Prevalence and predictors of aortic root abscess among patients with left-sided infective endocarditis: a cross-sectional comparative study

The Egyptian Heart Journal, 2020
Background Aortic root abscess (ARA) is a major complication of infective endocarditis that is associated with increased morbidity and mortality. Limited data are present about patient characteristics and outcomes in this lethal disease.

Regurgitant leak from the area between the stent post and the sewing ring of a stented bovine pericardial valve implanted in the aortic valve position

Cardiovascular Ultrasound, 2010
Biologic valves can sometimes have a small closure or leakage backflow jet originating from the central coaptation point. This is physiologic regurgitation that usually only requires monitoring, and not treatment.

Exploring hemolysis due to paravalvular leakage in artificial heart valves [PDF]

, 2020
Artificial heart valves require a surgical suture to keep them in place. These sutures can become infected or degrade over time, which can give rise to the phenomenon of paravalvular leakage.

Interventional closure of paravalvular leakage after transcatheter aortic valve implantation [PDF]

European Heart Journal, 2012
An 83-year-old female patient presented with pulmonary oedema 2 months after transcatheter aortic valve implantation (TAVI) with a balloon-expandable transcatheter heart valve (THV) (Edwards SAPIEN XT 23 mm). The THV had been properly sized [maximum annulus diameter 21 mm in three-dimensional transoesophageal echocardiography (3D-TEE) and 24 × 20 mm in

Minimally invasive surgery versus transcatheter aortic valve replacement: a systematic review and meta-analysis

Open Heart, 2021
Transcatheter aortic valve replacement (TAVR) has recently been approved for use in patients who are at intermediate and low surgical risk. Moreover, recent years have witnessed a renewed interest in minimally invasive aortic valve replacement (miAVR ...

Hemolysis after percutaneous paravalvular leak repair

, 2016
Paravalvular leak is a common complication after surgical mitral valve replacement. Surgically implanted prosthetic valves are complicated with paravalvular leaks in 17%.(1) Surgical closure of paravalvular leaks is the most common therapy for these ...
