OBJECTIVES To assess the extended feasibility of a telerehabilitation program and its effects on physical performance in older adults who have recently undergone transcatheter aortic valve implantation (TAVI).METHODS In this single-center feasibility study, patients underwent an eight-week telerehabilitation program, involving webbased home exercise training twice weekly, an activity tracker, access to an informative website, and one online session with a nurse, starting one-week postoperative. Data collection was performed before surgery and three months postoperative. The feasibility of the intervention was based on recruitment and adherence to the program. As a secondary outcome, we evaluated the change in six-minute walk distance from before surgery to three months postoperative.
RESULTSForty-one patients scheduled for TAVI were assessed for eligibility; 15 patients (37%) were enrolled. Of these, eight were excluded after surgery due to tiredness (n = 2), non-cardiac related hospital readmission (n = 2), fluctuating health (n = 1), death during hospital stay (n = 1), and reduced cognition (n = 2). Seven patients completed the eight-week web-based intervention and were evaluated three months postoperative. Their median (IQR) age was 83 [81, 87] years, and the sample comprised three men and four women. Their walked distance improved from median (IQR) 262 [199, 463] before surgery, to 381 [267, 521] meters three months postoperative. No adverse events were reported.CONCLUSION Web-based telerehabilitation, including supervised exercise training, in older adults who have recently undergone TAVI was feasible for a small number of patients who completed the eight-week intervention. This was reflected in an improvement in their walked distance three months after the surgery. However, the low recruitment and retention rates do question the overall feasibility of this intervention in a frail, older population of post-TAVI patients.T ranscatheter aortic valve implantation (TAVI) is the standard of care for treatment of severe aortic valve stenosis, especially in patients of old age or who are deemed to be at high perioperative mortality risk. [1,2] The benefits of TAVI are reduced mortality [3,4] and improved quality of life, [5][6][7] particularly in terms of increased mobility and usual activities of daily living. [5,8] Cardiac rehabilitation (CR) is recommended following TAVI to improve functional capacity and qu-ality of life, [9][10][11] while reducing mortality. [12] However, referral to or participation in CR in this particular population is low. [13][14][15] Cardiac telerehabilitation (CTR), defined as the use of information and communication technologies to support rehabilitation, [16,17] has proven to be as effective as center-or hospital-based CR in improving functional outcomes and reducing morbidity and mortality, [18,19] as well as improving patient activation and health literacy, [20] while being cost-effective. [21] Thus, CTR
