BACKGROUND paravalvular leak(PVL),also known as paravalvular prosthetic regurgitation,is not a rare complication after surgical valve replacement,and it may cause varying degrees of heart *** transcatheter closure of PVL is technically demanding and *** SUMMARY A 68-year-old man presented with degenerative mitral regurgitation with heart failure,New York Heart Association functional class *** received bioprosthetic mitral valve replacement in December *** was noted at the location of the aorto-mitral curtain in transesophageal echocardiography without signs of endocarditis or dehiscence of the bioprosthetic *** transcatheter closure of the mitral PVL was performed efficiently using the EchoNavigator virtual marker and Agilis NxT steerable *** This case highlights that the EchoNavigator virtual marker and Agilis NxT steerable introducer can facilitate transseptal transcatheter closure of mitral PVL by reducing the procedure time and contrast media.

Trans-Frame Aortic Regurgitation of New-Generation Aortic Bioprosthesis

引用

World Journal of Cardiovascular Surgery 2024年第4期14卷 41-44页

作者： Michael Timothy Simpson Kasmir Ramo Vinayak Bapat Andrea Miltiades Isaac George Division of Cardiothoracic Surgery New York-Presbyterian Hospital Columbia University Medical Center New York USA Division of Cardiothoracic Anesthesia New York-Presbyterian Hospital Columbia University Irving Medical Center New York USA Division of Cardiothoracic Surgery Abbott Northwestern Hospital Minneapolis Heart Institute Minneapolis USA

A widely used aortic valve bioprosthesis is susceptible to regurgitation between the sewing ring and the frame of the valve due to its relatively thin fabric coverage. In some cases this leak has been shown to resolve with administration of protamine, however, tension on this area from annular sutures placed in an asymmetric bicuspid valve annulus may exacerbate the defect.
