Right ventricular infarction: two-dimensional echocardiographic evaluation.

B I Jugdutt, B A Sussex, C A Sivaram

    American Heart Journal

    Summary

    Two-dimensional echocardiography (2DE) revealed significant abnormal wall motion in the right ventricle (RV) of patients with predominant right ventricular infarction (RVMI). This diagnostic tool confirmed greater RV involvement compared to the left ventricle (LV).

    Area of Science:

    • Cardiology
    • Diagnostic Imaging
    • Echocardiography

    Background:

    • Right ventricular infarction (RVMI) is a critical condition often associated with left ventricular (LV) involvement.
    • Accurate assessment of RV and LV dysfunction is crucial for understanding RVMI pathophysiology and patient outcomes.
    • Two-dimensional echocardiography (2DE) is a primary imaging modality for evaluating cardiac structure and function.

    Purpose of the Study:

    • To assess the utility of 2DE in evaluating the extent of abnormal wall motion (AWM) in patients with predominant RVMI.
    • To compare the topographic extent of AWM between the right ventricle (RV) and left ventricle (LV).
    • To correlate echocardiographic findings with biochemical markers and identify mechanical complications.

    Main Methods:

    Related Experiment Videos

  • Seventeen patients with predominant RVMI underwent 2DE examinations.
  • Abnormal wall motion (akinesis and dyskinesis) in RV, interventricular septum, and LV was quantified.
  • Correlation analysis was performed between AWM extent and peak creatine phosphokinase levels.

    • Main Results:

    • All patients exhibited AWM in the inferior RV, interventricular septum, and inferior LV.
    • The topographic extent of AWM was significantly greater in the RV (58%) compared to the LV (36%) (p < 0.05).
    • Peak creatine phosphokinase levels correlated significantly with the extent of LV AWM (r = 0.79) and total RV + LV AWM (r = 0.75).

    Conclusions:

    • 2DE is a valuable diagnostic tool for assessing RV and LV AWM in RVMI.
    • Findings confirm predominant RV involvement in patients presenting with RVMI.
    • Serial 2DE studies can detect mechanical complications and mural thrombi.
