Plaque rupture as a cause of apparent coronary aneurysm formation following directional coronary atherectomy.
نویسندگان
چکیده
Late coronary aneurysm formation was observed following treatment by directional coronary atherectomy. Intravascular ultrasound disclosed that the mechanism involved was plaque rupture. The cause of coronary aneurysm may be multifactorial after coronary interventions. Intravascular ultrasound imaging is useful for understanding the pathologic mechanism of coronary aneurysm production.

Relation of deep arterial resection and coronary artery aneurysms after directional coronary atherectomy.
OBJECTIVES The aims of this study were to document the frequency of coronary artery aneurysm formation in patients undergoing directional coronary atherectomy and to determine the relation of such aneurysms to the depth of arterial resection. BACKGROUND Deep arterial injury is relatively frequent with the use of directional coronary atherectomy, but the potential for subsequent coronary arter...

Higher levels of tissue factor (the initiator of blood coagulation) have been found in coronary atherosclerotic plaques of patients with unstable coronary artery disease, but it is not established whether they are associated with a different thrombotic response to in vivo plaque rupture. In 40 patients undergoing directional coronary atherectomy, prothrombin fragment 1 1 2, a marker of thrombin...
متن کاملTreatment of an ostial and a bifurcation lesion with a new directional atherectomy device.
Two cases of directional coronary atherectomy performed with a new 8 French monorail device for selective plaque excision are illustrated. This report underlines the technical characteristics of this new device, which allows the negotiation of complex coronary anatomy and emphasises the potential utility of directional coronary atherectomy in bifurcation and ostial lesions.
