Materials and methods: 182 consecutive Patients with drug refractory AF scheduled for PVI (62.6% male, mean age 64.1 +/- 10.2 years) underwent routine pre-procedural evaluation including transesophageal echocardiography (TEE) and CCTA for evaluation of left atrial (LA)/left atrial appendage (LAA) anatomy and thrombus formation. Qualitative and quantitative analysis (using aorta ascendens (AA)/LAA ratio) was performed. Measurements of the LA/LAA in LVES and LVED cardiac phase were obtained. Results: End-systolic volumes (LA/LAA) measured in 30 patients without filling defects as control group and all 14 with filling defects of 182 patients were significantly larger (p < 0.01) than in end-diastolic phase. Qualitative analysis was inferior to quantitative analysis using LA/LAA ratio (<0.5; accuracy: 100%, 88%, 100%, 99% vs 100%). 5 out of 182 patients (2.7%) showed thrombus formation of the LAA in CCTA confirmed by TEE and quantitative analysis.

Materials and Methods: A total of 182 consecutive patients with drug refractory AF scheduled for PVI (62.6 % male, mean age: 64.1 +/- 10.2 years) underwent routine diagnostic work including TEE and cardiac MDCT for the evaluation of LA/LAA anatomy and thrombus formation between November 2010 and March 2012. Contrast media injection was split into a pre-bolus of 30 ml and main bolus of 70 ml iodinated contrast agent separated by a short time delay. Results: In this study, split-bolus cardiac MDCT identified 14 of 182 patients with filling defects of the LA/LAA. In all of these 14 patients, abnormalities were found in TEE. All 5 of the 14 patients with thrombus formation in cardiac MDCT were confirmed by TEE. Conclusion: MDCT was 100 % accurate for thrombus, with strong but not perfect overall results for SEC equivalent on MDCT. Key Points: Patients with no filling defect or thrombus in MDCT in the LA/LAA region are unlikely to have thrombus and may undergo PVI without TEE. Here, the role of an additional TEE in pre-procedural management prior to PVI in patients with AF has to be redefined.

TTE and CMR were independently analysed regarding the presence of intracardiac thrombus formation, masses and related size, dimensions, shape and signal characteristics. TTE depicted intracavitary thrombus formation in 40/171 patients (23.4 %) and intracardiac mass in 12/171 patients (7.0 %). All masses revealed in TTE were correctly detected on CMR and confirmed by histology. However, CMR showed 15 additional thrombi and 3 additional intracardiac masses (p = 0.001) that were not seen in TTE. Patients with poor systolic function (LVEF < 30 %) had misleading results when referred to TTE (19 vs. 27 thrombi detected, p < 0.01). The detection of intracardiac masses or thrombi was not significantly different in patient with LVEF > 30 %, whereas CMR was superior when the LVEF was < 30 %. Routine TTE in patients with CAD leads to lower detection rates of intracardiac masses and thrombus formation in patients with severely impaired EF. Consequently we are missing a significant amount of clinically relevant diagnosis when only assessing patients with TTE.
