This study aimed to assess the radiation dose and image quality of CCTA using PCD-CT, combined with high-pitch helical scanning and an ultra-low tube potential of 70 kVp, and investigate the effect of a sharp kernel on image quality and stenosis assessment in such an ultra-low-dose CCTA setting.</p><p><strong>Methods and results: </strong>Forty patients (65% male) with stable heart rates and no prior coronary interventions were included. Data on CT dose index volume (CTDIvol) and dose-length product (DLP) were collected, with effective radiation dose estimated using a conversion factor of 0.014. Images were reconstructed using kernels of Bv64 and Bv40 for image quality and stenosis assessment. The mean CTDIvol, DLP, and effective dose of CCTA were 1.72 ± 0.38 mGy, 29.1 ± 6.8 mGy·cm, and 0.41 ± 0.09 mSv, respectively. Image quality was similar (<i>P</i> = 0.75) between the two kernels, with over 95% of segments achieving a rating of good image quality for both kernels. The per-segment stenosis score distribution between Bv40 and Bv64 reconstruction images showed significant differences for both non-calcified and calcified plaques (<i>P</i> < 0.001 for both).</p><p><strong>Conclusion: </strong>PCD-CT technology with high-pitch helical scanning and the tube potential of 70 kVp can provide CCTA with ultra-low radiation exposure (DLP, 29 mGy·cm).

PAD and aortic conditions contribute significantly to global cardiovascular morbidity and mortality; yet, they are often underdiagnosed and undertreated. Imaging plays a critical role in addressing this gap, with the European Society of Cardiology and American Cardiac Society offering different approaches to diagnostic and interventional imaging modalities. The review highlights that while both guidelines endorse duplex ultrasound as the first-line imaging method for PAD, discrepancies arise in the use of advanced modalities such as computed tomography angiography and magnetic resonance angiography. The European guidelines adopts a more conservative approach, reserving these advanced techniques for specific clinical scenarios, whereas the American guidelines places a stronger emphasis on comprehensive imaging for all patients with suspected PAD. The review also compares the guidelines on aortic disease, noting consensus on the role of computed tomography angiography and magnetic resonance angiography for aortic aneurysm diagnosis, but with differences in the emphasis on transoesophageal echocardiography, which is more strongly recommended by the American guidelines for acute cases. The manuscript calls for harmonization of these guidelines to streamline clinical practice and improve patient outcomes.</p>","PeriodicalId":94317,"journal":{"name":"European heart journal.

Whether routine assessment of CAD by invasive coronary angiography (CA) and eventual peri-procedural percutaneous coronary intervention (PCI) is generally beneficial in TAVI patients has recently been heavily questioned. CA carries significant risks, such as kidney injury, bleeding, and prolonged hospital stay, and may frequently be unnecessary if significant stenoses of the proximal coronary segments can be ruled out on computed tomography angiography. Moreover, the benefits of pre-emptive coronary revascularization at the time of TAVI are not well defined.
