Why the study?
Iatrogenic atrial septal defects after transseptal puncture can cause hemodynamic decompensation and worsening outcomes, highlighting the need to evaluate their assessment and indications for closure.
Iatrogenic atrial septal defects following transseptal puncture for structural heart interventions may require immediate or delayed closure to prevent hemodynamic decompensation.
Clinicians should monitor for hemodynamic effects of iatrogenic ASDs after TEER; case reports leave open incidence and predictors.
The evolution of percutaneous procedures that use transseptal puncture to treat left-sided structural heart disease has led to the emergence of iatrogenic atrial septal defects as a potential complication. These defects can result in hemodynamic decompensation and worsening clinical outcomes. Some iatrogenic atrial septal defects require immediate closure, others do not. This case report presents 2 patients who underwent transcatheter edge-to-edge mitral valve repair with transseptal puncture and required iatrogenic atrial septal defect closure (1 immediate and 1 delayed). The goal of this report is to highlight iatrogenic atrial septal defect assessment and the possible need for closure after transseptal puncture.
