  • Title: Iatrogenic Atrial Septal Defect After Percutaneous Mitral Valve Repair With MitraClip: Should We Consider Closing Them Routinely?

    Abstract:
    Percutaneous MitraClip intervention for treatment of severe mitral regurgitation in high surgical risk patients requires large-diameter transseptal sheaths that can result in iatrogenic atrial septal defect (iASD), and its prevalence is higher compared with non-MitraClip procedures. This iASD is not routinely closed because the possible consequences are still not fully understood. However, we believe it is important to identify patients who may benefit from its closure immediately after the procedure to prevent hemodynamic deterioration and long-term negative clinical outcomes. We describe our experience with 2 patients who required iASD closure after MitraClip procedure due to right-to-left shunt resulting from increase in right heart pressures.
