Left Atrial Myxoma Hypervascularized from the Right Coronary Artery: An Interesting Cath Lab Finding.

ABSTRACT: Primary cardiac tumors are rare and approximately half of them are atrial myxomas. They rarely remain asymptomatic, especially if large. The imaging of a myxoma by contrast dye during coronary angiography is an infrequent sign, which clarifies the vascular supply of the tumor. We report herein an interesting and rare case of a left atrial myxoma hypervascularized from the right coronary artery.

A giant left atrial myxoma neovascularized from the right coronary artery.

Project description:Myxomas are benign and the most common tumors of the cardiac muscle (Reynen, 1995). They are predominantly located in the left atrium. Clinical manifestations may vary according to the localization and the size of the myxoma. On the other hand, imaging of a myxoma by contrast dye during coronary angiography is a rare sign, which displays the vascular supply of the tumor. Here, we report the case of a 51-year-old man presenting with presyncope and palpitations due to a giant left atrial myxoma having its vascular supply from the right coronary artery (RCA).

Right Atrial Myxoma with Coexistent Coronary Artery Disease - A Rare Combination.

Project description:Atrial myxomas are the most common primary heart tumors. Two-dimensional echocardiography is the diagnostic procedure of choice. The majority of myxomas are located in the left atrium. Myxoma in the right atrium is an uncommon location. The co-occurrence of right atrial myxoma with atherosclerotic coronary artery disease (CAD) is uncommon. In our case, right atrial myxoma was associated with CAD, which makes it a unique case because very few cases of right atrial myxoma coexistent with CAD are described in literature.

Left Atrial Myxoma Following Coronary Artery Bypass Grafting with Patient Coronary Arterial Grafts: a Rarity.

Project description:The development of left atrial myxoma after coronary artery bypass graft surgery is a rare entity. A 60-year-old man with previous off-pump coronary artery bypass grafting four years ago with patent coronary grafts was diagnosed with left atrial mass. The patient underwent successful resection of the same through minimally invasive right anterolateral thoracotomy. Histopathology of the atrial mass confirmed the diagnosis of atrial myxoma.

Concomitant Multiple Coronary Artery Embolizations and Bilateral Lower Limb Ischemia due to Dislodged Left Atrial Myxoma-Like Thrombus.

Project description:The differential diagnosis of intracardiac masses is challenging. Cardiac myxomas are benign primary heart tumors and most often are confused with thrombi in diagnosis. In some cases, the embolic complication of intracardiac masses can be fatal. We present a patient who had two nightmare complications simultaneously. A mobile left atrial mass detected and decided surgical excision. But the mass had vanished one day after and caused ST-elevation myocardial infarction (STEMI) and bilateral lower limb ischemia.

Giant Intrapericardial Myxoma Adjacent to the Left Main Coronary Artery.

Project description:A 62-years-old woman was admitted to the hospital because of chronic cough, expectoration of thick mucus, hoarseness and tightness in the precordial area. Computed Tomography (CT) examination revealed the presence of a giant intrapericardial tumor with the dimensions of 80 × 38 × 32 mm. It was located anteriorly and laterally to the left atrium, posteriorly to the pulmonary trunk and the ascending aorta. This hypodense change modeled the left atrium without evidence of invasion. CT coronary angiography and 3-dimensional reconstruction were applied to enable precise planning of cardiac surgery. CT evaluation confirmed that it is possible to remove the tumor without damage to the adjacent left main coronary artery. The patient underwent cardiac surgery with sternotomy and cardiopulmonary bypass. A cohesive, smooth, vascularized tumor pedunculated to the left atrial epicardium was visualized. The location and dimensions corresponded to those determined by CT scan examination. The entire tumor was successfully dissected together with adjacent adipose and fibrous tissue. Histological evaluation revealed the presence of myxoid cells, blood vessels, degenerative changes, and microcalcifications embedded in profuse hyalinized stroma. Those histological features enabled identification of the intrapericardial tumor as a myxoma. Follow-up CT examination did not demonstrate any signs of recurrence of the myxoma. According to our knowledge, a myxoma located inside the pericardial sac has never been described before.

An incidental finding of a right atrial myxoma with undiagnosed Ebstein anomaly: a case report.

Project description:BackgroundEbstein anomaly (EA) is a rare congenital abnormality of the tricuspid valve which can lead to progressive right heart dilatation and arrhythmias. While often seen in conjunction with other congenital cardiac lesions, such as atrial septal defects, it is not normally associated with atrial myxomas.Case summaryWe present a case report of an incidental finding of a right atrial myxoma in the context of undiagnosed EA, in a 16-year-old male who presented with appendicitis. Subtle cardiomegaly on routine chest X-ray prompted further investigation, which demonstrated characteristic findings of both conditions and culminated in surgical repair using the Cone procedure. At 4-month follow-up, the patient was asymptomatic, and transthoracic echocardiography demonstrated a mean gradient of 4.5 mmHg across the tricuspid valve with mild regurgitation.DiscussionThe combination of EA with right-sided myxoma is exceedingly rare, and, in this case, it may be that the apical displacement of the tricuspid valve was protective against right atrioventricular obstruction. We are reminded that although subtle abnormalities on routine investigations can be of limited significance, they can also indicate more serious underlying pathology and so consideration should be given to an appropriate cascade of further investigations to yield a timely diagnosis and enable prompt treatment.
