Background: Intractable bleeding from the apical cannulation site of a left ventricular assist device (LVAD) is a dreaded complication. Case report: A 52-year-old male suffering from dilative cardiomyopathy (DCM) with fixed pulmonary hypertension underwent reoperative LVAD implantation after previous mitral valve surgery. The patient underwent three rethoracotomies for bleeding from the apex cannulation site without achieving hemostasis. Conventional techniques and application of fibrin sealants and polymeric sealing devices did not fix the problem. The bleeding stopped after application of the EVARREST® Fibrin Sealant Patch (FSP), and he needed no further transfusions. Conclusion: This patch might become a useful tool for intractable bleeding problems in LVAD surgery.

Mitral valve regurgitation (MR) causes blood to flow in two directions during contraction of the left ventricle (LV), that is, forward into the aorta and backward into the left atrium (LA). In aortic valve regurgitation (AR), leakage occurs from the aorta into the LV during diastole. Our objective is to analyze the contribution of a left ventricular assist device (LVAD) to MR and AR for the following two different cannulation sites: from the LA to the aorta (LAAO) and from the LV to the aorta (LVAO). Using a computational method, we simulated three ventricular conditions (normal [HF without valvular regurgitation], 5% MR, and 5% AR) in three groups (control [no LVAD], LAAO, and LVAO). The results showed that LVAD with LAAO cannulation is appropriate for recovery of the MR heart, and the LVAD with LVAO cannulation is appropriate for treating the AR heart.
