Prognostic Value of Right Ventricular-pulmonary Arterial Coupling Assessed by Echocardiography in Septic Patients

Sepsis and septic shock are common clinical conditions, representing a significant healthcare challenge due to their high mortality rates and increasing incidence. Sepsis-induced cardiomyopathy is a frequent complication, occurring in up to 44% of septic patients. This condition is associated with a two- to three-fold increase in mortality. Although sepsis-induced cardiomyopathy is typically diagnosed via echocardiography to assess left ventricular systolic function, both ventricles may be affected. Several studies have demonstrated that right ventricular dysfunction (RVD)/ right ventricular failure (RVF) was prevalent in sepsis and septic shock, with significant implications for prognosis and mortality. The right ventricle (RV) has a distinct anatomical structure and function compared to the left ventricle, characterized by its high sensitivity to afterload variations. Even minor incre
