Cardiac intimal sarcoma is extremely rare and aggressive primary malignant cardiac tumors. Here, we reported the case of a young man initially operated for a tumor of the left atrium, causing a dynamic obstruction of the mitral valve and (mis‐)diagnosed as a myxoma at the histopathological analysis. Patient presented a local recurrence at 3 months and was reoperated. Pathology revealed this time the presence of an intimal sarcoma. Patient received adjuvant chemotherapy. Despite a good local control, the 1‐year follow‐up positron emission tomography scan revealed the presence of a metastasis in the left adrenal gland that was surgically resected. This article aims to highlight the risk of misdiagnosis in case of cardiac tumors, the hypothetical concept of malignant transformation of a cardiac myxoma, the aggressive course of the extremely rare cardiac intimal sarcoma, and the therapeutic modalities available to treat this pathology. 相似文献

This is a case report of a Fontan patient with previous Potts anastomosis who underwent stent implantation for left pulmonary artery stenosis. At follow-up the patient developed a fistula between the descending thoracic aorta and the left pulmonary artery at the site of the stent. This represents a late complication of stent placement. 相似文献

Background
Acquired complete heart block, in pediatric age is mainly the results of direct injury to conduction tissue during cardiac surgery or cardiac catheterisation. It can also be observed in different clinical settings as infectious diseases, neoplasia, and inflammatory diseases. It has a wide range of presentation and in some settings it can appear a dramatic event. Although a rare finding during acute rheumatic fever, with a transient course, it may need a specific and intensive treatment.Case presentation
We report the case of an Adams-Stokes attack in an adolescent with acute rheumatic carditis and complete atrio-ventricular block. The attack was the first symptom of carditis.We reviewed the literature and could find 25 cases of complete atrio-ventricular block due to rheumatic fever. Ten of the 25 patients experienced an Adams-Stokes attack. Nineteen of the 25 patients were certainly in the pediatric age group. Seven of the 19 pediatric cases experienced an Adams-Stokes attack. In 16/25 cases, the duration of the atrio-ventricular block was reported: it lasted from a few minutes to ten days. Pacemaker implantation was necessary in 7 cases.Conclusion
Rheumatic fever must be kept in mind in the diagnostic work-up of patients with acquired complete atrio-ventricular block, particularly when it occurs in pediatric patients. The insertion of a temporary pacemaker should be considered when complete atrio-ventricular block determines Adams-Stokes attacks. Complete heart block during acute rheumatic fever is rare and is usually transient. Along with endocarditis, myocarditis and pericarditis, complete atrio-ventricular block has been recognized, rarely, during the course of acute rheumatic carditis.5.

The antioxidant activities of 53 medicinal plants used in Bamun Folk Medicine for the management of jaundice and hepatitis were investigated. The studies were done using rat hepatic microsomes for lipid peroxidation and bovine serum albumin (BSA) for carbonyl group formation. Silymarine was used as reference compound. Fifteen different extracts were effective at a dose of 200µg/ml in both experiments. Specifically, 25 extracts inhibited lipid peroxidation initiated non-enzymatically by ascorbic acid while 18 inhibited peroxidation as determined by reduced Nicotinamide Adenine Dinucleotide Phosphate (NADPH). The inhibitory concentration 50 (IC50) of 23 different plant extracts was lower than 200µg/ml in the microsomal lipid peroxidation inhibition study. Fifteen of the 23 extracts were active in preventing protein oxidation by inhibiting the formation of the carbonyl group on BSA with an IC50 value less than 200µg/ ml. The results suggest that the antioxidant activity of the extracts, may be due to their ability to scavenge free radicals involved in microsomal lipid peroxidation or in protein oxidation. These biochemical processes are involved in the aetiology of toxic hepatitis. 相似文献

Transcatheter closure is the preferred method of treatment of patent ductus arteriosus (PDA). Detachable coils are widely used to close small ducts, while the Amplatzer duct occluder (ADO) is generally employed for moderate or large ducts. Recently a new device, the Amplatzer duct occluder II (ADO II), a nitinol flexible mesh, with a symmetrical design to provide high conformability for treatment of all types of PDA, has received the European Community mark approval. We report on one of the first experience, four cases (1 male, 3 female, age ranging from six months to seven years old) with different type and size of PDA treated with the new device. The use of this new Amplatzer duct occluder in our experience has the advantage of ease and safety of placement, conformability, stability, low profile catheters, adaptability for long ducts as in type E.

BACKGROUND: The Senning operation for transposition of the great arteries (TGA) was first introduced by Senning in 1959 and was revived by Quaegebeur et al. in the late 1970s, thus becoming the intervention of choice for the correction of TGA in many centers. HYPOTHESIS: The purpose of this study was to evaluate the long-term follow-up of a group of patients undergoing surgery with the Senning procedure for TGA. METHODS: From November 1978 to November 1987, 73 consecutive patients underwent the Senning operation. The 70 survivors had an average follow-up of 19 years (16-25 years). RESULTS: (1) Cardiac rhythm: with time there was a progressive decrease in stable sinus rhythm (60% after 20 years) and a progressive increase of supraventricular tachyarrhythmias requiring therapy (10% after 20 years). (2) Right ventricular function: 20% of the patients had reduced ejection fraction. (3) Late mortality: in the last 12 years of follow-up years there were two sudden deaths (2.8%). (4) Functional status: 80% of patients were in NYHA class I, 17% in class II, and 3% in class III. CONCLUSIONS: Our results confirm that the patients who undergo the Senning procedure have a progressive loss of sinus rhythm, an increase in active arrhythmias, and other important adverse outcomes such as late sudden death and a decrease in right ventricular function; however, most patients (93% in our series) are alive and in good functional status. 相似文献

The in vitro hepatoprotective effect of the methanolic extract from Ficus gnaphalocarpa (Miq.) Steud. ex A. Rich (Moraceae) on the CCl?-induced liver cell damage as well as the possible antioxidant mechanisms involved in this protective effect, were investigated. The phytochemical investigation of this methanolic extract led to the isolation of six compounds identified as: betulinic acid (1); 3-methoxyquercetin (2); catechin (3); epicatechin (4); quercetin (5); and quercitrin (6). The hepatoprotective activity of these compounds was tested in vitro against CCl?-induced damage in rat hepatoma cells. In addition, radical-scavenging activity, β-carotene-linoleic acid model system, ferric-reducing antioxidant parameter and microsomal lipid peroxidation assays were used to measure antioxidant activity of crude extract and isolated compounds. Silymarin and trolox were used as standard references and, respectively, exhibited significant hepatoprotective and antioxidant activities. (5), (6) and (2) showed significant antioxidant and hepatoprotective activities as indicated by their ability to prevent liver cell death and lactate dehydrogenase leakage during CCl? intoxication. These results suggest that the protective effects of crude extract of F. gnaphalocarpa against the CCl?-induced hepatotoxicity possibly involve the antioxidant effect of these compounds. 相似文献
