First transit and equilibrium radionuclide angiography in patients with inferior transmural myocardial infarction: criteria for the diagnosis of associated hemodynamically significant right ventricular infarction

MR Starling, LJ Dell'Italia, TK Chaudhuri, BL Boros, and RA O'Rourke

To define radionuclide criteria for identifying hemodynamically significant right ventricular infarction, 33 consecutive men with inferior transmural infarction were evaluated prospectively by right heart catheterization and first transit and equilibrium radionuclide angiography within 36 hours of the onset of symptoms. Hemodynamically significant right ventricular infarction was present in 6 of the 33 patients (Group I); the remaining 27 patients did not demonstrate the hemodynamics characteristic of right ventricular infarction (Group II). A right ventricular ejection fraction of less than 40% separated Group I and Group II patients by equilibrium (p = 0.003) but not by first transit (p = NS) radionuclide angiography. However, a right ventricular ejection fraction of less than 35% separated Group I and II patients by both techniques (p = 0.02 and p = 0.005, respectively). The presence of a right ventricular regional wall motion abnormality on either first transit or equilibrium radionuclide angiograms separated Group I and II patients (p less than 0.001). The combination of both a right ventricular ejection fraction of less than 40% and a regional wall motion abnormality separated Group I and II patients using either equilibrium (p less than 0.001) or first transit (p = 0.02) radionuclide angiography. It is concluded that in patients with acute inferior transmural myocardial infarction, a right ventricular regional wall motion abnormality alone or in combination with a right ventricular ejection fraction of less than 40% by either first transit or equilibrium radionuclide angiography is a useful criterion for establishing the presence of hemodynamically significant right ventricular infarction, while its absence argues against the diagnosis of right ventricular infarction.
