“…In the literature, it has been reported that the right septomarginal trabecula extends between the septum—outer wall (Evans & De Lahunta, 2013; Nascimento et al, 2019; Ravindran & Victor, 1982) septum—anterior papillary muscle (Ghonimi et al, 2015; Kosinski et al, 2010; Leao et al, 2010; Nascimento et al, 2019; Raghavendra et al, 2013), anterior papillary muscle—outer wall (Arıncı & Elhan, 2014; Ateş & Çakır, 2010; Cope, 2016b; Evans & De Lahunta, 2013), and septal papillary muscle—anterior papillary muscle (Ates et al, 2017; Gulyaeva & Roshchevskaya, 2012; Perez et al, 2018). In our study, it was determined that the right septomarginal trabecula extended between the septal papillary muscle and the anterior papillary muscle.…”

“…In humans (Ravindran & Victor, 1982), it was determined that these trabeculae crossing the ventricular cavity were located vertically in 20 hearts. In a study (Ravindran & Victor, 1982), it was detected that the septomarginal trabeculae were short and thick or long and thin. Loukas et al (2010) stated that septomarginal trabeculae were classified as ‘short and thick’ in 42 hearts, ‘short and thin’ in 24 hearts, ‘long and thick’ in 12 hearts, ‘long and thin’ in 14 hearts, and they could not be identified in 8 hearts.…”

This study was conducted to reveal the anatomical and histological features of left and right septomarginal trabeculae in the heart of the Hatay mountain gazelle. In the study, two female and two male adult Hatay mountain gazelle hearts were used. For this purpose, the materials detected in 10% formaldehyde solution were stained with Crossman's modified triple staining technique and examined under a light microscope after anatomical examinations and measurements were made. The presence of trabeculae in both ventricles was demonstrated. While the number of septomarginal trabeculae was 1 in each of the samples in the right ventricle, it was determined that it was 2 in each of three hearts and 3 in one heart in the left ventricle. It was observed that the right trabeculae were unbranched and fleshy, while the left trabeculae were filamentous and mostly branched. The lengths and thicknesses of the right trabeculae were measured 12–17 mm and 3–4 mm and the lengths and thicknesses of the left trabeculae were measured 6–15 mm and 0.5–1 mm. In the histological examination of both trabeculae, connective tissue, Purkinje fibres and blood vessels were observed, in addition, it was detected that the right trabeculae had myocardial fibres. Few capillaries were found in the left trabecula, while both more capillaries and blood vessels were found in the right trabeculae.

“…Usually there is a single band, but occasionally two bands are depicted, with either a simple or complex branching attachment to the papillary muscles (41). It is usually transverse in orienta-tion but occasionally can be vertical (37). In the transverse plane, it is more often located in the mid-(47%) (Fig 8b) or apical (40%) (Fig 8c) region of the RV than in the basal portion near the tricuspid valve (27).…”

“…The moderator band is a prominent muscular ridge in the RV, present in up to 92% of patients (27,37,38). It was first described by Leonardo da Vinci as the "catena of the right ventricle" (27) and termed the moderator band in 1937 owing to its perceived role in preventing overdistention of the RV (27,39).…”

Bands in the Heart: Multimodality Imaging Review

Multiple bands and bandlike structures can be found within the cardiac chambers, which can be evaluated with various imaging modalities including echocardiography, CT, MRI, and invasive angiography. These bands can be classified as normal structures or normal variants, aberrant structures, or pathologic entities. Normal structures include the crista terminalis, taenia sagittalis, Chiari network, coumadin ridge, moderator band, papillary muscles, and chordae tendineae. Aberrant structures include aberrant papillary muscles, accessory chordae, false tendons, and accessory mitral valve tissue. Pathologic entities include double-chambered right ventricle, double-chambered left ventricle, cor triatriatum, and subaortic stenosis. Several types of bands are incidental findings discovered at imaging and do not produce clinical symptoms. However, some bands can mimic cardiac diseases, including masses. More importantly, some bands are pathologic entities that produce symptoms owing to hemodynamic consequences. Performing multimodality imaging helps the radiologist (a) identify, localize, and characterize the bands; (b) determine if they are normal structures, abnormal structures, or pathologic entities; (c) distinguish them from cardiac pathologic conditions; and (d) evaluate the secondary consequences of pathologic entities. This article reviews the various bands visualized within the cardiac chambers, as well as the role of imaging in depicting the bands, their appearances across various imaging modalities, and their clinical significance.

Advances in computed tomography have led to continuous improvement in cardiac imaging. Dedicated postprocessing capabilities, faster scan times, and cardiac gating methods reveal details of normal cardiac anatomy and anatomic variants that can mimic pathologic conditions. This article will review normal cardiac anatomy and variants that can mimic disease. Radiologists should be familiar with normal cardiac anatomy and anatomic variants to avoid misinterpretation of normal findings for pathologic processes.
