Figure 17. Navigation inside left atrium and Implant deployment. DC positioned at level of anterior commissure: A: 3D overhead perspective; B: AP fluoroscopic projection; C: echocardiographic localization of circumflex artery; D: biplane imaging for fine tip positioning on the annulus and assessing the local angle of approach to the annulus; E: 3D MV en face view showing spatial relationships during deployment of first anchors in antero-lateral commissural area; F: multiplanar reconstruction showing anchor delivering; G: coronary angiography: spatial relationship between anchor (white arrow) and circumflex artery. DC: delivery catheter; AP: antero-posterior; MV: mitral valve
