New Study Reveals High Mortality Rates in Neonatal Critical Congenital Heart Defects

Reading Time: 2 minutes

A new study conducted by the Turkish Neonatal Society has shed new light on the outcomes of neonates with critical congenital heart defects (CCHD) in Turkey. This comprehensive multicenter epidemiological study, spanning from October 2021 to November 2022, involved nine national tertiary health centres and marked a significant step in understanding the spectrum and outcomes of neonatal CCHD.

The study is pivotal in the field of paediatric cardiology, as it provides a detailed examination of the spectrum, management, and outcomes of 488 neonatal CCHD patients in Turkey. The research highlights the most common congenital heart defects (CHDs) encountered, with transposition of great arteries being the most prevalent, accounting for 19.5% of cases. This study is particularly relevant due to the high mortality and morbidity rates associated with CCHD, emphasising the need for early and accurate diagnosis and intervention.

The findings were published in the journal Pediatric Cardiology.

The research team collected data from various centres, examining critical variables such as demographic details, types of CHDs, the presence of extra-cardiac anomalies, and intervention strategies. A notable aspect of the study was the focus on both preoperative and postoperative periods, providing a holistic view of the patient journey. The study revealed that 325 of the patients underwent cardiac surgery, with aortic arch repair, arterial switch, and modified Blalock-Taussig shunt being the most common procedures.

However, despite advances in medical and surgical care, the study found an alarming in-hospital mortality rate of 20.1%, with postoperative mortality at 19.6%. These figures underscore the critical nature of CCHD and the challenges faced in managing these conditions. The study identified several risk factors for mortality, including the need for prostaglandin E1 before intervention, high vasoactive inotropic scores, the presence of major postoperative complications, and the need for early postoperative extracorporeal membrane oxygenation.

The study’s findings are crucial for healthcare professionals and policymakers, as they provide valuable insights into the epidemiology of CCHD in Turkey. The high mortality rate points to the need for further research to improve neonatal outcomes and establish more effective management protocols for these vulnerable patients. The study also emphasises the importance of multicenter collaborations to gather comprehensive data, which is essential for enhancing our understanding of complex medical conditions like CCHD.

One of the study’s strengths is its broad scope and the inclusion of a large number of patients, which provides a representative sample of neonatal CCHD cases in Turkey. However, the study also has its limitations, including the potential for variability in treatment approaches across different centres and the lack of long-term outcome data. These limitations highlight areas for future research and improvement in the management of CCHD.
