Intracoronary imaging

Thrombotic complication during intracoronary imaging

Intracoronary imaging with intracoronary ultrasound and coherence tomography is often used in the follow-up of coronary stent implantation. The present case shows an infrequent complication of these procedures, suggesting our continued attention to the selective use of these invasive procedures.

Intracoronary imaging in chronic total occlusions

Chronic total occlusion (CTO) intervention constitutes approximately 10–20% of all angioplasty procedures at selected centers. Benefits of CTO revascularization, in addition to relief of angina, include improvement of left ventricular function, reduced risk of major adverse cardiac events and potentially increased survival. Although several techniques, devices and guidewires have been developed...

Clinical implications of intracoronary imaging in cardiac allograft vasculopathy.

Imaging of intracoronary thrombus by multidetector helical computed tomography angiography.

An 83-year-old woman presented to the emergency department with a 2-hour history of sudden chest pain and dyspnea. An initial ECG demonstrated nonspecific ST changes, and a portable chest x-ray suggested a widened mediastinum. A thoracic multidetector helical computed tomography (CT) angiogram was obtained to assess the possibility of aortic dissection (GE LightSpeed Plus, 2.5-mm collimation wi...

Intracoronary Imaging in the Detection of Vulnerable Plaques

Coronary artery disease is the result of atherosclerotic changes to the coronary arterial wall, comprising endothelial dysfunction, vascular inflammation and deposition of lipid-rich macrophage foam cells. Certain high-risk atherosclerotic plaques are vulnerable to disruption, leading to rupture, thrombosis and the clinical sequelae of acute coronary syndrome. Though recognised as the gold stan...
