We report a case of a 40-year-old woman whose right ventricular out-flow tract was moderately obstructed by a heavily calcified pericardial ring. It was passing over the base of pulmonary artery and mid-portion of left ventricle but the other parts of the pericardium was mildly fibrotic. The pericardium and calcified ring were completely removed under cardiopulmonary bypass. The patient was recovered uneventfully and we could not find the specific cause of calcified pericardial ring.

We experienced primary repair of complete atrioventricular septal defect with Teralogy of Fallot. The diagnosis was established preoperatively by echocardiography, cardiac catheterization and cardioangiography. Repair was accomplished using cardiopulmonary bypass. Two patch techinque were performed using Dacron patch for ventricular septal defect and pericardial patch for atrial septal defect. Infundibullectomy and right ventricular outflow tract reconstruction with the transannular pericardial patch were performed. The postoperative echocardiography showed mild mitral and tricuspid regurgitation, but there were no hemodynamic abnormalities.

We report a case of a resection of very large intracavitary metastatic malanoma causing obstruction of the right ventricular inflow and outflow tract of the heart. A 49-year-old woman with dyspnea and generalized edema was seen. Echocardiography reveal an intra cavitary mass occupying the entire right ventricle and pericardial effusion. The lesion was palliatively resected using a cardiopulmonary bypass and was confirmed as a malignant melanoma. The patient is alive and improved symptomatically 30days after the operation.

Primary tumors of the heart are extremely rare, and about 25 per cent of primary cardiac tumors are malignant. Recently, We experienced a case of primary cardiac liposarcoma occurred on the right ventricular outflow tract and extended into the main pulmonary artery. The patient was 57 year-old man and the chief complaints was severe exertional dyspnea. Emergency operation to relieve the right ventricular outflow tract obstruction was performed under cardiopulmonary bypass. The tumor was 5$\times$4$\times$3 cm in size and infiltrated into the right ventricle and ventricular septum. The tumor in the main pulmonary artery was removed without any difficulty but the on the right ventricular outflow tract was difficult to remove completely. The patient was recovered without any specific problems. After successful surgical resection and postoperative radiotherapy the patient discharged with good condition. Herein, the clinical characteristics of cardiac liposarcoma, the problems in differential diagnosis, the prognosis and current therapy are reviewed.

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.

Pulmonary tumor embolism can be a cause of respiratory failure in patients with cancer even though it occurs rarely. We describe a 56-year-old man who underwent a pulmonary tumor embolectomy using cardiopulmonary bypass on beating heart combined with inferior vena cava embolectomy and right radical nephrectomy. Aggressive surgical treatment in this severe case is necessary not only to reduce the fatal outcome of pulmonary embolism in the short run, but also to improve the oncological prognosis in the long term.

The formation of aortic thrombi is an extremely rare complication of acute pancreatitis. Here we report a case of acute pancreatitis complicated by a paraesophageal pseudocyst, necrotizing mediastinitis, and the formation of multiple thrombi in the ascending aorta. The patient was successfully treated by surgical therapy, which included extensive debridement of the mediastinum and removal of the aortic thrombi under cardiopulmonary bypass. Although esophageal resection was not carried out concomitantly, the lesions were resolved and the patient remained free of complications over 2 years of follow-up care.

Coronary spasm generally occurs in patients with minimal atherosclerotic plaque lesion, and it has a rather favorable prognosis. However, in some cases, coronary spasm may induce myocardial infarction and even sudden cardiac death (SCD). Here, we report a case in which multi-vessel intractable coronary vasospasm suddenly occurred in a diffuse atherosclerotic lesion after percutaneous coronary intervention (PCI) in a patient with aborted SCD. We identified the characteristics of the spasm portion in intravascular ultrasound (IVUS) images and conducted percutaneous cardiopulmonary bypass support-PCI with stenting as treatment. Intima and media thickening and a large attenuated plaque burden with rupture were identified in IVUS images at the obstructive spasm portion.

Traumatic pulmonary artery rupture is a rare, life-threatening injury. Currently, no strict guidelines for its management exist. Herein, we report a successful surgical repair of a right pulmonary artery rupture caused by being stepped on.

A 55-year-old man underwent emergent sternotomy due to cardiac tamponade occurring just after an accidental fall from a 10-m height. Tricuspid valve regurgitation was found on echocardiography while he was on mechanical ventilation after the operation. The patient was weaned successfully from mechanical ventilation after tricuspid valve repair under cardiopulmonary bypass. Traumatic tricuspid valve regurgitation is a rare blunt chest injury and its symptoms occur late. Tricuspid regurgitation should be considered as a reason for failure to wean from mechanical ventilation after blunt cardiac trauma.
