Is this trial a fit for you?

Likely a good fit

Adults with acute symptomatic pulmonary embolism (<14 days) and right ventricle to left ventricle end-diastolic diameter ratio ≥1, for whom the investigator plans to use the EkoSonic Endovascular System with rt-PA.

Probably not a fit

Patients without these criteria or in whom the device is not used as planned may not see a benefit.

What this trial studies

This is a prospective, multi-center, single-arm observational study enrolling up to 60 patients in total to collect real-world outcomes of the EkoSonic Endovascular System used with rt-PA for acute PE. The trial observes safety and efficacy during standard clinical practice without randomization. Eligibility includes adults with acute symptomatic PE (less than 14 days) and specific echocardiographic criteria indicating right ventricular strain. Data will be collected from real-world use at The First Affiliated Hospital, Sun Yat-sen University in Guangzhou, sponsored by Boston Scientific. The study design emphasizes naturalistic outcomes rather than a controlled comparison.

Why it matters

Potential benefit: If successful, the approach could support safer, effective use of the EkoSonic System in selected Chinese patients with acute PE.

How similar studies have gone: Previous real-world and device-based PE studies have shown promise, but this specific Chinese real-world, single-arm observational approach is largely exploratory.
