Improved Visualization of Heart Valves With 4D-CT Using a Novel Motion Correction Algorithm

OBJECTIVE: Motion artifacts remain a limitation of cardiac CT when assessing both native and prosthetic heart valves, particularly during phases of rapid motion. This may lead to reduced image quality, potentially impairing the evaluation of valvular movement and pathology. The p...

Cardiac Myosin‐Binding Protein C for Diagnosis of Myocardial Infarction in Patients With Prior Coronary Artery Bypass Grafting

Background Diagnosing myocardial infarction in patients with prior coronary artery bypass grafting (CABG) remains challenging, primarily because of lower diagnostic accuracy of high‐sensitivity cardiac troponin (hs‐cTn). cMyC (cardiac myosin‐binding protein C), because of its fas...

Timing of PCI in Patients Undergoing Transcatheter Aortic-Valve Implantation

BackgroundApproximately one half of patients undergoing transcatheter aortic-valve implantation (TAVI) have concomitant coronary artery disease. Although percutaneous coronary intervention (PCI) is often performed before TAVI, the preferred treatment strategy has not been establi...

Improving image quality by reducing breathing artifacts in CT of patients early after coronary artery bypass graft surgery

Abstract The purpose of this study was to evaluate whether a misalignment correction algorithm reduces artifacts from breathing in patients undergoing computed tomography angiography (CTA) early after coronary artery bypass graft (CABG) surgery. In this retrospective study, conse...
