Coronary Imaging


This study describes methods for crossing a severely stenotic aortic valve in light of modern imaging modalities (echocardiography, computed tomography, and fluoroscopy) and characterizes a successful crossing.
We analyzed patient radiation dose in 1786 cardiac catheterization procedures (diagnostic coronary angiography and/or PCI) performed at a single tertiary-care center before and after x-ray system optimization.
Radiopaque bypass graft markers allow easy visualization of the location of the graft and can minimize contrast use and radiation exposure during follow-up coronary angiography.
The objective of this study was to determine whether anatomical features of the aortic valve and aorta visualized by CT are predictive parameters of stroke.
The common cause of renal artery stenosis in young is fibromuscular dysplasia or Takayasu arteritis. Recanalized thrombus, on the other hand, is a rare cause for renal artery stenosis in young patients. OCT imaging confirmed the diagnosis and optimized the renal stenting results.
