Current practice of care for adolescent and adult patients after Fontan surgery in Poland.

ABSTRACT

BACKGROUND: The growing number of adult patients after the Fontan operation requires regular surveillance tests in specialized centers. AIMS: Our study aimed to evaluate the current practice of care for Fontan patients in Poland using a multicenter survey. METHODS: Eight centers were included in the study including 5 adult congenital heart disease (ACHD) and 3 pediatric centers for adolescents. To compare the centers and facilitate interpretation of results, the Fontan Surveillance Score (FSS) was developed. The higher score is consistent with better care, with a maximum of 19 points. RESULTS: We included in the study 398 Fontan patients (243 adults and 155 adolescents [aged 14-18 years]). The median FSS was 13 points with variability between centers (interquartile range 7-14 points). Centers providing continuous care from the pediatric period until 18 years of age achieved a higher FSS compared to ACHD centers (median 14 points vs. 12 points; P <0.001). Most of the patients, both in the ACHD (82.3%) and pediatric centers (89%), were seen annually and had a physical examination, electrocardiogram, and echocardiogram performed at each visit. However, we observed unsatisfactory utilization of tests identifying early stages of Fontan circulation failure (cardiopulmonary exercise tests, cardiac magnetic resonance, liver biochemistry and imaging, detection of protein-losing enteropathy). CONCLUSIONS: Our results showed that there is no unified surveillance approach for Fontan patients in Poland. The practice of care for adults differs from that of adolescents.
