We aimed at investigating if per-operative advanced image processing can reduce patient and operator irradiation use during TAVI. We performed a prospective single-centre observational study comparing patient and operator radiation exposure using standard fluoroscopy (control group) or a novel technology of live advanced fluoroscopic image processing (test group) among consecutive patients undergoing TAVI between August 2015 and April 2016. Patient irradiation (dose-area product, effective dose and air kerma), contrast media volume and clinical outcomes were assessed. Among 152 elderly [median age (interquartile range): 83 (78-87)] patients (n = 76 per group) undergoing TAVI, baseline clinical characteristics were similar between the control and test groups, except for a higher median EuroSCORE II (2.8% vs 2.3%, P = 0.02) and higher rate of TAVI for failing surgical bioprosthesis (11.8% vs 2.6%, P = 0.03) in the control group. The dose-area product was reduced in the test group: mean reduction of -27.5 Gy × cm2 [95% confidence intervals (CIs): 15.9-39.1, P < 0.001]. Furthermore, effective dose [mean reduction -6.5 (95% CI: 5.9-7.2) mSv, P < 0.001] and air kerma [mean reduction -167.5 (95% CI 163.4-177.3) mGy, P < 0.001] were lower in the test group. Fluoroscopy time, contrast volume and clinical outcomes were similar. Patient radiation exposure was significantly reduced using a novel live advanced fluoroscopy image processing with calcification enhancement and fusion of the virtual aortic annulus without compromising patient safety.Show less >
