1/59. Intravascular ultrasound evaluation of a pseudolesion created by stent placement in the right artery.The creation of a pseudolesion after guidewire placement in tortuous arterial segments is a well recognized phenomenon. Intravascular ultrasound has been useful in assessing deployment of intracoronary stents and equivocal angiographic findings. We present a case in which a pseudolesion was not observed until after placement of an intracoronary stent. Intravascular ultrasound demonstrated no dissection or significant lesion; however, there was focal calcification just distal to the stent providing a substrate for the distorted vessel architecture. The lesion resolved with removal of the guidewire.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/59. Late stent malapposition occurring after intracoronary beta-irradiation detected by intravascular ultrasound.We report a case of late stent malapposition occurring 6 months after intracoronary beta-irradiation detected by three-dimensional intravascular ultrasound, in spite of good apposition immediately after the procedure. Volumetric quantification revealed that stent volume remained unchanged, whereas total vessel volume increased by 13% after 6 months within the stent area. The increase of the vessel volume took place mainly in the proximal part of the stent, where the malapposition was located.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
3/59. 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) |
4/59. Stenting of an anomalous left circumflex coronary artery arising from the right coronary artery.Coronary angioplasty can provide excellent means of revascularization of anomalous coronary arteries. Successful application of angioplasty to these vessels requires angiographic knowledge of their course, structure and appropriate equipment selection. Advancement of stent delivery systems in such cases requires good support with the possibility of selective cannulation and deep engagement of the guiding catheter. We report a case of stent placement in an anomalous circumflex artery arising from the right coronary artery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/59. Successful long-term therapy following saphenous vein-covered stent deployment for atherosclerotic coronary aneurysm.We describe a case of atherosclerotic aneurysm involving the left main coronary artery in a patient with prior coronary artery bypass surgery. A saphenous vein-covered stent was used to seal the aneurysm in conjunction with conventional stenting of an associated native vessel coronary stenosis. Focal late restenosis involving the stent graft was successfully treated with repeat angioplasty and brachytherapy. Autologous vein-covered stent deployment should be considered in the treatment of symptomatic or progressively enlarging coronary aneurysms.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/59. takayasu arteritis with multiple cardiovascular complications.A 60-year-old Japanese woman first presented in 1990 with effort angina. She underwent coronary angiography and was diagnosed with bilateral coronary ostial stenosis and takayasu arteritis. coronary artery bypass graft surgery (CABG) for multiple vessels was attempted, but the blood flow in the bilateral internal thoracic and gastroepiploic arteries was to poor for a donor artery, and the calcification of the ascending aortic wall was too severe for anastomosis of saphenous vein grafts. Therefore, the proper hepatic artery was connected to the left anterior descending artery using a vein graft. In April 2000, the patient's angina worsened. Occlusions of both subclavian arteries, bilateral coronary ostial stenosis and vein graft occlusion, aortic valve regurgitation, and two severe stenoses of the descending aorta were observed. aortic valve replacement, and coronary and aorta revascularization were desirable, but the severe aortic wall calcification and thickening rendered these interventions impossible. Treatment with medication was chosen. The patient was discharged without severe angina. A combination of these serious cardiovascular complications which do not allow any surgical intervention is very rare.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/59. Cutting balloon angioplasty through stent struts of a jailed sidebranch ostial lesion.The treatment of sidebranch ostial lesions jailed after stent implantation is challenging. We report a case of successful Cutting Balloon angioplasty through stent struts of a severe, elastic sidebranch ostial lesion. Three-day follow-up angiography showed no recurrent stenosis. The patient was discharged with complete resolution of chest discomfort and the post-hospitalization course was uneventful. Cutting Balloon angioplasty may be an optimal strategy for the treatment of elastic ostial lesions in smaller vessels that are suboptimal for stenting. The long-term benefits of using a Cutting Balloon for the treatment of sidebranch ostial lesions are still to be determined.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/59. Intravascular ultrasound catheter entrapment after coronary artery stenting.Intracoronary ultrasound (IVUS) facilitates optimal stent deployment in the treatment of coronary artery disease, which may favorably improve long-term outcome after stenting. Complications associated with IVUS include coronary vasospasm and rarely more serious adverse events such as vessel perforation or stent deformation. We report an IVUS catheter tip entrapment within a self-deploying nitinol stent.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/59. Acute myocardial infarction and Friedreich's ataxia.While cardiac disease is noted in 90% of patients with Friedreich's ataxia (FRDA), the finding of coronary artery disease is unusual. To the best of our knowledge only two cases of acute myocardial infarction (AMI) has been reported in patients with FRDA. Large vessel CAD has not been reported previously in patients with FRDA. We report a young patient with AMI and obstruction of large epicardial arteries.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/59. Acute stent recoil in the left main coronary artery treated with additional stenting.We report a case of acute stent recoil occurring after the stenting of an ostial left main coronary artery lesion. The marked recoil after high-pressure balloon inflation confirmed that the radial force of the first stent was unable to ensure vessel patency. The addition of a second stent provided the necessary support to achieve a good final result. This case illustrates a possible complication of aorto-ostial angioplasty that could be treated with double stenting.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
