abstract: Intracardiac myxoma is predominantly located in the left atrium but their location in the right ventricle is quite unusual. We present a case in which successful excision of the tumor was done through bicameral approach.Descriptors: Myxoma. Echocardiography. Ventricular septum. ResumoMixoma intracardíaco localiza-se predominantemente no átrio esquerdo, e sua localização no ventrículo direito é bastante incomum. Apresentamos um caso no qual excisão bem sucedida do tumor foi feita por meio de abordagem bicameral… Show more

“…Only 4 cases of RV myxoma have been reported in Korea; these were located in the RV free wall, the tricuspid valve, the anterior papillary muscle and the interventricular septum, causing significant flow obstruction. 3-6) Right-sided cardiac tumors can present with symptoms and signs of right heart failure or RVOT obstruction, and, particularly in the case of RV myxoma, complications of vena cava syndrome, pulmonary embolism and RV dysfunction have been reported 2). The tumor mass in this case was originated from the RVOT, and no flow acceleration was observed by color Doppler.…”

“…The majority of myxomas (75%) are located in the left atrium, whereas RV myxoma is only found in 2-4% of cases, and RVOT myxoma is quite rare 2). Only 4 cases of RV myxoma have been reported in Korea; these were located in the RV free wall, the tricuspid valve, the anterior papillary muscle and the interventricular septum, causing significant flow obstruction.…”

“…Czapek, in 1891, was among the first to provide a pathological description of a RV myxoma. Almost 70 years passed before Kishimoto & Sakaibori described another similar tumor, which was recognized at autopsy [ 7 ]. In adults, the primary differential diagnosis for a solitary, intracavitary cardiac mass includes thrombus, myxoma, lipoma and non-myxomatous neoplasms, most of which are malignant [ 8 ].…”

“…6 O ecodopplercardiograma é o método mais comumente utilizado para o diagnóstico, podendo quantificar o tamanho, a forma, a mobilidade, a localização e o sítio de inserção, bem como suas relações anatômicas. 5,7 A RMC pode ser utilizada adicionalmente, fornecendo informações importantes, no que diz respeito ao diagnóstico diferencial dos tumores cardíacos. Sua apresentação mais comum se caracteriza por uma massa isointensa em T1 e hiperintensa em T2, com focos de hipointensidade em uma das duas sequências.…”

“…Casos de mixomas múltiplos são mais observados em pacientes com complexo de Carney. 4,5 Quando presentes, as manifestações clínicas são diversas e relacionadas a obstrução intracardíaca, embolização sistêmica e sintomas sistêmicos ou constitucionais. Dispneia e ortopneia, decorrentes do aumento da pressão venocapilar pulmonar, são frequentes, além de lipotimia e síncope, pela obstrução transitória do enchimento do Ventrículo Esquerdo (VE).…”
