ABSTRACT: The diagnosis coronary artery disease is classically based on patient’s symptoms and morphology, as analyzed by angiography. The importance of risk factors for the development of coronary atherosclerosis and disturbance of coronary vasomoti…
Continued from previous page Acute myocardial infarction. Epicardial lesions related to acute myocardial infarctions are less than 50% in diameter in two-thirds of cases and less than 75% in diameter in more than 90% of cases,147,170,244 suggesting…
ABSTRACT: Background. Prevention of distal embolization during percutaneous coronary revascularization may be necessary to reduce post interventional morbidity and mortality. Methods. We employed a newly developed emboli containment and retrieval s…
ABSTRACT: Distal embolization after angioplasty in degenerated saphenous vein grafts (SVGs) results in high rates of periprocedural myonecrosis and mortality. Temporary protection of the distal microcirculation with aspiration of dislodged debris may…
ABSTRACT: Background. Stents provide effective treatment for stenotic saphenous venous aorto-coronary bypass grafts, but their placement carries a 20% incidence of procedure-related complications, which potentially are related to the distal embolizat…
ABSTRACT: Purpose. To evaluate the feasibility and safety of renal artery angioplasty and stenting utilizing a distal protection device to reduce the risk of intraprocedural atheroembolism. Methods. Twenty-eight hypertensive patients (18 men; mean ag…
ABSTRACT: Background. Fear of distal embolization and stroke has aroused concern regarding carotid stenting. Devices to protect the cerebral circulation may make carotid stenting safer. Methods. A multidisciplinary study group tested a balloon occl…
ABSTRACT: Purpose. To examine the possible beneficial effect of a new cerebral protection device based on balloon occlusion of the distal internal carotid artery (ICA) and debris aspiration for patients undergoing carotid artery stenting (CAS). Metho…
ABSTRACT: A coaxial catheter system for containment of distal embolization is described. Utilizing a novel 0.014" hypotube with a distal elastomeric occlusion balloon, the PercuSurge GuardWire functions as a guidewire while trapping distal embolizati…
ABSTRACT: Objectives. This study was designed to evaluate the composition and quantity of particulate debris resulting from vein graft intervention. Background. Distal embolization and “no reflow” are frequent and important complications resulting fr…
