Detailed Description:

Despite advances in prophylaxis, diagnostic modalities, and therapeutic options, pulmonary embolism remains a commonly under diagnosed and lethal entity. In the United States approximately 150,000 patients per year are diagnosed with acute pulmonary embolisms. Many additional deaths occur each year in the United States as a result of undiagnosed massive pulmonary embolisms. Taking these patients into account, it is thought that up to 600,000 patients develop a pulmonary embolism annually in this country. In patients with acute pulmonary embolism, the most common cause of early death is right ventricular failure.

In addition to anticoagulation therapy, several reperfusion therapies are being used to reverse right ventricular failure: systemic thrombolysis, surgical embolectomy, and catheter based therapy. Given the drawbacks of systemic thrombolytic therapy or surgical embolectomy, percutaneous catheter treatment is a reasonable alternative for patients with contraindications to systemic thrombolytic therapy or surgery. Current international consensus guidelines support the use of catheter interventions for selected pulmonary embolism patients at increased risk of adverse clinical outcomes.

The AngioJet Ultra PE Thrombectomy catheter introduces a pressurized high velocity saline stream through a catheter tip so that the clot within a blood vessel is trapped, broken into small pieces and aspirated from the body.

  3. Availability of a baseline transthoracic echocardiogram with sufficient image quality permitting the measurement of right ventricular (RV) and left ventricular (LV) dimensions in the apical or subcostal four-chamber view
  4. Echocardiographic evidence of right ventricular dilatation with a subannular RV/LV ratio ≥ 0.9 from the apical or subcostal four-chamber view
