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.

The authors make a brief overview of tricuspid regurgitation associated with congenital heart defects, including morphology, incidence and echocardiographic evaluation.  The status quo of medical and surgical managements and outcomes are also comprehensively reviewed.

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.

The previous randomized study of minimally invasive esophagectomy vs open esophagectomy (TIME trial) conducted in the Netherlands demonstrated reduced pulmonary complications and LOS with MIE.  Compared to the benefits of MIE in those selected high volume centers, national use of MIE was associated with increased overall complications, increased pulmonary complications, and increased reoperation rates.

This original article retrospectively analyzed the outcome of 200 patients after implantation of HeartMate 3 and HeartWare LVAD respectively. The baseline characteristics of both groups, containing 100 patients each, were comparable, despite a higher percentage of INTERMACS I and II patients implanted with the HeartWare device. While the overall survival was not different, patients receiving HeartWare LVAD had more intracranial bleeding, while the total fraction of patients with cerebrovascular accidents was not different. The authors conclude that the devices show a different complication profile, but comparable intermediate survival.
