Insights
Doppler echocardiography revealed an abnormal atrial shunt flow velocity pattern in a patient with an iatrogenically created atrial septal defect. This finding predicted a high transatrial pressure gradient, confirmed later by catheterization.
Area of Science:
- Cardiology
- Echocardiography
- Interventional Cardiology
Background:
- Iatrogenic atrial septal defects can occur during cardiac procedures.
- Accurate assessment of shunt hemodynamics is crucial for patient management.
Abstract:
An unusually high atrial shunt flow velocity pattern was recorded in a patient whose atrial septal defect was created iatrogenically during a transatrial septal approach to aortic valvuloplasty. The flow velocity pattern measured by Doppler echocardiography was predictive of the high transatrial pressure gradient noted later at catheterization.
