A Novel Multiparametric Model Integrating Aortoseptal Angle to Predict the Origin of Outflow Tract Ventricular Arrhythmias.

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
Background: Localizing the site of origin of outflow tract ventricular arrhythmias (OTVA) before ablation remains challenging despite existing ECG algorithms. Anatomical alterations of the aortic root associated with left ventricular outflow tract (LVOT) origin can be visualized through aortoseptal angle measurement. This study investigated the aortoseptal angle for predicting LVOT origin and improving the predictive power of current ECG algorithms. Methods: Patients undergoing successful OTVA ablation at a national cardiovascular referral hospital were enrolled. Transthoracic echocardiography measured the aortoseptal angle before ablation. Patients with structural abnormalities, multifocal arrhythmias, reduced ejection fraction, unsuccessful ablation, or non-inducible VAs were excluded. Multivariable logistic regression was used to develop a diagnostic model. Results: Forty-eight patients were included (44.9 ± 12.2 years, 79.8% female). Patients with LVOT origin (17.1%) had higher hypertension prevalence (71.4% vs. 17.6%; Conclusions: Aortoseptal angle measurement by echocardiography effectively identifies LVOT origin. Integration with hypertension status and V2 transition ratio substantially enhances diagnostic accuracy, supporting the use in pre-ablation assessment.
