Morphologic and angiographic features of coronary plaque rupture detected by intravascular ultrasound.
OBJECTIVES This study was designed to report the clinical and angiographic correlates of plaque rupture detected by intravascular ultrasound (IVUS). BACKGROUND Acute coronary syndromes result from spontaneous plaque rupture and thrombosis. METHODS We report 300 plaque ruptures in 257 arteries in 254 patients. Plaque ruptures were detected during pre-intervention IVUS. Standard clinical, ang...
متن کاملSpontaneous plaque rupture and thrombus formation in the left main coronary artery documented by intravascular ultrasound.
This case documents the finding of a spontaneous plaque rupture with thrombus formation in the left main coronary artery of a patient who presented with an infarction of the circumflex artery. This serendipitous observation supports the hypothesis that spontaneous plaque ruptures occur sporadically and do not necessarily lead to occlusion.
متن کاملLongitudinal visualization of spontaneous coronary plaque rupture by 3D intravascular ultrasound.
A60-year-old man, 4 years after an anterior myocardial infarction at the middle segment of the left anterior descending coronary artery (LAD), underwent coronary angiography (CAG) because of severe continuous chest pain for .3 hours 3 weeks earlier. CAG revealed no significant stenosis but showed a wall fissure with a double-contrast opacification at the proximal segment of the LAD (short arrow...
متن کاملThe site of plaque rupture in native coronary arteries: a three-vessel intravascular ultrasound analysis.
OBJECTIVES We evaluated the axial location of plaque ruptures in native coronary arteries. BACKGROUND It is clinically important to understand the potential sites of plaque rupture. METHODS We performed three-vessel intravascular ultrasound (IVUS) examination in 392 patients; 231 had acute coronary syndrome (ACS) and 161 had stable angina pectoris (SAP). The IVUS detected plaque ruptures in...
متن کاملGlobal characterization of coronary plaque rupture phenotype using three-vessel intravascular ultrasound radiofrequency data analysis.
AIMS To compare the global characteristics of patients with and without evidence of plaque rupture (PR) in their coronary tree and to evaluate the phenotype of ruptured plaques using intravascular ultrasound (IVUS) radiofrequency data analysis (IVUS-VH). METHODS AND RESULTS Forty patients underwent three-vessel IVUS-VH interrogation. Twenty-eight PRs were diagnosed in 26 vessels (25.7% of the...
