Paravalvular leak closure with two large size devices.

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Paravalvular leaks (PVL) are a known complication following valve replacement surgery.
• Significant PVLs can lead to severe complications such as heart failure and hemolysis, necessitating intervention.
• Surgical repair of PVLs carries high risks, making alternative treatments desirable.

Observation:

• The patient presented with a very large mitral paravalvular leak.
• The patient was deemed high-risk for conventional surgical re-intervention.
• Existing devices are not specifically designed for large PVL closure, posing a challenge.

Findings:

• A novel approach utilizing two large closure devices was employed for the mitral PVL.
• The combined device strategy successfully achieved closure of the very large PVL.
• This interventional technique offered a viable alternative to high-risk surgery.

Implications:

• This case suggests that dual large device closure can be effective for very large mitral PVLs in high-risk patients.
• It expands the interventional options for managing complex paravalvular leaks.
• Further research into device-specific adaptations for large PVL closure is warranted.
