Heparin bonding of the cardiopulmonary bypass (CPB) pump circuit decreases complement activation and fibrinolysis. It is not known whether inflammatory cytokines produced during CPB can also be modulated by the more biocompatible heparin-coated circuit. ⋯ These data indicate that the use of heparin-coated bypass pump circuits results in lower serum levels of the inflammatory cytokines IL-6 and IL-8 than standard circuits. Biocompatible materials that decrease the inflammatory response to CPB may ultimately reduce the morbidity associated with cardiac operations.

Fungal prosthetic valve endocarditis is an uncommon but serious disease. We have developed a strategy of treatment that includes perioperative amphotericin B, radical debridement of infected tissue, reconstruction using biologic tissue when possible, and prolonged oral suppressive antifungal therapy. ⋯ We conclude that preoperative treatment with amphotericin B, radical resection of all infected tissue, cardiac reconstruction using biologic tissue when possible, and life-long oral antifungal therapy is effective for fungal prosthetic valve endocarditis.

Between 1983 and 1994, 115 infants and children underwent repair of a complete atrioventricular canal defect with the two-patch technique and routine mitral valve "cleft" closure. ⋯ For infants with complete atrioventricular canal defect, repair using the two-patch technique with routine mitral valve cleft closure at 4 to 6 months of age results in a low operative mortality, a low incidence of permanent heart block, and a low reoperation rate for mitral insufficiency.

Junctional ectopic tachycardia is an early postoperative complication after intracardiac repair of congenital heart disease, especially in infants. Because of the high ventricular rate and the usually poor response to antiarrhythmic drugs, this condition is associated with a high morbidity and mortality. The purpose of this study was to assess the safety and efficacy of moderate body surface hypothermia in the treatment of postoperative junctional ectopic tachycardia in infants. ⋯ Early institution of moderate hypothermia by body surface cooling was a safe and efficient measure to control ventricular rate in infants with postoperative junctional ectopic tachycardia.

This report describes the conditions and results of coronary-coronary bypass using the radial artery on the right coronary artery. The angiographic and clinical results are excellent.
