Anatomic measurements of atrial septal thickness suggest that difficulties in imaging the atrial septum during cross-sectional echocardiography are due to resolution limits of existing equipment.
Observational
Anatomic measurements of the atrial septum suggest that visualization difficulties in echocardiography are due to equipment resolution limits.
This anatomic study suggests that an understanding of the thickness of the atrial septum should allow better visualization of most portions of the blade-shaped atrial septum during cross-sectional echocardiography, both in normal subjects and in patients with ostium secundum atrial septal defects. The thickness measurements also demonstrate that difficulties in imaging the atrial septum are a function of resolution limits of existing echocardiographic equipment.
Rosenquist et al. (Mon,) conducted a observational in Ostium secundum atrial septal defects. Atrial septal thickness and area measurement was evaluated. Anatomic measurements of atrial septal thickness suggest that difficulties in imaging the atrial septum during cross-sectional echocardiography are due to resolution limits of existing equipment.
