Histopathologic validation of angioscopy and intravascular ultrasound.

BACKGROUND To establish a histopathologic basis for angioscopic and ultrasound image interpretation we studied 70 postmortem human arterial segments in vitro. METHODS AND RESULTS We used 7- to 9-French fiber-optic angioscopes and 20- to 30-MHz intravascular ultrasound imaging catheters. Three observers assigned an angioscopic and ultrasound image classification to each vessel segment. The ima...

Mechanical and structural characteristics of vulnerable plaques: analysis by coronary angioscopy and intravascular ultrasound.

OBJECTIVES Mechanical and structural characteristics of vulnerable plaques were evaluated using coronary angioscopy and intravascular ultrasound. BACKGROUND Mechanical stress and composition of plaques play an important role in plaque disruption. METHODS Thirty-eight lesions in 38 patients were examined pre-interventionally. The plaques were classified as either yellow or white using corona...

Plaque Regression and Stability Evaluated by Intravascular Ultrasound and Coronary Angioscopy: A Review

Although atherosclerosis seems to be continuously progressive and irreversible, it has been being demonstrated that substantial regression or stabilization of atherosclerotic lesions can occur by some interventions improving its determinants. However, the concepts of plaque regression or stabilization are not so new. It has been reviewed that the first reported observation of plaque regression ...

Unique single coronary artery with acute myocardial infarction: observation of the culprit lesion by intravascular ultrasound and coronary angioscopy.

We report an acute myocardial infarction in a patient with a single coronary artery. The right coronary artery arose from the middle portion in the left anterior descending artery through the transverse branch. This type of single coronary artery has not been previously reported. Moreover, this is the first report in which the culprit lesion in a patient with a single coronary artery was observ...

Diverse Findings in Calcified Thrombus Between Histopathology and In Vivo Imaging Including Intravascular Ultrasound, Optical Coherence Tomography, and Angioscopy.

A 46-year-old woman on hemodialysis due to end-stage renal disease was admitted for repeated thrombus formation in previously implanted drug-eluting stents in the right coronary artery. We could successfully aspirate this thrombus, and histopathology revealed a calcified thrombus comprising multiple microcalcifications and fibrinous materials. This is the first report showing how a calcified th...
