The impact of tricuspid regurgitation on timing pulmonary valve replacement in ACHD patients after tetralogy of Fallot repair

Background: The emerging role of tricuspid regurgitation in the long-term outcome of the general population, poses the need for a review of its impact on patients with TOF and the timing for surgical PVR. Methods: This is a retrospective, single Centre study. Clinical, imaging and surgical data of a...

Description
Summary:Background: The emerging role of tricuspid regurgitation in the long-term outcome of the general population, poses the need for a review of its impact on patients with TOF and the timing for surgical PVR. Methods: This is a retrospective, single Centre study. Clinical, imaging and surgical data of adults with repaired TOF with a transannular patch repair were collected from our database. Results: 149 patients (61 % male, mean age of 26.0 years) were selected. At a follow-up time of 25.5 years (95 % CI 24.5,26.4) 92 patients required isolated PVR at a mean time from TOF repair of 16.6 years (95 % CI 15.5,17.7) and at a mean age of 17.9 years (95 % CI 16.8,19.0). In the whole cohort, significant TR was associated with a two-fold increase likelihood of requiring PVR (log-rank p = 0-0.0023, HR 2.02; 1.09-4-47). Moderate to severe TR was more frequent in those who underwent VSD closure through a right atriotomy (17 versus 0, p = 0.0002) and affected time to PVR (22.10 yrs versus 18.07 yrs). Despite significant RV volume overload, only 16 % of the entire cohort had TR more than moderate, and the degree of TR and tricuspid valve annulus diameter correlated better with atrial rather than ventricular volumes and areas (r = 0.346; p = 0.0068). Conclusions: TR severity of adults with transannula pacth repair of TOF correlats with surgical type of VSD closure and confers a two-fold increase in the likelihood of requiring PVR during follow-up. The close correlation of TV with atrial rather than ventricular volumes in this cohort suggests a link with the non-functional nature of TR.
