Is It Ventricular Diverticulum or Closed Muscular Ventricular Septal Defect?

WEB—This is a Web exclusive article.
We have read the article by Srichai et al.
[1] with great interest. MDCT
coronary angiography has been the focus of our studies for a long time, and we
currently have several relevant publications in the literature
[2,
3]. In our routine cardiac MDCT
evaluations, we detected similar appearances to those in the Srichai et al.
study. Currently, we have a study under way focusing on this issue. It struck
our attention that the Srichai et al. study emphasizes that ventricular
diverticula may be seen in all locations except the interventricular
septum.

septal defect (VSD) localized to central septum. Axial (A) and sagittal

We further discussed these cases with a colleague who is a pediatric
cardiologist with clinical experience and interest in the topic. In his
evaluations, he stated that these appearances—particularly those related
to the septum, central, apical, or marginal muscular—were very similar
to those of small, closed muscular ventricular septal defects (VSDs) observed
in echocardiography and catheter angiography (Figs.
1A and
1B). Likewise, in our study,
the images we obtained from the study group revealed appearances of the septum
location similar to those in the Srichai et al.
[1] study.
We cannot tell whether those seen on the septum, for example on the apical
septum, are closed muscular VSDs or diverticula. Could those seen on the
septum, in particular, be the remains of closed muscular VSDs? If at least a
part of those seen in that location are of the remains of a closed muscular
VSD, this will affect the frequency of ventricular diverticula reported.
