Successful WATCHMAN Device Implantation in a Patient with IVC Filter Thrombosis and Iliac Vein Occlusions

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Device Technology

Background:

• Percutaneous left atrial appendage occlusion is a proven stroke prevention strategy for nonvalvular atrial fibrillation (NVAF).
• Patients with NVAF often have comorbidities increasing stroke and bleeding risks.
• Venous system abnormalities, such as occlusions or filter thrombosis, can complicate percutaneous procedures.

Purpose of the Study:

• To report a successful WATCHMAN device implantation for left atrial appendage occlusion.
• To demonstrate the feasibility of this procedure in a patient with complex venous occlusions.

Main Methods:

• A WATCHMAN device was successfully implanted percutaneously.
• The procedure was performed in a patient with a history of inferior vena cava filter thrombosis and bilateral iliac vein occlusions.

Main Results:

• Successful deployment and sealing of the WATCHMAN device.
• The procedure was technically successful despite challenging venous anatomy.

Conclusions:

• Left atrial appendage occlusion with the WATCHMAN device can be safely performed even in patients with significant venous system occlusions.
• This case expands the understanding of WATCHMAN device applicability in complex patient scenarios.
