Pathogenesis of paravalvular leakage as a complication occurring in the late phase after surgery

Journal of Artificial Organs, 2011
Paravalvular leakage (PVL) remains an unavoidable late complication after valve surgery. We indicate surgery only cases with progressive congestive heart failure and/or hemolytic anemia. We review our clinical experiences of PVL surgery. Between 1992 and 2009 we experienced 8 cases of aortic PVL-6 subjects after primary aortic valve replacement (AVR ...

Transapical mitral valved stent implantation: Enhanced survival and decreased paravalvular leakages

International Journal of Cardiology, 2014
This study presents the recent results of transapical implantation of a new design of a mitral valved stent with up to three months follow-up.A self-expanding re-designed mitral valved stent was implanted via transapical approach into the beating heart of eight pigs. Echocardiographic- and hemodynamic parameters were assessed before (n=8), at 1h (n=8),

Paravalvular Leakage After Transcatheter Aortic Valve Implantation

2017
Transcatheter aortic valve implantation (TAVI) is the treatment of choice for inoperable or high-risk patients with severe aortic stenosis and is now expanding to intermediate- and low-risk patients [1–3]. A frequently seen complication after TAVI is paravalvular leakage (PVL), which is considered the Achilles’ heel of TAVI since several studies have ...

Balloon-Assisted Paravalvular Leakage Crossing for Transcatheter Closure: A Pilot Study

Journal of Invasive Cardiology
Transcatheter closure of paravalvular leaks (PVL) is an established treatment method. However, because of the frequent anatomical complexity of the PVL channel and lack of dedicated equipment, PVL crossing remains challenging. This study aims to provide an initial assessment of the safety and efficacy of using an angioplasty balloon to facilitate PVL ...

Low Incidence of Paravalvular Leakage With the Balloon-Expandable Sapien 3 Transcatheter Heart Valve

The Annals of Thoracic Surgery, 2015
We evaluated the clinical and hemodynamic performance of the new balloon-expandable Sapien 3 (Edwards Lifesciences, Irvine, CA) transcatheter heart valve (S3 THV).Between April 2013 and January 2015, 54 consecutive high-risk patients presenting with aortic stenosis were treated with the new S3 THV.

Complicated Aortic Paravalvular Leakage with Aneurysmal Tunnel Formation in a Young Man

2021
The patient is 23 year-old-male whom had history of coarctation of aorta angioplasty and subaortic web resection at childhood. In follow-up echocardiography he had severe aortic stenosis and bicuspid aortic valve, so surgical AVR performed uneventfully.

Quantitative Doppler for Estimation of Paravalvular Leakage after Transcatheter Aortic Valve Implantation.

The Journal of heart valve disease, 2016
The echocardiographic grading of paravalvular aortic leakage (PVL) after transcatheter aortic valve implantation (TAVI) severity is challenging. The study aim was to assess the value of quantitative Doppler echocardiography to monitor PVL severity.A total of 100 subjects was enrolled in the study, including 65 consecutive patients who had undergone ...

[Evaluation of paravalvular leakage occurring after the 3rd mitral valve replacement].

Kyobu geka. The Japanese journal of thoracic surgery, 2008
We evaluated the frequency of paravalvular leakage (PVL) in 21 patients who had undergone mitral valve replacement (MVR) 3 times or more in our department between January 1981 and December 2003. Of these 21 patients, 5 underwent MVR 4 times, including the one who underwent the 5th MVR.
