1/13. Treatment of saphenous vein graft thrombosis with distal protection, thrombectomy, and adenosine prior to reperfusion: a complete approach to preserving microvascular integrity.We report the treatment of an acute myocardial infarction presenting late with thrombotic total occlusion of a saphenous vein graft. A novel approach was used to prevent microvascular obstruction and reperfusion injury, with a distal protection system, a thrombectomy device, and administration of intracoronary adenosine prior to restoration of flow, so that initial reperfusion was done with maximal microvascular vasodilatation.- - - - - - - - - - ranking = 1keywords = reperfusion injury, reperfusion, injury (Clic here for more details about this article) |
2/13. Histopathological findings of the no-reflow phenomenon following coronary intervention for acute coronary syndrome.Although no-reflow phenomenon may occur in patients that experience reperfusion after ischemia, there have been no reports describing the postmortem findings in these patients. We describe the findings of an autopsy in a 56-year-old man who experienced acute coronary syndrome with no-reflow phenomenon after coronary intervention. Macroscopic study demonstrated myocardial infarction with diffuse hemorrhage, and microscopic analysis revealed vascular damage and microembolization in the no-reflow area. In conclusion, coronary microembolization and damage to the small coronary artery may contribute to the pathogenesis of no-reflow phenomenon following coronary intervention in humans.- - - - - - - - - - ranking = 0.011281108848988keywords = reperfusion (Clic here for more details about this article) |
3/13. Reperfusion-related polymorphic ventricular tachycardia as a possible mechanism of sudden death in patients with anomalous coronary arteries.We describe a patient with anomalous origin of the left coronary artery in whom polymorphic ventricular tachycardia developed immediately after an episode of chest pain with ST segment elevation. This is the first report providing direct evidence that reperfusion arrhythmias may be the cause of sudden death in individuals with anomalous coronary arteries.- - - - - - - - - - ranking = 0.011281108848988keywords = reperfusion (Clic here for more details about this article) |
4/13. Complete rupture of the posterior papillary muscle caused by late reperfusion for acute myocardial infarction.We describe a patient with acute mitral regurgitation due to complete rupture of the papillary muscle immediately after successful late reperfusion for inferior myocardial infarction. An 81-year-old woman was admitted complaining of mild chest discomfort. Although the electrocardiograms, biochemical test results, and her clinical history showed that several days had passed since the onset of acute myocardial infarction, a late coronary stenting was performed. Immediately after successful stenting, she suddenly developed acute pulmonary edema, leading to cardiogenic shock. In addition to high pulmonary capillary wedge pressure (mean 35 mmHg), color Doppler imaging revealed massive mitral regurgitation caused by complete rupture of the posterior papillary muscle. Emergent mitral valve replacement with a prosthetic valve was performed, saving the patient. Hence, late reperfusion should be considered carefully when treating a patient with a high risk, such as an elderly patient or a patient with single-vessel disease or initial transmural myocardial infarction.- - - - - - - - - - ranking = 0.067686653093925keywords = reperfusion (Clic here for more details about this article) |
5/13. Repeated 99mTc-Sestamibi studies for the evaluation of salvaged myocardium and of its relationship with postinfarction ischemia.Pre- and post-treatment myocardial scans with 99mTc-Sestamibi demonstrated effective reperfusion after thrombolysis in a patient with acute myocardial infarction. Late follow-up images showed at rest a further noteworthy reduction of the uptake defect and that during exercise a large part of the salvaged territory became ischemic. This report demonstrates that a remarkable amount of myocardium in the posttreatment images was hibernated; furthermore, it was possible to visualize directly that the salvaged territory is the actual site of exercise induced postinfarction ischemia.- - - - - - - - - - ranking = 0.011281108848988keywords = reperfusion (Clic here for more details about this article) |
6/13. Reperfusion and reperfusion injury in acute myocardial infarction.Recognition of the clinical markers of reperfusion and comprehension of the effects of reperfusion injury in acute myocardial infarction provide a unique challenge for today's critical care nurse. In this article we will explore the processes of reperfusion injury. A review of relevant literature and presentation of a clinical case study and care plan will enable the critical care nurse to construct a larger knowledge base and assist in the nursing management of patients with acute myocardial infarction. Evaluation and treatment of reperfusion and reperfusion injury remains under investigation, but through the skills of assessment, planning, and intervention the critical care nurse can coordinate prompt and appropriate care to the patient with an acute myocardial infarction.- - - - - - - - - - ranking = 6.6277234079834keywords = reperfusion injury, reperfusion, injury (Clic here for more details about this article) |
7/13. Acute myocardial infarction shortly after negative exercise test and reperfusion by intracoronary thrombolysis.A 67-year-old man developed an acute myocardial infarction shortly after normal exercise testing. His clinical history and findings from emergency coronary arteriography suggested that coronary artery spasm followed by intraluminal thrombosis might have been responsible for the myocardial infarction. Although intracoronary thrombolysis two hours after the onset of chest pain provided continued patency of an occluded vessel, serial myocardial perfusion scintigraphies documented myocardial injury, which was probably induced by reperfusion, rather than myocardial salvage.- - - - - - - - - - ranking = 0.056408114274799keywords = reperfusion, injury (Clic here for more details about this article) |
8/13. Termination of reperfusion arrhythmia by coronary artery occlusion.Reperfusion arrhythmias may be a cause of sudden death in acute myocardial infarction. A patient underwent successful coronary artery recanalisation by primary percutaneous transluminal coronary angioplasty (PTCA) for acute myocardial infarction. In this patient an idioventricular rhythm with a severe haemodynamic effect developed within one minute of deflation of the PTCA balloon. Sinus rhythm was immediately restored by reinflating the balloon and thus reinterrupting the supply of oxygenated blood. This suggests that reperfusion with consequent reoxygenation is a primary factor in arrhythmogenesis.- - - - - - - - - - ranking = 0.056405544244938keywords = reperfusion (Clic here for more details about this article) |
9/13. A patient in whom self-terminating ventricular fibrillation was a manifestation of myocardial reperfusion.Self-terminating ventricular fibrillation was recorded in a 47 year old woman without coronary artery or other structural heart disease. Reperfusion was thought to be responsible for the ventricular fibrillation because the arrhythmia started while the ST segment was returning to the baseline during an episode of silent ischaemia that was probably caused by coronary spasm. This case shows that potentially lethal arrhythmias can arise during reperfusion and that ventricular fibrillation during reperfusion may be self-terminating.- - - - - - - - - - ranking = 0.067686653093925keywords = reperfusion (Clic here for more details about this article) |
10/13. Preoperative antioxidant and allopurinol therapy for reducing reperfusion-induced injury in patients undergoing cardiothoracic surgery.Administration of vitamin e, vitamin C, and allopurinol to reduce reperfusion-induced injury remains controversial. Clinical trials are being conducted, and the results are promising. No adverse side effects have been reported with the short-term use of these drugs. The cost of the pre-operative medication is approximately $5 per week, which favors its use. The ability of nurses to be effective advocates of patients receiving these drugs is vital. What appears to be a trivial medication regimen may save myocardial cells and promote an uncomplicated postoperative period.- - - - - - - - - - ranking = 0.056418394394246keywords = reperfusion, injury (Clic here for more details about this article) |
