Understanding experiences of undergoing transcatheter aortic valve implantation: one-year follow-up
Bibliographic record
Abstract
BACKGROUND: Transcatheter aortic valve implantation (TAVI) is the treatment of choice for frail, older adults with severe symptomatic aortic stenosis. Although research about long-term clinical outcomes is emerging, there is limited evidence from the perspectives of patients and family caregivers on their perceived benefits and challenges after TAVI. AIMS: The aim of this study was to describe older adults and family caregivers' perspectives on undergoing TAVI at one year post-procedure. METHODS: Qualitative description was the method of inquiry. A purposive sample of 31 patients and 15 family caregivers was recruited from a TAVI programme in western Canada. Semi-structured interviews were conducted with participants one year after TAVI. Data were analysed thematically. RESULTS: All participants were satisfied with the decision to undergo TAVI. There were three central themes. First, recovery was experienced in the context of aging and comorbidities, which was shaped by patients' limited options for care and post-procedure symptom burden. Second, reconciling expectations with reality meant that, for some patients, symptom burden remained prevalent and was also influenced by others' expectations. Third, recommendations for recovery related to having information needs met, keeping informed of evolving care processes, and addressing individualised needs for support. CONCLUSIONS: The perspectives of participants provide a valuable contribution to the literature about undergoing TAVI. Clinicians need to be attentive to patients' expectations of benefit and temper these with consideration of the individual's broader health situation to provide treatment decision support. Patients and family caregivers also need adequate teaching and support to facilitate safe transition home given the shift towards early discharge after TAVI.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
