Samura T, et al. - In the present study, researchers investigated the risk factors for stroke in acute phase after left ventricular assist device (LVAD) implantation. They identified 158 consecutive patients (mean age, 43 ± 14 years; 34% women) who underwent continuous-flow LVAD (50 HeartMateII, 38 DuraHeart, 33 Jarvik2000, 23 EVAHEART, 14 HeartWare) implantation at their institution between October 2005 and December 2016. Patients displaying perioperative lower cardiac output and higher lactate dehydrogenase (LDH) level were noted to develop stroke in the acute phase after LVAD implantation. Maintenance of sufficient LVAD flow was suggested as significant in the prevention of stroke which may be related to subclinical pump thrombosis.
