The design\/setting of the evaluation is in a large case-series of preterm infants with CD and PH. Data of all preterm infants (gestational age (GA)\u2009<\u200937\u00a0weeks) with levosimendan treatment and CD and\/or PH in the echocardiographic assessment between 01\/2018 and 06\/2021 were screened for analysis. The primary clinical endpoint was defined as echocardiographic response to levosimendan. Preterm infants (105) were finally enrolled for further analysis. The preterm infants (48%) were classified as extremely low GA newborns (ELGANs,\u2009<\u200928\u00a0weeks of GA) and 73% as very low birth weight infants (<\u20091500\u00a0g, VLBW). The primary endpoint was reached in 71%, without difference regarding GA or BW. The incidence of moderate or severe PH decreased from baseline to follow-up (24\u00a0h) in about 30%, with a significant decrease in the responder group (\n p<\/jats:italic>\n \u2009<\u20090.001). The incidence of left ventricular dysfunction and bi-ventricular dysfunction decreased significantly from baseline to follow-up (24\u00a0h) in the responder-group (\n p<\/jats:italic>\n \u2009=\u20090.007, and\n p<\/jats:italic>\n \u2009<\u20090.001, respectively). The arterial lactate level decreased significantly from baseline (4.7\u00a0mmol\/l) to 12\u00a0h (3.6\u00a0mmol\/l,\n p<\/jats:italic>\n \u2009<\u20090.05), and 24\u00a0h (3.1\u00a0mmol\/l,\n p<\/jats:italic>\n \u2009<\u20090.01).\n <\/jats:p>\n \n \u00a0 Conclusion<\/jats:italic>\n : Levosimendan treatment is associated with an improvement of both CD and PH in preterm infants, with a stabilization of the mean arterial\u00a0pressure during the treatment and a significant decrease of arterial lactate levels. Future prospective trials are highly warranted.\n \n \n \n \n \n What is Known:<\/jats:bold>\n <\/jats:td>\n <\/jats:tr>\n \n \n \u2022\n Levosimendan as a calcium-sensitizer and inodilator is known to improve the low cardiac output syndrome (LCOS), and improves ventricular dysfunction, and PH, both in pediatric as well as in adult populations. Data related to critically ill neonates without major cardiac surgery and preterm infants are not available.<\/jats:italic>\n <\/jats:td>\n <\/jats:tr>\n \n \n What is New:<\/jats:bold>\n <\/jats:td>\n <\/jats:tr>\n \n \n \u2022\n This study evaluated the effect of levosimendan on hemodynamics, clinical scores, echocardiographic severity parameters, and arterial lactate levels in a case-series of 105 preterm infants for the first time. Levosimendan treatment in preterm infants is associated with a rapid improvement of CD and PH, an increase of the mean arterial pressure, and a significant decrease in arterial lactate levels, as surrogate marker for a LCOS.<\/jats:italic>\n <\/jats:td>\n <\/jats:tr>\n \n \n \u2022\n How this study might affect research, practice, or policy. As no data are available regarding the use of levosimendan in this population, our results hopefully animate the research community to conduct future prospective trails analyzing levosimendan in randomized controlled trials (RCT) and observational control studies. Additionally, our results potentially motivate clinicians to introduce levosimendan as second second-line \ntherapy in cases of severe CD and PH in preterm infants without improvement using standard treatment strategies.<\/jats:italic>\n <\/jats:td>\n <\/jats:tr>\n <\/jats:tbody>\n <\/jats:table>\n <\/jats:table-wrap>\n <\/jats:p>","DOI":"10.1007\/s00431-023-04971-9","type":"journal-article","created":{"date-parts":[[2023,4,26]],"date-time":"2023-04-26T21:01:56Z","timestamp":1682542916000},"page":"3165-3174","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Evaluation of levosimendan as treatment option in a large case-series of preterm infants with cardiac dysfunction and pulmonary hypertension"],"prefix":"10.1007","volume":"182","author":[{"given":"Lukas","family":"Schroeder","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanley","family":"Holcher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judith","family":"Leyens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annegret","family":"Geipel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brigitte","family":"Strizek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Till","family":"Dresbach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Mueller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian","family":"Kipfmueller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,4,27]]},"reference":[{"issue":"3","key":"4971_CR1","doi-asserted-by":"publisher","first-page":"217","DOI":"10.1159\/000314955","volume":"99","author":"MC Bravo","year":"2011","unstructured":"Bravo MC, L\u00f3pez P, Caba\u00f1as F, P\u00e9rez-Rodr\u00edguez J, P\u00e9rez-Fern\u00e1ndez E, Quero J, Pellicer A (2011) Acute effects of levosimendan on cerebral and systemic perfusion and oxygenation in newborns: an observational study.
