Abstract: Objective To evaluate the use of gated SPECT in patients with hypertrophic obstructive cardiomyopathy (HOCM) and the effects of percutaneous transluminal septal myocardial ablation (PTSMA) on myocardial perfusion.Methods 99 Tcm-methoxyisobutylisonitrile (MIBI) and 18F-fluorodeoxyglucose (FDG) images were performed in 31 HOCM patients before PFSMA and in 15 patients 3-7 d after PTSMA.The images in different left ventricular segments were analysed by using scores.Results In 99Tcm-MIBI images, uptake decreased at the septal regions in 12 HOCM patients (80.0%, 12/15) after PTSMA, 18F-FDG images also showed decreased uptake at the septal regions in 5 HOCM patients (33.3%, 5/15) after PTSMA.Conclusion 99Tcm-MIBI images might be an important method to evaluate PTSMA results, and 18 F-FDG images showed important value as reference.
