title: [Right ventricular infarction following acute inferior myocardial infarction confirmed by dual isotope single photon emission computed tomography (SPECT) of [99mTc] pyrophosphate and [201Tl] chloride].
abstract: A 56-year-old man, complaining of severe substernal chest pain, was admitted. In this patient, right ventricular infarction following by acute inferior myocardial infarction was suggested by serial enzymes, electrocardiogram, echocardiogram, and hemodynamic data, but it was not confirmed. A dual isotope SPECT with 99mTc-pyrophosphate and 201Tl-Cl was performed and color-coded tomograms were obtained. It showed a characteristic image of right ventricular infarction, especially in the short axis view right ventricular infarction looked like shape of a tongue which protruded from left ventricle. We concluded that though the diagnosis of right ventricular infarction is difficult, a dual isotope SPECT is a useful method because it shows a characteristic image.
