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.

Extracorporeal membrane oxygenation for very high-risk transcatheter aortic valve implantation.
Transcatheter aortic valve implantation (TAVI) can cause profound haemodynamic perturbation in the peri-operative period. Veno-arterial extracorporeal membrane oxygenation (ECMO) can be used to provide cardiorespiratory support during this time, either prophylactically or emergently. ⋯ Instituting prophylactic ECMO in selected very high-risk patients may help avoid consequences of intra-operative complications and the need for emergent rescue ECMO.

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.
