However, there are no large studies or relevant literature specifically evaluating the use of MRA chest without and with IV contrast for preprocedural planning before cardioversion. MRA Chest Without IV Contrast There is no relevant literature to support the use of MRA chest without IV contrast to guide preprocedural planning for cardioversion. MRA Coronary Arteries Without and With IV Contrast There is no relevant literature to support the use of MRA coronary arteries without and with IV contrast to guide preprocedural planning for cardioversion. MRA Coronary Arteries Without IV Contrast There is no relevant literature to support the use of MRA coronary arteries without IV contrast to guide preprocedural planning for cardioversion. MRI Heart Function and Morphology Without and With IV Contrast There is emerging data that contrast-enhanced CMR is a reliable imaging modality for the detection of LA/LAA thrombus. A retrospective analysis of 97 patients showed 100% concordance in LAA thrombus detection between 3-D early postgadolinium enhancement CMR and TEE [50]. Another study comparing CMR with TEE in 261 patients showed a 99.2% diagnostic accuracy for long T1 delayed enhancement CMR in detecting LAA thrombi [28]. MRI Heart Function and Morphology Without IV Contrast There is limited data in the literature supporting the use of noncontrast CMR for detecting LAA thrombi. Kitkungvan et al [28] compared CMR with TEE for detecting LAA thrombi. SSFP cine MRI had a 91.6% diagnostic accuracy, a 66.7% sensitivity, and a 92.5% specificity. Flow-related breathing and inhomogeneity artifacts were the main causes for this lower yield. Left Atrial Procedures in Atrial Fibrillation SPECT or SPECT/CT MPI Rest and Stress There is no relevant literature to support the use of SPECT or SPECT/CT MPI rest and stress to guide preprocedural planning for cardioversion.
