RESUMO
Supravalvular aortic stenosis (SVAS) has been well described in Williams-Beuren Syndrome and non-syndromic elastin (ELN) mutations. Non-syndromic ELN mutations are inherited in an autosomal dominant pattern with incomplete penetrance and variable expressivity. ELN haploinsufficiency leads to progressive arteriopathy, typically affecting the aortic sinotubular junction. Multi-level pulmonary stenosis has also been reported and biventricular obstruction may portend a worse prognosis. Fetal presentation of ELN mutation with SVAS has not been previously reported in the literature. We present a case of fetal diagnosis of SVAS and multi-level pulmonary stenosis in a family with a known pathogenic ELN mutation (Exon 6, c.278del [p.Pro93Leufs*29]). On the fetus' initial fetal echo, there was only mild flow acceleration through the aortic outflow tract, however, she went on to develop progressive bilateral obstruction. In the early post-natal period, the child was clinically asymptomatic and showed similar mild SVAS and mild valvar and supravalvular pulmonary stenosis. Our case highlights the need for serial monitoring of fetuses with suspected or confirmed ELN arteriopathy.

Introduction: Patient transfers pose a potential risk during hospitalizations. Structured communication practices are necessary to ensure effective handoffs, but occur amidst competing priorities and constraints. We sought to design and implement a multidisciplinary process to enhance communication between pediatric cardiovascular intensive care unit and cardiology floor teams with a comprehensive approach evaluating efficiency, safety, and culture. Methods: We conducted a prospective quality improvement study to enact a bed-availability triggered bedside handoff process. The primary aim was to reduce the time between handoff and unit transfer. Secondary metrics captured the impact on safety (reported safety events, overnight transfers, bounce backs, and I-PASS utilization), efficiency (transfer latency, unnecessary patient handoffs, and cumulative time providers were engaged in handoffs), and culture (team members perceptions of satisfaction, collaboration, and handoff efficiency via survey data). Results: Eighty-two preimplementation surveys, 26 stakeholder interviews, and 95 transfers were completed during the preintervention period. During the postintervention period, 145 handoffs were audited. We observed significant reductions in transfer latency, unnecessary handoffs, and cumulative provider handoff time. Overnight transfers decreased, and no negative impact was observed in reported safety events or bouncebacks. Survey results showed a positive impact on collaboration, efficiency, and satisfaction among team members. Conclusions: Developing safer handoff practices require a collaborative, structured, and stepwise approach. Advances are attainable in high-volume centers, and comprehensive measurement of change is necessary to ensure a positive impact on the overall patient and provider environment.
