Abstract

This study evaluates mid-term outcomes of transcatheter plug closure (AVP2) for LVOT pseudoaneurysms post-aortic valve surgery. Three patients (EuroScore 1.92-9.65) showed complete closure at 4.5-year follow-up, supporting its efficacy as a minimally invasive alternative.

Introduction

LVOT pseudoaneurysms require urgent intervention. Transcatheter closure offers a safe option for high-risk patients.

Case Study

Case 1 (74F, redo AVR):

Imaging: LVOT pseudoaneurysm (neck 8.5mm).

Intervention: AVP2 10mm via trans-arterial approach.

Follow-up: Aneurysm resolved at 4.5 years.

Conclusions

1.AVP2 is effective for wide-neck pseudoaneurysms.

2.Transcatheter approach reduces perioperative risks.

3.Lifelong anticoagulation is recommended.
