1/59. Multiple coronary occlusions associated with ST-segment elevation.We describe the case of a patient with rapid sequential ST-segment elevation in different areas on the electrocardiogram (ECG) associated with lesions of differing etiologies in the corresponding coronary arteries. Prior reports of ST-segment elevations in multiple areas on the ECG have been from obstructions of single coronary vessels whose distribution overlapped separate areas on the ECG or spasm of multiple coronary arteries. We could find no prior reports of such rapid sequential ST-elevation in different areas on the ECG caused by two differing etiologies.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/59. Successful stenting on tortuous coronary artery with accordion phenomenon: strategy--a case report.Guidewire manipulation through tortuosities is difficult. Straightening a tortuous coronary artery by using a stiff guidewire has been recognized to induce vessel wall shortening referred to as an "accordion phenomenon." With inappropriate identification as dissection or thrombus formation, the risk of performing unnecessary dilation at the pseudo-narrowing site exists. The authors describe here two cases showing the accordion phenomenon induced by a stiff guidewire during successful stenting at a tortuous right coronary artery. In another case, the authors experienced an "accordion phenomenon" at the proximal edge of the Palmaz-Schatz stent implanted in a tortuous right coronary artery. The stent edge was better positioned at the straight portion than at the contour portion in a tortuous coronary artery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/59. Successful dissolution of occlusive coronary thrombus with local administration of abciximab during PTCA.Treatment of intracoronary thrombus poses difficult problems and may result in severe complications. We used a local delivery catheter (InfusaSleeve, LocalMed, Palo Alto, CA) to treat an occlusive coronary thrombus that was refractory to systemic thrombolysis and conventional angioplasty. After local administration of 10 mg of abciximab with this catheter there was successful resolution of coronary thrombus and vessel recanalization. Cathet. Cardiovasc.

4/59. A 42-year-old man with recurrent myocardial infarction and normal appearing coronary arteries.We report the occurrence of a coronary mural thrombus and recurrent myocardial infarction in a patient with normal-appearing epicardial coronary arteries and small-vessel coronary artery disease. The current case emphasizes the importance of permanent medical treatment with anti-platelet and vasodilators in patients with small-vessel coronary artery disease.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
5/59. Double vessel occlusions after balloon angioplasty treated by stenting and subsequently by abciximab infusion.Stent thrombosis is a serious complication after percutaneous coronary intervention. A patient is presented with a double vessel occlusion after balloon angioplasty and subsequent stenting. He was then managed by abciximab therapy alone. Control angiography showed complete resolution of the thrombotic occlusions. His subsequent clinical course was uneventful.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
6/59. Tortuous internal mammary artery angioplasty: accordion effect with limitation of flow.Mechanical straightening of a tortuous vessel during angioplasty has been well described. It can be mistaken for thrombus, dissection or spasm. This report presents a case in which straightening of vessel due to stiff guide wire results in accordion effect and flow limitation.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
7/59. Transluminal extraction catheter atherectomy for the treatment of acute occlusion of an ectatic coronary artery.Thrombotic occlusion of an ectatic coronary artery may not respond to thrombolytic therapy or balloon angioplasty, since the infarct-related vessel contains a significant amount of thrombus. A patient with acute myocardial infarction of an ectatic right coronary artery that was occluded by a heavy clot burden is described. The patient was treated successfully with transluminal extraction catheter atherectomy and results were confirmed by intravascular ultrasound.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/59. Multivessel coronary thrombosis, acute myocardial infarction, and no reflow in a patient with essential thrombocythaemia.Essential thrombocythaemia (ET) has been reported rarely to cause coronary thrombosis, but the management is still undefined. A 63 year old woman with multivessel coronary thrombosis, acute myocardial infarction (MI), and no reflow in reperfused coronary artery in association with ET is presented. The patient's platelet count was only moderately raised at the onset of MI, but peripheral blood smear and bone marrow evaluation revealed clumping giant platelets and numerous large hyperploid megakaryocytes. Long term prophylaxis with antiplatelet agents in patients with ET is recommended, even if the platelet count is not largely raised. Cytoreductive treatment may also be effective for secondary prevention when thrombotic complications occur.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
9/59. myocardial infarction with acute thrombosis of multiple major coronary arteries: a clinical and angiographic observation in four patients.Four patients are reported in whom concomitant obstructive thrombosis of two major coronary vessels was observed at coronary angiography during evolving myocardial infarction. In all cases the simultaneous involvement of both vessels as the cause of acute ischemia was confirmed by the results of sequential treatment of the lesions with emergency angioplasty.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
10/59. Stenting with intravenous abciximab infusion for the treatment of left main coronary artery thrombosis during coronary angioplasty.A 67-year-old female patient complained of exertional precordial chest pain with radiation to the left shoulder occurring over a two-month period. An acute non-Q wave anterior myocardial infarction was diagnosed. On the third day of admission, coronary angiography revealed two-vessel disease with 73% luminal narrowing of the proximal left anterior descending coronary artery and 50% luminal narrowing of the mid-right coronary artery. The initial attempt to implant a NIR stent (boston Scientific/Scimed, Inc., Maple Grove, minnesota) was unsuccessful. We report on the successful rescue implantation of two MAC (Maximum Arterial re-Creation) stents (Advanced Medical Technologies, germany), in conjunction with the infusion of abciximab for the treatment of an abrupt closure due to thrombus of the left main coronary artery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
