Does the Toronto Aortic Stenosis Quality of Life Questionnaire (TASQ) reliably and validly measure quality of life changes in patients with severe aortic stenosis undergoing TAVI?
The TASQ is a valid, reliable, and responsive disease-specific tool for assessing quality of life in patients with severe aortic stenosis undergoing TAVI.
Standardized Mean Difference: 0.99
p-value: p=<0.0001
BACKGROUND: Aortic stenosis (AS) is a common cardiac condition whose prevalence increases with age. The symptom burden associated with severe aortic stenosis (AS) can introduce significant lifestyle disruptions and if left untreated can lead to a poor prognosis. Quality of life (QoL) is an important consideration in these patients. The TASQ is a QoL tool that was developed for aortic stenosis patients. We evaluated the psychometric properties of this specific questionnaire in patients who underwent transcatheter aortic valve implantation (TAVI), which is a therapeutic option for patients with severe aortic stenosis (AS). METHODS: The properties of the TASQ in measuring QoL were evaluated in AS patients undergoing TAVI. Patients presenting for the TAVI procedure (N = 62) were evaluated pre-TAVI, at discharge, 1-month, and 3-month follow-ups. Demographic information as well as caregiver status, and daily activities were recorded. In addition to the TASQ, they completed the KCCQ (Kansas City Cardiomyopathy Questionnaire) and the IIRS (Illness Intrusiveness Rating Scale). RESULTS: The TASQ is a 16-item self-administered questionnaire that assesses AS-specific QoL across five domains: physical symptoms; physical limitations; emotional impact; social limitations, and health expectations. TASQ subscales are internally consistent (α = 0.74-0.96) and showed significant improvements from baseline across assessments (p < 0.001). Construct validity evidence was demonstrated by correlations consistent with theoretically derived hypotheses across time points. CONCLUSIONS: The TASQ is a brief measure of AS-specific QoL that is sensitive to change in patients undergoing TAVI. Items on the TASQ capture important QoL concerns reported by AS patients, suggesting this is a measure of relevant and meaningful outcomes for this patient population. Detection of early improvements in QoL by the TASQ is promising, with important implications for the evaluation of procedural outcomes in this population.
Styra et al. (Tue,) conducted a observational in Severe aortic stenosis (n=62). Transcatheter aortic valve implantation (TAVI) vs. Pre-TAVI baseline was evaluated on Change in total TASQ score from baseline to 3-month follow-up (d = 0.99, p=<0.0001). The Toronto Aortic Stenosis Quality of Life (TASQ) questionnaire detected significant improvements in quality of life from baseline to 3 months post-TAVI (d = 0.99, p < 0.0001).
