Recent progress in cardiovascular surgery has promoted less non-invasive surgery. We reoperated in a forty-two year old female for aortic valve regurgitation using the J-sternotomy approach and experienced good results. The patient was operated on with AVR 12 years after her first cardiac operation. ⋯ A conventional Two-stage cannula was placed in the auricle of the right atrium. A venting tube was also cannulated through the right upper pulmonary vein. J-sternotomy and minimal adhesionectomy made for a good operative field to establish cardiopulmonary bypass and to perform aortic valve re-operation.

We evaluated right and left ventricular function by intraoperative transesophageal echocardiography for the patients with left ventricular dysfunction (left ventricular ejection fraction (LVEF) < or = 40) who underwent isolated coronary artery bypass grafting (CABG). We divided these patients into two groups; group 1 who had difficulty of weaning from cardiopulmonary bypass due to hypotension (n = 8) and group 2 who did not have any difficulty of it (n = 17). Basement characteristics (age, gender, history of myocardial infarction, congestive heart failure, LVEF, severity of the right coronary artery disease) of both groups were not different significantly. ⋯ On the other hand, right ventricular systolic function was severely impaired, particularly postoperatively, in group 1 compared with group 2. Right and left ventricular systolic function of group 2 was fairly improved postoperatively. These results may indicate that right ventricular dysfunction is a potent predictor of postoperative morbidity and mortality for the patients with left ventricular dysfunction who undergo isolated CABG.

Review Case Reports
[Video assisted thoracic surgery for the treatment of catamenial pneumothorax].
Video assisted thoracic surgery (VATS) was applied in 3 cases of pneumothorax combined with pathologic changes in the diaphragm (two cases of catamenial pneumothorax and one case of suspected catamenial pneumothorax). Case 1, 39-year-old woman, was preoperatively diagnosed as catamenial pneumothorax in the right lung. Thoracoscope was inserted through the 5th intercostal anterior axillary line and the lesion with the pathologic changes in the central tendon of the diaphragm was incised and sutured with Endo-GIA and Endo-STAPELAR. ⋯ VATS can fully be carried out for pathologic changes in the diaphragm in catamenial pneumothorax. Since catamenial pneumothorax may be complicated with another pathologic changes in the diaphragm (Case 1) or in the visceral pleura (Case 3), the whole thoracic cavity, including diaphragm and visceral pleura, should be carefully observed under thoracoscopy. Application of minithoracotomy-associated thoracoscopic surgery is a useful method in the case to whom catamenial pneumothorax is definite or suspected.

We report our experience of the treatment of a 60-year-old man with upper tracheal fistula which developed on the 11th day after radical surgery for esophageal cancer. Primary treatment to close the fistula was unsuccessful, resulting in the involvement of empyema due to infection. Controlled ventilation with T-tube and drainage through a chest tube for 2 months lead to depuration of the thoracic cavity. ⋯ The patient's overall condition improved thereafter and closure was being considered. However, the patient died on the 116th day postoperatively due to supervenient aspiration pneumonia. Thus, long-term controlled ventilation with a T-tube was beneficial for the treatment of central airway injury.

Between November 1992 and February 1996, 84 patients (less than 3 months of age) underwent open heart surgery. Among 76 patients except 8 who required mechanical circulatory support, the sternum was left open. The indication of open sternotomy was hypoplastic left heart syndrome in 14 patients and unstable hemodynamics in 4 patients. ⋯ By the time of sternal closure, blood pressure, left atrial pressure and respiratory parameters improved and inotropics were reduced with the minus fluid balance. One patient died of sepsis 4 days after delayed sternal closure. Delayed sternal closure was effective modality to neonates or early infants after complex open heart surgery.
