Background
Single ventricle patients eligible for Fontan completion routinely undergo pre-Fontan catheterization for complete hemodynamic and anatomic assessment prior to surgery. Cardiac MRI (cMRI) may be used to evaluate pre-Fontan anatomy and collateral burden. We aim to describe our center’s outcomes in patients undergoing a pre-Fontan catheterization combined with a cMRI.
Methods
A retrospective review of patients undergoing pre-Fontan catheterization from 10/2018 to 10/2020 at Texas Children’s Hospital was performed. Patients were divided into 2 groups: combined cMRI and catheterization and those who received catheterization only.
Results
Combined cMRI and catheterizations were performed 29 times in 28 patients and 29 catheterizations alone were performed in 29 patients. Both groups were similar in age and weight (Table 1). Patients undergoing combined procedures have lower fluoroscopy time, contrast dose, in-lab time, and catheterization procedure time. Intubation time and total anesthesia times were higher in the combined procedure group (Table 1). Patients undergoing a combined procedure were less likely to have a catheter-based intervention performed than in the non-cMRI group. Bypass time, ICU LOS and chest tube duration were similar in the 2 groups (Table 1).
Conclusions
Pre-Fontan assessment including catheterization and cMRI decreases morbidities associated with cardiac catheterization at the expense of longer anesthetic times, and results in similar acute Fontan outcomes compared to when cardiac catheterization alone is utilized.
