1/93. Anaesthetic considerations in a patient with lepromatous leprosy.PURPOSE: To consider the anaesthetic problems in a patient with lepromatous leprosy undergoing general anaesthesia. CLINICAL FEATURES: A 52 yr old man with lepromatous leprosy for five years was booked for elective radical nephrectomy. He received 100 mg dapsone per day po. The patient was asymptomatic for cardiovascular disease but his electrocardiogram showed complete left bundle branch block, inferior wall ischaemia with echocardiogram findings of 58% ejection fraction and left ventricular diastolic dysfunction. Other preoperative investigations (haemogram, serum urea and creatinine, liver function tests and chest X-ray) were normal. After premedication with diazepam, meperidine and promethazine, the patient received glycopyrrolate and anaesthesia was induced with thiopentone. atracurium was given to facilitate tracheal intubation. Anaesthesia was maintained with intermittent positive pressure ventilation using N2O in oxygen with halothane. Anaesthesia and surgery were uneventful except that the patient had a fixed heart rate that remained unchanged in response to administration of anticholinergic, laryngoscopy, intubation and extubation. CONCLUSION: patients with lepromatous leprosy may have cardiovascular dysautonomia even when they are asymptomatic for cardiovascular disease.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/93. A case of eosinophilic myocarditis complicated by Kimura's disease (eosinophilic hyperplastic lymphogranuloma) and erythroderma.This report describes a patient with eosinophilic myocarditis complicated by Kimura's disease (eosinophilic hyperplastic lymphogranuloma) and erythroderma. A 50-year-old man presented with a complaint of precordial pain. However, the only abnormal finding on examinatioin was eosinophilia (1617 eosinophils/microl). Three years later, the patient developed chronic eczema, and was diagnosed with erythroderma posteczematosa. One year later, a tumor was detected in the right auricule, and a diagnosis of Kimura's disease was made, based on the biopsy findings. The patient developed progressive dyspnea 6 months later and was found to have cardiomegaly and a depressed left ventricular ejection fraction (17%). A diagnosis of eosinophilic myocarditis was made based on the results of a right ventricular endomyocardial biopsy. The eosinophilic myocarditis and erythrodrema were treated with steroids with improvement of both the eosinophilia and left ventricular function.- - - - - - - - - - ranking = 0.079838154918035keywords = pain (Clic here for more details about this article) |
3/93. Transient left ventricular failure following bilateral lung transplantation for pulmonary hypertension.BACKGROUND: Bilateral lung transplantation is an established therapy for end-stage pulmonary hypertension. Its early postoperative outcome may be biased by various complications resulting in unexpected deterioration of the patient in terms of hemodynamics and blood gases. methods: We have reviewed the early postoperative course of patients who underwent bilateral lung transplantation for pulmonary hypertension at our institution and analyzed all available data, especially hemodynamic measurements, echocardiographic documentation and therapeutical strategies, in those cases where cardiac dysfunction was found to be responsible for clinical deterioration. RESULTS: Three out of 20 lung transplant recipients operated for pulmonary hypertension experienced severe respiratory insufficiency accompanied by hemodynamic decompensation during the first days after surgery. Clinical and laboratory findings together with results of echocardiography and pulmonary artery catheterism helped establish the diagnosis of left ventricular failure. This proved to be transitory, but the response to therapy (inotropic drugs, afterload reduction and eventually prostaglandins) was very variable. Adequately treated, this complication did not preclude the outcome of transplantation by itself. CONCLUSION: Left ventricular failure is a possible complication after lung transplantation for pulmonary hypertension. echocardiography and pulmonary artery catheterism may be useful adjuvant diagnostic tools, beside routine physical examination, chest X-ray, and laboratory analysis. Therapy of this complication must be adapted individually and may be complex.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
4/93. Acute left ventricular dysfunction and subarachnoid hemorrhage.OBJECTIVE: Severe left ventricular (LV) dysfunction associated with acute subarachnoid hemorrhage (SAH) due to cerebral aneurysm rupture. SETTING: An adult 12-bed surgical intensive care unit of a university hospital. PATIENT: A female patient presenting with SAH (Hunt & Hess grade III) and severe left ventricular dysfunction. INTERVENTIONS: central venous pressure, arterial blood pressure, extravascular lung water catheter, transesophageal echocardiography, blood gas analysis, electrocardiograms, and chest x-ray for clinical management. MEASUREMENTS AND MAIN RESULTS: On admission to the district hospital, an electrocardiogram (ECG) revealed a sinus rhythm with transient ST elevations. A transesophageal echocardiography showed a left ventricular ejection fraction (LV-EF) of approximately 10%. Severe LV dysfunction required inotropic and vasopressor support to maintain mean arterial pressure above 60 mmHg, while the first measurement of an extravascular lung water catheter revealed a cardiac index of 2.0 L/min/m2 and moderate hypovolemia. Despite stepwise volume loading that increased intrathoracic blood volume--an indicator of cardiac preload--from 719 mL/m2 to 927 mL/m2, cardiac index remained poor. enoximone lead to a marked increase of cardiac index up to 3.9 L/min/m2 and LV-EF to about 30%, but had to be stopped due to thrombopenia. Surgical clipping of an intracranial aneurysm was postponed because of the impaired cardiac function and was performed on day 18 after admission. Interestingly, neurologic outcome was not as poor as might be expected from the literature. CONCLUSION: Severe left ventricular dysfunction may occur in acute SAH and may necessitate delay of aneurysm surgery.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
5/93. 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 = 37.247259650655keywords = chest pain, chest, pain (Clic here for more details about this article) |
6/93. The hibernating heart: reversible left ventricular dysfunction in chronic heart failure.A patient with severe heart failure secondary to coronary heart disease is presented. Following investigation he was thought to have significant areas of myocardial hibernation and was therefore treated with coronary revascularisation, with major clinical benefit.- - - - - - - - - - ranking = 0.012375359682037keywords = area (Clic here for more details about this article) |
7/93. pulmonary edema after cardioversion for paroxysmal atrial flutter: left ventricular diastolic dysfunction induced by direct current shock.This report describes a patient with the pulmonary edema after cardioversion for paroxysmal atrial flutter without organic heart disease. A 68-year-old man was admitted to hospital for paroxysmal atrial flutter. Antiarrhythmic agents were not effective, and direct current cardioversion was performed on the 4th hospital day. Three hours after cardioversion, the patient complained of dyspnea, and a chest X-ray showed pulmonary edema. He responded to oxygen, intravenous furosemide and drip infusion of nitroglycerine. During tapering of the medication, his condition remained stable. The patient was discharged on the 7th day after admission. Echocardiographic findings indicated that transient left ventricular diastolic dysfunction due to direct current shock was the most likely cause of the lung edema.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
8/93. Transformation of mitral valve prolapse to dynamic left ventricular outflow tract obstruction and back again in a patient with acute transient myocardial depression.We describe an unusual case of transient resolution of preexisting mitral valve (MV) prolapse during acute cardiac dysfunction and the development of dynamic left ventricular (LV) outflow tract obstruction. The patient presented with lightheadedness, chest pain, and compromised hemodynamic status. echocardiography revealed akinesis and deformation of the LV anterior wall and apex, hyperdynamic activity in the bases, anterior MV leaflet systolic anterior motion without prolapse, and a dynamic outflow tract gradient. Myocardial function fully recovered over 1 month. Repeat ultrasonography showed posterior MV leaflet prolapse and no anterior MV leaflet systolic anterior motion. Elongated MV leaflets may have contributed to dynamic outflow tract obstruction and life-threatening hemodynamic compromise during LV conformational change.- - - - - - - - - - ranking = 37.247259650655keywords = chest pain, chest, pain (Clic here for more details about this article) |
9/93. Dilated cardiomyopathy as the first early complication in a 14 year-old girl with diabetes mellitus type 1.Diabetic cardiomyopathy (DC) has been reported in type 2 diabetics with short duration of clinically overt diabetes. Impaired left ventricular function has been reported in young patients with diabetes mellitus type 1 (IDDM), but severe cardiomyopathy as the first early major complication of IDDM is very rare. We report a 14 year-old girl with a 5-year history of IDDM and very poor compliance with treatment and follow-up. She was referred to our clinic upon the development of congestive heart failure and dilated cardiomyopathy was diagnosed based on clinical findings, electrocardiogram, chest X-ray and echocardiography. She had no evidence of other major complications of IDDM such as retinopathy, nephropathy or neuropathy.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
10/93. 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 = 0.079838154918035keywords = pain (Clic here for more details about this article) |
