From: A rare case of isolated persistent left superior vena cava diagnosed by echocardiography
A, B, C, D, E. Transthoracic echocardiography. A, B, C. Significantly dilated coronary sinus (arrows)- dimensions; parasternal long axis view- 2.3 × 1.4 cm (A), four-chamber view- 2.2 cm (B), two-chamber view- 2.9 × 1.7 cm (C). D, E. The injection of agitated saline into the right arm vein resulting in the opacification of a dilated coronary sinus followed by right atrial filling. F, G, H. CMR. Single-shot SSFP images, showing a single persistent left SVC (arrows), with the right-sided SVC missing in its typical position to the right and posteriorly from ascending aorta. F, G. The image from an axial stack. H. The coronal image CMR-cardiac magnetic resonance, SSFP-steady state free precession sequence, SVC-superior vena cava
