“…However, both papers were retrospective, while one of them included only a limited number of subjects and, in particular, neither of these two papers also evaluated the effect of the MDCT technique on performance, parameters and results of subsequent CA (7,10). The aims of our study were to provide a prospective, randomized, blinded comparison of MDCT image quality between the ECG-gated and helical non-gated techniques, comparison of the radiation dose between the two methods, and, since most centers prefer the MDCT of LA using ECG gating, an evaluation of the effect of MDCT data quality on the ablation process (13)(14)(15)(16)(17)(18)(19).…”

BACKGROUND: The impact of ECG gating during computed tomography (CT) acquisition of left atrium (LA) model on radiation dose, image quality and ablation event-free survival rate after catheter ablation (CA) of atrial fi brillation (AF) is not well defi ned. METHODS: Sixty-two patients with paroxysmal atrial fi brillation were randomized for two types of LA CT (with vs without ECG gating) before CA. Pulmonary veins isolation was performed in all patients. Patients were followed for 12 months after CA. RESULTS: There was no difference between the groups in CA length (131.61±32.57 vs 119.84±33.18 min; p=0.108), CA fl uoroscopy time (4.48±2.19 vs 3.89±1.83 min; p=0.251), CA fl uoroscopy dose (3.99±2.79 vs 3.91 vs2.91 Gy*cm2; p=0.735), visual data quality (1.77±0.88 vs 2.0±0.63; p=0.102) and registration error (2.42±0.72 vs 2.43±0.46 mm; p=0.612). We found a signifi cant difference in CT Dose index (89.55±5.99 vs 19.19±4.33 mGy; p<0.0001) and Dose Length product (1438.87±147.75 vs 328.21±73.83 mGy*cm; p<0.0001). Twelve months after CA, 25 of 31 patients in the gated group and 24 of 31 patients in the non-gated group were free of AF (80.65 vs 77.42 %; p=0.838). CONCLUSION: ECG gating of computed tomography of LA before AF ablation burdens patients with a four times higher radiation dose while improving neither the quality of CT model or fusion of CT with the electroanatomic map. As a result, it has no signifi cant impact on arrhythmia recurrence rate after ablation (Tab. 3, Fig. 3, Ref. 25). Text in PDF www.elis.sk.

“…Recently it has been proven that there are no significant movement of the oesophagus in the short term [ 25 ]. Based on this consideration, on the fact that CTA and MRA provide similar information before RFCA [ 29 ] and that the contrast-enhanced sequences seem to be highly sensitive and specific for diagnosing LA or LA appendage thrombus [ 30 ], a pre-procedural assessment based on an MRA with oral administration of concentrated pineapple for visualisation of the oesophagus a few hours before RFCA could represent the all-in-one pre-procedural imaging examination.…”

The purpose of this study was to compare in vitro pineapple juice and a solution of concentrated pineapple juice with a paramagnetic contrast agent in order to determine the feasibility of using the solution of concentrated pineapple juice in vivo for oesophagus visualisation at magnetic resonance angiography (MRA) before the radiofrequency catheter ablation procedure for atrial fibrillation. The pineapple juice was concentrated by a microwave heating evaporation process performed in a domestic microwave oven. Five grams of modified potato starch for every 40 mL of concentrated pineapple juice were added to the concentrated pineapple juice in order to thicken the solution. The solution resulted visually and quantitatively as hyperintense as the contrast agent in vitro (ratio = 1.02). in vivo, no technical difficulties were encountered during the MRA acquisition and a complete enhanced oesophagus was obtained in 37/38 patients (97.4%). The volumetric analysis and the three-dimensional reconstruction were feasible; the quality was rated as diagnostic in every patient. The intensified oesophagus was successfully merged into the electro-anatomical maps in all the patients. In summary, we demonstrated that this technique allows a feasible and safe oesophagus visualisation during MRA.
