Due to the complex anatomy preprocedual imaging is frequently performed before catheter intervention for pulmonary vein isolation. With the advent of electrocardiogram-gated and respiratory-gated 3D steady state free precession sequences covering the entire heart (whole-heart MR angiography) it has become possible to visualize cardiac vascular anatomy with high spatial resulution using MR imaging. The hypothesis for this study was that the intravascular contrast medium gadofosveset trisodium improves image quality of whole-heart MR angiography and hereby allows excellent visualisation of left atrium and pulmonary veins.
