1/116. fibromuscular dysplasia involving coronary arteries--a case report.The authors report a young patient with fibromuscular dysplasia involving multivessels including coronary arteries. If young patients have chest pain on effort, fibromuscular dysplasia of coronary arteries must be considered. As fibromuscular dysplasia is a chronic progressive disease and some cases progress rapidly in a few months, careful follow-up and comprehensive medical management may be necessary in such patients.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/116. Long-term successful coronary artery angioplasty in polycythemia vera.In a 65-year-old man with polycythemia vera, invalidating angina pectoris was associated with severe narrowing of the right coronary artery. After percutaneous coronary angioplasty (PTCA) the patient became symptom free and remained so for 12 months, while receiving an antiplatelet agent, a calcium antagonist and nitrate. coronary angiography repeated after a year, because of reappearance of angina, documented good patency of the treated artery and some progression of a narrowing involving another coronary vessel. This is the first reported case of long-term success of PTCA in polycythemia vera, a disease exposed to a high risk of thrombosis and, possibly, of restenosis. It is undefined whether medical treatment contributed to the anatomical and clinical results. As far as a single case can say, polycythemia vera might not represent a prohibitive background for coronary PTCA.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/116. 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 = 5keywords = vessel (Clic here for more details about this article) |
4/116. Anesthetic management of high-risk cardiac patients undergoing noncardiac surgery under the support of intraaortic balloon pump.patients with severely impaired left ventricular function, an uncorrectable coronary artery disease, and a recent myocardial infarction are at high risk of cardiac complications after major noncardiac surgery. We present two patients with extensive three-vessel coronary artery disease who underwent intraperitoneal surgery under the support of intraaortic balloon pump (IABP). In one patient, the IABP was inserted urgently because of the development of chest pain with significant ST depression on arrival in the operating room, and the other patient was managed with prophylactic IABP. There were no intraoperative or postoperative cardiac events in either patient. Thus, IABP should be considered in the perioperative management of patients with severe cardiac diseases.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/116. Anomalous origin of the right coronary artery from the left anterior descending coronary artery: a case report.We report on a 59-year-old man with effort angina of recent onset and a very uncommon right coronary artery originating from the middle portion of the left anterior descending; a tight stenosis of the left anterior descending coronary artery was also detected which involved the origin of the aberrant vessel.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/116. 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) |
7/116. Doppler features of occlusion of the internal thoracic artery due to preoperative branch embolization.A 61-year-old male was referred to the surgical ward by cardiologists because of a diagnosis of unstable angina with 3-vessel disease. On preoperative left internal thoracic arteriography, a large first intercostal branch was found at the proximal portion. Selective arterial embolization of the branch of the left internal thoracic artery (LITA) was carried out preoperatively. At 2 days after embolization, the Doppler peak flow velocity and diameter of the LITA were increased and enlarged compared with before the procedure. However, a large reverse wave following after the first systolic peak flow of the LITA was newly detected after embolization. Upon operation, the LITA was found to be occluded at the 2nd intercostal space due to thrombus formation. Therefore, the right internal thoracic artery was anastomosed to the left anterior descending artery and coronary reversed saphenous vein grafts were joined to segment 4PD of the right coronary artery. The postoperative course was uneventful. There has been no previous report of an LITA branch being embolized preoperatively. It was possible to diagnose the graft problem by detecting the altered Doppler wave form of the LITA.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/116. Right ventricular infarction complicating coronary artery bypass grafting.Intraoperative right ventricular infarction immediately after coronary artery bypass grafting is a rare and potentially serious complication. We report a case in which an additional coronary artery bypass graft to a right ventricular branch with 99% stenosis brought about recovery from profound acute right ventricular failure. This case shows that complete revascularization to all graftable vessels, including even the right ventricular branch, is mandatory for successful coronary artery bypass grafting.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/116. Electrical neuromodulation for disabling angina pectoris related to isolated stenoses of small epicardial coronary arteries.patients with symptomatic small vessel coronary artery disease may be inadequate candidates for revascularization procedures. They may suffer from refractory angina, which does not respond to maximal anti-anginal drug therapy. In addition to patients with end stage coronary artery disease and syndrome X, this newly defined group of subjects with an isolated stenosis of a small coronary artery may benefit from electrical neurostimulation. We describe two patients with intractable angina caused by a significant narrowing of a diagonal branch. This treatment modality should be considered as an alternative method for unsatisfactory revascularization procedures.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/116. Off-pump CABG for a patient with a brain tumor.coronary artery bypass grafting (CABG) without cardiopulmonary bypass (off-pump CABG) was performed on a patient with a brain tumor. A patient with effort angina of the left anterior descending artery (LAD), and diagonal branch stenosis was referred to us for CABG. He had a mass lesion in the brain that was diagnosed as meningioma involving the internal carotid artery and a middle cerebral artery. To avoid brain complications, we performed off-pump CABG using the internal thoracic and radial arteries to the LAD and a diagonal branch. Off-pump CABG was an effective method to avoid brain complications for patients with a brain tumor involving cerebral vessels.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
