What is Construct Validity Of The Kansas City Cardiomyopathy Questionnaire In Adults With Congenital Heart Disease about?

Background: The Kansas City Cardiomyopathy Questionnaire (KCCQ) is an FDA approved quality of life survey validated in the non-congenital heart failure population. Although physiologic failure (PF) in the adult congenital heart disease (ACHD) population is heterogenous, there may be utility for the KCCQ in this group. Our aim is to demonstrate construct validity of the KCCQ in an ambulatory sample of ACHD patients. Methods: We conducted a single center, cross sectional study of patients who completed the KCCQ in our ACHD clinic. KCCQ overall scores were compared to physician assessments of PF as well as patient and disease demographics. Spearmanʼs correlation and Mann Whitney U test were used for continuous and categorical variables, respectively. Results: In total, 90 ACHD patients completed 108 KCCQs. Mean overall KCCQ scores for patients deemed to have PF by their physician were lower compared to those without PF (67.9 vs. 84.0, p<0.001). Lower overall KCCQ scores were associated with worse NYHA scores (r=-0.46, p<0.001, CI[-0.60, -0.29]), worse ACHD physiologic stage (r=-0.4, p<0.001, CI[-0.55, -0.23]), increasing ACHD anatomic complexity (r=-0.27, p=0.005, CI[-0.44, -0.08]), a
