Percutaneous Coronary Angioscopy.

Percutaneous coronary angioscopy.

Morphologic changes in the coronary arteries of patients with ischemic heart disease were evaluated by angiography. Although a powerful diagnostic tool, angiography can show only the shadow of the luminal changes and therefore is an insufficient tool for diagnosis of pathological changes. Recent advances in fi beroptic technology now enable observation of the luminal changes even in small diame...

Percutaneous Transluminal Angioscopy During Coronary Intervention

To investigate the feasibility of angioscopic-guided percutaneous transluminal coronary angioplasty and to elucidate the mechanism of efficacy of coronary stenting for acute myocardial infarction, we performed coronary angioscopy in 102 patients with stable angina or acute myocardial infarction. Thrombi and intimal flaps were observed in most patients after coronary angioplasty. Large intimal s...

The development and clinical feasibility of percutaneous transluminal coronary angioscopy.

Virtual coronary angioscopy using multislice computed tomography.

BACKGROUND With faster image acquisition times and thinner slice widths, multislice detector computed tomography (MSCT) allows visualisation of human coronary arteries with diagnostic image quality. In addition to conventional axial slices, virtual coronary angioscopies (VCA) can be reconstructed using MSCT datasets. OBJECTIVE To evaluate the feasibility of reconstructing VCA and to determine...

Dye-Staining Angioscopy for Coronary Artery Disease

Novel imaging techniques using biomarkers have clarified the mechanisms of hitherto unanswered or misunderstood phenomena of coronary artery disease and enabled evaluation of myocardial blood and tissue fluid flows in vivo. Dye-staining coronary angioscopy using Evans blue (EB) as the biomarker can visualize fibrin and damaged endothelial cells, revealing that the so-called platelet thrombus is...
