Dynamic right ventricular outflow tract obstruction is rare in the cardiac surgical population. Significant obstruction developing in the perioperative period can contribute to systemic hemodynamic instability. ⋯ Both patients had systemic hypotension which improved once ventricular pacing was discontinued. We discuss the recognition of right ventricular outflow tract obstruction as a contributing factor to hemodynamic instability, as well as the importance of identifying the underlying cause such as to institute appropriate management in these patients.

Morbidity and mortality associated with the pandemic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (coronavirus disease 2019 [COVID-19]) are not only due to acute respiratory distress syndrome but also related to multiorgan involvement and dysfunction. In this report, we present a critically ill patient with severe COVID-19 pneumonia, during which he required extracorporeal membrane oxygenation and suffered from multiple complications. Bedside sonography became an important tool to manage the patient by adapting artificial ventilation parameters and played a key role in the diagnosis of thrombotic events and the monitoring of subarachnoid hemorrhage that unexpectedly complicated the case.

Intraoperative Hemostatic Management of a Cardiohepatic Transplant With Rotational Thromboelastometry: A Case Report.
Cardiohepatic transplantation represents a double hemostatic challenge. Given the absence of specific guidelines and current evidence, we designed a 5-step approach based on rotational thromboelastometry (ROTEM). A 60-year-old male patient with cirrhosis and myocarditis underwent a 9-hour transplantation. ⋯ During liver transplant, only hemoglobin optimization was necessary. In conclusion, hemostatic management protocols for cardiohepatic transplants should consider the specific coagulopathy mechanisms underlying each surgical phase. Because whole blood testing is essential for their diagnosis, we recommend using ROTEM for optimal coagulation management.
