Transcatheter Aortic Valve Replacement vs. Surgical Aortic Valve Replacement for Long-Term Mortality Due to Stroke and Myocardial Infarction: A Meta-Analysis during the COVID-19 Pandemic.

Background and objectives: One of the leading causes of mortality and morbidity in people over the age of 50 is stroke. The acceptance of transcatheter aortic valve replacement (TAVR) as a treatment option for severe symptomatic aortic stenosis (AS) has increased as a result of numerous randomized clinical trials comparing surgical aortic valve replacement (SAVR) and TAVR in high- and intermediate-risk patients, showing comparable clinical outcomes and valve hemodynamics. Materials and Methods: An electronic search of Medline, Google Scholar and Cochrane Central was carried out from their inception to 28 September 2022 without any language restrictions. Results: Our meta-analysis demonstrated that, as compared with SAVR, TAVR was not linked with a lower stroke ratio or stroke mortality. It is clear from this that the SAVR intervention techniques applied in the six studies were successful in reducing cardiogenic consequences over time. Conclusions: A significantly decreased rate of mortality from cardiogenic causes was associated with SAVR. Additionally, when TAVR and SAVR were compared for stroke mortality, the results were nonsignificant with a p value of 0.57, indicating that none of these procedures could decrease stroke-related mortality.

How to Reduce Inequity of Access to Cardiac Rehabilitation After Surgical Aortic Valve Replacement. Recommendations for the Post-COVID-19 Era From a Real-World, Population-Based Study.

PURPOSE: Cardiac rehabilitation (CR) is a class I recommendation after valvular surgery. Few data exist on the level of access to CR after surgical aortic valve replacement (SAVR), and the factors affecting the probability of timely access to CR after SAVR have never been empirically investigated. This study aims at estimating the proportion of SAVR patients who initiated timely CR and understanding to what extent timely access to CR for SAVR patients is influenced by specific characteristics of patients and hospitals. METHODS: We conducted a real-world, retrospective, population-based study by identifying from the Italian National Hospital Discharge Records all the discharged alive SAVR patients who accessed timely CR from 2009-2016. Two different cutoffs for timely access were considered, i.e. one and 21 days after discharge. A unique dataset was constructed by merging several data sources. Multiple logistic regressions were performed to identify the factors influencing the probability to access to timely CR. FINDINGS: 107,545 patients underwent SAVR in Italy from 2009-2016 and were discharged alive. Overall, 71,593 SAVR patients (66.6%) accessed timely CR, with an increasing trend over time. Additional 6,149 patients (5.7%) started CR from 2-21 days after discharge, slightly decreasing over time. The probability of timely CR (one-day cutoff) was significantly higher in older (OR=1.025, p<0.001) female patients (OR = 1.003, p<0.05) and patients with cardiovascular and cerebrovascular comorbidities. Presence of rehabilitation wards and number of rehabilitation beds in the index hospital significantly increased the probability of timely access to CR (OR = 1.105, p<0.001 and OR = 1.006, p<0.001 respectively). Patients hospitalized in private teaching hospitals had the highest predicted probability of timely CR after SAVR. A substantial variation in access to CR was found across Italian regions. Similar results were obtained with the alternative 21-days cutoff. IMPLICATIONS: Approximately one-third of SAVR patients did not benefit from CR in Italy, mainly due to shortness of rehabilitation facilities, with relevant disparities across the country. The cessation of CR services during the COVID-19 pandemic provides the opportunity to re-think and innovate CR, shifting from center-based to home-based models. Digital health technologies can supplement traditional health services and grant safe, effective, and equitable access to care, especially for countries with insufficient rehabilitation bed capacity. As CR is associated with better outcomes, we recommend decision-makers to use our results to plan adequate healthcare services, also investing in digital health, to ensure patients' access to cost-effective care.

Monitoring Patients Reported Outcomes after Valve Replacement Using Wearable Devices: Insights on Feasibility and Capability Study: Feasibility Results.

Wearable devices (WDs) can objectively assess patient-reported outcomes (PROMs) in clinical trials. In this study, the feasibility and acceptability of using commercial WDs in elderly patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) will be explored. This is a prospective observational study. Participants were trained to use a WD and a smartphone to collect data on their physical activity, rest heart rate and number of hours of sleep. Validated questionnaires were also used to evaluate these outcomes. A technology acceptance questionnaire was used at the end of the follow up. In our participants an overall good compliance in wearing the device (75.1% vs. 79.8%, SAVR vs. TAVR) was assessed. Half of the patients were willing to continue using the device. Perceived ease of use is one of the domains that scored higher in the technology acceptance questionnaire. In this study we observed that the use of a WD is accepted in our frail population for an extended period. Even though commercial WDs are not tailored for clinical research, they can produce useful information on patient behavior, especially when coordinated with intervention tailored to the single patient.
