Effect of Percutaneous Suction Thromboembolectomy on Improved Right Ventricular Function

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Surgery

Background:

• Venous thromboembolism (VTE) is a major cause of cardiovascular mortality.
• Traditional surgical interventions for VTE carry high morbidity.
• Pharmacologic therapy may be insufficient for patients with severe hemodynamic compromise.

Observation:

• This study evaluated the initial experience with the AngioVac system for percutaneous suction thromboembolectomy.
• Thirteen patients with VTE underwent the procedure between March 2013 and August 2015.
• Indications included failed catheter-directed therapy, thrombolysis contraindications, bleeding complications, and clot-in-transit.

Findings:

• The overall survival to hospital discharge was 77% (10 out of 13 patients).
• Significant improvement in right ventricular function was observed post-procedure (P=0.031).
• Pre-procedure, 62% of patients had severe RV dysfunction; post-procedure, only 17% had severe dysfunction.

Implications:

• Percutaneous suction thromboembolectomy is a promising, minimally invasive therapeutic option for VTE.
• The AngioVac system demonstrates safety and efficacy in reducing clot burden.
• This technique can lead to improved cardiac function in VTE patients.
