Why the study?
Is the right atrial appendage wall significantly thinner than the right atrium wall, and does this predispose it to rupture in blunt trauma?
Population
1 case of isolated right atrial appendage rupture in blunt trauma, 8 cases from literature review, and…
Comparison
Anatomic measurement of right atrium and right… vs RA wall thickness versus RAA wall thickness

Thinner RAA wall does not explain blunt trauma rupture risk; leaves open primary determinants for study.
Is the right atrial appendage wall significantly thinner than the right atrium wall, and does this predispose it to rupture in blunt trauma?
Although the right atrial appendage is significantly thinner than the right atrium, anatomic wall thickness does not appear to be the primary determinant for rupture in blunt cardiac trauma.
Figueiredo et al. (2007) studied this question.
