Example of an image from a patient with severe stenosis in the left anterior descending coronary artery. Panel 1: three dimensional volume rendering image, showing a severe lesion in the left anterior descending coronary artery (LAD, marked with an arrow). Panel 2: endoscopic view into the left main stem with visualisation of the LAD/left circumflex coronary artery bifurcation. Panel 3: proximal segment of LAD with vessel wall alterations but non-significant luminal narrowing. Panel 4: view at the severe lesion (on the left) and origin of the diagonal branch (on the right). Panel 5: view from inside the severe lesion into the vessel periphery of the LAD. Panel 6: axial slice image with navigator located in the left main stem. Panel 7: corresponding coronary angiography image, showing the severe LAD lesion. Panel 8: intracoronary ultrasound image within the severe non-calcified lesion.
