Variability in clinical decision‐making for ventricular assist device implantation in pediatrics

BACKGROUND Minimal data exist on clinical decision-making in VAD implantation in pediatrics. This study aims to identify areas of consensus/variability among pediatric VAD physicians in determining eligibility and factors that guide decision-making. METHODS An 88-item survey with clinical vignettes was sent to 132 pediatric HT cardiologists and surgeons at 37 centers. Summary statistics are presented for the variables assessed. RESULTS Total respondents were 65 (72% cardiologists, 28% surgeons) whose centers implanted 1-5 (34%), 6-10 (40%), or >10 (26%) VADs in the past year. Consensus varied by patients' age, diagnosis, and Pedimacs profile. Highest agreement to offer VAD (97%) was a mechanically ventilated teenager with dilated cardiomyopathy. Patients stable on inotropes were less likely offered VAD (11%-25%). SV infant with Pedimacs profile 2 had the most varied responses: 37% offered VAD; estimated survival ranged from 15% to 90%. Variables considered for VAD eligibility included mild developmental delays (100% offered VAD), moderate-severe behavioral concerns (46%), cancer in remission >2 years (100%), active malignancy with good prognosis (68%) or uncertain prognosis (36%), and BMI >35 (74%) or
