Although the last decade has brought dramatic improvement in patient selection and postoperative management of adults and children undergoing advanced mechanical circulatory support, technological advances have been largely limited to the adult population. Intraaortic balloon pumps are technically feasible, but their efficacy has been questioned and their use has been limited in children. Over the last decade, extracorporeal membrane oxygenation has become the most commonly used method of mechanical circulatory support in children who have severe cardiac failure after cardiac operations. ⋯ Surprisingly, many of these patients did well with left ventricular support only. The overall children's survival rates in the myocardial recovery group are better than those in adults. However, current pediatric devices do not provide support for greater than a few weeks, making bridging to transplantation less feasible than in adults.

Review Case Reports
Retrograde coronary sinus cardioplegia in the presence of persistent left superior vena cava.
Administration of retrograde cardioplegia is hampered by the presence of a persistent left superior vena cava, which results in excessive runoff of solution into the persistent left superior vena cava and the right atrium. Technical modifications are described that permitted aortic valve replacement to be performed in a patient with persistent left superior vena cava using only retrograde cardioplegia.

Seven of 119 patients undergoing anatomical correction for transposition of the great arteries and Taussig-Bing anomalies without pulmonary stenosis had the Damus-Stansel-Kaye procedure and the rest, the arterial switch. The age of the patients having the Damus-Stansel-Kaye procedure ranged from 0.5 year to 5 years (mean age, 2.2 +/- 1 years). Four patients had transposition, 2 had Taussig-Bing anomaly, and 1 had corrected transposition. ⋯ The only patient who did not have transection of the main pulmonary artery, an omission that led to an obstructed conduit at the distal anastomosis, died late. Two patients subsequently needed aortic outflow closure for critical aortic insufficiency. The Damus-Stansel-Kaye procedure has a definite role and can be safely performed in patients with transposition of the great arteries and Taussig-Bing anomalies.(ABSTRACT TRUNCATED AT 250 WORDS)

One of the dilemmas in the management of lung allotransplant recipients is our inability to precisely determine the cause of graft dysfunction. Differentiating between lung allograft infection, rejection, atelectasis, or ischemic injury remains a difficult task. ⋯ Transbronchial biopsy and bronchoalveolar lavage have emerged as two methods with the most potential for aiding in the establishment of diagnosis. This review attempts to provide the readers with a current knowledge of the cellular events in lung allograft and the status of bronchoalveolar lavage in experimental and clinical lung transplantation.

A 71-year-old man with a postoperative aortobronchial fistula was successfully treated. The fistula occurred between the left lower lobe and the descending thoracic aorta, to which a distal anastomosis of a temporary bypass graft had been placed during thoracic aortic aneurysmectomy 3 years before. For saving patients with this complication, early surgical treatment during episodes of intermittent hemoptysis is important. The use of an omentum pedicle flap for the isolation of the suture line is a important adjunct.
