Resection of left ventricular tumor using videocardioscopy and echocardiography.

Assessment of large cardiac tumors requires careful definition of the extent, cell type, and degree of invasiveness to determine the best operative management. Preoperative magnetic resonance imaging and echocardiography were helpful, but limited in the assessment and management in the case of a 19-year-old pregnant woman with a large (9 x 5.5-cm) left ventricular mass. Intraoperative echocardiography and videocardioscopy facilitated precise operative decisions and management. Successful resection was achieved without the need for cardiac transplantation. This case demonstrates the complexity of the diagnosis and management of large cardiac tumors.

Squamous cell carcinoma of the lung: an unusual metastasis to pectoralis muscle.

A 44-year-old man with clinical T2 N0 M0 squamous cell carcinoma of the lung presented 4 weeks after left pneumonectomy with a single metastasis to his right pectoralis major muscle. Three years after excision and chemotherapy he remains in remission. Muscle metastasis of carcinoma is an infrequent occurrence. Further investigation into the incidence and treatment is warranted.

Legionella pericarditis diagnosed by direct fluorescent antibody staining.

Legionella pericarditis is a rare and serious manifestation of Legionnaire's disease. A case is presented in which the diagnosis was established by direct fluorescent antibody staining on a pericardial tissue specimen. Video-assisted thoracoscopy was used safely and effectively in diagnosis and management in this case.

Thoracoscopic lung biopsy.

Progress in instrumentation and techniques developed for laparoscopic surgery have paved the way for a resurgent interest in thoracoscopic procedures. Traditional thoracoscopy was limited by access, restricted visualization, and surgical devices. Recent cases provided an opportunity to successfully perform thoracoscopic pulmonary wedge excisions using state-of-the-art technology and instruments adapted from laparoscopy. These preliminary cases provided an opportunity to modify and adapt these techniques to thoracic procedures. Video thoracoscopy is rapidly evolving in both methods and instrumentation.

Blunt traumatic rupture of pulmonary vein, left atrium, and bronchus.

A 22-year-old man fell 12.2 m (40 ft), injuring the right lower lobe bronchus, right inferior pulmonary vein, and left atrium. These injuries were not associated with fractures, cardiac tamponade, or pneumothorax. The severity of injury became apparent only upon right thoracotomy for persistent hemorrhage. This case presented special diagnostic and surgical challenges and suggests a role for the increased use of bronchoscopy in major blunt chest trauma.
