A 75-year-old man was admitted to the hospital because of a pericardial effusion.After 3 L of blood-stained pericardial fluid was drained, clinical examination together with echocardiography and chest computed tomography showed a tumor in the right atrium. At operation a pedunculated vascular tumor was found with a broad base which was embedded in the atrial wall and extended into the pericardium.A wide resection was performed resulting in a large defect of the right atrial wall. The defect was reconstructed with a pericardial patch. The patient did well postoperatively, but bloody pleural effusion developed later, presumably because of pulmonary metastasis. The patient died 2 months after surgery as a result of respiratory failure.

Cor triatriatum is a rare congenital heart disease that is often lethal in children if not correctly identified and properly managed, Characteristically an anomalous membrane divides the left atrium into two chambers one located posterosuperiorly which is connected to the common pulmonary venous trunk and the other anteroinferiorly which is connected to the left atrial appendage and the mitral valve. Eight patients with Cor triatriatum were been seen at our hospital from 1984 to 1999. The clinical presentation diagnostic evaluation and surgical results are outlined in this retrospective review. Resection of the obstructing anomalous atrial membrane was performed using a hypothermic cardiopulmonary bypass in all cases. Right atriotomy was performed in all patients and left atriotomy was performed in a patient who had poor preoperative general conditions and serious cardiac defects(TAPVR & hypoplastic left ventricle) died of low cardiac output during the immediate postoperative period. The postoperative course has been excellent in the remaining. Cor triatriatum is amenable to surgical repair with excellent results when diagnosed early and in those who are not complicated by other complex cardiac anomalies.

We report the case of a 69-year-old woman who was diagnosed with intracardiac schwannoma without symptoms. Preoperative echocardiography and cardiac magnetic resonance imaging showed a mass attached to the interatrial septum. The initial diagnosis was a myxoma or a bronchogenic cyst. The tumor was successfully excised under cardiopulmonary bypass. However, the pathology of the excised tumor was consistent with schwannoma. We suggest that cardiovascular surgeons consider schwannoma to be a possible differential diagnosis for a mass close to the interatrial septum.

A castrated, 6-year-old, male Turkish Angora cat with a history of respiratory distress was referred to the hospital. Physical examination revealed a cardiac murmur, and thoracic radiographic findings revealed pleural effusion and cardiomegaly. Echocardiography showed abnormality of the tricuspid and mitral valve, and color-flow Doppler imaging revealed regurgitation between both atrium and ventricle. Based on the echocardiographic examination, tricuspid valve dysplasia concurrent with mitral valve dysplasia was diagnosed. However, the patient died a week after treatment. In necropsy, bilateral atrioventricular valve dysplasia and left ventricular hypertrophy were confirmed. This is the first report to describe a middle age Turkish angora cat having bilateral atrioventricular valve dysplasia which has high mortality and only been reported rarely in cats. This case report also describes its clinical signs, diagnostic imaging findings, treatment and discussions how the patient could live long.

We present a patient with a primitive neuroectodermal tumor arising from the right atrium who experienced multiple syncope episodes daily, which had first appeared 1 month after surgery. The symptoms continued to worsen over the course of chemotherapy, and the autonomic function test (AFT) was performed after the 14th chemotherapy cycle. The AFT revealed orthostatic hypotension and reduced baroreflex-dependent sympathetic reactivity. Physical counterpressure techniques were applied with a visual biofeedback intervention, and were found to be effective in reducing the syncope episodes.

Thymomas are common anterior mediastinal tumors with a relatively favorable prognosis compared to that of other types of thoracic malignancies. However, thymomas that invade surrounding structures, such as the heart or vena cava, have been infrequently reported, and intracardiac thymomas are exceedingly rare. Treatment of invasive thymoma is difficult because the high rate of incomplete resection results in a high rate of recurrence. Herein, we present a rare case of a thymoma that originated in the right atrium and extended into the superior vena cava and brachiocephalic vein.

Myxomas are the most common form of intracardiac tumors and are found primarily in the left atrium. In rare cases, Carney and associates have described a syndrome called "the complex of myxoma" consisting of cardiac myxoma, which characteristically is familial, in assocation with two or more of the follow conditions: myxomatous masses (cardiac myxoma, cutaneous myxosma, and mammary myxoid fibroademoma), spotty pigmented lesions of the skin, and endocrine disorders. We report a case of familial atrial myxoma with Carney's complex in a 19-year old woman who has spotty pigmentations on her face, and left atrial myxomas, and myxoma on the right nipple. Her mother and sister share the left atrial myxoma. The myxomas originated in the septum of the left atrium and the anterior leaflet of the mitral valve were successfully excised. In conclusion, family members of affected patients should be screened periodically with echocardiography in an attempt to identify asymptomatic cardiac myxomas. Complete excision and postoperative follow up are necessary to rule out the muticentricity and high rate of recurrent lesions.

A 33-year-old man presented to the physician with epigastric discomfort. Computed tomography of the chest and echocardiography showed a mass in the left atrium; this mass was resected and diagnosed as myxoma. 12 months later, myxoma recurred in the right atrium, and it was resected without recurrence for 10 months until now. As there are only a few reports on recurred right atrial myxoma after left atrial myxoma, we report here on successful surgical removal of a recurred right atrial myxoma after resection of left atrial myxoma.

Cardiogenic embolic stroke accounts for approximately 20% of ischemic strokes and the likelihood of its recurrence is high. Paradoxical embolism may be an important cause of cardioembolic stroke, which can be evaluated through multiple diagnostic modalities including transesophageal echocardiography (TTE) or transcranial Doppler. A persistent left superior vena cava (PLSVC) is a rare congenital vascular anomaly, which mainly drains to the right atrium via the coronary sinus. Although rare, PLSVC draining into the left heart predisposes the patient to paradoxical embolism through a right-to-left shunt. We report on a 78-year-old female patient with an ischemic stroke associated with PLSVC draining into the left atrium through the pulmonary vein, which was investigated via TTE with an agitated saline test and computed tomography.

Ten percent of all myxomas are the familial form. Familial myxomas appear to have autosomal dominant transmission. We experienced two siblings with familial myxomas. A left atrial myxoma was surgically removed in a 21-year-old woman. Six years later, other myxomas were found in the right atrium and the left atrium and these were also surgically removed. Right ventricular and right atrial myxomas were surgically excised in her brother. The two siblings were found to have frame-shift mutations in the PRKAR1A gene (c.537delA; p.Gly180GlufsX26), which is the causative gene for Carney complex. Obtaining the genetic diagnosis makes it possible to prepare more effective therapeutic strategies for these patients and the gene carriers. Complete excision, ruling out multicentricity and proper postoperative follow up are all necessary to avoid recurrence of myxoma.
