Review Comparative Study
Pericardial effusion: subxiphoid pericardiostomy versus percutaneous catheter drainage.
Optimal management of cardiac tamponade resulting from pericardial effusion remains controversial. ⋯ Benign and malignant pericardial tamponade can be safely and effectively managed with subxiphoid pericardiostomy. Percutaneous catheter drainage should be reserved for patients with hemodynamic instability.

Comparative Study
Comparison of long-term clinical results of double versus single internal mammary artery bypass grafting.
The long-term benefits of double versus single internal mammary artery (IMA) coronary bypass grafting have not yet been established. ⋯ Use of an IMA graft on the left anterior descending coronary artery improves survival compared with use of an SVG. Although patients with double IMA grafts had a greater number of poor prognosis risk factors before operation, their 10-year survival rate was similar to that of patients with a single IMA graft.

A 34-year-old man had development of an aortobronchial fistula 17 years after patch aortoplasty for correction of aortic coarctation and 5 years after blunt chest trauma, an unusual combination of predisposing factors. The clinical presentation, characterized by dysphonia and recurrent hemoptysis, and the surgical findings suggested the posttraumatic origin of the fistula, which was successfully managed by aortic resection and graft interposition under simple aortic cross-clamping, associated with partial pulmonary lobectomy. When hemoptysis occurs in a patient with a history of an aortic thoracic procedure, the presence of an aortobronchial fistula should be suspected. Early diagnosis offers the only possibility of recovery through a lifesaving surgical procedure.

Case Reports
Damus-Kaye-Stansel connections in children with previously transected pulmonary arteries.
In patients with a univentricular arteriovenous connection, transection of the main pulmonary artery may be performed as part of a bidirectional cavopulmonary shunt or Fontan procedure. The proximal stump of the pulmonary artery may remain in the systemic circulation. In cases with a discordant ventriculoarterial connection, subsequent restriction of the bulboventricular foramen may lead to subaortic stenosis. The subaortic stenosis can be corrected in some patients by directing the systemic flow through a combined nonobstructed aortopulmonary outlet, as in the Damus-Kaye-Stansel connection. Previous closure of the pulmonary artery has been considered by some investigators to be a relative contraindication to the Damus-Kaye-Stansel procedure, unless an allograft root can be added to the circuit after excision of the closed pulmonary stump. ⋯ If transection and closure of the pulmonary artery as part of a previous palliation has spared the pulmonary valve, then the native pulmonary outlet might be used for a safe Damus-Kaye-Stansel connection.

The incidence of mediastinitis after cardiac surgical intervention is reported to be between 0.15% and 5% and is a major cause of postoperative morbidity. A number of risk factors have been identified, most of which are not modifiable. It is our contention that this complication can be reduced to a minimum by the consistent application of good operative technique and postoperative management. ⋯ In a large patient series we found a low incidence of mediastinitis (0.25%) and an even lower incidence of required reoperation (0.19%). Except for the use of bone wax and the use of bilateral mammary arteries in diabetic patients, none of the previously identified risk factors are modifiable. We believe that with strict adherence to perioperative aseptic technique, attention to hemostasis, and precise sternal closure, a very low incidence of mediastinitis can be achieved.
