Technology and technique for left ventricular assist device optimization: A Bi-Tech solution

Background We investigated the synergistic effect of the new cone-bearing design of Jarvik 2000 (Jarvik Heart Inc., NY) together with a minimally-invasive approach to outcomes of LVAD patients. Methods We retrospectively reviewed all patients from 5 institutions involved in the Jarvik 2000 Italian Registry, from October 2008 to October 2016. Patients were divided into three groups according to pump design and implantation technique: pin-bearing design and conventional approach (Group 1); cone-bearing and conventional approach (Group 2); cone-bearing and minimally-invasive implantation (Group 3). Results A total of 150 adult patients with end-stage heart failure were enrolled: 26 subjects in Group 1, 74 in Group 2, and 50 in Group 3. Nineteen patients (73%) in Group 1, 51 (69%) in Group 2, and 36 (72%) in Group 3 were discharged. During follow-up, 22 patients underwent transplantation, while in 3 patients the LVAD was explanted. The overall 1-year survival was 58 +/- 10%, 64 +/- 6%, and 74% +/- 7% in Groups 1, 2, and 3, respectively (p = 0.034). The competing-risks-adjusted cumulative incidence rate for adverse events was 42.1 [27-62.7] per 100 patient-years in Group 1, 35.4 [25.3-48.2] in Group 2, and 22.1 [12.4-36.4] in Group 3 (p = 0.046 for Group 1 vs. 3). Conclusions The association of the modern cone-bearing configuration of Jarvik 2000 and minimally invasive surgery improved survival and minimized the risk for cardiovascular events, as a result of combining technology and technique

Left subclavian artery as an alternative site for left ventricular assist device outflow graft in challenging situations

Left ventricular assist device (LVAD) has emerged as an effective surgical therapy for end-stage heart failure. In an attempt to reduce invasiveness and avoid difficult sternal re-entries, alternative surgical approaches have been adopted. In particular, when the thoracic aorta is severely diseased or difficult to expose, subclavian arteries could serve as site for outflow graft anastomosis. However, major concerns regarding the utilization of subclavian arteries are the small caliber of these vessels that could lead to inadequate LVAD flow, arm complications related to excessive blood flow, and possible outflow graft compression. In the present case series, we describe an innovative technique for LVAD implantation, in which the left subclavian artery was employed as an outflow graft anastomosis site, and the left ventricular apex was approached through a mini-thoracotomy. Technical issues were considered to prevent possible complications: the adequacy of left subclavian artery diameter, the banding of the artery distal to the anastomosis site to limit left arm overflow, and the outflow graft covering with a reinforced vascular graft to avoid any external compression. During follow-up, the technique reported was found to be effective in ensuring good LVAD function and flow, and no complications related to the procedure were reported

EAACI Guidelines on the effective transition of adolescents and young adults with allergy and asthma

Adolescent and young adult (AYA) patients need additional support while they experience the challenges associated with their age. They need specific training to learn the knowledge and skills required to confidently self-manage their allergies and/or asthma. Transitional care is a complex process which should address the psychological, medical, educational and vocational needs of AYA in the developmentally appropriate way. The European Academy of Allergy and Clinical Immunology has developed a clinical practice guideline to provide evidence-based recommendations for healthcare professionals to support the transitional care of AYA with allergy and/or asthma. This guideline was developed by a multi-disciplinary working panel of experts and patient representatives based on two recent systematic reviews. It sets out a series of general recommendations on operating a clinical service for AYA, which include: (i) starting transition early (11-13 years), (ii) using a structured, multidisciplinary approach, (iii) ensuring AYA fully understand their condition and have resources they can access, (iv) active monitoring of adherence and (v) discussing any implications for further education and work. Specific allergy and asthma transition recommendations include (i) simplifying medication regimes and using reminders; (ii) focusing on areas where AYA are not confident and involving peers in training AYA patients; (iii) identifying and managing psychological and socioeconomic issues impacting disease control and quality of life; (iv) enrolling the family in assisting AYA to undertake self-management and (v) encouraging AYA to let their friends know about their allergies and asthma. These recommendations may need to be adapted to fit into national healthcare systems
