Congenital absence of the pericardium is thought to be uncommon. There are two types, complete and partial, of different clinical features. Complete type is innocuous but partial type is potentially fatal due to herniation. This case was referred for an unusual appearance of chest radiograph taken after admissio n for bronchopneumoia without any cardiac symptoms. Plain chest radiograph showed an unusual bulging on the left inferior cardiac boarder. The diagnosis was made on the characteristic findings as a partial defect of right side pencardium in the cardiac gated cinemagnetic resonance imaging study. We presented a case of pericardial defect with brief review of the related literatures.

Epicardial fat may anteriorly produce an echo-free space that can be mistaken for pericardial fluid. We recently experienced a 67-year-old woman with prominent epicardial fat which was presented as an echogenic tumor-like mass. She underwent open pericardiostomy to relieve large amount of pericardial effusion. Operative findings revealed only prominent epicardial fat. Biopsy of the pericardial and fat tissues revealed an inflammation and normal fat cells without any malignant cell infiltration.

Congenital absence of the pericardium is a rare cardiac malformation and is most often asymptomatic. It is usually discovered as an incidental finding. Physical examination, chest radiography, and electrocardiogram are often unremarkable. Echocardiography provides valuable information, and sometimes computed tomography or magnetic resonance imaging is needed for subsequent confirmation.

A thymic cyst in the middle mediastinum adjacent to the right pericardium is extremely rare. We report a case of a large thymic cyst in the right cardiophrenic angle, compressing the right atrium, which was presented as a cardiomegaly on the chest radiograph and a pericardial cyst on the echocardiography. The definitive diagnosis was confirmed using surgical resection and biopsy.

Cardiomegaly is a commonly encountered clinical presentation on simple chest radiographs, and it usually indicates the enlargement of one or more cardiac chambers. However, cardiomegaly less commonly comes from abnormalities in the structures adjacent to the heart, including pericardial effusion, enlarged great vessels, or mediastinal tumors. Pericardial lipoma is a rare primary cardiac tumor that can grow to a large size by the time of diagnosis and result in huge cardiomegaly because of a lack of symptoms. Here, we report a rare case of giant pericardial lipoma that presented as huge cardiomegaly on simple chest radiographs. Multi-modality cardiovascular imaging, including echocardiography and cardiac magnetic resonance imaging, played a key role in the diagnosis and development of a therapeutic treatment plan for the present case.

We report a very rare case of mediastinal tuberculosis in a 57-year old woman who presented with a large mediastinal cyst on chest radiography. She had a 10-year history of exertional dyspnea, but felt comfortable at a rest. A subsequent chest CT suggested a mediastinal cyst with mediastinal lymphadenopathy and communicating pericardial sac. She underwent a thoracotomy and excision of the mass, which was histologically revealed to be of tuberculous origin. Although rare, the apparent increase in the incidence of tuberculosis may result mediastinal cysts being diagnosed mediastinal tuberculosis. We also briefly review mediastinal lymphadenopathy due to tuberculosis.

A 71-yr-old male patient with three vessel coronary artery disease underwent a coronary artery bypass graft. The patient was found to have a large pericardial defect at the apex of the heart that measured approximately 18 cm in circumference. The edge of the pericardial defect impinged on the epicardial coronary arteries. The left phrenic nerve descended via the dorsal boundary of the pericardial defect. Following coronary artery bypass grafting, the pericardial defect was repaired with a polytetrafluorethylene patch. The patient had an uncomplicated postoperative course.

Trousseau's syndrome comsists of migratory thrombophlebitis and thromboembolic disorders of the venous and arterial systems in a malignancy or occult cancer. The overall incidence has been reported to vary from 1 to 11%. Pancreatic, lung, prostate, and stomach cancer is associated with the greatest risk of thromboembolic events. We encountered a 49-year-old man who presented with painful swelling of his lower legs. The chest radiograph showed increased opacity of the Left middle lung fields and Doppler sonography showed a thrombus in the left superficial femoral vein. Chest Computed Tomography showed a 5cm sized left hilar mass invading the pericardium with lymphadenopathy. The bronchoscope biopsy demonstrated an adenocarcinoma of the lung. Platinum based chemotherapy and anticoagulant therapy with warfarin was carried out. The patient was later discharged with an improvement in the painful swelling of his lower legs.

A 76-year-old male underwent a left upper lobectomy with wedge resection of the superior segment of the left lower lobe using video-assisted thoracoscopic surgery (VATS) for non-small-cell lung cancer of the left upper lobe. He presented with shortness of breath, fever, and leukocytosis. Chest radiography showed atelectasis at the remaining left lower lobe. Bronchoscopy revealed narrowing of the left lower bronchus with purulent secretion, and computed tomography showed downward kinking of the left lower lobar bronchus. He underwent exploratory VATS, and intraoperative findings showed an inferiorly kinked left lower lobar bronchus with upward displacement of the left lower lobe. After adhesiolysis, the kinked bronchus was straightened, and bronchopexy was performed to the pericardium to prevent the recurrence of bronchial kinking. Also, the inferior pulmonary ligament was reattached to prevent upward displacement. Postoperative follow-up bronchoscopy revealed no evidence of residual bronchial obstruction, and chest radiography showed no atelectasis thereafter.

BACKGROUND: A preclinical study was conducted for evaluating a valved conduit manufactured with a glutaraldehyde (GA)-fixed bovine pericardium treated using an anticalcification protocol. METHODS: Bovine pericardia were decellularized, fixed with GA in an organic solvent, and detoxified. We prepared a valved conduit using these bovine pericardia and a specially designed mold. The valved conduit was placed under in vitro circulation by using a mock circulation model, and the durability under mechanical stress was evaluated for 2 months. The valved conduit was implanted into the right ventricular outflow tract of a goat, and the hemodynamic, radiologic, histopathologic, and biochemical results were obtained for 6 months after the implantation. RESULTS: The in vitro mock circulation demonstrated that valve motion was good and that the valved conduit had good gross and microscopic findings. The evaluation of echocardiography and cardiac catheterization demonstrated the good hemodynamic status and function of the pulmonary xenograft valve 6 months after the implantation. According to specimen radiography and a histopathologic examination, the durability of the xenografts was well preserved without calcification at 6 months after the implantation. The calcium and inorganic phosphorus concentrations of the explanted xenografts were low at 6 months after the implantation. CONCLUSION: This study demonstrated that our synergistic employment of multiple anticalcification therapies has promising safety and efficacy in the future clinical study.
