Color Doppler TEE Demonstrating Iatrogenic ASD Closure

Video Supplement to “Provisional Closure of an Iatrogenic Atrial Septal Defect for Shunt Reversal After Transcatheter Treatment of Tricuspid Regurgitation" [October 2019 Clinical Images article by Sugiura, et al].

We present a patient with severe tricuspid regurgitation who underwent transcatheter tricuspid valve repair (TTVR) using the MitraClip system, with the development of left-to-right shunt through an iatrogenic ASD. Diagnosis was made with the following video series of color Doppler TEEs. This case demonstrates that provisional occlusion of ASD after TTVR should be considered in patients with residual LR shunt and iatrogenic ASD.
