RV Free Wall Strain plays a vital role in the early detection of right ventricular dysfunction, often missed by conventional imaging methods. Unlike global RV function metrics, which can be influenced by left ventricular motion or loading conditions, this strain technique isolates the free wall of the right ventricle to deliver a more accurate and specific evaluation. It is especially useful in patients with pulmonary hypertension, chronic lung disease, heart failure, congenital heart disorders, and those undergoing chemotherapy or cardiac surgery.

By capturing subtle contractile impairments before clinical symptoms appear, RV Free Wall Strain helps guide prognosis, risk stratification, and treatment planning. In critical care and heart transplant patients, it can be a key predictor of outcomes. Due to its high sensitivity and reproducibility, RV Free Wall Strain is becoming an integral part of comprehensive echocardiographic assessments in modern cardiology practice.
