Abstract 20897: Patient-Reported Outcomes in Tetralogy of Fallot: Baseline Results From a Prospective, International, Multi-Site Study

Introduction: In addition to understanding causes of morbidity and mortality following tetralogy of Fallot repair (rTOF), the importance of patient-reported outcomes (PROs) such as quality of life (QOL) is increasingly being recognized. Hypothesis: We hypothesized that PROs in rTOF would be associated with selected sociodemographic factors, functional status, and/or clinical variables. Methods: As part of a prospective study of patients ≥12 years with rTOF and significant pulmonary regurgitation, participants completed PRO surveys: SF-12 Health Status (physical component summary [PCS] and mental component summary [MCS] t-scores), EQ-5D (5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), and a 0-100 QOL linear analogue scale (QOL-LAS). With multivariable regression analysis, we determined the association between PROs and selected predictors. Results: We studied n=627 participants (55% male, 26±13 years, 75% adult) at 14 sites (North America, Europe and Asia). Med...
