[Single-photon emission computed tomography in diagnosis of left ventricular post-infarction aneurysm].
2004
AIM: To assess value of single-photon emission computed tomography with (99m)Tc-sestamibi ((99m)Tc MIBI SPECT) for detection of post-infarction left ventricular aneurysm in patients with coronary artery disease. MATERIAL: Fifty nine patients were operated upon because of coronary heart disease. In 27 patients with post-infarction left ventricular aneurysm modified Dor operation (aneurysmectomy with endoventricular circular patch plasty reconstruction) was performed. In 24 patients with extended cardiosclerosis direct myocardial revascularization was conducted. RESULTS AND CONCLUSION: Comparison of (99m)Tc MIBI SPECT data obtained at rest and during dobutamine stress test revealed some diagnostic features characteristic of patients with left ventricular post-infarction aneurysm. Quantitative and qualitative assessment of viability of myocardium in basal and "borderline" zones influenced not only the volume of revascularization, it was important for preliminary determination of post-infarction left ventricular aneurysm resection level, selection of type of plasty, prognostication of complications in immediate and remote postoperative periods.
