Flattening of the interventricular septum (D-shaped left ventricle) in addition to high right ventricular tracer uptake and increased right ventricular volume found on gated SPECT studies strongly correlates with right ventricular overload.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFlattening of the interventricular septum (D-shaped left ventricle) detected during echocardiographic examination is correlated with significant right ventricular (RV) overload. There are no reports of this finding with cardiac gated single photon emission computed tomography (SPECT) imaging. We report an observational study correlating this finding with the presence of RV overload. METHODS AND
resultsRetrospectively, we compared 8 cases with flattening of the interventricular septum on cardiac gated SPECT imaging for which echocardiographic correlations and clinical data were available regarding the presence of RV overload. All patients but 1 had pulmonary hypertension ranging from 42 to 52 mm Hg measured by echocardiographic Doppler studies. All patients but 1 had reasons for RV overload (chronic obstructive pulmonary disease in 3, history of atrial septal defect in 3, pulmonary embolism in 1, and obstructive sleep apnea in 1). Septal flattening present on gated SPECT images was seen in 50% of the cases by echocardiography. Other signs of RV overload (RV enlargement, RV hypertrophy) were observed by echocardiography in 5 patients and by the gated SPECT in 7 patients.
conclusionThe presence of interventricular septal flattening on gated SPECT studies correlates with RV overload and should be routinely assessed during interpretation of gated SPECT studies.
