Abstract

RationaleAspirin resistance has been reported in up to 80% of children with cardiovascular defects undergoing surgery. Because of a patient who had embolic stroke while on therapeutic aspirin dose but in whom aspirin resistance was present on his thromboelastography platelet mapping, we chose to obtain thromboelastography platelet mapping on cardiac patients on aspirin to assess their risk.ObjectivesThis study evaluates aspirin resistance noted in these patients and their characteristics.Methods and resultsThis is a retrospective study of 25 patients taking aspirin for a month at therapeutic dose. In total, 11 female patients were enrolled. Ages in all subjects were 5 months to 27 years. A total of 19 patients had a Fontan surgery. Three had a cavopulomanary anastomosis, one had a hybrid procedure, and two had coronary anomalies. Compliance was assessed at the time of the clinic visit. Aspirin resistance was defined as platelet inhibition below 50%. Variables evaluated were level of platelet inhibition, age, body mass index, and gender.
