[Percutaneous closure of mitral perivalvular leak].

Paravalvular leak (PVL) is a complication observed in patients after prosthetic valve replacement. The incidence of PVL is estimated as 2-3%. The cause of PVL may be paravalvular infection, suture continuity disruption, damage of tissues around the annulus or limitation of disc mobility by thrombus or vegetation. The preferable method of treatment of PVL is surgery. Recently, percutaneous closure of PVL became an alternative method. We present a case of successfully completed percutaneous closure of PVL with the use of Amplatzer occluder device in a patient with mitral PVL.
