Computed tomography angiography imaging of the Carillon device topography after unsuccessful treatment of functional mitral regurgitation

Figure 1. Imaging following unsuccessful Carillon device implantation. A) Transoesophageal echocardiography (TEE) at baseline, post Carillon implantation (post implant) and at nine-month follow-up (9-mo FU). B) Tracking the Carillon device (yellow line). C) MVA to Carillon device planes showing localisation of the device superior to the MVA. D) Aortic root (yellow line); AVP: aortic valve prosthesis; CS: coronary sinus (blue line); MVA: mitral valve annulus (red line). E) Left: topographical model indicating a Carillon device to MVA distance of 10.1 mm and a Carillon device to MVA angle of 18.3°. Right: AVP: aortic valve prosthesis, Carillon device plane vector (blue ...
