1/77. 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 = 1keywords = vessel (Clic here for more details about this article) |
2/77. Coronary arteriovenous fistulas with giant aneurysm: two case reports.Coronary arteriovenous fistulas are rare, particularly in association with coronary aneurysms. Two rare cases of patients with coronary arteriovenous fistulas and giant aneurysmal formation are described. A right coronary fistula that drained into the superior vena cava was demonstrated in one patient. The remaining patient had a documented left coronary fistula that drained into a main pulmonary artery and had evidence of several plexal vessels that transversed through the pulmonary trunk and toward the pericardial reflex. Under cardiopulmonary bypass, the fistulas and plexal vessels were successfully ligated without any injury to the native coronary circulation.- - - - - - - - - - ranking = 0.4keywords = vessel (Clic here for more details about this article) |
3/77. Coronary artery aneurysm after stent implantation.A coronary artery aneurysm that developed 6 months after coronary stent implantation in the left anterior descending artery, was treated by double coronary artery bypass grafting due to restenosis of the affected vessel and progression of right coronary artery stenosis. Although the poststenting aneurysm initially remained postoperative angiography showed that it had disappeared. In addition to thrombotic occlusion, another mechanism behind its disappearance may be that geometric changes of the implanted stent caused by heart retraction during surgery closed the entrance to the aneurysm.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
4/77. 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 = 0.2keywords = vessel (Clic here for more details about this article) |
5/77. Expanding subintimal coronary dissection under a stent-covered arterial segment: serial intravascular ultrasound observations.A patient with an angiographically unrecognized minor coronary dissection in a stent-covered coronary segment in which a type D spiral dissection extended submedially to the distal artery is described. This complication occurred 6 months after stent implantation and was ascribed to injury of the stented vessel wall during an intravascular ultrasound study.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
6/77. 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 = 0.8keywords = vessel (Clic here for more details about this article) |
7/77. Direct repair of giant right coronary aneurysm.We describe a novel method for surgical repair of giant right coronary aneurysm. Instead of aneurysm ligation and coronary bypass we mobilized the inflow and outflow and performed end-to-end anastomosis. This preserved the native vessel. Restudy in both patients confirmed the effectiveness of this technique.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
8/77. Combination of aneurysm and myocardial bridging at the same site of a coronary artery in a patient with obstructive hypertrophic cardiomyopathy.This case report describes the rare finding of myocardial bridging and a coronary aneurysm in the same coronary artery segment of a 57-year-old patient with obstructive hypertrophic cardiomyopathy. At the site of the aneurysm in the proximal LAD, the myocardial bridging resulted in an almost normal vessel diameter during systole with an aneurysmatic expansion of the vessel during diastole. This accidental finding does not necessarily require special therapy, since the underlying coronary aneurysm is small, with a low risk of thrombus formation or rupture, but it is big enough to prevent a coronary obstruction due to the myocardial bridging.- - - - - - - - - - ranking = 0.4keywords = vessel (Clic here for more details about this article) |
9/77. Multiple coronary artery aneurysms in a child with neurofibromatosis type 1.A number of frequently unrecognised vascular manifestations have been described in patients with neurofibromatosis type 1 (NF1), including involvement of the great vessels, cerebral, visceral and renal arteries. Rarely, changes in the coronary arteries have been reported in adults with NF1. We report on a 16-year-old boy affected by NF1 with dysmorphic features and three aneurysms in the mid-portion of the left descending coronary artery disclosed by chance during investigation for a malignant peripheral nerve sheath tumour. Molecular analysis detected a gross de novo deletion in the NF1 gene. The boy had had no previous cardiac symptoms but died suddenly after developing signs and symptoms suggestive of myocardial infarction. CONCLUSION: To the best of our knowledge, this represents the first report of multiple lesions in the coronary arteries in a child affected by neurofibromatosis type 1 with a known deletion of the neurofibromatosis type 1 gene.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
10/77. Coronary angiodysplasia of epicardial and intramural vessels.A case of coronary angiodysplasia combining large aneurysms of epicardial arteries with diffuse malformation of intramural vessels is reported. Clinical presentation may mimic a vascularized cardiac tumor. Although leaking of the aneurysms in the pericardial space may occur, this entity seems to have a benign prognosis not requiring surgical repair.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
