Innovations in imaging for chronic total occlusions: a glimpse into the future of angiography's blind-spot | European Heart Journal


Chronic total occlusions (CTOs) are a subset of lesions that present a considerable burden to cardiovascular patients. There exists a strong clinical desire to improve non-surgical options for CTO revascularization. While several techniques, devices, and guide ...

Comparison of vascular response to zotarolimus-eluting stent versus sirolimus-eluting stent: intravascular ultrasound results from ENDEAVOR III | American Heart Journal


The purpose of this study was to investigate the vascular response of zotarolimus-eluting stent (ZES) and sirolimus-eluting stent (SES) using serial intravascular ultrasound (IVUS)...

Assessment of coronary plaque collagen with polarization sensitive optical coherence tomography (PS-OCT) | International Journal of Cardiology


Current evidence indicates that most plaques classified as vulnerable or ruptured plaque do not lead to unstable angina or myocardial infarction. Improved methods are needed to risk stratify plaques to identify those which lead to most acute coronary ...

Intravascular Ultrasonic Analysis of Atherosclerotic Vessel Remodeling and Plaque Distribution of Stenotic Left Anterior Descending Coronary Arterial Bifurcation Lesions | The American Journal of Cardiology


Bifurcation lesions remain a challenging lesion subset, even in the era of drug-eluting stents. The aim of this study was to investigate the longitudinal remodeling pattern and cross-sectional plaque location of bifurcation lesions. Seventy-four preintervention intravascular ultrasound studies of left anterior descending bifurcation lesions were analyzed, in which the lesion was located proximal (type A, n = 32) or distal (type B, n = 42) to the side branch. Vessel area and plaque area at the lesion (VAlesion and PAlesion) and at the reference site (VAreference and PAreference) were measured...

Plasma low-density lipoprotein reduction and structural effects on coronary atherosclerotic plaques by atorvastatin as clinically assessed with intravascular ultrasound radio-frequency signal analysis | American Heart Journal


Plaque stabilization by statins is important for reduction of cardiovascular events but has not been demonstrated enough in vivo. We examined whether statins clinically alter the structure of coronary atherosclerotic plaques using intravascular ultrasound (IVUS) radio-frequency (RF) signal analysis...
