Case Reports
Clinical Course of Three Postoperative Symptomatic COVID-19 Cases in Patients After Lung Lobectomy.
The novel coronavirus disease 2019 is a highly contagious viral infection caused by the severe acute respiratory syndrome coronavirus 2 virus. Its rapid spread and severe clinical presentation influence patient management in all specialties including thoracic surgery. We report 3 cases of coronavirus disease 2019 occurring in patients shortly after thoracotomy and thoracoscopy procedures, illustrating the imminent threat of severe acute respiratory syndrome coronavirus 2 infection for thoracic surgery patients.

Comparative Study
Intraaortic Balloon Pump vs Peripheral Ventricular Assist Device Use in the United States.
The objective of this study was to characterize practical use trends and outcomes for intraaortic balloon pump (IABP) and percutaneous left ventricular assist device (pVAD) use in cardiogenic shock at a national level. ⋯ Over the study period, the rate of pVAD use for cardiogenic shock significantly increased. Compared with IABP, pVAD use was associated with increased mortality, higher costs, and several AEs. Multi-institutional clinical trials with rigorous inclusion criteria are warranted to evaluate the clinical utility of pVADs in the modern era.

Randomized Controlled Trial Comparative Study
Dextran- Versus Crystalloid-Based Prime in Cardiac Surgery: A Prospective Randomized Pilot Study.
The optimum priming fluid for the cardiopulmonary bypass (CPB) circuit is still debated. We compared a new hyperoncotic priming solution containing dextran 40, which has an electrolyte composition that mimics extracellular fluid, with a standard crystalloid-based prime. ⋯ Our results suggest that a hyperoncotic dextran-based priming solution preserves intraoperative colloid oncotic pressure compared with crystalloid prime. Larger studies with clinically valid end points are necessary to evaluate hyperoncotic prime solutions further.

Acute pulmonary embolism is an uncharacteristic presentation in patients with coronavirus 2019 (COVID-19). Here we describe the case of a young woman presenting with severe pulmonary embolism, without any associated symptoms of infections. A clot in a patent foramen ovale was noted. ⋯ She was put on extracorporeal life support and tested positive for COVID-19. She died of multiorgan failure on day 10. COVID-19 may have a thrombogenic effect, and it may need to be considered in cases of pulmonary embolism and in the absence of any obvious risk factor.
