Key result
High-risk acute pulmonary embolism patients had a significantly higher median CT pulmonary embolism index (24.69%) compared to non-high-risk patients (8.58%, P<.05) on ECG-gated CTA.
Why the study?
Can ECG-gated pulmonary artery CTA effectively evaluate right ventricular function and disease severity in patients with acute pulmonary embolism?

Can ECG-gated pulmonary artery CTA effectively evaluate right ventricular function and disease severity in patients with acute pulmonary embolism?
ECG-gated pulmonary artery CTA is a suitable non-invasive imaging modality for assessing the severity of acute pulmonary embolism and evaluating right ventricular function.

May support gated CTPA for RV assessment in APE; leaves open whether it improves risk stratification.
OBJECTIVE: To evaluate right ventricular function in patients with acute pulmonary embolism (APE) using electrocardiogram-gated CTA and to discuss the clinical value of pulmonary artery CTA PATIENTS AND METHODS: Based on death risk evaluation, 86 APE patients were divided into high-risk group (n=46) and non-high-risk group (n=40). The CT pulmonary embolism (PE) index and parameters of right ventricular function were analyzed from the CTPA images and compared between the two groups. Potential correlation between the two was also discussed. RESULT: CT PE index (median 24.69%) of the high-risk group was obviously higher than that of the non-high-risk group (median 8.58%) (P<.05). Except the diameter of superior vena cava, all other parameters of right ventricular function were significantly different between the two groups (P<.05). CT PE index was correlated with the parameters of right ventricular function. CONCLUSION: ECG-gated pulmonary artery CTA is suitable for assessing the severity of APE and right ventricular function.

Liang et al. (2016) conducted an observational in Acute pulmonary embolism (n=86). High-risk acute pulmonary embolism vs. Non-high-risk acute pulmonary embolism was evaluated on CT pulmonary embolism (PE) index (p=<.05). High-risk acute pulmonary embolism patients had a significantly higher median CT pulmonary embolism index (24.69%) compared to non-high-risk patients (8.58%, P<.05) on ECG-gated CTA.
