RESUMO
The role of extracorporeal membrane oxygenation (ECMO) in the management of severely ill patients with coronavirus disease 2019 (COVID-19) continues to evolve. The purpose of this study is to review a multi-institutional clinical experience in 100 consecutive patients, at 20 hospitals, with confirmed COVID-19 supported with ECMO. This analysis includes our first 100 patients with complete data who had confirmed COVID-19 and were supported with ECMO. The first patient in the cohort was placed on ECMO on March 17, 2020. Differences by the mortality group were assessed using χ2 tests for categorical variables and Kruskal-Wallis rank-sum tests and Welch's analysis of variance for continuous variables. The median time on ECMO was 12.0 days (IQR = 8-22 days). All 100 patients have since been separated from ECMO: 50 patients survived and 50 patients died. The rate of survival with veno-venous ECMO was 49 of 96 patients (51%), whereas that with veno-arterial ECMO was 1 of 4 patients (25%). Of 50 survivors, 49 have been discharged from the hospital and 1 remains hospitalized at the ECMO-providing hospital. Survivors were generally younger, with a lower median age (47 versus 56.5 years, p = 0.014). In the 50 surviving patients, adjunctive therapies while on ECMO included intravenous steroids (26), anti-interleukin-6 receptor blockers (26), convalescent plasma (22), remdesivir (21), hydroxychloroquine (20), and prostaglandin (15). Extracorporeal membrane oxygenation may facilitate salvage and survival of selected critically ill patients with COVID-19. Survivors tend to be younger. Substantial variation exists in the drug treatment of COVID-19, but ECMO offers a reasonable rescue strategy.

Following several years of planning and design, the World Database for Pediatric and Congenital Heart Surgery (WDPCHS) went live on January 1, 2017. The first operational year of this valuable database has proven very successful. As of February 28, 2018, more than 4,500 patients have been submitted from 39 centers; participation currently spans 19 countries over 6 continents, with 120 more centers in the enrollment pipeline. This update, the first in a series, is intended to provide World Society for Pediatric and Congenital Heart Surgery members and others who care for children with congenital heart disease with a broad overview of current progress and ongoing activities surrounding the WDPCHS.

BACKGROUND: The balance of hemostasis and anticoagulation is a concern for patients dependent upon ventricular assist devices (VADs). Bleeding is a common complication with both short- and long-term use of these devices. A better understanding of the risk factors and etiologies of bleeding associated with these devices is needed and could improve the overall results. We sought to determine the relationship of mechanical circulatory assist device use with acquired von Willebrand disease (avWD) in children. METHODS: Data were analyzed retrospectively via review of the medical record of 19 consecutive patients who were supported with the Berlin EXCOR VAD for greater than 24 hours. Laboratory testing for avWD was performed at the discretion of the clinical team, often in association with clinical bleeding. RESULTS: Of 19 pediatric patients, 10 (52.6%) had laboratory testing consistent with avWD. Median time to detection of avWD was 35 days postimplantation of device (range 0-310 days). Both minor mucosal bleeding and bleeding requiring intervention were highly prevalent in patients in whom avWD was identified (10/10 [100%] and 7/10 [70%]). The mean age of all patients was 3.3 years, but patients found to have avWD tended to be older (mean 5.3 years) and supported with larger volume VADs. CONCLUSIONS: This experience demonstrates a high prevalence of avWD following EXCOR implantation. Bleeding, older age, and larger VAD size may be associated with avWD. These results should stimulate critical evaluation of individualized anticoagulation regimens in pediatric VAD patients.

BACKGROUND: We describe in utero anatomic evolution and postnatal outcome of complete common atrioventricular canal defect (CCAVCD). METHODS: Retrospective data on 31 fetuses with CCAVCD were analyzed. We reviewed prenatal and postnatal echocardiograms, karyotype, and postnatal outcomes. RESULTS: A total of 20 fetuses had complete data, 18 with serial fetal echocardiograms and postnatal data and 2 terminations. At initial examination, isolated CCAVCD was seen in 12 (67%) fetuses while 6 (33%) were associated with heterotaxy syndrome. On follow-up, 4 fetuses (22%) had spontaneous closure of the inlet ventricular septal defect (VSD) component of the CCAVCD, seen both at 30 to 35 weeks of gestation and on postnatal echocardiograms. These 4 fetuses had previously demonstrated CCAVCD between 18 and 25 weeks of gestation. A total of 15 (83%) patients underwent operative correction, 10 with isolated complete atrioventricular septal defect and 5 with heterotaxy had surgical repair. Four infants in whom spontaneous intrauterine closure of the VSD component was observed had no VSD noted at surgery and underwent closure of primum atrial septal defect and repair of the left atrioventricular (AV) valve cleft. CONCLUSIONS: Our data demonstrate that CCAVCD diagnosed during fetal life is not a static anomaly. In our series, an inlet VSD less than 4 mm and Rastelli type A anatomy (AV valve attachment to septal crest) during second trimester may evolve during third trimester by formation of AV sulcus pouch and spontaneous closure of the VSD. To the best of our knowledge, this is the first study to report such anatomic evolution of CCAVCD in the fetus. This information is vital for appropriate counseling for expectant parents.

The Jatene arterial switch operation (ASO) for dextro-transposition of the great arteries is ideally performed within the first 2 weeks of life. Clinical circumstances, however, may dictate a delayed ASO and left ventricle "retraining" prior to the procedure. Glucocorticoid remediable aldosteronism (GRA) accounts for 0.5% to 1% of primary aldosteronism. It presents as severe hypertension in infants and children, with poor response to standard antihypertensive medications. To the authors' knowledge, this is the first reported case of GRA in the context of transposition physiology. The management of GRA and a rationale for delayed ASO are discussed.
