Right atrial myxoma presenting as Budd-Chiari syndrome

Eustachian valve myxoma: a rare cause of Budd-Chiari syndrome

Budd-Chiari syndrome caused by right atrial myxomas are extremely rare. We report the case of a patient who presented with chronic liver disease who upon consequent investigation was found to have a mass occupying the right atrium and ventricle consistent with cardiac tumour. Intraoperatively, a giant mass was removed from the right atrium with the tumour stalk originating from the Eustachian valve. Histologic findings were consistent with myxoma.

Ascites and Other Extracardiac Manifestations Associated with Right Atrial Myxoma

Right atrial myxomas are rare intracardiac tumors that often pose difficulties in diagnosis. Right ventricular failure and ascites ensuing from tricuspid valve orifice obstruction are potentially dangerous complications. Early diagnosis of cardiac myxoma is important since surgical treatment leads to disappearance of all symptoms with a low rate of recurrence and good long-term survival. Nonspecific extracardiac symptoms, signs, complications, and laboratory findings may be the initial manifestations contributing to misdiagnosis of these rare but totally treatable atrial tumors.

Intracardiac eustachian valve cyst in an adult detected with other cardiac anomalies: usefulness of multidetector CT in diagnosis

We present an unusual case of an intracardiac Eustachian valve cyst observed concurrently with atresia of the coronary sinus ostium, a persistent left superior vena cava (LSVC) and a bicuspid aortic valve. There have been several echocardiographic reports of Eustachian valve cysts; however, there is no report of multidetector computed tomography (MDCT) findings related to a Eustachian valve cyst. Recently, we observed a Eustachian valve cyst diagnosed on MDCT showing a hypodense cyst at the characteristic location of the Eustachian valve (the junction of the right atrium and inferior vena cava). MDCT also demonstrated additional cardiovascular anomalies including atresia of the coronary sinus ostium and a persistent LSVC and bicuspid aortic valve.

Resection of a cardiac tumor extending into the inferior vena cava presenting as Budd-Chiari syndrome

This report describes the successful treatment of a case of cardiac adenocarcinoma with the clinical presentation as Budd-Chiari syndrome. Complete surgical excision of the atriocaval mass was successfully achieved under deep hypothermic circulatory arrest. Histopathological diagnosis of this tumor was tubular adenocarcinoma with positive immunostaining by carcinoembrionic antigen. Subsequent systemic search could not detect any evidence of extra-cardiac primary site and distant metastatic lesion. A 2-year follow-up without any adjuvant therapy revealed no sign of recurrence.

Budd-Chiari syndrome and portal vein thrombosis due to right atrial myxoma

Budd-Chiari syndrome is a rare disorder characterized by hepatic venous outflow obstruction. Atrial myxomas account for 35% to 50% of primary cardiac tumors and are usually located in the left atrium. We describe a patient who presented with hepatic inferior vena cava and portal vein thrombosis due to a large myxoma of the right atrium. After the successful removal of the tumor, ascites resolved completely. We conclude that right atrial myxoma is a rare but potentially curable cause of Budd-Chiari syndrome.

Eustachian valve cyst

Transesophageal echocardiography provides high resolution of intracardiac structures. One potential problem is the misdiagnosis of previously unrecognized benign cardiac structures as malignant processes, leading to unnecessary surgical procedures. We describe an unusual case of benign intracardiac eustachian valve cyst monitored over 2 years.

Traumatic cardiac rupture with acute ascites

A rare accumulation of serous ascites following traumatic cardiac rupture is reported for a 21-year-old man transferred to the emergency center of our hospital from a community hospital suffering from severe shock due to a motorcycle accident. Computed tomography scan showed moderate pericardial and intrapelvic fluid accumulation strongly suggesting cardiac and visceral injuries. An emergency sternotomy disclosed a rupture of the right atrial appendage, successfully closed with primary sutures. A laparotomy was done to aspirate moderate serous fluid, which was clear and not bloody. Edema of the retroperitoneal space and hepatic congestion were noted with no accompanying organ injury. Ascites pathogenesis is unknown but appeared to be related to portal venous congestion induced by cardiac tamponade combined with massive intravenous fluid infusion done to correct the patient's deteriorating hemodynamics.

Myxomatous embolization resulting in unilateral amaurosis

A patient with sudden, painless monocular blindness is an uncommon emergency department presentation. Despite often futile attempts to treat the blindness, most clinicians search for a source of possible embolization. A patient is presented that developed monocular blindness without a clinically apparent source. Advanced diagnostic imaging showed a previously undetected atrial myxoma. The salient clinical features, diagnostic techniques, and therapeutic interventions for this uncommon cardiac tumor are discussed.

Right atrial myxoma originating from the inferior vena cava

A patient undergoing successful excision of a right atrial myxoma arising from the inferior vena cava is reported. The rarity of this case prompted a review of the literature in which only 2 other patients with a right atrial myxoma originating from inferior vena cava tissue were found.
