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.
