ABSTRACT
BACKGROUND: In 2014 a professional collaboration was established between IRCCS Policlinico San Donato, Milan, Italy (PSD) and the Institute for Cardiovascular Disease Dedinje, Belgrade, Serbia (ICDD) to support and improve the care of adult patients with congenital heart disease (ACHD) in the country. Since 2018, this collaboration has become more structured, with a specific focus on surgery for adults with complex congenital heart disease (CHD). Aim of the study was to evaluate the outcomes of this collaboration.
METHODS: We conducted a retrospective study on all consecutive adult patients (aged over 18 years) with CHD who underwent surgery at the Institute for Cardiovascular Disease Dedinje (ICDD) over a ten-year period, from January 2014 to December 2024. Collected data included number of cases, mean age at surgery, types of surgical procedures performed, number of previous operations, distribution of cases based on complexity, patient outcomes, and follow-up.
RESULTS: Between 2014 and 2024, a total of 244 ACHD patients underwent surgery at ICDD. Eighty-eight of these patients (88/244 = 36%) required complex procedures and were referred to the visiting PSD cardiac surgeon. Mean age at surgery was 34.8 years (±14 years). The most common diagnosis was right ventricular outflow tract (RVOT) pathology, accounting for 89% of cases. Seventy patients (80%) underwent reoperations following previous procedures. In-hospital mortality was 4.5% (4 patients). No additional deaths or reoperations occurred during a mean follow-up of 58 months (2-122 months).
CONCLUSIONS: This ten-year international partnership demonstrates that high-quality ACHD surgical care can be delivered sustainably in countries with limited case volumes and expertise. By combining local access with external specialist support, the model has achieved outcomes comparable to high-volume Western European centres. Increased access to ACHD surgery in their home country and reduced financial burden suggests that this model of care may potentially serve in other countries facing similar healthcare challenges.
