1. Study accessory bands within cardiac chambers and differentiate them from normal muscular bands, accessory chordae tendineaea and papillary muscles 2. Discuss pathological bands and membranes affecting heart  3. Illustrate imaging appearance of these conditions on MDCT and MRI  

The number, size and morphology of chordae tendineae and papillary muscles is variable. Accessory bands may be asymptomatic incidental findings or can be associated with congenital heart diseases. Their  radiological appearances is similar to that of normal muscular bands. However at times they may be pathological and can cause with hemodynamic alterations with adverse clinical implications.They can restrict mobility and cause outlet obstruction. Ruptured accessory chordae tendinae can cause regurgitation. Echocardiography, CT scan and MRI can be used for evaluation of accessory bands. Radiologists should know the advantages and limitations of each imaging modality. They should be familiar with the imaging appearances of these bands and understand their clinical significance. In this educational exhibit, we discuss • Introduction • Anatomy and anatomic variants • Accessory bands, chords, tendons and membranes in the Heart • Pathological conditions • Cross-sectional imaging findings & role of imaging • Clinical implications • Conclusion
