Cardiac surgery in a girl with trisomy 13

Pediatric sub-specialist controversies in the treatment of congenital heart disease in trisomy 13 or 18

Trisomy 13 and 18 are associated with congenital heart disease. Cardiac palliation has been reported in the literature, but is not usually done in this population. Thus, a multi-disciplinary team may experience controversy in formulating a care plan that includes cardiac intervention. Our objective was to determine differences in recommendations for cardiac intervention in this population between physicians specializing in pediatric cardiac critical care, neonatology, and genetics. A web-based survey was performed between April 2007 and August 2008. This survey evaluated surgical and transcatheter cardiac palliations that had been performed for individuals with trisomy 13 or 18 at the respondent's institution, the respondent's recommendations for cardiac intervention in hypothetical symptomatic patients with trisomy 13 or trisomy 18 and the influence of parental preference on these recommendations. Eight hundred fifty-nine responses were obtained from a primarily academic practice setting (59%). Cardiologists were most likely to recommend intervention; low risk interventions were recommended by 32% of cardiologists, 7% of neonatologists and 20% of geneticists. Parental request to intervene resulted in a 3 fold increased in the likelihood of all specialist recommending intervention. Counseling of families frequently occurred by multiple sub specialists (50%) and there was frequently (71%) a difference in opinion. Individuals with trisomy 13 or 18 are receiving cardiac intervention at many institutions. Cardiologists were more likely than geneticists or neonatologists to recommend intervention on all heart lesions other than single ventricle palliation which no specialists recommended. Parental wishes that "everything be done" significantly influenced all specialists' recommendations.

Intensive cardiac management in patients with trisomy 13 or trisomy 18

Intensive cardiac management such as pharmacological intervention for ductal patency (indomethacin and/or mefenamic acid for closure and prostaglandin E1 for maintenance) and palliative or corrective surgery is a standard treatment for congenital heart defects. However, whether it would be a treatment option for children with trisomy 13 or trisomy 18 syndrome is controversial because the efficacy on survival in patients with these trisomies has not been evaluated. We retrospectively reviewed 31 consecutive neonates with trisomy 13 or trisomy 18 admitted to our neonatal ward within 6 hr of birth between 2000 and 2005. The institutional management policies differed during three distinct periods. In the first period, both pharmacological ductal intervention and cardiac surgery were withheld. In the second, pharmacological ductal intervention was offered as an option, but cardiac surgery was withheld. Both strategies were available during the third period. The median survival times of 13, 9, and 9 neonates from the first, second, and third periods were 7, 24, and 243 days, respectively. Univariate and multivariate analyses confirmed that the patients in the third period survived significantly longer than the others. Intensive cardiac management consisting of pharmacological intervention for ductal patency and cardiac surgery was demonstrated to improve survival in patients with trisomy 13 or trisomy 18 in this series. Therefore, we suggest that this approach is a treatment option for cardiac lesions associated with these trisomies. These data are helpful for clinicians and families to consider in the optimal treatment of patients with these trisomies.

Effectiveness of cardiac surgery in trisomies 13 and 18 (from the Pediatric Cardiac Care Consortium)

Because of severely reduced lifespan in children with trisomies 13 and 18, surgical repair of congenital heart lesions has rarely been offered. With data from a multicenter registry, we report 35 cases of cardiac surgery in infants and children with trisomy 13 or 18 with a 91% hospital survival rate. Those patients without an extended preoperative ventilatory requirement did not require prolonged mechanical ventilation after surgery.
