Examples of imaging the coronary artery-aortic graft anastomotic site using transthoracic echocardiogram (TTE) and multi-detector computed tomography (MDCT). A, an off-axis TTE acoustic window derived from the parasternal short-axis view of the right coronary artery (RCA) ostium of patient no.1 at the coronary-aortic graft anastomotic site (patient no.1) and B, visualization of the RCA using MDCT of the same patient (no.1); C, an off-axis TTE acoustic window derived from the parasternal short-axis view of the left main coronary artery (LMA) ostium of patient no.3 at the coronary-aortic graft anastomotic site and D, image of the LMA ostium using MDCT on the same patient (no.3). AscAo, ascending thoracic aorta. All vessel diameters were measured at the coronary ostial-aortic graft junction for both MDCT and TTE imaging techniques.
