Percutaneous coronary intervention (PCI) for unprotected left main truncus (LMT) lesions is controversial. Inoperable status with advanced age, renal dysfunction, frailty, or patient request may require an unprotected left main PCI. PCI for LMT is not recommended in the typical clinical situation; however, when it is the only feasible option, the performance is not bad. We demonstrated the result of a cobalt-chromium everolimus-eluting stent (CoCr-EES) in the LMT stenting and serial changes via micro-computed tomography (μCT). μCT is an established imaging technique used for high-resolution, non-destructive assessment of vascular samples. The technique has drawn increasing interest for investigations of atherosclerotic arteries in both humans and animal models. There are no reports regarding the linkage between clinical results and μCT images.

Unprotected left main intervention for surgery-ineligible patients with coronary artery disease-Usefulness of micro-CT images for stent.

Transluminal-attenuation-gradient (TAG) may reflect patient characteristics and physiological parameters. Furthermore, TAG may be affected by factors such as the CT scanner speed, scanning method, scan timing after contrast-medium (CM) injection, and the injection methods. The purpose of our study was to investigate quantitative TAG at different scan timing points after CM injection for coronary CT angiography.

Transluminal attenuation-gradient coronary CT angiography on a 320-MDCT volume scanner: Effect of scan timing, coronary artery stenosis, and cardiac output using a contrast medium flow phantom.

Collateral arteries provide an alternative blood supply and protect tissues from ischemic damage in patients with peripheral artery disease. However, the mechanism of collateral artery development is difficult to validate.
