Hyperacute Iatrogenic Atrial Septal Defect Expansion Driven by Tricuspid Regurgitation Jet Impingement

Key Result

Tricuspid regurgitation jet impingement and impaired atrial compliance can cause rapid, life-threatening enlargement of iatrogenic atrial septal defects after M-TEER.

Key Points

• This research investigates the rapid enlargement of iatrogenic atrial septal defects due to tricuspid regurgitation jet impingement after mitral transcatheter edge-to-edge repair (M-TEER).
• Described cases of iatrogenic atrial septal defect expansion following M-TEER procedures.
• Focused on assessing the role of tricuspid regurgitation jet impingement in atrial compliance impairment.
• Notable rapid enlargement of iatrogenic atrial septal defects observed post-M-TEER due to TR-jet impingement.
• Prompt recognition of this complication is crucial for effective closure.
• Failure to manage effectively may lead to life-threatening outcomes.
