Covid-19 Induced Right Ventricular Failure And Right Ventricular Assist Device Support, Marvin Slepian M.D.
Covid-19 Induced Right Ventricular Failure And Right Ventricular Assist Device Support, Marvin Slepian M.D.
Journal of Shock and Hemodynamics
COVID-19, while primarily recognized for its pulmonary and systemic manifestations, afflicts the cardiovascular system through various abnormalities. Notably, right ventricular (RV) involvement leading to dysfunction and failure is a manifestation seen in up to 20% of severe COVID patients. RV severity correlates with overall COVID severity, serving as a prognostic marker. Data review reveals that RV failure was largely underdiagnosed, particularly early on in the pandemic. The therapy approach for RV failure in patients with COVID should focus on supporting overall RV perfusion pressure, maintaining sinus rhythm, optimizing RV loading conditions and contractility, and addressing anticoagulation and thrombus-related conditions. Beyond …
Reperfusion Injury In Acute Myocardial Infarction Shock- Role Of Mechanical Circulatory Support Devices, Finn Gustafsson
Reperfusion Injury In Acute Myocardial Infarction Shock- Role Of Mechanical Circulatory Support Devices, Finn Gustafsson
Journal of Shock and Hemodynamics
The efficacy of mechanical circulatory support in acute myocardial infarction is dependent upon the size of the infarct. If applied early, mechanical support to reduce reperfusion injury appears to be effective in reducing infarct size in animal studies. The optimal timing of reperfusion is uncertain and requires further investigation. Efficient unloading appears to be essential in increasing the efficacy of the type of mechanical support and may favor one over another.
Systemic Inflammatory Response Syndrome And Mechanical Circulatory Support Devices, Mircea R. Mihu, Aly El-Banayosy
Systemic Inflammatory Response Syndrome And Mechanical Circulatory Support Devices, Mircea R. Mihu, Aly El-Banayosy
Journal of Shock and Hemodynamics
Systemic inflammatory response syndrome is an increased inflammatory state affecting the whole body. Mechanical circulatory support (MCS) is a temporary or permanent form of extracorporeal support that may have an associated complication of an exacerbated inflammatory response to the extracorporeal circuit. This brief review will focus on understanding the complex pathophysiology of inflammatory response to MCS, factors that influence the extent of the inflammatory response, the inflammatory response and outcomes as well as potential therapeutic strategies.
