Between February 1982 and January 1984 27 St. Jude Medical cardiac valve prostheses were implanted in 24 children ranging in age from 5 to 20 years (mean 12.38 years). There were 10 isolated aortic valve replacements, 14 isolated mitral valve replacements and one triple valve replacement (aortic, mitral and tricuspid). There was one operative and four late deaths. All patients were maintained on Aspirin and Dipyridamole from the early postoperative period. There were six documented thromboembolic events occurring in five patients. There were 0.68 thromboembolic events per patient year in the aortic valve group and 0.19 events in the mitral valve group. Because of the significant incidence of thromboembolic events in our patients, we now recommend universal anticoagulation with Coumadin in all pediatric age patients in whom the St. Jude Medical prosthesis is implanted.

Traumatic blunt thoracic aortic injury is a clinical entity of increasing incidence. After the diagnosis of traumatic tear of the aorta is made, there is some controversy over whether the aorta should be repaired using cardiopulmonary bypass, a heparinized shunt, or cross-clamping and graft interposition without a shunt or bypass. At Allegheny General Hospital, 19 patients were treated for traumatic tears of the thoracic aorta between July 1, 1977, and June 30, 1983. They can be divided into two groups: Group 1 (July 1, 1977, through October 31, 1981), in which no shunt or bypass or only a heparinized shunt was used, and Group 2 (November 1, 1981, through June 30, 1983), in which left atrium-femoral artery bypass was performed using a BioMedicus heparinless pump and tubing. Among the 10 patients in Group 1, 4 died and 2 had paraplegia postoperatively. Among the 9 patients in Group 2, 1 died and none experienced paraplegia following operation. We believe that the BioMedicus centrifugal pump is a simple, safe means of perfusing the lower body, kidneys, and spinal column without necessitating heparinization in a patient with multiple injuries or the placement of a cumbersome heparinized shunt. Because of the simplicity and the reliability demonstrated, this pump should be considered for use in all patients with traumatic tears of the thoracic aorta.
