1/315. 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 = artery (Clic here for more details about this article) |
2/315. Coronary-subclavian steal associated with severe aortic stenosis treated with combined percutaneous stenting and minimally invasive aortic valve replacement.We describe coronary-subclavian steal restricting flow to the left internal mammary artery (LIMA) associated with critical aortic stenosis treated with combined percutaneous transluminal stenting and minimally invasive aortic valve replacement (AVR). An 86-year-old patient had coronary artery bypass graft placement (CABG) seven years prior with the LIMA anastomosed to the left anterior descending coronary artery (LAD). At the time of CABG, the patient had mild aortic stenosis and normal left ventricular function. By the time of re-presentation with refractory angina and heart failure, the patient had developed critical aortic stenosis. Because repeat CABG with median sternotomy risked damaging the LIMA, pre-operative revascularization was planned to minimize the likelihood of peri-operative ischemia. Stenting of the subclavian artery was performed prior to minimally invasive AVR.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
3/315. Primary and elective stenting of unprotected isolated left main coronary ostial stenosis in acute coronary syndrome.Direct surgical angioplasty or coronary artery bypass graft has been done in patients who have left main coronary ostial stenosis. Recent reports have demonstrated that stenting of unprotected left main coronary artery stenosis has been attempted as an alternative to bypass surgery in selected patients with normal LV function. We report two patients with isolated left main coronary ostial stenosis who are undergoing primary and elective stenting, respectively. Major cardiac events did not occur during a 3-month follow-up. This study suggests that stenting of isolated left main coronary ostial stenosis in acute coronary syndrome is feasible and results in excellent outcomes.- - - - - - - - - - ranking = 0.5keywords = artery (Clic here for more details about this article) |
4/315. Stenting of the right internal mammary artery graft and right coronary artery via a femoral approach.We describe a case of balloon angioplasty and stenting of the right internal mammary artery (RIMA) graft anastomosis and the native right coronary artery through an in situ RIMA graft using two Bard XT stents (USCI Division of C.R. Bard, Inc., Billerica, massachusetts). This case illustrates the feasibility of transluminal angioplasty and stenting of RIMA grafts and the native coronary artery using a femoral artery approach.- - - - - - - - - - ranking = 3keywords = artery (Clic here for more details about this article) |
5/315. 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 = 2.7776648494948keywords = artery disease, artery (Clic here for more details about this article) |
6/315. Second generation bifurcation stent: the rapid development of device technology.A 57-year-old male with unstable angina and an eccentric 88% diameter stenosis of the left anterior descending artery prior to, and involving the first diagonal branch was treated with the 2nd generation Jomed Sidebranch stent (Jomed, Randingengen, germany). This case outlines the improvements in this novel stent design and demonstrates the rapid advance of device design.- - - - - - - - - - ranking = 0.25keywords = artery (Clic here for more details about this article) |
7/315. 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 = 2.5keywords = artery (Clic here for more details about this article) |
8/315. angioplasty/bypass combination therapy in an 89-year-old man with left main trunk disease.We report a case of an 89-year-old man presenting with unstable angina and left main trunk disease. Minimally invasive direct coronary artery bypass grafting supplemented by catheter intervention was successfully performed. In view of the increasing elderly population, angioplasty/bypass combination therapy may be an important alternative for elderly coronary artery disease patients.- - - - - - - - - - ranking = 1.5138324247474keywords = artery disease, artery (Clic here for more details about this article) |
9/315. Stenting of the septal perforator coronary artery.This report describes the first application of intracoronary stenting to the septal perforator coronary artery in a patient with a totally occluded left anterior descending coronary artery (LAD) and a patent venous graft to the distal LAD. The procedure was successful and resulted in almost complete relief of class III angina. Therefore, diseased large septal perforators may cause angina and be treated effectively by intracoronary stenting in selected cases.- - - - - - - - - - ranking = 1.5keywords = artery (Clic here for more details about this article) |
10/315. Stenting to reverse left ventricular ischemia due to left main coronary artery compression in primary pulmonary hypertension.Angina is a common symptom of severe pulmonary hypertension. Although many theories for the source of this pain have been proposed, right ventricular ischemia is the one most commonly accepted as the cause. We report on two patients with primary pulmonary hypertension who had angina with normal activity or on provocation. One patient had severe left ventricular dysfunction. Both were found to have severe ostial stenosis of the left main coronary artery as a result of compression from a dilated pulmonary artery. Both patients underwent stenting of the left main coronary artery with excellent angiographic results, and complete resolution of the signs and symptoms of angina and left ventricular ischemia. Left ventricular ischemia due to compression of the left main coronary artery may be a much more common mechanism of angina and left ventricular dysfunction in patients with pulmonary hypertension than previously acknowledged. Stenting of the coronary artery can be done safely with the resolution of these symptoms.- - - - - - - - - - ranking = 2.25keywords = artery (Clic here for more details about this article) |
