There is considerable interest in percutaneous closure of perivalvular leaks without the need
for repeat surgery. Successful percutaneous closure of these defects requires extensive …

This study was conducted to assess the usefulness of transesophageal echocardiography
(TEE) as a guide in the percutaneous transcatheter occlusion of paravalvular defects and in …

BACKGROUND: The percutaneous closure of mitral paravalvular leaks has been reported in
patients who are poor operative candidates. Unsuccessful percutaneous closure of leaks …

Percutaneous mitral valve closure is a novel technique in evolution as an alternative therapy
for nonsurgical candidates with significant mitral regurgitation. Current use has been limited …

Paravalvular regurgitation affects 5% to 17% of all surgically implanted prosthetic heart
valves. Patients who have paravalvular regurgitation can be asymptomatic or present with …

A 47‐year‐old female with symptomatic mitral stenosis from a prior undersized mitral
annuloplasty ring underwent mitral valve replacement with a mechanical valve. Later, she …

For patients with paravalvular mitral prosthetic regurgitation, percutaneous repair is an
established therapy for the treatment of symptoms of heart failure or hemolytic anemia …

Approximately 5–10% of patients who undergo prosthetic mitral valve replacement develop
some degree of para-(peri-) valvular regurgitation (leaks) resulting in congestive heart …

Transcatheter closure of mitral prosthetic paravalvular leak (PVL) has been hampered by
technical challenges and the lack of closure devices specifically designed for this purpose …

Transcatheter closure of mitral paravalvular leaks has become an accepted alternative to
surgical repair, especially in patients at high risk for reoperation. Device placement using …
