Recently the use of a new radioactive agent with physical and biological properties more favorable than those of thallium 201, methoxy-isobutyl- isonitryl (MIBI) labeled with technetium 99m (Tc 99m), has permitted simultaneous performance of perfusion and function studies in ischemic cardiopathy. Transesophageal atrial pacing (TAP) technique has evolved as an alternative provocative test of ischemia. The authors compared the capability of Tc 99m-MIBI myocardial scintigraphy, combined with TAP, with that of Tc 99m-MIBI, combined with maximal stress test, in the diagnosis of ischemic cardiopathy. They studied 11 patients with a clinical history of angina pectoris. Myocardial scintigraphy was performed at rest, after stress test, and after TAP. Finally, all the patients underwent coronary angiography. The analysis of myocardial perfusion images on both Tc 99m-MIBI associated with TAP and with stress demonstrated, in 165 myocardial segments examined: 143 normal, 20 reversible defects, 2 irreversible defects. The concordance of localization between coronographic data and scintigraphic reversible and irreversible defects was 85%. In conclusion TAP proves to be a valid and sensitive provocative test of ischemia when combined with myocardial scintigraphy and with Tc 99m-MIBI.
