Retrograde Transseptal Pulmonary Vein Transcatheter Plug Closure for Pulmonary Arteriovenous Malformation

Abstract

Pulmonary arteriovenous malformations (PAVMs) may manifest with bleeding or embolic events necessitating intervention. Transcatheter coil embolization through the pulmonary artery (PA) is an established approach. We present a case of recurrent PAVMs despite numerous PA coil embolizations. PAVM occlusion was achieved through plug placement by a transseptal and pulmonary venous approach. (Level of Difficulty: Advanced.).
