Mechanical Thrombectomy Reduces Increased High Sensitivity Troponin Levels in Intermediate-High Risk Pulmonary...

Area of Science:

• Cardiology
• Pulmonary Medicine
• Interventional Radiology

Background:

• Pulmonary embolism (PE) is a leading cause of mortality, often misdiagnosed, worsening patient prognosis.
• Disease severity and prognosis in PE are heavily influenced by risk factors, dictating treatment strategies.
• Mechanical thrombectomy is an emerging intervention for PE, but its short-term effects require further elucidation.

Purpose of the Study:

• To analyze the short-term clinical, laboratory, and hemodynamic effects of mechanical thrombectomy in patients with symptomatic pulmonary artery embolism.
• To evaluate the impact of the FlowTriever device on key physiological parameters in intermediate-high and high-risk PE patients.

Main Methods:

• Retrospective analysis of 32 patients with symptomatic pulmonary embolism undergoing mechanical thrombectomy with the FlowTriever device.
• Inclusion criteria: PE confirmed by CT pulmonary angiography, classified as intermediate-high or high risk per ESC guidelines.
• Outcome measures: changes in troponin, lactate, pulmonary artery pressures, and vital signs.

Main Results:

• Immediate reductions in heart rate, pulmonary artery pressure, and right-to-left ventricle ratio post-procedure.
• Improved arterial oxygen saturation and reduced demand observed.
• Significant decrease in elevated high-sensitivity troponin and lactate levels.

Conclusions:

• Mechanical thrombectomy in intermediate-high risk pulmonary artery embolism patients leads to rapid and significant reductions in myocardial and systemic biomarkers.
• These biomarker reductions have demonstrated prognostic relevance.
• The findings support mechanical thrombectomy as an effective treatment for improving hemodynamic stability and reducing disease markers in PE.
