The papers presented at the Fifth International Symposium on Heart Valves and published in this volume discuss clinical experience with heart valve replacement in pediatric patients, in adults (age 65 and younger), and in the elderly (age 66 and older). Special considerations in heart valve replacement, such as valve selection, reoperation, results of double valve implantation, quality of life, and the use of valved conduits are also included. Finally, longยญ term clinical follow-up with the ST. JUDE MEDICALยฎ heart valve, giving 7- and 8-year data is discussed. HEART VALVE REPLACEMENT IN PEDIATRIC PATIENTS Anticoagulation Anticoagulation in children is a difficult and interesting problem. Three princiยญ pal considerations in the use of anticoagulants are patient education, timing, and anticoagulating substance. Additional considerations are patient tolerance and compliance. Generally, the findings indicate, if pediatric patients receive anticoagulation following mechanical valve replacement, it is well accepted and results in few complications. If children are not anticoagulated, complications arise. Conflicting results regarding the efficacy of PERSANTINEยฎ and the use of aspirin vs. COUMADINยฎ were reported. Doctor Sade's data address some of these questions. * After a 5-year study in * See J Thorac Cardiovasc Surgery 1988; 95:533-561
