          Zusammenfassung

          Die Mortalität von Patienten mit isoliert auftretenden angeborenen Zwerchfellhernien liegt in spezialisierten Zentren bei 20–40%. Wesentliche, das Outcome beeinflussende Faktoren, sind die bestehende Lungenhypoplasie, eine daraus resultierende pulmonale Hypertonie, sowie das Vorliegen weiterer Fehlbildungen. Begleitfehlbildungen wie angeborene Herzfehler treten bei ca. 18% aller Neonaten mit Zwerchfellhernie auf. Schwere angeborene Herzfehler wie das hypoplastische Linksherz Syndrom zeigen sich in ca. 8% der Fälle. In einer retrospektiven Analyse des Patientenkollektivs unserer Klinik zwischen 01/2012 und 12/2018 wurde das prä- und postnatale Management, sowie das Outcome von Neugeborenen mit der Kombination aus angeborenen Herzfehlern und Zwerchfellhernien untersucht. Im Studienzeitraum wurden in unserer Klinik 156 Neugeborene mit Zwerchfellhernie behandelt. Bei 10 Patienten (6,4%) lag zusätzlich ein schwerer, bei 11 Patienten (7,1%) ein moderater Herzfehler vor. 6/21 Patienten verstarben im Verlauf des Krankenhausaufenthaltes, davon 3 am ersten Lebenstag. Es zeigte sich eine deutlich geringere Mortalität bei Patienten mit Zwerchfellhernie und moderatem Herzfehler im Vergleich zu schwerem Herzfehler (9 vs. 50%). Besonders hoch lag die Mortalität bei Kindern mit einem univentrikulären Herzen. Trotz einer deutlich reduzierten Prognose bei der Kombination aus angeborenem Herzfehler und Zwerchfellhernie muss nicht generell mit einer infausten Prognose gerechnet werden. In spezialisierten Zentren kann ein kurativer Ansatz erfolgen.

          Abstract

          The mortality of patients with isolated congenital diaphragmatic hernia (CDH) in specialized centers is 20–40%. The main factors influencing the outcome are the underlying pulmonary hypoplasia, the resulting pulmonary hypertension and the presence of other malformations. Concomitant malformations such as congenital heart defects occur in around 18% of all neonates with a diaphragmatic hernia. Serious congenital heart defects such as hypoplastic left heart syndrome occur in approximately 8% of cases. In a retrospective analysis of the patient collective of our hospital between 01/2012 and 12/2018, the prenatal and postnatal management as well as the outcome of newborns with a combination of congenital heart defects and diaphragmatic hernias were examined. During the study period, 156 newborns with diaphragmatic hernias were treated at our institution. In 10 patients (6.4%) there was also a severe, and in 11 patients (7.1%) a moderate heart defect. 6/21 patients died during their hospital stay, 3 of them on the first day of life. There was a significantly lower mortality in patients with diaphragmatic hernia and moderate heart defects compared to severe heart defects (9 vs. 50%). The mortality in children with a univentricular heart was particularly high. Despite a significantly reduced prognosis for the combination of congenital heart defects and diaphragmatic hernia, generally a poor prognosis does not have to be expected. A curative approach can be achieved in specialized centers.

          Standardized Postnatal Management of Infants with Congenital Diaphragmatic Hernia in Europe: The CDH EURO Consortium Consensus - 2015 Update.

          In 2010, the congenital diaphragmatic hernia (CDH) EURO Consortium published a standardized neonatal treatment protocol. Five years later, the number of participating centers has been raised from 13 to 22. In this article the relevant literature is updated, and consensus has been reached between the members of the CDH EURO Consortium. Key updated recommendations are: (1) planned delivery after a gestational age of 39 weeks in a high-volume tertiary center; (2) neuromuscular blocking agents to be avoided during initial treatment in the delivery room; (3) adapt treatment to reach a preductal saturation of between 80 and 95% and postductal saturation >70%; (4) target PaCO2 to be between 50 and 70 mm Hg; (5) conventional mechanical ventilation to be the optimal initial ventilation strategy, and (6) intravenous sildenafil to be considered in CDH patients with severe pulmonary hypertension. This article represents the current opinion of all consortium members in Europe for the optimal neonatal treatment of CDH.

            An empirically based tool for analyzing mortality associated with congenital heart surgery.

            Analysis of congenital heart surgery results requires a reliable method of estimating the risk of adverse outcomes. Two major systems in current use are based on projections of risk or complexity that were predominantly subjectively derived. Our goal was to create an objective, empirically based index that can be used to identify the statistically estimated risk of in-hospital mortality by procedure and to group procedures into risk categories. Mortality risk was estimated for 148 types of operative procedures using data from 77,294 operations entered into the European Association for Cardiothoracic Surgery (EACTS) Congenital Heart Surgery Database (33,360 operations) and the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database (43,934 patients) between 2002 and 2007. Procedure-specific mortality rate estimates were calculated using a Bayesian model that adjusted for small denominators. Each procedure was assigned a numeric score (the STS-EACTS Congenital Heart Surgery Mortality Score [2009]) ranging from 0.1 to 5.0 based on the estimated mortality rate. Procedures were also sorted by increasing risk and grouped into 5 categories (the STS-EACTS Congenital Heart Surgery Mortality Categories [2009]) that were chosen to be optimal with respect to minimizing within-category variation and maximizing between-category variation. Model performance was subsequently assessed in an independent validation sample (n = 27,700) and compared with 2 existing methods: Risk Adjustment for Congenital Heart Surgery (RACHS-1) categories and Aristotle Basis Complexity scores. Estimated mortality rates ranged across procedure types from 0.3% (atrial septal defect repair with patch) to 29.8% (truncus plus interrupted aortic arch repair). The proposed STS-EACTS score and STS-EACTS categories demonstrated good discrimination for predicting mortality in the validation sample (C-index = 0.784 and 0.773, respectively). For procedures with more than 40 occurrences, the Pearson correlation coefficient between a procedure's STS-EACTS score and its actual mortality rate in the validation sample was 0.80. In the subset of procedures for which RACHS-1 and Aristotle Basic Complexity scores are defined, discrimination was highest for the STS-EACTS score (C-index = 0.787), followed by STS-EACTS categories (C-index = 0.778), RACHS-1 categories (C-index = 0.745), and Aristotle Basic Complexity scores (C-index = 0.687). When patient covariates were added to each model, the C-index improved: STS-EACTS score (C-index = 0.816), STS-EACTS categories (C-index = 0.812), RACHS-1 categories (C-index = 0.802), and Aristotle Basic Complexity scores (C-index = 0.795). The proposed risk scores and categories have a high degree of discrimination for predicting mortality and represent an improvement over existing consensus-based methods. Risk models incorporating these measures may be used to compare mortality outcomes across institutions with differing case mixes.
