“…11 However, the HeartWare system does show a problem coming along with most biventricular assists: because the pulmonary vascular resistance is much smaller than the total peripheral resistance, it is necessary to narrow the RVAD outflow conduit from 10 to 5 mm to avoid overloading the pulmonary circulation. 12,13 In addition, the biventricular HeartWare needs 4 batteries and 2 controllers simultaneously, which increases the inconvenience for the patient. 12 Therefore, there are several reasons why we preferred the Jarvik 2000 system.…”

Objectives: Organ shortages and increased numbers of nontransplant older patients have necessitated a search for alternatives to heart transplants. The Jarvik 2000 assist device (Jarvik Heart, Inc., Manhattan, NY, USA), as a small long-term axial flow pump, offers many advantages, such as retroauricular power supply, which minimizes driveline infection risks. When implanted biventricularly, the device may offer support for patients with biventricular heart failure, especially for nontransplant patients as a destination therapy. Materials and Methods: We implanted biventricular

“…After completion of proximal anastomosis at the sinotubular junction level, the cross-clamp was released. Under the restored beating heart, an apical ring was sewn to the left ventricular apex with a running polypropylene suture and a HeartWare LVAD (Heartware International) was placed in the typical configuration [2]. The outflow graft was anastomosed to the aortic graft in an end-to-side manner.…”

Coexistence of aortic disease is an uncommon finding in end-stage heart failure patients requiring left ventricular assist device (LVAD) placement. A 38-year-old man with non-ischemic dilated cardiomyopathy was admitted in stage D heart failure. Preoperative computed tomography demonstrated multiple saccular aneurysms of the ascending aorta and sinus of valsalva. We successfully performed complex aortic surgery and the implantation of a continuous-flow LVAD (HeartWare HVAD) (HeartWare International, Framingham, MA). The postoperative course was uneventful. The patient is currently listed for heart transplantation.

“…91, 92 These can be treated with RVAD or by switching to biventricular support. 89, 93 In addition to the 2 earlier devices, the HeartWare HVAD 94 and HeartMate II 95 have been used for long-term support of the RV. The TAH are, of course, another option.…”
