Patients' experiences of the transcatheter aortic valve implantation trajectory: A grounded theory study

The perspectives of older adults related to transcatheter aortic valve replacement: An integrative review

BACKGROUND

Aortic Stenosis (AS) is a common syndrome in older adults wherein the narrowing of the aortic valve impedes blood flow, resulting in advanced heart failure.1 AS is associated with a high mortality rate (50 % at 6 months if left untreated), substantial symptom burden, and reduced quality of life.1-3 Transcatheter aortic valve replacement (TAVR) was approved in 2012 as a less invasive alternative to surgical valve repair, offering a treatment for older frail patients. Although objective outcomes have been widely reported,4 the perspectives of older adults undergoing the TAVR process have never been synthesized.

OBJECTIVES

To contextualize the perspectives and experiences of older adults undergoing TAVR.

METHODS

An integrative review was conducted using Whittemore and Knafl's five-stage methodology.5 Four electronic databases were searched in April 2023. Articles were included if a qualitative methodology was used to assess the perceptions of older adults (>65 years old) undergoing or recovering from TAVR.

RESULTS

Out of 4619 articles screened, 12 articles met the criteria, representing 353 individuals from 10 countries. Relevant themes included the need for an individualized care plan, caregiver and family support, communication and education, persistent psychosocial and physical symptoms, and the unique recovery journey.

CONCLUSION

Older adults with AS undergoing TAVR generally perceive their procedure positively. Improved interdisciplinary and holistic management, open communication, symptom assessment, support, and education is needed.

How Smart are Smart Materials? A Conceptual and Ethical Analysis of Smart Lifelike Materials for the Design of Regenerative Valve Implants

It may soon become possible not just to replace, but to re-grow healthy tissues after injury or disease, because of innovations in the field of Regenerative Medicine. One particularly promising innovation is a regenerative valve implant to treat people with heart valve disease. These implants are fabricated from so-called 'smart', 'lifelike' materials. Implanted inside a heart, these implants stimulate re-growth of a healthy, living heart valve. While the technological development advances, the ethical implications of this new technology are still unclear and a clear conceptual understanding of the notions 'smart' and 'lifelike' is currently lacking. In this paper, we explore the conceptual and ethical implications of the development of smart lifelike materials for the design of regenerative implants, by analysing heart valve implants as a showcase. In our conceptual analysis, we show that the materials are considered 'smart' because they can communicate with human tissues, and 'lifelike' because they are structurally similar to these tissues. This shows that regenerative valve implants become intimately integrated in the living tissues of the human body. As such, they manifest the ontological entanglement of body and technology. In our ethical analysis, we argue this is ethically significant in at least two ways: It exacerbates the irreversibility of the implantation procedure, and it might affect the embodied experience of the implant recipient. With our conceptual and ethical analysis, we aim to contribute to responsible development of smart lifelike materials and regenerative implants.

Patient-centered empirical research on ethically relevant psychosocial and cultural aspects of cochlear, glaucoma and cardiovascular implants - a scoping review

BACKGROUND

The significance of medical implants goes beyond technical functioning and reaches into everyday life, with consequences for individuals as well as society. Ethical aspects associated with the everyday use of implants are relevant for individuals' lifeworlds and need to be considered in implant care and in the course of technical developments.

METHODS

This scoping review aimed to provide a synthesis of the existing evidence regarding ethically relevant psychosocial and cultural aspects in cochlear, glaucoma and cardiovascular implants in patient-centered empirical research. Systematic literature searches were conducted in EBSCOhost, Philpapers, PsycNET, Pubmed, Web of Science and BELIT databases. Eligible studies were articles in German or English language published since 2000 dealing with ethically relevant aspects of cochlear, glaucoma and passive cardiovascular implants based on empirical findings from the perspective of (prospective) implant-wearers and their significant others. Following a descriptive-analytical approach, a data extraction form was developed and relevant data were extracted accordingly. We combined a basic numerical analysis of study characteristics with a thematically organized narrative synthesis of the data.

RESULTS

Sixty-nine studies were included in the present analysis. Fifty were in the field of cochlear implants, sixteen in the field of passive cardiovascular implants and three in the field of glaucoma implants. Implant-related aspects were mainly found in connection with autonomy, freedom, identity, participation and justice, whereas little to no data was found with regards to ethical principles of privacy, safety or sustainability.

CONCLUSIONS

Empirical research on ethical aspects of implant use in everyday life is highly relevant, but marked by ambiguity and unclarity in the operationalization of ethical terms and contextualization. A transparent orientation framework for the exploration and acknowledgment of ethical aspects in "lived experiences" may contribute to the improvement of individual care, healthcare programs and research quality in this area. Ethics-sensitive care requires creating awareness for cultural and identity-related issues, promoting health literacy to strengthen patient autonomy as well as adjusting healthcare programs accordingly. More consideration needs to be given to sustainability issues in implant development and care according to an approach of ethics-by-design.

Patients' motivation to undergo transcatheter aortic valve replacement. A phenomenological hermeneutic study

BACKGROUND

Aortic stenosis is the most common valvular disease, and its prevalence is increasing due to the ageing population. Transcatheter aortic valve replacement (TAVR) is the recommended method when treating frail, older patients. Knowledge of what motivates older patients to undergo TAVR is important, in order to meet patients' expectations.

OBJECTIVE

The study aimed to explore the meaning of older patients' motivation to undergo TAVR.

DESIGN AND METHODS

The design was a qualitative study, analysed using a phenomenological hermeneutic approach. In-depth, semi-structured interviews with open-ended questions were conducted. Participants were selected from a specialist cardiology clinic in Sweden. Eighteen patients, six women and twelve men, aged 66-92, were recruited.

RESULTS

The analysis showed that patients who had agreed to undergo TAVR were deeply affected by their body's failure. Before the TAVR procedure, the participants were limited in their daily activities and experienced that their life was on hold. They experienced that they were barely existing. They were aware of their life-threatening condition and were forced to confront death. Yet despite an advanced age, they still had considerable zest for life. It was very important to them to remain independent in everyday life, and fear of becoming dependent had a strong impact on their motivations for undergoing TAVR.

CONCLUSION

Older patients' motivations to undergo TAVR are strongly influenced by their fear of being dependent on others and their zest for life. Health care professionals need to support these patients in setting realistic and personalised goals.

IMPLICATION FOR PRACTICE

Person-centered care actions could facilitate patients' involvement in the decision about TAVR and strenghten patients' beliefs in their own capabilities, before and after TAVR.

What matters most to patients with severe aortic stenosis when choosing treatment? Framing the conversation for shared decision making

Background

Guidelines recommend including the patient’s values and preferences when choosing treatment for severe aortic stenosis (sAS). However, little is known about what matters most to patients as they develop treatment preferences. Our objective was to identify, prioritize, and organize patient-reported goals and features of treatment for sAS.

Methods

This multi-center mixed-methods study conducted structured focus groups using the nominal group technique to identify patients’ most important treatment goals and features. Patients separately rated and grouped those items using card sorting techniques. Multidimensional scaling and hierarchical cluster analyses generated a cognitive map and clusters.

Results

51 adults with sAS and 3 caregivers with experience choosing treatment (age 36–92 years) were included. Participants were referred from multiple health centers across the U.S. and online. Eight nominal group meetings generated 32 unique treatment goals and 46 treatment features, which were grouped into 10 clusters of goals and 11 clusters of features. The most important clusters were: 1) trust in the healthcare team, 2) having good information about options, and 3) long-term outlook. Other clusters addressed the need for and urgency of treatment, being independent and active, overall health, quality of life, family and friends, recovery, homecare, and the process of decision-making.

Conclusions

These patient-reported items addressed the impact of the treatment decision on the lives of patients and their families from the time of decision-making through recovery, homecare, and beyond. Many attributes had not been previously reported for sAS. The goals and features that patients’ value, and the relative importance that they attach to them, differ from those reported in clinical trials and vary substantially from one individual to another. These findings are being used to design a shared decision-making tool to help patients and their clinicians choose a treatment that aligns with the patients’ priorities.

Health Literacy in the Context of Implant Care-Perspectives of (Prospective) Implant Wearers on Individual and Organisational Factors

The continuous development of medical implants offers various benefits for persons with chronic conditions but also challenges an individual’s, and the healthcare system’s, ability to deal with technical innovation. Accessing and understanding new information, navigating healthcare, and appraising the role of the implant in body perceptions and everyday life requires health literacy (HL) of those affected as well as an HL-responsive healthcare system. The interconnectedness of these aspects to ethically relevant values such as health, dependence, responsibility and self-determination reinforces the need to address HL in implant care. Following a qualitative approach, we conducted group discussions and a diary study among wearers of a cochlear, glaucoma or cardiovascular implant (or their parents). Data were analysed using the documentary method and grounded theory. The data reveal the perceptions of implant wearers regarding the implant on (1) the ability to handle technical and ambiguous information; (2) dependence and responsibility within the healthcare system; and (3) the ethical aspects of HL. Knowing more about the experiences and values of implant wearers is highly beneficial to develop HL from an ethical perspective. Respective interventions need to initially address ethically relevant values in counselling processes and implant care.

Patients' experiences of everyday living before and after transcatheter aortic valve implantation

BACKGROUND

Aortic stenosis (AS) is the most common valvular disease in western countries. Unless treated, it is associated with a poor prognosis. Surgical aortic valve replacement, the gold-standard approach, aims to increase survival and improve quality of life. In recent years, though, transcatheter aortic valve implantation (TAVI) has become the treatment of choice in elderly, high-risk patients who are denied open surgery. To date, however, little is known about their personal psychological experience after undergoing TAVI.

AIM

This study aimed to explore patients' experiences during everyday life before and after TAVI.

METHOD

Altogether, 14 elderly Swedish patients (9 women, 5 men), treated with TAVI, were interviewed between 2 and 6 months after the implantation. The interviews were analysed using qualitative content analysis.

RESULTS

Analysis of the participants' experiences was divided into two domains: before and after, that is, life with AS vs. life after TAVI. From these domains, four categories were derived: (1) adapting to the deteriorating self; (2) feeling disconnected; (3) reconstruction of self; and (4) processing disappointment.

CONCLUSIONS

Transcatheter aortic valve implantation involves not only adding years to life but also adding life to years. The urge to live an autonomous life in a social context with others is an important argument for undergoing a TAVI procedure. Despite severe illness and demanding rehabilitation, elderly TAVI patients have the ability to regain independence and rebuild their lives when they base their decision to undergo TAVI on personal goals. These findings might be helpful when implementing person-centred care.

Shared decision making in older patients with symptomatic severe aortic stenosis: a systematic review

This review provides an overview of the status of shared decision making (SDM) in older patients regarding treatment of symptomatic severe aortic stenosis (SSAS). The databases Embase, Medline Ovid, Cinahl and Cochrane Dare were searched for relevant studies from January 2002 to May 2018 regarding perspectives of professionals, patients and caregivers; aspects of decision making; type of decision making; application of the six domains of SDM; barriers to and facilitators of SDM. The systematic search yielded 1842 articles, 15 studies were included. Experiences of professionals and informal caregivers with SDM were scarcely found. Patient refusal was a frequently reported result of decision making, but often no insight was given into the decision process. Most studies investigated the 'decision' and 'option' domains of SDM, yet no study took all six domains into account. Problem analysis, personalised treatment aims, use of decision aids and integrating patient goals in decisions lacked in all studies. Barriers to and facilitators of SDM were 'individualised formal and informal information support' and 'patients' opportunity to use their own knowledge about their health condition and preferences for SDM'. In conclusion, SDM is not yet common practice in the decision making process of older patients with SSAS. Moreover, the six domains of SDM are not often applied in this process. More knowledge is needed about the implementation of SDM in the context of SSAS treatment and how to involve patients, professionals and informal caregivers.

Changes in the nutritional and activity status of elderly patients within 6 months of transcatheter aortic valve replacement: A mixed methods approach

AIM

Our aim was to explore changes in nutritional and activity status of patients within 6 months after transcatheter aortic valve replacement (TAVR) and factors affecting malnutrition post-TAVR in this cohort, and to gain understanding of their lifestyle considerations.

METHODS

Using a mixed methods approach, we conducted a prospective, longitudinal survey, consisting of interviews and a questionnaire, of 50 participants aged ≥70 years (mean age, 83 years; 58.0% female) undergoing TAVR. Mini Nutritional Assessment (MNA) and albumin level (to measure nutritional status) and Physical Component Summary (PCS) scores from the 36-item Short Form Health Survey (to measure activity status) were collected at pre-TAVR and 1 month and 6 months post-TAVR. Laboratory data and some index scores (e.g., the Clinical Frailty Scale [CFS] and the Mini-Mental State Examination [MMSE]) assessed before TAVR were collected from medical records as related factors.

RESULTS

Significant change was observed only in the MNA scores of participants who were assessed as malnourished at pre-TAVR, which improved, but did not reach normal nutritional status. Low-flow low-gradient aortic stenosis (odds ratio [OR]: 166.39, 95% confidence interval [CI]: 5.43-5094.43), higher CFS scores (OR: 2.58, 95% CI: 1.01-6.54), and lower MMSE scores (OR: 0.65, 95% CI: 0.43-0.99) were related to malnutrition post-TAVR. From interviews, three themes emerged: "balancing heart-healthy lifestyle and longstanding habits," "living with aging and disease" and "prospects for the rest of life."

CONCLUSIONS

Our results could be utilized to identify patients at risk of malnutrition post-TAVR, and to provide support with consideration of their lifestyle concerns.
