Coexistence of bicuspid aortic and pulmonary valves in the same patient is a very rare entity identified mainly during surgery and postmortem. To the best of our knowledge, only one case has been diagnosed by two‐dimensional echocardiography in a newborn with malposition of the great arteries but no images were presented. Here, we are reporting the first case of bicuspid pulmonary and aortic valves diagnosed by live/real time three‐dimensional transesophageal echocardiography in an adult with normally related great arteries. 相似文献

Eustachian valve (EV) is a vestige of the valve of the inferior vena cava which directs the umbilical vein blood through open foramen ovale in fetal life. Following birth it gradually regresses, but it may persist in variable size, shape, and thickness as a functionless and benign structure. However, there are reports suggesting that persistent EV may not be completely innocent. It has been accused of being a predisposing cause of patent foramen ovale and paradoxical embolism and also interfering with transseptal interventional procedures. It may serve as a site of infective vegetations and be mistaken as a tumor or thrombus. In the present case, an octopus‐like thrombus attached to the EV was delineated with the utility of two‐dimensional and real time three‐dimensional transesophageal echocardiography. EV was considered to play an essential role in preventing potential pulmonary embolism. 相似文献

We report an impressive case in which a complete infarction of the right hemisphere due to an acute occlusion of the right carotid artery had developed. After cerebral decompression and neurological rehabilitation, the persisting dissection of the ascending aorta and both carotid arteries was successfully repaired in one session. 相似文献

Acute onset abdominal pain constitutes a significant proportion of emergency department visits, but only a small fraction of these cases are attributable to vascular pathologies (Bauersfeld, 1947 [1]). In this case, report, we present an incidental diagnosis of Spontaneous Isolated Superior Mesenteric Artery Dissection (SISMAD). A 69-year-old man was admitted to the emergency department complaining of fever, loss of appetite, vague epigastric pain, dysuria, and a productive cough for several days. A lower extremity venous Doppler ultrasound was performed, and a deep venous thrombosis (DVT) was identified in the left main femoral vein and in the proximal segment of the superficial vein. The patient also had no blood flow in the distal part of left external iliac vein. A contrast-enhanced computerized tomography angiography of the thorax and abdomen was performed to detect pulmonary embolism and the etiology of the abdominal pain. No pulmonary embolism was found; however, multiple metastatic nodules were identified in both lungs, as well as infiltration on the posterobasal field of the right lung, metastases on the liver, focal dilatation, and an intimal flap on the middle-distal part of the superior mesenteric artery (SMA) at 2?cm, with a segment that was compatible with isolated dissection. There was a contrast passage on the distal part of SMA, and no sign of bowel ischemia. 相似文献

The predictive accuracy of electrocardiographic markers in identifying the infarct-related artery of myocardial infarctions has been a subject of extensive investigation. The present study was designed to test whether the index L II/L III ratio adapted to exercise electrocardiograms could be utilized as a marker to distinguish right coronary and left circumflex arteries as culprit coronaries in acute inferior myocardial infarctions. For this purpose, 82 patients with a positive-symptom-limited and/or submaximal treadmill exercise test with modified Bruce protocol after an acute inferior myocardial infarction were studied. Those patients with ST segment elevation during the stress test were included in the study. ST segment index was defined as the ratio of exercise-induced ST elevation amplitude in L II/L III. Patients were classified as having an index > 1 (n=24) and < 1 (n=58), and the findings were compared with the findings on coronary angiography. The groups were comparable with respect to age, gender, peak exercise level, and double products achieved. Circumflex artery was the infarct-related one in the majority (21/24; 88%) of patients with an index > 1, whereas most (51/58; 88%) patients with an index < 1 had the culprit lesion in their right coronary artery (p<0.001). The ratio of exercise-induced ST elevations in leads L II and L III has a significantly high ability to discriminate the infarct-related coronary artery in patients with uncomplicated inferior myocardial infarction. Considering the prognostic importance of the type of coronary involvement, this index could be a part of predischarge evaluation in this patient group. 相似文献

OBJECTIVE: To identify, characterize, and compare proteolysis peptide products generated by metalloprotease digests of human articular cartilage. METHODS: Human articular cartilage was digested by the addition of exogenous metalloproteases, including matrix metalloproteinases 2, 3, 8, 9, 12, and 13 and aggrecanases ADAMTS-4 and ADAMTS-5. Proteolyzed peptide products were identified by proteomics methods using mass spectrometry. RESULTS: Complete sequences of the peptides proteolyzed from human articular cartilage, including N- and C-termini and hydroxylated posttranslational modifications, were determined. A wide variety of peptides, originating from types I, II, and III collagen, biglycan, prolargin, fibromodulin, fibronectin, decorin, cartilage oligomeric matrix protein, cartilage intermediate-layer protein, megakaryocyte-stimulating factor, mimecan, aggrecan, and lumican, was analyzed following metalloprotease digestion. Release of peptides varied as a function of time, enzyme specificity, and abundance. Specific type II collagen peptide biomarkers, including those containing the three-quarter-length fragment cleavage site and those containing the domains for helical peptide of type II collagen and C-telopeptide of type II collagen, were observed after release by selected proteases. CONCLUSION: The use of intact cartilage instead of purified protein substrates in the assay allowed for the identification of novel potential substrates and cleavage sites for individual enzymes under more physiologically relevant conditions. Characterization of these cartilage matrix peptides may help in the development of pharmacodynamic biomarkers of cartilage degradation, and also may contribute to an understanding of the bioactive peptides important in chondrocyte signaling. 相似文献
