management in AF ablation [5,6]. So far limited data are available on the incidence of VTEs after AF ablation among patients receiving periprocedural anticoagulation with DOACs. The present study aimed to investigate the incidence of symptomatic deep vein thromboses (DVTs) and pulmonary thromboembolisms(PTEs) among patients who underwent catheter ablation of AF and received periprocedural DOAC treatment. Methods Study Population This retrospective observational study enrolled 2,193 consecutive AF patients who received periprocedural oral anticoagulation with DOACs prior to AF catheter ablation at Gunma Prefectural Cardiovascular Center between April 2011 and April 2018. All patients underwent transthoracic echocardiography to evaluate the atrial and ventricular sizes and left ventricular function using standard parasternal and apical views before the procedure, and transesophageal echocardiography to rule out any intracardiac thrombi on the day of the procedure or the day before. Written informed consent for the electrophysiological study and catheter ablation of AF was obtained

Objectives To evaluate the accuracy of direct computed tomographic venography (DCTV) and duplex ultrasound (DUS) in the identification of iliac vein obstruction in highly symptomatic patients with severe chronic venous disease (CVD) compared with intravascular ultrasound (IVUS). Methods this study involved patients who had advanced CVD (CEAP C3-6). All patients underwent DCTV, venous duplex scanning, and IVUS. The presence of iliac vein obstruction was detected, and degree of obstruction was classified into 3 grades (grade I, 0% to 49%; grade II, 50% to 79%; and grade III, 80% or greater). The sensitivity, specificity, PPV, NPV, and accuracy were calculated for each modality compared with IVUS. Inter-observer agreement was assessed using the κ coefficient Results of 94 patients with CVD, IVUS identified iliac vein obstruction in 55 (58.5%) patients (25.5% was grade 1, 27.3% was grade 2, 47.3% was grade 3). The sensitivity, specificity of DCTV in diagnosing obstruction was (96%, 95% in grade 1; 100%, 100% grade 2; 100%, 100% in grade 3, respectively). The sensitivity, specificity of DUS was (63.9%, 65% in grade 1; 68%, 82% in grade 2, and 70%, 85% in grade 3, respectively). The overall agreement of DUS was 0.73 (95% CI, 0.70–0.79), and DCTV was 0.96 (95% CI, 0.91– 0.97). Conclusions DUS is a reasonable initial imaging modality for the identification of significant iliac vein obstruction. DCTV provides an accurate reproducible imaging for accurate estimation needed for treatment planning. Advances in knowledge Direct CT Venography provides accurate reproducible radiological information required for treatment planning of patients with Iliac vein obstruction including accurate assessment of site of obstruction, its morphology, and degree of obstruction and it can replace the use of indirect CT venography using smaller amount of contrast media with accurate diagnosis.
