Thallium-201 myocardial scintigraphy was performed on 55 patients with various types of right ventricular overloading. The right ventricular (RV) free wall was visualized in 39 out of the 55 patients (71%). The mean values of right ventricular systolic pressure (RVSP) and pulmonary artery mean pressure (PAMP) in the visualized cases (uptakers) were 54.6±24.1 and 30.5±15.3 mmHg, respectively. These values were significantly higher than those of the non-visualized cases (non-uptakers). There were 12 RVSP-"normotensive" uptakers and 15 PAMP-"normotensive" uptakers. The RV free wall images were classified into three types according to their morphological features. Type I was predominantly seen in cases of RV pressure overloading, type II in RV volume overloading and type III in combined ventricular overloading. RVSP in the type III group was significantly higher than that in other two groups. The radioactivity ratio in RV free wall and interventricular septum (IVS), the RV/IVS uptake ratio was calculated using left anterior oblique (LAO) view images. The RV/IVS uptake ratio closely correlated with RVSP and PAMP (r = 0.88 and 0.82, respectively). In each group of RV free wall image, there were also close correlations between the RV/IVS uptake ratio and both RVSP and PAMP. Our results indicate that the RV/IVS uptake ratio can be used as a parameter for the semi-quantitative estimation of right ventricular overloading.
