Mitral Paravalvular Leak: Clinical Implications, Diagnosis and Management
Journal of Clinical Medicine, 2022 Paravalvular leak incidence after mitral surgical replacement ranges from 7% to 17%. Between 1% and 5% of these are clinically significant. Large PVLs can cause important clinical manifestations such as heart failure or haemolysis.

Percutaneous management of paravalvular leaks
Heart, 2021Paravalvular leak (PVL) is a challenging complication of valve replacement surgery that can cause heart failure and haemolysis. Surgical repair is the traditional treatment for severe, symptomatic PVL, but many patients with PVL fall into high-risk categories for redo surgery.

Percutaneous Paravalvular Leak Closure
Cardiology Clinics, 2013Percutaneous paravalvular leak closure is increasingly being performed as an alternative to reoperation in patients with symptomatic prosthetic paravalvular regurgitation. This article reviews the pathogenesis of paravalvular leaks and percutaneous techniques for closure.

Percutaneous Paravalvular Leak Repair
Interventional Cardiology Clinics, 2022Paravalvular leaks (PVLs) are challenging lesions that require a comprehensive understanding of surgical and transcatheter heart therapies, multimodality imaging, and transcatheter techniques. Approach to a transcatheter heart valve (THV) or surgical prosthesis for PVL differs in terms of options and varies according to the location (aortic or mitral).

Update in Paravalvular Leak Closure
Current Cardiology Reports, 2021Given the low occurrence of clinically important paravalvular leak (PVL), there are no large registries or trials in this space to investigate management strategies. This review integrates newer evidence, particularly in imaging guidance for these complex procedures, novel techniques and approaches that our group has taken, as well as approaches to ...

Surgical treatment of paravalvular abscess: long-term results.
European Journal of Cardio-thoracic Surgery, 2007 Objective: To examine the outcomes of surgery for active infective endocarditis with paravalvular abscess. Methods: Paravalvular abscess was defined as infective necrosis of the valve annulus that required patch reconstruction before implanting a new ...

Percutaneous management of paravalvular leaks
Nature Reviews Cardiology, 2019Paravalvular leak (PVL) is a complication that occurs in 5-17% of patients after surgical prosthetic valve implantation. Whereas PVLs can be benign, some PVLs are associated with substantial morbidity and mortality. Percutaneous closure using occluders specifically designed to improve closure and reduce procedural complications has now become the first-

Predictors of Mortality in Paravalvular Abscess
Journal of the American Society of Echocardiography, 2005Paravalvular abscess formation is an ominous complication of infective endocarditis; however, prognostic variables in paravalvular abscess are poorly defined.We examined our experience in patients with paravalvular abscess between 1987 and 2004. Clinical, echocardiographic, microbiologic, and surgical data were examined.There were 45 patients (17 ...

Mitral Paravalvular Leak Closure
Interventional Cardiology Clinics, 2016For patients with paravalvular mitral prosthetic regurgitation, percutaneous repair is an established therapy for the treatment of symptoms of heart failure or hemolytic anemia. Percutaneous repair of paravalvular mitral regurgitation is a complex procedure with unique technical challenges, even when performed in experienced centers. Herein, the author

Interventional management of paravalvular leak
Heart, 2018### Learning objectives Paravalvular leak (PVL) is a common and underdiagnosed condition affecting both surgical and transcatheter prosthetic heart valves.1–3 Characterised by a gap between the prosthetic valve and the native annular tissue, PVL results in regurgitation of blood from downstream to upstream chamber, occurring most often in conditions ...
