Summary: | Abstract only
Objective:
The repair of tetralogy of Fallot (ToF) using a transannular patch can result in progressive pulmonary valve annulus (PVA) dilation, preventing the option of a future catheter-based pulmonary valve replacement and requiring early reoperation. A rigid Dacron limited transannular patch (LTAP) that nominally expands the PVA may prevent long-term annular dilation and reoperation.
Hypothesis:
Infants following a LTAP would have similar rates of PVA growth compared to infants requiring only a subvalvar (SV) repair.
Methods:
Infants < 1 year between 1998-2018 requiring a SV or LTAP ToF repair were divided into two groups based on the surgical approach. Pre-operative and serial follow-up echocardiograms quantified the PVA diameter and corresponding Z-Score at 5, 10, and 15 years. Multivariate analysis examined the risk factors for reoperation.
Results:
From 232 ToF repairs (LTAP-94; SV-138), the LTAP group was significantly younger (103±53 vs. 138±67 days; p |
