Paravalvular leak transcutaneous closure, diagnosis, and procedure essential
Paravalvular Leaks (PVLs) are a complication of a surgical or percutaneous valve replacement.
They are persistent defects between the native annulus and the sewing ring, which result in a
regurgitant prosthesis. They are detected in 2%-18% of patients after a surgical valve replacement.
Clinical manifestations of PVLs are seen in 1% to 5% of defects and have a severe prognosis.
Surgery redux was the only available treatment to improve these patients? outcomes. But it is
usually a high-risk surgery in frail patients with a long history of valve disease. Percutaneous
PVL closure emerged as a safer and vital therapeutic option with promising results. Nevertheless,
this technique needs a careful pre-procedural assessment and demands high technical expertise.
It still has several limitations.
This article focuses on PVLs after a surgical valve replacement and essential steps toward
assessment, indication, and achievement of a transcatheter PVL closure (TPVL). Author(s): Mghaieth Zghal Fathia, Farhati Abdeljelil, Boudiche Slim, Manel Ben Hlima, Rekik Bassem
