Subaortic stenosis in a 2.9kg, 3-month-old pug dog and a 11 kg, 4-month-old Rott -weiler dog showing signs of dyspnea, tachypnea, anorexia, exercise intolerance and depression was diagnosed with electrocardiography, thoracic radiography and ultrasonographic evaluation. In electrocardiography, PR interval widening, R wave amplitude increase in lead II in case 2, ST segment depression and left axis deviation in case 1 and 2 were identified. In thoracic radiographs, enlarged left ventricle and atrium, caudal displacement of left crus of diaphragm and caudal part of cranial mediastinum widening were identified in ventrodorsal view. In lateral view, left ventricular enlargement, secondary dorsal deviation of trachea and post-stenotic dilation of aorta were seen. Also, edematous pulmonary changes were shown in peri-hilar area. In ultrasonographic examination, left ventricular dilatation, pericardial effusion and subaortic valvular ridge were seen with real time B-mode in right parasternal long axis view. Aortic valve regurgitation was identified in color-Doppler mode.

This is a report of a case in which a left atrial myxoma was successfully removed by total cardiopulmonary bypass with total hemodilution and moderate hypothermia. The patient was a 17 old girl with mitral valvular symptoms that occured suddenly three months prior to operation. After the onset of symptoms. it was progressively aggravated to serious general condition. The preoperative diagnosis of left atrial tumor was made from echocardiography. and the tumor was confirmed as myxoma by the histopathological examination of the tumor tissue removed during operation. The myxoma was unusually originated from posterior wall of the left atrium. which was located between drainage orifices of right and left pulmonary veins, The tumor developed in the left atrial cavity and one of the polypoid processes of the myxoma was prolapsed into the the left ventricle through the mitral orifice. Following operation. there was no evidence for peripheral vascular embolism, and all valvular symptoms disappeared. The postoperative course was uneventful.

This presents a case of anomalous pulmonary venous drainage from the right lung to the inferior vena cava [scimitar syndrome], which was corrected with an intracardiac approach. Autogenous pericardium was used to create an intracardiac tunnel redirecting flow from the anomalous vein to the left atrium through a surgically enlarged atrial septal defect. The postoperative results have veen satisfactory.

We experienced a case of ruptured aneurysm of the sinus of Valsalva, and this resulted in simultaneous aortic and tricuspid valve endocarditis through a shunt. The echocardiography showed a ruptured sinus of Valsalva aneurysm to the right atrium with a shunt. The aortic non-coronary cusp was fibro-thickened with vegetation. Vegetations of the septal leaflet and the anterior leaflet of the tricuspid valve were also found. The blood culture grew Enterococcus garllinarum. We replaced both tricuspid and aortic valve with successful surgical result.

A 21 year-old male patient had a diagnosis of Budd-Chiari syndrome caused by inferior vena caval obstruction. Conservative medical therapy failed to control the symptoms of both portal hypertension and inferior vena caval stasis. Portocaval or mesocaval shunts may relive the symptoms of chronic forms of Budd-Chiari syndrome. But when inferior vena caval stenosis is severe, another procedure has to be used. Cavoatrial or portoatrial shunt has been suggested. Therefore, a long Dacron graft was placed from the inferior vena cava just below the left renal vein to the right atrium. He exhibited almost complete relief of symptoms for 1.5 year postoperatively. And there was angiographic proof of patency of the graft. This simple procedure should be encouraged in treatment of these patients.

Cardiac myxomas are most common benign tumor and comprise approximately 50% of all primary cardiac neoplasms. They are intracavitary tumors occurring within any of the cardiac chambers, but they have a predilection for the atria and particularly the left atrium. Its are usually arise from the region of the limbus of the fossa ovalis. Clinically, they present with various manifestations due to obstruction to blood flow, embolization, and constitutional changes. Excision with the aid of cardiopulmonary bypass has been established as the treatment of choice for these histologically benign, but potentially malignant tumors and has generally produced good results [17]. We have experienced two cases atrial myxomas, one is left, the other is right and resected under established cardiopulmonary bypass, so we report these cases with the review of the literature.

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 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.

Hepatoblastoma is a hepatic tumor predominantly occurring in children. The usual site of metastasis is the lung. There are only several reports worldwide on the distant metastasis of hepatoblastoma to the central nervous system in children. Only one reported case showed survival of a patient after multiple resections of a recurrent brain lesion. Involvement of the cardiovascular system has been reported in the medical literature. Lesions almost always involve the right-side of the heart. We report a case of recurrent hepatoblastoma at multiple sites, including brain, left atrium of the heart and lung in a 6-year-old girl who was partially treated in the past at the age of 1.5 years; the patient had been event-free for four and a half years.

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.
