As non-invasive cardiac imaging is evolving into an ever more important medical field, the introduction of this new technology promises a slew of improvements over energy-integrating detector (EID)-CTs, most importantly improved spatial resolution in the form of ultrahigh-resolution (UHR) imaging, reduced radiation exposure, and routinely acquired spectral information. Spatial resolution has historically been a key hurdle for cardiac CT, especially for coronary imaging where structures in the realm of 2 mm need to be assessed. Initial reports on the use of PCD-CT in cardiac imaging so far have been promising, but many questions ranging from standardized scan protocols to evidence-based recommendations remain.

A study by Zach et al. (2024) demonstrated the feasibility of this technique in 64% of patients, offering a viable alternative when 3D echocardiography is unavailable or non-diagnostic. The study found no significant correlation between lead position and TR severity, suggesting that other factors may contribute to TR development. While the subcostal en face view holds significant promise, limitations such as poor image quality in patients with obesity, abdominal pathologies, or multiple leads, as well as the need for experience to maximize success rates, must be addressed. Future prospective studies are needed to validate the clinical benefits of the subcostal en face view during CIED implantation, including its impact on procedural duration and TR prevention.
