A new device for paravalvular leak closure
نویسندگان
چکیده
Percutaneous closure of a prosthetic paravalvular leak (PVL) is a challenging procedure. Operators must use devices constructed for other applications. We present the use of a device which is specifically designed for PVL closure. To the best of our knowledge, there is no publication in MEDLINE reporting the use of the device.

Paravalvular leak closure with the Amplatzer Vascular Plug III device: immediate and short-term results.
INTRODUCTION AND OBJECTIVES Percutaneous paravalvular leak closure is a complex procedure with varying success rates; the lack of closure devices specifically designed for this purpose has hampered this technique. The characteristics of the Amplatzer Vascular Plug III appear to be well suited for paravalvular leak closures; however, the available data are limited to case reports or small series...

: We report here the mechanical interference between mitral bioprostheses and devices currently adopted for percutaneous paravalvular leak closure as a possible cause for late dislodgement and embolization of successfully implanted and apparently stable closure devices.The images included in this study demonstrate that the topographical relationship of the target leak with the bioprosthetic val...

Percutaneous closure of paravalvular leaks has emerged as an alternative to repeated surgeries. Different percutaneous techniques and various devices have been used, off-label, for paravalvular leak closure. For mitral leaks, antegrade transseptal, retrograde transfemoral, and retrograde transapical techniques have been developed. In the antegrade transseptal approach, an arteriovenous guidewir...

Paravalvular leaks (PVLs) are a well-recognized complication of prosthetic valve replacement. Perivalvular prosthetic regurgitation causes significant morbidity and is associated with high perioperative mortality if open surgical repair is required. PVLs manifest with symptoms of congestive heart failure, hemolysis, or in most cases, the combination of both. In recent years, the development of ...
متن کاملA Quick Guide to Paravalvular Leak Closure.
Paravalvular leak (PVL) is a seldomly covered aspect of structural heart disease. However, this is a condition that frequently presents after valvular replacement. This article will cover the diagnosising and treating PVL (i.e. imaging, access, and device selection). In addition, specific aspects of aortic and mitral PVL closure will be covered in this review.
