Transapical closure of mitral paravalvular leaks with use of amplatzer vascular plug III

J Invasive Cardiol. 2013 Oct;25(10):497-501.

Abstract

Introduction: Paravalvular leak (PVL) may complicate cardiac valve replacement surgery. Radical treatment is required if a PVL produces heart failure (HF) symptoms or severe hemolysis. Even though transcatheter PVL closure (TPVLC) has become a valid alternative to reoperation, a number of anatomical conditions may prove technically challenging for transvascular access. We intended to verify the utility of transapical access in such settings.

Methods: We report a prospective series of 7 patients with mitral PVLs who underwent transapical TPVLC. The Heart Team made the choice of treatment and Amplatzer Vascular Plug III devices were used off-label as occluders.

Results: Transapical TPVLC enabled excellent sealing of mitral PVL in 6 cases. This resulted in HF symptom reduction and decreased NT-proBNP plasma concentration. No procedure-related complications occurred.

Conclusions: Transapical access seems to be an efficient and safe alternative for transvascular approach for mitral TPVLC, but further technical development is still needed.
