Summary
This summary is machine-generated.

Right ventricular longitudinal strain (RVLS) assessed by feature tracking more accurately reflects right ventricular (RV) contractility in pulmonary arterial hypertension (PAH) than RV ejection fraction (RVEF). This method offers a better estimation of RV function in PAH.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Pulmonary Hypertension Research

Background:

  • Right ventricular (RV) function is crucial for prognosis in pulmonary arterial hypertension (PAH).
  • Cardiovascular magnetic resonance (CMR) is used to assess RV function.
  • The accuracy of RV longitudinal strain (RVLS) via feature tracking for assessing RV contractility remains unclear.

Purpose of the Study:

  • To compare feature-tracking RVLS and RV ejection fraction (RVEF) against direct measures of RV muscle contractility.
  • To determine if RVLS is a more accurate indicator of RV contractility than RVEF in a rat model of PAH.

Main Methods:

  • A monocrotaline (MCT) rat model of PAH was established.
  • Cardiac MRI was performed to acquire RV pressure and cine images.
  • RV trabeculae were dissected, stimulated, and force production (maximum dF/dt) was measured.

Main Results:

  • MCT-rats exhibited elevated RV systolic pressure and reduced RVLS compared to controls.
  • RVEF was preserved in half of the MCT-rats, masking underlying contractile dysfunction.
  • RVLS demonstrated a linear correlation with maximum dF/dt, indicating better reflection of contractility.

Conclusions:

  • Feature-tracking RVLS provides a more accurate assessment of RV contractile properties in PAH rats than RVEF.
  • RVLS is a valuable tool for estimating RV function in the context of PAH.
