In critical care ultrasound, RV strain in PE refers to the acute right ventricular dysfunction caused by increased afterload due to a pulmonary embolism (PE). This crucial finding indicates the right ventricle is struggling to pump blood against elevated pulmonary pressures, leading to dilation and impaired contractility. Early identification through bedside ultrasound is vital for guiding management and improving patient outcomes in acute PE.
Recognizing RV strain in PE via ultrasound, often seen as RV dilation and septal bowing, allows for timely intervention in critically ill patients. This assessment is central to risk stratification in PE, helping clinicians determine the severity of the embolus and the need for advanced therapies like thrombolysis.
