Background and Objectives: Evidence regarding the efficacy and safety of intracardiac echocardiography (ICE) for guidance during transcatheter aortic valve replacement (TAVR) is limited. This study aimed to compare the clinical efficacy and safety of ICE versus transesophageal echocardiography (TEE) for guiding TAVR. Methods: This prospective cohort study included patients who underwent TAVR from August 18, 2015, to June 31, 2021. Eligible patients were stratified by echocardiographic modality (ICE or TEE) and anesthesia mode (monitored anesthesia care [MAC] or general anesthesia [GA]). Primary outcome was the 1-year composite of all-cause mortality, rehospitalization for cardiovascular cause, or stroke, according to the Valve Academic Research Consortium-3 (VARC-3) definition. Propensity score matching was performed, and study outcomes were analyzed for the matched cohorts. Results: Of the 359 eligible patients, 120 patients were matched for the ICE-MAC and TEE-GA groups, respectively. The incidence of primary outcome was similar between matched groups (18.3% vs. 20.0%; adjusted hazard ratio, 0.94; 95% confidence interval [CI], 0.53–1.68; p=0.843). ICE-MAC and TEE-GA also had similar incidences of moderate-to-severe paravalvular regurgitation (PVR) (4.2% vs. 5.0%; adjusted odds ratio, 0.83; 95% CI, 0.23–2.82; p=0.758), new permanent pacemaker implantation, and VARC-3 types 2–4 bleeding. Conclusions: ICE was comparable to TEE for guidance during TAVR for the composite clinical efficacy outcome, with similar incidences of moderate-to-severe PVR, new permanent pacemaker implantation, and major bleeding. These results suggest that ICE could be a safe and effective alternative echocardiographic modality to TEE for guiding TAVR.

<P><B>Abstract</B></P> <P>This study presents a direct and simple one-pot synthesis of 2-methylimidazole grafted poly-vinylbenzyl chloride (<SUP>2-Me</SUP>Im-pVBC) using radical polymerization, followed by its studies on the removal of structurally diverse mono and di-azo dyes (Acid Orange 7 (AO7), Acid Yellow 17 (AY17), and Acid Black 1 (AB1)) from aqueous media. Characterization of the material, effect of key factors such as dosage and pH on substrate removal, adsorption kinetics and isotherms, removal selectivity of the examined dyes, and reusability of the adsorbent were assessed. The prepared polymeric material exhibited outstanding removal activity with respect to all three dyes at a wide range of pH, with no significant impact due to the chemical complexity of the substrate. Adsorption kinetics and isotherm studies showcases supreme and rapid affinity towards AO7, with a maximum adsorption capacity of around 2012 mg/g. Lastly, <SUP>2-Me</SUP>Im-pVBC exhibited its sustainability by maintaining 8 cycles of adsorption-desorption process with outstanding substrate removal rate. Therefore, <SUP>2-Me</SUP>Im-pVBC demonstrated promising adsorption performance and exceptional selectivity on all three examined substrates, which can be further developed as an efficient agent for removing synthetic dyes in aqueous system.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Facile one-pot synthesis of imidazole-grafted polymer was performed. </LI> <LI> <SUP>2-Me</SUP>Im-pVBC exhibits superb removal of azo dyes from aqueous media. </LI> <LI> Adsorption capacities of the dyes depends on the electronic states of the dyes. </LI> <LI> <SUP>2-Me</SUP>Im-pVBC delineates high selectivity to azo dyes with high adsorption capacity. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
