Abstract
Transcatheter edge-to-edge mitral valve repair (TEER) is an established alternative for patients with severe, symptomatic mitral regurgitation (MR) at high surgical risk. The TEER procedure requires transseptal access, therefore might lead to the development of persistent iatrogenic atrial septal defect (iASD). The clinical significance of iASD and optimal management particularly from a long-term perspective is not clear. Herein, we described a case report of a 76-year-old female with prior left atrial appendage occlusion and severe MR that underwent a TEER procedure using MitraClip® (MC) system. After the MC implantation, she developed acute hypoxemia due to interatrial right-to-left shunt and required immediate iASD closure.
