Venous return for cardiopulmonary bypass is successfully achieved using of two stage cavoatrial cannula. Right heart decompression is facilitated and drainage optimized by the use of a caval occluding clamp which stabilizes the cannula. This technique is described.
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.
Inadvertent tears to the atrial caval junction during open heart surgery can present as a disastrous complication. A method is described by which a flap of pericardium is mobilized and sutured over the caval laceration. Control of bleeding is facilitated and caval obstruction is minimized.
