Clinical research status and progress of redo-transcatheter aortic valve replacement for structural biovalvular degeneration
Biological valves can lead to structural valve degeneration(SVD)over time and due to various factors,reducing their durability.SVD patients need to undergo valve replacement surgery again,while traditional open chest surgery can cause significant trauma and patients often give up treatment due to intolerance.Research has shown that as an alternative treatment option for reoperation of thoracic valve replacement surgery,redo-transcatheter aortic valve replacement for SVD is safe and effective,but still faces many challenges,including prosthesis-patient mismatch,high cross valve pressure difference,and coronary obstruction.This article aims to review the strategies,clinical research status and progress of redo-transcatheter aortic valve replacement in SVD patients.
