Normalisation of haemodynamics in patients with end-stage heart failure with continuous-flow left ventricular assist device therapy.
New generation continuous-flow left ventricular assist devices (LVADs) utilise centrifugal pumps. Data concerning their effect on patient haemodynamics, ventricular function and tissue perfusion is limited. We aimed to document these parameters following HeartWare centrifugal continuous-flow LVAD (HVAD) implantation and to assess the impact of post-operative right heart failure (RHF). ⋯ HVAD support improves haemodynamics, LV dimensions and renal function. Following implantation with a centrifugal continuous-flow LVAD, RHF remains a significant risk with a tendency to worse outcomes in the short to medium term.

Case ReportsPost-traumatic injury of the brachiocephalic artery: on-pump beating heart repair.
We report the case of 54 year-old man who presented with an injury of the brachiocephalic artery secondary to a violent blunt chest trauma. The patient underwent urgent open surgical repair. The procedure was achieved on on-pump beating heart approach. The subsequent course was uneventful.

Review Meta Analysis Comparative StudyCoronary artery bypass grafting versus combined coronary artery bypass grafting and mitral valve repair in treating ischaemic mitral regurgitation: a meta-analysis.
Ischaemic mitral regurgitation (IMR) is commonly manifested after coronary artery disease, but it is still controversial as to whether coronary artery bypass grafting (CABG) alone improves postoperative outcome. ⋯ Compared with CABG alone, patients who underwent combined CABG and MVR procedures showed a greater improvement in postoperative MR grade, but in terms of in-hospital mortality, MR grade improvement rate, postoperative mean NYHA functional class and five-year survival, adding MVR to CABG surgery lacks evidence to show its superiority.

Case ReportsAwake extracorporeal membrane oxygenation (ECMO) as bridge to recovery after left main coronary artery occlusion: a promising concept of haemodynamic support in cardiogenic shock.
Cardiogenic shock following acute myocardial infarction is associated with high mortality rate. Different management concepts including fluid management, inotropic support, intra aortic balloon counterpulsation (IABP) and extracorporeal membrane oxygenation (ECMO) mainly in mechanically ventilated patients have been used as cornerstones of management. ⋯ Few reports suggested that ECMO when performed under circumvention of mechanical ventilation, may offer some survival benefits. We herein present our experience with the use of veno-arterial ECMO as bridge to recovery in an awake and spontaneously breathing patient after left main coronary artery occlusion complicated by cardiogenic shock.
