Abstract

Introduction: Cases of Fontan failure with normal Fontan pressure have been reported. This study aimed to identify catheterisation-derived haemodynamic predictors of heart transplantation/death, other than Fontan pressure, in late post-Fontan patients.

Methods: This retrospective study evaluated post-Fontan patients who underwent cardiac catheterisation at age ≥10 years between 1993 and 2018. The predictive effect of cardiac index-systemic vascular resistance index plot and perfusion pressure on freedom from the primary outcome (heart transplantation/death) was evaluated. Patients were categorised into haemodynamic categories A (cardiac index ≥ 3, systemic vascular resistance index ≥ 13), B (cardiac index < 3, systemic vascular resistance index ≥ 13), C (cardiac index ≥ 3, systemic vascular resistance index < 13), and D (cardiac index < 3, systemic vascular resistance index < 13).

Results: In total, 79 patients (median age: 15.7 [range: 10.1-50.2] years) were included; of them, the primary endpoint occurred in 10 (13%; median follow-up: 1.9 [range: 0.1-18.8] years). Category C patients had significantly shorter freedom from the endpoint than categories A and B patients. Univariate analysis identified significant haemodynamic predictors, including Fontan pressure, pulmonary/systemic vascular resistance index, pulmonary/systemic flow, systemic arterial oxygen saturation, systemic venous oxygen saturation, systemic vascular resistance index, perfusion pressure, perfusion pressure < 53 mmHg, and category C. In multivariable analysis, perfusion pressure < 53 mmHg and category C emerged as predictors of heart transplantation/death alongside Fontan pressure.

Conclusion: Haemodynamic profiling of late post-Fontan patients using the cardiac index-systemic vascular resistance index plot can aid to comprehend the post-Fontan status and predict clinical prognosis.

期刊介绍: Cardiology in the Young is devoted to cardiovascular issues affecting the young, and the older patient suffering the sequels of congenital heart disease, or other cardiac diseases acquired in childhood. The journal serves the interests of all professionals concerned with these topics. By design, the journal is international and multidisciplinary in its approach, and members of the editorial board take an active role in the its mission, helping to make it the essential journal in paediatric cardiology. All aspects of paediatric cardiology are covered within the journal. The content includes original articles, brief reports, editorials, reviews, and papers devoted to continuing professional development.
