Is transcatheter closure using occluder devices a suitable alternative to redo-surgery for patients with paravalvular leaks?
Is transcatheter closure using occluder devices a suitable alternative to redo-surgery for patients with paravalvular leaks?
Transcatheter closure of paravalvular leaks is a viable, less invasive alternative to high-risk redo-surgery for selected patients, facilitated by specifically designed devices and 3D real-time echocardiography.
