“…29,42, 44 The interventricular component of the membranous septum itself is also of interest, because if deficient, this is the site of the commonest variant of ventricular septal defect. 36 Its location is demonstrated with exquisite accuracy by virtual dissection (Figure 8, Right panel), which confirms that the ventriculo-infundibular fold crosses the interleaflet triangle on its right ventricular aspect, continuing anteriorly to form the posterior component of the supraventricular crest. The anterocranial component of the crest, anterior to the site of the right coronary aortic sinus, is then formed by the free-standing muscular infundibular sleeve ( Figure 5, Right panel).…”

“…The white open arrowheads in Figure b indicate the crest of the muscular ventricular septum adjacent to the membranous septum, known to be the location of the bundle of His. Additionally, the anatomical alignment from the membranous septum to the crest of the muscular ventricular septum, which is a frequent site of congenital ventricular septal defects, could be clearly imagined (Soto et al, ; Crucean et al, ).…”

“…), and then walls the aorta into the left ventricle. In the normal heart, the muscular outlet septum, if it exists, is very small and is located at the bifurcation between the anterosuperior and inferoposterior limbs of the septomarginal trabecula just beneath the right coronary aortic sinus (Lamers and Moorman, ; Webb et al, ; Anderson et al, ; Saremi et al, ; Crucean et al, ).…”

Cardiologists are increasingly becoming involved in procedures associated with the atrial septum and ventricular septum, such as transseptal puncture and selective site pacing. Moreover, detailed knowledge about the architecture of the atrial septum and ventricular septum is now available from studies by radiologists and anatomists. However, from the viewpoint of clinical cardiologists, many questions about the three-dimensional cardiac structural anatomy that relate closely to routine invasive procedures remain unresolved. Although modern multidetector-row computed tomography could provide answers, interventional cardiologists might have not considered the potential of this equipment, as only a few have performed studies with both radiological imaging and cadaveric hearts. Detailed knowledge of the three-dimensional fluoroscopic cardiac structural anatomy could help to reduce the need for contrast medium injection and radiation exposure, and to perform safe interventions. In this article, we present a series of cardiac structural images, including images of the atrial septum and ventricular septum, reconstructed in combination with the cardiac contour using multidetector-row computed tomography. We also discuss the clinical implications of the findings on the basis of accumulated insights of research pioneers. We hope that the present images will serve as a bridge between the fields of cardiology, radiology, and anatomy, and encourage cardiologists to integrate their accumulated insights into the three-dimensional clinical images of the living heart.

“…). And, because of the presence of the extensive free‐standing infundibular sleeve, there is no muscular septum between the two outlets (Crucean et al, ). Thus, the ventricular septum is almost totally composed of the apical muscular septum.…”

The heart is a remarkably complex organ. Teaching its details to medical students and clinical trainees can be very difficult. Despite the complexity, accurate recognition of these details is a pre‐requisite for the subsequent understanding of clinical cardiologists and cardiac surgeons. A recent publication promoted the benefits of virtual reconstructions in facilitating the initial understanding achieved by medical students. If such teaching is to achieve its greatest value, the datasets used to provide the virtual images should themselves be anatomically accurate. They should also take note of a basic rule of human anatomy, namely that components of all organs should be described as they are normally situated within the body. It is almost universal at present for textbooks of anatomy to illustrate the heart as if removed from the body and positioned on its apex, the so‐called Valentine situation. In the years prior to the emergence of interventional techniques to treat cardiac diseases, this approach was of limited significance. Nowadays, therapeutic interventions are commonplace worldwide. Advances in three‐dimensional imaging technology, furthermore, now mean that the separate components of the heart can readily be segmented, and then shown in attitudinally appropriate fashion. In this review, we demonstrate how such virtual dissection of computed tomographic datasets in attitudinally appropriate fashion reveals the true details of cardiac anatomy. The virtual approach to teaching the arrangement of the cardiac components has much to commend it. If it is to be used, nonetheless, the anatomical details on which the reconstructions are based must be accurate. Clin. Anat. 32:288–309, 2019. © 2019 The Authors.
