The rotary blood pump (the HeartWare® Ventricular Assist Device) from HeartWare® (Medtronic) is an established left ventricular assist device and usually implanted via sternotomy. To reduce the invasiveness of the implant procedure and to optimize the position of the inflow cannula, we propose an alternative implant technique with an extrapericardial placement of the pump via left anterolateral minithoracotomy. However, the minimally invasive approach is not suitable in patients in need of an additional cardiac procedure or with thrombus formation in the left atrial appendix...

BACKGROUND: The balance of oxygen delivery and consumption is essential in patients who are critically ill. Mixed venous oxygen saturation (Sv̄O2 ) is a standard method to evaluate oxygen delivery and consumption during anesthesia. However, Sv̄O2 is monitored through a pulmonary artery catheter, which is invasive. Regional cerebral oxygenation (rScO2 ) reflects oxygen saturation in a small region of the frontal lobes and is monitored noninvasively through near-infrared spectroscopy...

BACKGROUND: Transapical off-pump mitral valve (MV) repair is a novel minimally-invasive surgical technique, allowing to correct mitral regurgitation (MR) caused by chordae tendineae rupture. While numerical simulation of the MV structure has proven to be useful to evaluate the effects of the MV surgical repair techniques, no numerical simulation studies on the outcomes of transapical MV repair have been done up to now. OBJECTIVE: The purpose of this study is to evaluate the transapical MV repair using finite element modeling and to determine the effect of the neochordal length on the function of the prolapsing MV...
