AIMS Global angiographic scores have been developed to determine the extent of myocardium jeopardized by significant coronary stenosis. We adapted these scores to quantify the anatomic area at risk during acute myocardial infarction. We used contrast-enhanced magnetic resonance (CMR) infarct imaging to measure the portion of myocardium that developed(More)
RATIONAL AND OBJECTIVES We evaluated the ability of 64-slice computed tomography (CT), conventional cine-angiography, and intravascular ultrasound (IVUS) to detect stent fractures under ideal conditions. Coronary stent fracture has been implicated as one of the mechanisms of stent thrombosis and, perhaps, in-stent restenosis. However, the preferred imaging(More)
OBJECTIVE To determine the prognostic significance of creatine kinase (CK) elevation following elective percutaneous transluminal coronary angioplasty (PTCA). DESIGN Retrospective cohort study. SETTING Tertiary care referral center. SUBJECTS A total of 253 consecutive patients with total CK and CK-MB fraction (CK-MB) elevation (case patients) and 120(More)
BACKGROUND The geometrical accuracy of conventional three-dimensional (3D) reconstruction methods for intravascular ultrasound (IVUS) data (coronary and peripheral) is hampered by the inability to register spatial image orientation and by respiratory and cardiac motion. The objective of this work was the development of improved IVUS reconstruction(More)
BACKGROUND Unrecognized myocardial infarction (UMI) is known to constitute a substantial portion of potentially lethal coronary heart disease. However, the diagnosis of UMI is based on the appearance of incidental Q-waves on 12-lead electrocardiography. Thus, the syndrome of non-Q-wave UMI has not been investigated. Delayed-enhancement cardiovascular(More)
OBJECTIVES The purpose of this study was to investigate the correspondence between the coronary arterial anatomy and supplied myocardium based on the proposed American Heart Association 17-segment model. BACKGROUND Standardized assignment of coronary arteries to specific myocardial segments is currently based on empirical assumptions. METHODS A cardiac(More)
OBJECTIVES This study examined the contribution of symptom-to-reperfusion time, collateral flow, and antegrade flow in the infarct-related artery on myocardial salvage using a combined angiographic-cardiac magnetic resonance (CMR) method. BACKGROUND The myocardium supplied by an acutely occluded artery defines the anatomical area at risk for infarction.(More)
BACKGROUND Successful rehabilitation after ablative surgery requires not only the reconstruction of 3-dimensional form but also the restoration of physiologic function. OBJECTIVE To assess sensory recovery of reinnervated radial forearm flaps used for tongue reconstruction. PATIENTS AND METHODS Seventeen patients, who underwent reconstruction of(More)
A case of traumatic tricuspid insufficiency leading to right atrial enlargement and to a patent foramen ovale with right to left shunting is presented. Six similar cases previously reported are reviewed. The time course of clinical deterioration was related to the type of tricuspid valve damage incurred. Papillary muscle rupture led to surgery within a(More)
CONTEXT Limited data exist regarding use of drug-eluting stents outside of approved indications in real-world settings. OBJECTIVES To determine the frequency, safety, and effectiveness of drug-eluting stents for off-label (restenosis, bypass graft lesion, long lesions, vessel size outside of information for use recommendation) and untested (left main,(More)
