This original article retrospectively analyzed the outcome of 671 patients undergoing LVAD implantation within the French multicenter ASSIST-ICD registry. While half of the patients were in cardiogenic shock and more than 20% of patients were on ECLS prior to implantation, the survival at five years is around 50%. This reflects the real world and all-comers nature of this registry and therefore provides a frank picture of LVAD outcomes in France between 2007 and 2017. Looking at their results, the authors recommend earlier referral of heart failure patients to lower the 50% rate of patients being in cardiogenic shock prior to implantation and thereby improving result of LVAD therapy in France.

A small histopathological study of SARS and influenza autopsies compared to rejected for transplantation lungs. There is some speculation on the popular procoagulopathic nature of the panvirus, based on expression of angiotensin converting enzyme 2.There might be a collateral stimulus for lung preservation in organ retrieval.

Researchers from the UK reported a novel polymeric heart valve, PoliValve, which is made entirely from styrenic block copolymers.
The unique feature of PoliValve is that it is made of a self-assembling polymer with a microstructure conferring mechanical anisotropy analogous to that of natural valve tissue. Its prototype substantially exceeds ISO standards for in-vitro testing and shows encouraging preliminary results in acute in-vivo feasibility/safety testing in sheep without anticoagulation. Postmortem confirmed intact structure of the PHV with no evidence of any acute valvular clot/thrombus. Its durability exceeded 1.2 billion cycles in accelerated in-vitro tests, equivalent to 30 patient years.
These results show that PoliValve is a promising alternative to traditional biological and mechanical valve prostheses, which lasts up to 30 years and does not need anticoagulation.
