Background: The classification of pulmonary stenosis severity based on the transpulmonary pressure gradient that is affected by flow rate.
Case Report: We report the first case of a pregnant patient with atrial septal defect and pulmonary stenosis that was misclassified by conventional echocardiographic methods. Most importantly, three dimensional transesophageal echocardiographic assessment of PS changed all treatment strategy.
Conclusion: The planimetric calculation of PV’s opening area using 3D TEE may be helpful especially in encounters with specialized conditions such as atrial septal defect or/and pregnancy, that can cause recordings of the transvalvular peak gradient to be inaccurate.
