The accepted use of left ventricular assist device (LVAD) technology as a good alternative for the treatment of patients with advanced heart failure together with the improved survival of patients on the device and the scarcity of donor hearts has significantly increased the population of LVAD supported patients. Device-related, and patient-device interaction complications impose a significant burden on the medical system exceeding the capacity of LVAD implanting centres. The probability of an LVAD supported patient presenting with medical emergency to a local ambulance team, emergency department medical team and internal or surgical wards in a non-LVAD implanting centre is increasing. The purpose of this paper is to supply the immediate tools needed by the non-LVAD specialized physician -ambulance clinicians, emergency ward physicians, general cardiologists, and internists -to comply with the medical needs of this fast-growing population of LVAD supported patients. The different issues discussed will follow the patient's pathway from the ambulance to the emergency department, and from the emergency department to the internal or surgical wards and eventually back to the general practitioner.
Aims
Exergaming is a new tool to increase physical activity. This study aimed to determine the effects of access to a home‐based exergame (Nintendo Wii) in patients with heart failure (HF) on exercise capacity, self‐reported physical activity and patient‐reported outcome measures.
Methods and results
We enrolled 605 HF patients in New York Heart Association functional class I–IV, independent of ejection fraction, in an international multicentre randomized controlled trial. Patients were randomized to exergame (intervention) or motivational support (control). The primary endpoint was change in submaximal aerobic exercise capacity as measured by the distance walked in 6 min (6MWT) between baseline and 3 months. Secondary endpoints included long‐term submaximal aerobic exercise capacity, muscle function, self‐reported physical activity, exercise motivation, exercise self‐efficacy at 3, 6 and 12 months. At baseline, patients on average walked 403 ± 142 m on the 6MWT. Patients in the exergame group walked further compared to controls at 3 months (454 ± 123 vs. 420 ± 127 m, P = 0.005), at 6 months (452 ± 123 vs. 426 ± 133 m, P = 0.015) and 12 months (456 ± 122 vs. 420 ± 135 m, P = 0.004). However, correcting for baseline 6MWT values by means of a linear mixed‐effects model revealed no main effect for the intervention on 6MWT. Small significant effects on muscle function were found. Statistically significant treatment effects were found for muscle function but after correction for baseline and confounders, only the treatment effect for the heel‐rise left at 6 months was significant (P < 0.05). No treatment effect was found for exercise motivation, exercise self‐efficacy, or self‐reported physical activity.
Conclusion
Exergaming was safe and feasible in patients with HF with different profiles in different health care systems, cultures and climates. However, it was not effective in improving outcomes on submaximal aerobic exercise capacity. Subgroup analysis did not identify specific subgroups benefiting from the intervention.

The improvement in left ventricular assist device (LVAD) technology and scarcity of donor hearts have increased dramatically the population of the LVAD-supported patients and the probability of those patients to present to the emergency department with expected and non-expected device-related and patient-device interaction complications. The ageing of the LVAD-supported patients, mainly those supported with the 'destination therapy' indication, increases the risk for those patients to suffer from other co-morbidities common in the older population. In this second part of the trilogy on the management of LVAD-supported patients for the non-LVAD specialist healthcare provider, definitions and structured approach to the
