Quality of Life After Transcatheter Aortic Valve Implantation

This observational cohort study investigates whether hemodynamic improvements following transcatheter aortic valve implantation (TAVI) are associated with improvements in patient-reported quality of life among patients in Western Denmark. Quality of life will be assessed using the Kansas City Cardiomyopathy Questionnaire before TAVI and at follow-up. Changes in quality of life will be evaluated in relation to changes in mean transvalvular gradient, left ventricular ejection fraction, and New York Heart Association functional class. Clinical data will be obtained from patient records. Secondary analyses will explore whether patient characteristics, comorbidities, anatomical factors, and procedural characteristics are associated with quality-of-life improvement following TAVI. The study aims to improve understanding of the relationship between objective treatment outcomes and patients\' perceived health status after TAVI.
