Iatrogenic ASD gradient as a marker of residual mitral regurgitation severity after M-TEER procedure
Assessment of procedural success following transcatheter mitral edge-to-edge repair (M-TEER), including non-invasive parameters, remains challenging. The association between iatrogenic atrial septal defect (iASD) gradient and post-procedural three-dimensional vena contracta area (3D-VCA) as a marker of res...
