The conventional subtraction method (ECV-conv) requires dedicated pre- and post-contrast acquisitions, while the dual-energy spectral method (ECV-spec) uses only the post-contrast phase. We aimed to compare these methods in patients undergoing CT planning for transcatheter aortic valve replacement (TAVR).</p><p><strong>Methods: </strong>We prospectively included patients undergoing CT-TAVR evaluation on a dual-energy dual-layer detector scanner. Baseline pre-contrast and equilibrium delay phase (at 5 ​min) prospectively ECG-triggered acquisitions were co-registered for ECV-conv calculation. Equilibrium phase spectral iodine maps were derived for ECV-spec measurement and compared with ECV-con maps using a mid-septal and a global mid-ventricular region of interest.</p><p><strong>Results: </strong>Overall, 78 patients (53 ​% female, mean age 77 years) were analyzed. There was a minor overestimation in global measurement by ECV-spec (31.8 ​± ​4.6 ​% vs 30.3 ​± ​5.3 ​%, p ​= ​0.023. However, there were no significant differences between both methods for the mid-septal measurement (ECV-conv ​= ​30.4 ​± ​5.3 ​% vs ECV-spec ​= ​31.0 ​± ​5.6 ​%, p ​= ​0.196).).

Because of the nature of the guideline-recommended protocol -involving several different CCT acquisitions-it represents a unique dataset for comprehensive phenotyping of the patient with significant aortic stenosis. A substantial body of data has established CCT as a central tool in pre-procedural implantation planning. However, emerging evidence suggests a potential new role for CCT in phenotyping patient risk beyond the index procedure. This new role could represent a unique opportunity in patient selection, medication optimization and follow up post TAVR aiming to improve long-term prognosis.

Pediatric and adult congenital heart disease (ACHD) surgical programs require high quality CCT imaging as part of the multimodality imaging support expected of comprehensive care centers. Despite these expectations, there are no benchmarks or defined programmatic elements specific to the performance of CCT in patients with CHD. To address this deficit, this manuscript is written by a group of current CHD CCT practitioners and provides a collective opinion regarding the clinical components required, and essential resources needed, to deliver a comprehensive CCT CHD imaging program. Resource allocation was divided into CCT technology, imaging technologist, physician and programmatic support. The group is inclusive of pediatric and adult cardiologists and radiologists and includes practitioners from high and lower resourced programs and countries. Imaging settings are inclusive of academic and private practice, heart centers and combined radiology/cardiology service lines. Challenges and areas for future advocacy to support this growing specialty are proposed to improve performance standards that will consider the expected widespread variation in technical and staffing resources, skillsets, and practice settings for CT in CHD.</p><p><strong>Summary: </strong>High quality cardiovascular computed tomography is an essential component of pediatric and adult congenital programs and surgical centers. Program growth outpaces resource allocation in most institutions. This opinion paper outlines essential components for technical, technologist and physician resources and programmatic support to develop and maintain a successful CCT in CHD program. Although a small component of most cardiac imaging programs, it is an essential component particularly in complex cases. Institutional and imaging societal commitment is essential to support this emerging field at highest quality.</p>","PeriodicalId":94071,"journal":{"name":"Journal of cardiovascular computed tomography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143018934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
