Critical Appraisal

Title: Randomized Controlled Trial of Mechanical Thrombectomy With Anticoagulation Versus Anticoagulation Alone for Acute Intermediate-High Risk Pulmonary Embolism: Primary Outcomes From the STORM-PE Trial.
Background: Patients with intermediate-high risk pulmonary embolism are at risk of early clinical decompensation and mortality due to elevated RV/LV diameter ratio. Reperfusion therapy aims to relieve acute RV pressure overload.
Study Question: Does mechanical thrombectomy with anticoagulation improve outcomes compared to anticoagulation alone in intermediate-high risk PE?
Study Design: Randomized controlled trial with 1:1 randomization.
Population: 100 adults with acute intermediate-high risk PE, normotensive, RV/LV ratio ≥1.0, and elevated cardiac biomarkers.
Intervention: Mechanical thrombectomy with anticoagulation.
Comparison: Anticoagulation alone.
Primary Outcome: Change in RV/LV ratio at 48 hours.
Secondary Outcomes: Major adverse events within 7 days, change in vital signs, and PA obstruction at 48 hours.
Key Statistics: Mean reduction in RV/LV ratio was 0.52±0.37 for CAVT vs 0.24±0.40 for AC; difference of 0.27 (95% CI, 0.12, 0.43; P<0.001).
Results: CAVT significantly reduced RV/LV ratio more than AC alone, with no significant difference in MAE rates between groups.
Risk of Bias – RoB 2:
Randomization Process

Randomization was appropriately conducted with allocation concealment.

Deviations from Intended Interventions

Interventions were delivered as intended with no significant deviations.

Missing Outcome Data

Outcome data were complete with minimal loss to follow-up.

Measurement of the Outcome

Outcomes were measured using standardized and validated methods.

Selection of the Reported Result

All prespecified outcomes were reported, reducing the risk of selective reporting.

Take Home: Mechanical thrombectomy with anticoagulation is more effective than anticoagulation alone in reducing RV/LV ratio in intermediate-high risk PE, without increasing adverse events.

JournalFeed Summary

Spoon Feed
Mechanical thrombectomy with anticoagulation significantly reduces RV/LV ratio in intermediate-high risk PE compared to anticoagulation alone, without increasing major adverse events.

Thrombectomy triumphs in taming PE's RV/LV ratio.
The STORM-PE trial is a landmark RCT evaluating mechanical thrombectomy (MT) combined with anticoagulation (AC) versus AC alone in patients with intermediate-high risk pulmonary embolism (PE). This study enrolled 100 patients who were randomized to receive either MT with AC or AC alone. The primary outcome was the change in the right-to-left ventricular (RV/LV) diameter ratio at 48 hours. Results showed that MT significantly reduced the RV/LV ratio more than AC alone (mean difference of 0.27, 95% CI 0.12 to 0.43, P<0.001). Secondary outcomes, including major adverse events (MAE) within 7 days, were similar between groups, with no significant difference in MAE rates (CAVT 4.3% vs AC 7.5%, P=0.681). The study concludes that MT is effective in rapidly improving RV function and hemodynamics in PE without increasing adverse events.

How might this change our practice?
Consider mechanical thrombectomy for intermediate-high risk PE to improve RV function and hemodynamics.
