1/54. Single coronary artery with "high take-off" origin in a patient with rheumatic mitral stenosis--a case report.In this case report, a patient with rheumatic mitral stenosis and R-1 subtype single coronary artery arising from the ascending aorta ("high take-off" origin) and coursing between the aorta and pulmonary artery is presented. The clinical significance and differential diagnosis are discussed. To the authors' knowledge, this is the first case reported in the literature with a single R-1 subtype coronary artery that shows "high take-off" origin.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/54. Iatrogenic left main coronary artery stenosis.Iatrogenic left main coronary artery stenosis is a potentially life-threatening complication of cardiac valve replacement surgery due to injury by perfusion cannulas. This requires prompt clinical recognition and diagnosis by repeat coronary angiography, and treatment by early coronary artery bypass grafting. We present 3 patients who had normal coronary arteries prior to valve replacement surgery, and who developed severe left main coronary artery stenosis after surgery. Accelerating angina and refractory ventricular arrhythmia were presenting clinical manifestations. coronary artery bypass grafting was successfully performed in all 3 patients.- - - - - - - - - - ranking = 1.5keywords = coronary (Clic here for more details about this article) |
3/54. Regression of large atrial thrombi and coronary neovascularizations with conventional anticoagulation in mitral stenosis--a case report.The authors report a case of angiographically documented multiple coronary neovascularizations originating from the left circumflex artery (LCX) and coursing toward multiple thrombi located in the left atrium in a patient with severe mitral stenosis. The thrombi as well as the neovascularizations underwent near-complete resolution with 4 weeks' anticoagulation therapy with warfarin maintaining an international normalization ratio of 3.5. Percutaneous mitral balloon valvuloplasty was performed successfully without complications.- - - - - - - - - - ranking = 0.83333333333333keywords = coronary (Clic here for more details about this article) |
4/54. erythropoietin in Jehova's witness heart surgery.The patients, reported here, needed open heart surgery, but religion obliged them to refuse blood transfusion. Three of the four patients suffered from obstructive coronary diseases and one from mitral valvular disease, prevalently stenosis. All of them refused blood transfusions. One of the three patients presented, was refused by an other Cardiovascular Surgery Center because of his low blood values (Haemoglobin 9.2--Haematocrit 26.7). All these patients had been treated with subcutaneous injection of epoetin alfa 10,000 U twice a week and ferrous sulphate 525 mg three time a day per os, for three weeks before operation. Haemoglobin, haematocrit and reticulocytes values were controlled in pre, postoperative and at discharge. With this treatment the authors found haemoglobin and haematocrit values so increased to allow surgery without blood transfusion during and in the post operative period.- - - - - - - - - - ranking = 0.16666666666667keywords = coronary (Clic here for more details about this article) |
5/54. Mitral valve plasty in systemic lupus erythematosus in the setting of antiphospholipid syndrome.The first case was of a 27-year-old female, who was diagnosed as having mitral valve stenosis with regurgitation, systemic lupus erythematosus and antiphospholipid syndrome at her previous pregnancy. We performed mitral valve plasty, which included open mitral commissurotomy and Kay's annulo plasty. The second case was of a 53-year-old female, who was diagnosed as old myocardial infarction, mitral regurgitation, systemic lupus erythematosus and antiphospholipid syndrome. She underwent mitral valve plasty and coronary artery bypass grafting. Both cases were treated by administration of methylpredonisolone and heparin perioperatively to avoid thrombosis and aggravation of systemic lupus erythematosus. Both patients showed good postoperative outcome without complications. We consider that it is important to perform the plasty as far as possible, and to administer effective anticoagulation treatment to prevent complications for patients in the setting of systemic lupus erythematosus and antiphospholipid syndrome.- - - - - - - - - - ranking = 0.16666666666667keywords = coronary (Clic here for more details about this article) |
6/54. Current indications for left thoracotomy in coronary revascularization and valvular procedures.BACKGROUND: Left thoracotomy is infrequently used for cardiac procedures, but its application in reoperative and minimally invasive coronary revascularization and in valvular procedures has been reported recently. methods: Three case reports and a review of the current literature illustrate the unique benefits of this approach for myocardial revascularization and valve replacement. RESULTS: Reoperative coronary revascularization of the left anterior descending and circumflex coronary arteries was performed off-pump via a left posterolateral thoracotomy. For the second case, this approach was used for coronary artery bypass grafting of the right coronary and left anterior descending arteries with femoral-femoral cardiopulmonary bypass in a patient with congestive heart failure and coronary artery disease who also required closure of a patent ductus arteriosus. In the third case, mitral valve replacement using femoral venous and aortic cannulation for cardiopulmonary bypass was performed via a left thoracotomy to avoid a retrosternal gastric conduit in a patient with severe mitral stenosis and congestive heart failure. All patients returned to normal activity and are asymptomatic. CONCLUSIONS: These case reports and a comprehensive review of the literature demonstrate the utility of left thoracotomy as an alternative approach to standard median sternotomy in selected cases of revascularization and valvular procedures.- - - - - - - - - - ranking = 1.6666666666667keywords = coronary (Clic here for more details about this article) |
7/54. calcium embolism of the coronary arteries after percutaneous mitral balloon valvuloplasty.Two cases of rare, catastrophic calcium emboli to the coronary arteries immediately after percutaneous mitral balloon valvuloplasty are presented. Preoperative echocardiographic findings may identify patients at risk for this complication. These cases should increase the awareness of calcium emboli and lead to consideration of urgent coronary angiography for patients with signs or symptoms of acute coronary occlusion after valvuloplasty.- - - - - - - - - - ranking = 1.1666666666667keywords = coronary (Clic here for more details about this article) |
8/54. Anomalous coronary artery origin associated with bicuspid aortic valve in a patient with rheumatic mitral stenosis: a case report.A rare case of an anomalous left coronary artery arising from the right sinus of Valsalva associated with bicuspid aortic valve is presented. This case is unique because these congenital anomalies were associated with rheumatic mitral stenosis. This anomalous coronary origin was found at catheterization before balloon mitral valvuloplasty. The clinical significance of this finding is discussed.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
9/54. Coronary artery fistulae from single coronary artery in a patient with rheumatic mitral stenosis.Here we report coronary artery fistulae (CAF) arising from a single coronary artery in a patient with rheumatic mitral stenosis. A 62-year-old woman underwent a coronary angiogram prior to mitral valve replacement (MVR). The left coronary artery angiogram showed the right coronary artery arising from the left anterior descending coronary artery. From the distal left circumflex artery, two CAF were seen draining into left atrium. The haemodynamically insignificant fistulae were left alone and patient underwent MVR. Such an association has not been reported so far.- - - - - - - - - - ranking = 1.6666666666667keywords = coronary (Clic here for more details about this article) |
10/54. Thrombotic occlusion of the left main coronary artery during coronary angiography.A case of left main occlusion due to thrombus during coronary angiography is reported. This rare and extremely dangerous complication was successfully managed with resuscitation maneuvers, hemodynamic support, urgent balloon angioplasty plus stent implantation, anticoagulation with heparin and potent therapy directed at preventing platelet aggregation. The thrombus most likely detached from the arterial sheath, although coexisting circumstances, such as the use of non-ionic contrast or a transient hypercoagulable state, may have had an influence. A careful technique during the procedure is probably the most effective preventive measure.- - - - - - - - - - ranking = 1.5keywords = coronary (Clic here for more details about this article) |
