Summary
Endovascular extraction offers a potential alternative for right atrial thrombi when surgery or thrombolysis is contraindicated. This minimally invasive approach shows feasibility, though patient outcomes require further investigation.
Area of Science:
- Cardiology
- Interventional Radiology
Background:
- Traditional treatments for right atrial thrombi, such as surgical embolectomy and thrombolysis, carry high mortality risks.
- Many patients with right atrial thrombi have contraindications for these established therapies, necessitating alternative solutions.
Observation:
- This study evaluated the feasibility of endovascular right atrial embolectomy in two patients unsuitable for conventional treatments.
- A femoral approach was used, employing a basket device under fluoroscopic and transesophageal echocardiography (TEE) guidance to retrieve the thrombus.
Findings:
- The endovascular technique successfully trapped and removed thrombi from the right atrium.
- One patient experienced an immediate procedural death, highlighting potential risks associated with the intervention.
Implications:
- Endovascular extraction of right atrial thrombi presents a viable alternative, especially for high-risk patients.
- Further research is warranted to refine the technique and improve outcomes for this challenging condition.
