1/207. Coronary stent deployment in a young adult with Kawasaki disease and recurrent myocardial infarction.A 19-year-old man developed a huge coronary aneurysm and stenosis in the right coronary artery as a sequela of Kawasaki disease (KD) that resulted in recurrent episodes of myocardial infarction. Coronary ischemic events were successfully prevented after balloon angioplasty followed by coronary stent implantation into the stenotic lesion. The stent deployment may have an advantage compared with balloon angioplasty and other new devices for the treatment for patients with KD showing stenotic lesions without dense calcification.- - - - - - - - - - ranking = 1keywords = infarction (Clic here for more details about this article) |
2/207. Coronary dissection and myocardial infarction following blunt chest trauma.myocardial infarction (MI) following blunt chest trauma is rarely diagnosed because the ensuing cardiac pain is commonly attributed to contused myocardium or the traumatic injuries in the local chest wall. There are only scattered reports on the coronary pathology associated with MI secondary to blunt chest trauma. Because differentiation of the pathology is difficult but important, we report here three cases of acute anterior MI secondary to coronary dissection following blunt chest trauma. Coronary dissection was demonstrated by coronary angiography. Two of the patients had intimal tears at the proximal left anterior descending artery (LAD) with normal flow, and the other patient had nearly total occlusion of the LAD associated with filling defects probably caused by an intracoronary thrombus. All three patients received conservative treatment without major complications and remained free from angina or heart failure throughout a 5-year follow-up period. In order to exclude associated MI in cases of blunt chest trauma, electrocardiography is necessary, and coronary angiography may be indicated to demonstrate coronary arterial pathology. dissection of the coronary artery with subsequent thrombus formation is one of the possible pathophysiologic mechanisms of MI following blunt chest trauma.- - - - - - - - - - ranking = 1keywords = infarction (Clic here for more details about this article) |
3/207. Spontaneous coronary artery dissection: favorable outcome illustrated by angiographic data.Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction. It typically occurs in young women receiving oral contraceptive therapy or during the peripartum period. In the case presented here, spontaneous complete healing at angiography and the favorable outcome may support the role of conservative treatment in such patients.- - - - - - - - - - ranking = 0.2keywords = infarction (Clic here for more details about this article) |
4/207. Multivessel spontaneous coronary artery dissection in a patient with severe systolic hypertension: a possible association. A case report.Spontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial ischemia and infarction. hypertension has not been associated with SCAD. The authors report multivessel SCAD in an elderly woman with severe systolic hypertension. They postulate that hypertension of this degree may play a pathophysiologic role in the causation of SCAD.- - - - - - - - - - ranking = 0.2keywords = infarction (Clic here for more details about this article) |
5/207. Occurrence of a saccular pseudoaneurysm formation two weeks after perforation of the left anterior descending coronary artery during balloon angioplasty in acute myocardial infarction.We describe the occurrence of a localized saccular pseudoaneurysm in a 69-year-old patient 2 weeks after perforation of the left anterior descending coronary artery during balloon angioplasty in acute myocardial infarction. The therapy of perforations requires prolonged balloon inflations, perfusion balloons, covered stents, or surgery. Coronary peudoaneurysm formations are rare; their therapy requires covered stents or surgery. Cathet. Cardiovasc.

6/207. Inadvertent stenting of left main coronary artery complicated by later in-stent restenosis.Stenting of both the protected and unprotected left main coronary artery has been described. This case presents a patient who had inadvertent left main stent deployment. A 47-year-old female presented with a non-Q-wave infarction and subsequent angina leading to angiography and angioplasty of her proximal ramus intermedius artery. Recurrent angina and ECG changes necessitated repeat coronary angiography and angioplasty on the same day with Wiktor stent deployment to treat a resultant dissection. Poststent deployment pictures revealed that the stent had been partially deployed in the left main coronary artery. Additional balloon dilatations were performed at the ostia of the left anterior descending and circumflex arteries through the stent. Three months later the patient presented with progressive angina and was discovered to have severe distal left main stenosis. In a case such as this, stent removal may be preferable to leaving an unnecessary stent within the left main coronary artery. Cathet. Cardiovasc.

7/207. Spontaneous multivessel coronary artery dissection: repeated presentation in a healthy postmenopausal woman.Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction which is infrequently diagnosed antemortem. Most previously reported cases were found in women of whom a significant proportion presented during pregnancy or the postpartum period. We describe the first antemortem case of spontaneous coronary artery dissection, unrelated to pregnancy or the postpartum state, which ultimately resulted in diffuse involvement of both the left and right coronary arteries over a period of 4 months. Pathophysiology and case management of this disorder are discussed.- - - - - - - - - - ranking = 0.2keywords = infarction (Clic here for more details about this article) |
8/207. Multiple coronary aneurysms in a case of systemic lupus erythematosus.A 29-year-old woman with active systemic lupus erythematosus (SLE) sustained an anterior myocardial infarction and demonstrated angiographic evidence of multiple, diffuse coronary aneurysms. Coronary artery aneurysms have been reported in 11 prior cases of patients with SLE. A medline search of the literature revealed no prior reports of extensive aneurysmal dilatations involving all three main coronary arteries (left anterior descending, left circumflex, and right coronary arteries).- - - - - - - - - - ranking = 0.2keywords = infarction (Clic here for more details about this article) |
9/207. Spontaneous dissection of coronary artery in a patient with ascending aortic aneurysm and aortic valve regurgitation.Spontaneous coronary artery dissection is a rare cause of myocardial infarction associated with a significant high morbidity and mortality. It usually occurs in relatively young patients and it is frequently found at autopsy. We report a case of a 42-year-old woman, who underwent resection of subaortic diaphragm ten years earlier presenting with postero-lateral myocardial infarction. Coronary arteriography revealed a dissection of the left main stem extending distally to the left anterior descending artery (LAD) and circumflex artery (Cx); occlusion of the postero-lateral branch of the Cx; severe aortic valve regurgitation and ascending aortic aneurysm. She was successfully operated on in emergency and underwent myocardial revascularization and separate replacement of the aortic valve and the ascending aorta. In this specific case of coronary dissection and severe aortic regurgitation it is mandatory to perform surgery in emergency to limit infarction evolution and avert loss of life.- - - - - - - - - - ranking = 0.6keywords = infarction (Clic here for more details about this article) |
10/207. Surgical management of arteriosclerotic coronary artery aneurysm.A 60-year-old man suffered antero-septal myocardial infarction at the age of 56. coronary angiography demonstrated total occlusion of the left anterior descending artery and a large saccular aneurysm of the right coronary artery. Diffuse coronary ectasia was also shown in the right coronary artery adjacent to the aneurysm. Despite anticoagulant therapy, the aneurysm formed a thrombus and developed coronary artery stenosis distal to the aneurysm. ligation of the aneurysm and in situ gastroepiploic artery grafting were performed. Sudden heart failure was developed during skin closure. As this condition was considered to be graft hypoperfusion, supplemental saphenous vein grafting was placed. ligation is a simple, reliable technique to prevent future complications for a large saccular right coronary artery aneurysm, however, gastroepiploic artery might be an inappropriate bypass conduit for the ligated coronary artery with diffuse ectasia.- - - - - - - - - - ranking = 0.2keywords = infarction (Clic here for more details about this article) |
