Cím:Cerebral microembolization during atrial fibrillation ablation : comparison of different single-shot ablation techniques / Alexandra Kiss, Edina Nagy-Balo, Gábor Sándorfi, István Édes, Zoltán Csanádi
Dátum:2014
ISSN:0167-5273
Megjegyzések:Background: Clinically silent cerebral ischemia (SCI) detected by diffusion-weighted MRI hasbeen reported in 5-40% of patients undergoing pulmonary vein isolation (PVI). Although initial reportssuggested a high rate of SCI with phased radiofrequency (RF) ablation on use of the pulmonary veinablation catheter (PVAC), the incidence was subsequently markedly reduced in consequence ofprocedural modifications in recent studies.We analyzed cerebral microembolization as assessed with transcranial Doppler during phasedRF ablation and with two other single-shot AF ablation technologies: the cryoballoon (CB) and thenMARQTM multipolar irrigated RF ablation system.Methods and results: A total of 89 patients (mean age: 57, SD: 12 years; 62 male) withparoxysmal or persistent AF, underwent PVI. Phased RF was used according to the initial protocol in 7patients (PVAC Group I), with procedural modifications and a newer (14.4) version of the RF generatorin 37 patients (PVAC Group II) and with the most recent (version 15.0) generator in 18 patients (PVACGroup III). Ablation was performed with the CB in 13 and with the nMARQ system in 14 patients.

Cím:Plaque volume derived from three-dimensional reconstruction of coronary angiography predicts the fractional flow reserve / Kolozsvári, R., Tar, B., Lugosi, P., Sánta, J., Béres, Z., Ungvári, T., Polgár, P., Kőszegi, Zs.

Megjegyzések:Objectives: to compare the data calculated from the three dimensional (3D) reconstruction of a coronary stenosis with the fractional flow reserve (FFR) values measured on the same coronary segment. Methods: Multiple projections of 22 patients (7 female, 15 male, age: 61?9,73 years ) were evaluated by the IC30 software of the Axiom Artis X-ray machine. 3D reconstruction was successfully carried out on 23 coronary arteries (14 LAD, 4 CX and 5 RCA). Results: Regression analysis demonstrated significant relationship between the cross-sectional area percentage stenosis (AS) calculated based on the 3D measurement and the FFR (r : -0,566, p: 0,008), as well as between the 3D derived plaque volume (PV) and the FFR (r : -0,501, p: 0,018). On the other hand, the diameter stenosis (DS) and the minimal lumen diameter (MLD) did not correlate with the FFR values. According to the Receiver Operating Characteristic (ROC) analysis the rank of the areas under the ROC curves (AUC) were the following: 1. PV (0.76), 2. AS (0.74), 3. DS (0.62), 4. MLA (0.55), 5. MLD (0.51). The difference between the AUC of the PV and MLA was found to be significant (p=0,02 ). The best agreement with the FFR was found when the PV was > 44% (sensitivity 66.67 %, specificity 82.35) and the 3D AS was >60% (sensitivity 100%, specificity 47 %). Conclusion: Beside the 3D AS the calculated PV characterizing the entire lesion is also an important predictor of the flow consequence of the stenosis.
