Key result
TEER reverses unilateral pulmonary edema caused by eccentric MR targeting the right superior pulmonary vein.
Why the study?
Unilateral pulmonary edema is uncommon and frequently misattributed to pneumonia, delaying appropriate heart failure care.
Does transcatheter edge-to-edge repair (TEER) reverse unilateral pulmonary edema caused by severe eccentric mitral regurgitation?
Does transcatheter edge-to-edge repair (TEER) reverse unilateral pulmonary edema caused by severe eccentric mitral regurgitation?
Multimodality imaging confirms that unilateral pulmonary edema can be caused by eccentric MR directed at a specific pulmonary vein, which is reversible with transcatheter edge-to-edge repair.

Supports TEER for unilateral pulmonary edema due to eccentric MR; confirms jet-direction mechanism via multimodality imaging.
Yoshida et al. (2026) studied this question. Transcatheter edge-to-edge repair reversed unilateral pulmonary edema caused by eccentric mitral regurgitation targeting the right superior pulmonary vein as shown by multimodality imaging.
