Physical therapist management of patients with ventricular assist devices: key considerations for the acute care physical therapist

Neurorehabilitation in a Pediatric Stroke Patient Supported on a CentriMag

Patients supported on ventricular assist devices (VADs) benefit from rehabilitation while awaiting heart transplantation to recover from surgery, prevent deconditioning, and, in most cases, optimize transplant candidacy. With bleeding and neurological dysfunction as the most common VAD complications, the importance of rehabilitation dramatically increases when a patient on a VAD also suffers from a neurological injury. The rehabilitation needs for cardiac conditioning and neurological reeducation are not the same. Patients with severe neurological deficits require intense rehabilitation that often includes base-of-support challenges, usage of bolsters and balls, partial weight-bearing treadmill training, and assumption of various body positions in prone, kneeling, or quadruped for neuromotor reeducation. However, some devices are more conducive to rehabilitation than others. For children supported by the CentriMag in particular, rehabilitation is challenged by short cannula tubing, an external motor, a large interface, and an intensive care unit (ICU) admission. We report a safe and successful physical therapy course of a pediatric stroke patient with a diagnosis of Ebstein's anomaly supported by a CentriMag right VAD (RVAD) while awaiting heart transplant in the ICU.

HFA of the ESC position paper on the management of LVAD-supported patients for the non-LVAD specialist healthcare provider Part 3: at the hospital and discharge

The growing population of left ventricular assist device (LVAD)‐supported patients increases the probability of an LVAD‐ supported patient hospitalized in the internal or surgical wards with certain expected device related, and patient‐device interaction complication as well as with any other comorbidities requiring hospitalization. In this third part of the trilogy on the management of LVAD‐supported patients for the non‐LVAD specialist healthcare provider, definitions and structured approach to the hospitalized LVAD‐supported patient are presented including blood pressure assessment, medical therapy of the LVAD supported patient, and challenges related to anaesthesia and non‐cardiac surgical interventions. Finally, important aspects to consider when discharging an LVAD patient home and palliative and end‐of‐life approaches are described.

Cardiac Rehabilitation in German Speaking Countries of Europe-Evidence-Based Guidelines from Germany, Austria and Switzerland LLKardReha-DACH-Part 2

Background: Scientific guidelines have been developed to update and harmonize exercise based cardiac rehabilitation (ebCR) in German speaking countries. Key recommendations for ebCR indications have recently been published in part 1 of this journal. The present part 2 updates the evidence with respect to contents and delivery of ebCR in clinical practice, focusing on exercise training (ET), psychological interventions (PI), patient education (PE). In addition, special patients’ groups and new developments, such as telemedical (Tele) or home-based ebCR, are discussed as well. Methods: Generation of evidence and search of literature have been described in part 1. Results: Well documented evidence confirms the prognostic significance of ET in patients with coronary artery disease. Positive clinical effects of ET are described in patients with congestive heart failure, heart valve surgery or intervention, adults with congenital heart disease, and peripheral arterial disease. Specific recommendations for risk stratification and adequate exercise prescription for continuous-, interval-, and strength training are given in detail. PI when added to ebCR did not show significant positive effects in general. There was a positive trend towards reduction in depressive symptoms for “distress management” and “lifestyle changes”. PE is able to increase patients’ knowledge and motivation, as well as behavior changes, regarding physical activity, dietary habits, and smoking cessation. The evidence for distinct ebCR programs in special patients’ groups is less clear. Studies on Tele-CR predominantly included low-risk patients. Hence, it is questionable, whether clinical results derived from studies in conventional ebCR may be transferred to Tele-CR. Conclusions: ET is the cornerstone of ebCR. Additional PI should be included, adjusted to the needs of the individual patient. PE is able to promote patients self-management, empowerment, and motivation. Diversity-sensitive structures should be established to interact with the needs of special patient groups and gender issues. Tele-CR should be further investigated as a valuable tool to implement ebCR more widely and effectively.

Characteristics, Therapeutic Needs, and Scope of Patients With a Continuous-Flow Left Ventricular Device Entering Cardiac Rehabilitation: A RETROSPECTIVE ANALYSIS

BACKGROUND

With an increasing number of left ventricular assist devices (LVADs) being implanted, the need for adequate cardiac rehabilitation (CR) regimens meeting the special needs of these patients arises. Only a few studies have reported experience gained on this topic. Structured CR strategies are poorly implemented. The aim was to evaluate the characteristics, therapeutic needs, and scope of LVAD patients at admission to CR within a greater cohort in order to identify their special CR needs.

METHODS

Retrospective single-center study; 69 LVAD patients (50.7 ± 13.6 y; 59 male; 48 HVAD; 21 HeartMate II) who completed first inpatient CR were included. Patient records were used to document relevant medical information (including the results of a 6-min walk test and a maximal isometric strength test for quadriceps femoral muscles in both legs) and the International Classification of Functioning, Disability and Health for classification of health and health-related domains.

RESULTS

Patient characteristics demonstrated a heterogeneous group: CR was started 44 ± 38.6 d after implantation; CR duration was 28 ± 9.7 d. Despite similar etiology, physical and psychological condition was diverse, although, overall a high degree of impairment was present, especially in the body function (79.7%) and activity and participation (95.7%) domains. The results demonstrated the need for a highly individualized approach in the somatic and also in the education, psychosocial, and social therapeutic regimes.

CONCLUSION

The results demonstrate a heterogeneous group with a high level of impairment and special needs in many CR domains. The development and evaluation of a special highly individualized approach of CR, which meets the special needs of these patients, is needed.

Human Factors and User Experience Issues with Ventricular Assist Device Wearable Components: A Systematic Review

Ventricular Assist Devices (VADs) provide continuous mechanical circulatory support during in- and out-of-hospital care. However, limitations of the external wearable components influence patient quality of life. There is insufficient understanding of the issues with such components that combines a holistic viewpoint from both human factors and user (including patient and caregiver) experience perspectives. This paper comprehensively details the issues with VAD wearable systems and proposes a way for human-centered design to bridge the gap, addressing such issues synergistically. Through the review the authors investigated: the user issues caused by wearable components of VADs, and how human factors issues correlate to the VAD user experience. A Boolean search ("ventricular assist" AND "human factors" AND "experience") for peer-reviewed studies published between 2008 and 2018 returned 338 titles, with 35 relevant studies selected using a PRISMA process for inclusion in cross-study analysis and synthesis. This paper provides design recommendations for the issues found in the literature. Four key focus areas to inform the future design of VAD wearable components were identified-'Power Supply', 'Wearability and Travel Freedom', 'The Female Experience' and 'Intuitive Handling'. Using design to drive innovation could result in VAD wearable components which better meet or exceed users' quality of life goals.

Inpatient Cardiac Rehabilitation of LVAD Patients-Updated Recommendations from the Working Group of the German Society for Prevention and Rehabilitation of Cardiovascular Diseases

Cardiac rehabilitation physicians are faced to an increasing number of heart failure patients supported by left ventricular assist devices (LVAD). Many of these patients have complex medical issues and prolonged hospitalizations and therefore need special cardiac rehabilitation strategies including psychological, social, and educational support which are actually poorly implemented.Cardiac rehabilitation with clear guidance and more evidence should be considered as an essential component of the patient care plan especially regarding the increasing number of destination patients and their long-term follow-up.In this article the working group for postimplant treatment and rehabilitation of LVAD patients of the German Society for Prevention and Rehabilitation of Cardiovascular Diseases has summarized and updated the recommendations for the cardiac rehabilitation of LVAD patients considering the latest literature.

Patient "Activation" of Patients Referred for Advanced Heart Failure Therapy

Advanced heart failure (HF) is a devastating chronic illness requiring complex treatment regimens and patient engagement. Having the information, motivation, and skills to live with a medical condition are conceptualized by the term, "activation." Patients referred for advanced HF therapy and their unpaid family caregiver were invited to participate in this study by completing the 10-item patient activation measure (PAM) questionnaire. Anxiety and depression were assessed via the hospital anxiety and depression scale. We compared activation, anxiety, and depression between those selected versus not selected for advanced HF therapy (left ventricular assist device or heart transplantation). We analyzed those who subsequently underwent advanced HF therapy in regards to activation and 1-year survival. There were 133 (68%) patients selected for therapy. Neither depression nor anxiety differed by selection status, but PAM levels did (p = 0.02). Those not selected for therapy were approximately 4 times more likely to have lower activation than those who were selected (8% vs 2%). Of the 133 selected patients, 110 (84%) subsequently underwent advanced HF therapy and 15 (14%) of those died within 1 year. Survival was independent of baseline anxiety (p = 0.92) and depression (p = 0.70), as well as patient and caregiver PAM (p = 0.50 and 0.77, respectively). In conclusion, patients with higher activation were more likely to be selected for advanced HF therapy.

Physical Therapist-Led Ambulatory Rehabilitation for Patients Receiving CentriMag Short-Term Ventricular Assist Device Support: Retrospective Case Series

BACKGROUND AND PURPOSE

Short-term ventricular assist device (VAD) support is used in the intensive care unit (ICU) to support individuals in end-stage heart failure prior to heart transplantation or implantation of a long-term left VAD. The literature investigating the feasibility, safety, and content of rehabilitation for this patient group is lacking. This report retrospectively describes the rehabilitation strategy, safety measures used, and nature of any adverse events and, therefore, the feasibility of this practice.

CASE SERIES DESCRIPTION

Ten individuals (80% male) admitted to the ICU in critical cardiogenic shock required support via a short-term VAD. A prerehabilitation risk assessment was used to reduce the risk of cannula dislodgement. The therapeutic strategy was a stepwise progression of exercises, mobilization, and ambulation.

OUTCOMES

Retrospective inspection of the case notes showed 330 rehabilitation sessions (X̅=33, SD=18.1, range=16-72) were performed and progressed to ambulation on 71 occasions (X̅=7.1, SD=7.7, range=1-27). Distance ambulated ranged from 7 to 1,200 m (X̅=157.7, SD=367.3). The Chelsea Critical Care Physical Assessment Tool (CPAx) score for 7 patients improved from a median of 0 (interquartile range=0-1) on day 1 to a median peak score of 39 (interquartile range=37-42). There were 8 episodes of minor adverse events (2.4% incidence rate), including 7 of transient low VAD flows. There were no major adverse events.

DISCUSSION

Early rehabilitation and ambulation of recipients of short-term VAD support was safe and feasible. Recipients demonstrated improvements in physical function (CPAx score) while the VAD was in situ.

[Rehabilitation standards for follow-up treatment and rehabilitation of patients with ventricular assist device (VAD)]

The increasing use of ventricular assist devices (VADs) in terminal heart failure patients provides new challenges to cardiac rehabilitation physicians. Structured cardiac rehabilitation strategies are still poorly implemented for this special patient group. Clear guidance and more evidence for optimal modalities are needed. Thereby, attention has to be paid to specific aspects, such as psychological and social support and education (e.g., device management, INR self-management, drive-line care, and medication).In Germany, the post-implant treatment and rehabilitation of VAD Patients working group was founded in 2012. This working group has developed clear recommendations for the rehabilitation of VAD patients according to the available literature. All facets of VAD patients' rehabilitation are covered. The present paper is unique in Europe and represents a milestone to overcome the heterogeneity of VAD patient rehabilitation.

Physical Therapy for a Child Poststroke With a Left Ventricular Assist Device

PURPOSE

To describe physical therapy (PT) examination and intervention during rehabilitation for a child poststroke with an implanted left ventricular assist device (LVAD).

KEY POINTS

A 10-year-old boy with a history of congenital heart disease awaiting heart transplant was admitted to a pediatric rehabilitation hospital with right hemiplegia, and an external, portable LVAD. This child participated in standard PT examination procedures and interventions with accommodations for the LVAD. Observation was used to evaluate exercise response because of inability to measure vital signs. At admission, impaired muscle tone, balance, and endurance contributed to limitations in functional mobility. By discharge, improvements were seen in all impairments and also in ambulation distance, speed, and independence.

CONCLUSION

This child awaiting heart transplant with an LVAD was able to tolerate intensive individualized PT. With monitoring and adjustments to the plan of care, he demonstrated improvements in functional mobility.
