Classification of ventricular septal defects--a matter of precision.

Abstract

The classification of ventricular septal defects remains a contentious subject [1–6]. Hence, various authors will use different terms to describe septal defects. Regrettably, some of these terms lack precision in describing the anatomy and, thus, may give rise to different interpretations. This becomes particularly important when geographical differences in the distribution of various types of ventricular septal defects are considered. The use of the term subpulmonic ventricular septal defect may serve as an example.
