myocardial infarction as complication of left atrial Myxoma
International Journal of Cardiology, 2005Co-Authors: S Braun, H Schrotter, K Reynen, C Schwencke, Ruth H StrasserAbstract:Although cardiac Myxomas are histologically benign, they tend to form emboli and cause intracardiac obstruction, so that they must be classified as potentially fatal tumors of the heart. The probability of arterial embolism is closely correlated with the morphology of the tumor. Thus, villous Myxomas are more fragile and form emboli more often. Nuclear spin tomography and echocardiographic cine-mode sequences provide impressive images of the potential for embolism. It appears that coronary embolism may be more frequent in the group of Myxoma patients than generally is assumed. These may present as acute myocardial ischemia with the typical clinical symptoms of acute myocardial infarction, as a silent infarct, shock, syncope or as sudden cardiac death. Besides our case report this paper will give an overview on published data on coronary embolism in patients with atrial Myxoma. Interestingly there is a tendency for spontaneous recanalization of the obstructed coronary vessels, perhaps because of the tumors' tissue composition. Therefore it is reasonable to perform transoesophageal echocardiography to check out embolic sources like Myxoma, when pathogenesis of myocardial infarction remains unclear after coronary angiography.

Preoperative Emboli in a Pregnant Woman with Myxoma
Shiraz University of Medical Sciences, 2016Co-Authors: Freidoun Sabzi, Reza FarajiAbstract:The left atrium is the most common location of Myxomas, which are benign tumors. Only a few cases of Myxomas in pregnancies have been reported. Our thorough medical literature search showed only 17 reported cases in the course of pregnancy. Myxomas during pregnancy and in the preterm period constitute a serious phenomenon that can mimic an early sign of a life-threatening pathology like severe mitral stenosis. We describe a 33-year-old woman, who presented with acute dyspnea to a gynecology center and was referred to our hospital for further evaluation of pulmonary embolism. Transthoracic echocardiography showed a huge left atrial Myxoma, and computed tomography scan illustrated paradoxical pulmonary embolism in the left upper lung lobe via a large patent foramen ovale. The tumor required urgent cardiac surgery. In this article, we review causes of dyspnea in pregnancy and the cardiovascular effects of Myxomas in pregnancy. We also describe the pathophysiological effects of cardiopulmonary bypass on the mother, fetus, and the feto-placental system during open-heart surgery. We performed a successful surgical resection of a Myxoma in a pregnant woman. Given the rarity of such cases, individual multidisciplinary assessment and management strategies are essential

Radiation induced Myxoma of superior vena cava origin presenting as a right atrial mass
'Journal of Nepal Medical Association (JNMA)', 2014Co-Authors: Feridoun Sabzi, Reza FarajiAbstract:Myxomas are the most common benign cardiac tumors. Myxomas are more common in the left heart chamber than the right side chamber. An extracardiac origin presenting as a right atrial mass is very rare. Right-sided tumors are considerably less common than left-sided tumors, and however Myxoma of great vessels origin presenting as right atrial masses are rare but radiation induced villous Myxoma in superior vena cava (SVC) is exceedingly rare tumor. A case of radiation induced Myxoma originating in a previously undescribed location and presenting as a right atrial mass is reported. Keywords: Myxoma; right atrial; vena cava.

Myxoma of the superior vena cava origin presented as a right atrial mass.
The journal of Tehran Heart Center, 2013Co-Authors: Feridoun Sabzi, Babak NasiriAbstract:Myxomas are the most common benign cardiac tumors. Myxomas are more common in the left heart chamber than the right side chamber. An extracardiac origin presenting as a right atrial mass is very rare. We present a case of Myxoma originating in the superior vena cava (SVC) in a 24-year-old man, who underwent surgical resection. Preoperative two-dimensional echocardiography demonstrated a mass in the right atrium. Intraoperatively, the tumor was found to have originated from the SVC orifice. The tumor was excised from the SVC by opening the one-third proximal portion of the SVC. Pathological examination revealed a Myxoma, and one-year follow-up showed no evidence of the recurrence of any tumors in the SVC.

large left atrial Myxoma presented as fever of unknown origin a challenging diagnosis and a review of the literature
Cardiovascular Pathology, 2007Co-Authors: Gerasimos Gavrielatos, Konstantinos P Letsas, Loukas K Pappas, Panagiotis Dedeilias, Elias Sioras, Fotis KardarasAbstract:Myxoma is the most common type of primary tumors of the heart in adults. The majority of patients with Myxomas may experience symptoms due to central or peripheral embolism or intracardiac obstruction, while in some cases, they may be completely asymptomatic. Rarely, patients develop unusual symptoms that complicate the diagnostic evaluation. Herein, we describe the case of a 70-year-old patient with a long-lasting low-grade fever due to a large left atrial Myxoma revealed during a transthoracic echocardiography.
