Abstract The HeartMate II (HMII) left ventricular assist device can be exchanged to HeartMate 3 (HM3) to reduce the risk of device thrombosis and stroke. However, data of this procedure are still limited. We reviewed early and mid-term outcomes of 9 patients who received a HMII to HM3 exchange at our institution. The median age of the cohort was 58 years [interquartile range (IQR) 53–61], and 7 (78%) patients were men. The median duration of HMII support was 608 days (IQR 493–1116). Indications for device exchange include device thrombosis (n = 8.89%) and driveline injury (n = 1.11%). Procedures were performed through a lateral thoracotomy in all patients. The median cardiopulmonary bypass time was 117 min (IQR 97–133). In-hospital mortality was 0%. One patient required repositioning of the HM3 pump through full sternotomy due to inflow malposition. During 486 days (IQR 235–712) of follow-up, 3 patients (33%) developed late HMII pump pocket infection after discharge. Five patients had a successful heart transplant and 1 patient died due to unknown reason. HMII to HM3 exchange can be performed via lateral thoracotomy. However, there is a risk of inflow malposition and previous pump pocket infection.

Preliminary Study

Left ventricular assist systems are being developed for eventual long term or permanent implantation as an alternative to heart transplantation in patients unsuitable for or denied the transplant option. Evaluation of the effects of these devices upon normal physiology is required. A preliminary study was conducted to evaluate the morphology of aortic tissue from calves implanted with a pneumatic Left Ventricular Assist device-LVAD. Two 3 month old heifer calves (calf 1 and calf 2) were electively explanted after 128 days and 47 days respectively. Descending thoracic aortic tissue from both animals was removed immediately post mortem and placed into karnovsky’s fixative. The tissue was subsequently processed for transmission electron microscopy (TEM). Some aortic tissue was fixed in neutral buffered formalin and processed for routine light microscopy.
