Percutaneous device closure for Paravalvular leak- A single centre experience.

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Paravalvular leak (PVL) is a complication after surgical valve replacement, occurring in 5-17% of cases.
• Significant PVLs can lead to heart failure, hemolysis, and other adverse events.
• Current management options for PVLs can be limited or invasive.

Purpose of the Study:

• To evaluate the safety and efficacy of percutaneous device closure for significant paravalvular leaks.
• To assess the technical and procedural success rates of transcatheter PVL closure.
• To determine the feasibility of this minimally invasive approach for PVL management.

Main Methods:

• A retrospective analysis of patients undergoing transcatheter device closure for PVLs.
• Closure procedures were performed for leaks in mitral, aortic, and combined positions.
• Data collected included technical success, procedural success, and patient outcomes.

Main Results:

• Transcatheter device closure was performed in 45 PVLs across 42 patients.
• Successful closure was achieved in the mitral position (23 cases), aortic position (20 cases), and combined positions (2 cases).
• High rates of technical success (93.33%) and procedural success (91.11%) were observed.

Conclusions:

• Percutaneous device closure is a safe and effective treatment for symptomatic paravalvular leaks.
• Transcatheter PVL closure provides a viable alternative to surgical re-intervention.
• This minimally invasive technique demonstrates favorable success rates in managing significant PVLs.
