1/45. Treatment of a large congenital coronary fistula with coil embolization.A 77-year-old woman suffering from progressive dyspnea and chest pain for 2 1/2 years was admitted to hospital. There were no ECG changes at exercise test and a dobutamine stress echocardiography was normal. At catheterization, right-sided pressures were within normal limits. coronary angiography revealed a congenital coronary fistula, 3-4 mm in diameter, from the left anterior descending artery to the proximal pulmonary artery. There was no significant rise in blood oxygen saturation in the pulmonary artery. Transcatheter coil embolization was performed in the distal part of the tortuous fistula. Flow ceased within minutes, demonstrating the feasibility and efficacy of this technique for treating large fistulas.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/45. Syphilitic aortic regurgitation. An appraisal of surgical treatment.During the 10 years from 1964 to 1973, fifteen patients with severe syphilitic aortic regurgitation were treated surgically at the National Heart Hospital. In thirteen the valve was replaced and in two it was repaired. In addition four had replacement of an aneurysmal ascending aorta with a Dacron graft and seven some form of plastic repair to the coronary ostia. Three patients died within 1 month of surgery and a further six during the follow-up period which varied from 1 to 55 months (mean 25-5). The six survivors have been followed-up for an average of 33 months. Factors contributing to this high mortality were analysed and it was found that the mean duration of effort dyspnoea was 22 months in the survivors compared with 48 months in those who had died. Similarly the average duration of nocturnal dyspnoea was 4 months in the survivors compared with a mean of 8 months in those who had died. Only six out of the fifteen patients had angina; this was present in two of the survivors and in four of the fatalities. The pulse pressure, heart size, and haemodynamic findings were similar in the two groups. The prognostic value of an elevated erythocyte sedimentation rate was also examined. It was concluded that preoperative investigations should include aortography, coronary arteriography, an assessment of left ventricular function, and whenever possible myocardial biopsy. These data were interpreted as suggesting that patients should be referred for surgery at an earlier stage in the disease--certainly before the onset of cardiac failure and--and that if this more aggresive attitude was adopted, as it has been in non-syphilitic cases of aortic valve disease, the present high mortality in this group would be reduced.- - - - - - - - - - ranking = 0.4keywords = coronary (Clic here for more details about this article) |
3/45. myocardial infarction with moyamoya disease and pituitary gigantism in a young female patient.myocardial infarction is very rare in young female patients with systemic vascular disorders. moyamoya disease is a cerebrovascular disease associated with an abnormal vascular network. This report presents a 19-year-old female patient who suffered from chest pain and exertional dyspnea for 2 months prior to admission. She had a history of moyamoya disease and pituitary gigantism since childhood. Her ejection fraction on echocardiogram was 20% and a perfusion defect with partial reversibility in the anterior wall was demonstrated on stress single photon emission computed tomography (SPECT). Diagnostic coronary angiogram revealed critical stenosis in the middle left anterior descending artery, which was treated by coronary stenting. Her subjective symptoms were relieved and the perfusion defect seen on SPECT decreased after coronary intervention.- - - - - - - - - - ranking = 0.6keywords = coronary (Clic here for more details about this article) |
4/45. Primary myxoid sarcoma of the pleura: 5 years follow-up.Primary sarcomas of the pleura are rare intrathoracic tumours. We describe a case of a recurring myxoid pleural sarcoma in a 51-year-old male patient with coronary heart disease, who initially was admitted for coronary revascularization surgery. Tumour diagnosis was based on pathological examination of a biopsy after radiological detection of a nodule in the right upper lobe. The nodule was excised. The first recurrence was diagnosed after 15 months. Pleuropneumonectomy was done. Four years after the first excision further tumour masses appeared above the diaphragm and were surgically removed and adjuvant irradiation carried out. A year later the patient is doing well.- - - - - - - - - - ranking = 0.4keywords = coronary (Clic here for more details about this article) |
5/45. Acute congestive heart failure associated with a limited form of systemic sclerosis and primary biliary cirrhosis.This is the first case of a limited form of systemic sclerosis (ISSc) associated with acute congestive heart failure (CHF) and primary biliary cirrhosis (PBC). A 58-year-old woman with ISSc was admitted because of a sudden onset of CHF. The intravenous administration of nitroglycerine and furosemide ameliorated the symptoms of CHF within 24 hours. She had both anticentromere antibodies and anti-p25 doublet/triplet antibodies to intrahepatic microsomes. thallium scintigraphy at rest demonstrated significant perfusion defects in both the anteroseptal and inferior myocardium. A coronary angiogram revealed normal coronary arteries and no vasospasm was provoked by the intracoronary administration of acetylcholine. The present case indicates that minute care should thus be taken for the prevention of acute CHF even in patients with a limited form of SSc when thallium perfusion defects are identified.- - - - - - - - - - ranking = 0.6keywords = coronary (Clic here for more details about this article) |
6/45. Aberrant right subclavian artery (arteria lusoria) as a rare cause of dysphagia and dyspnea in a 79-year old women with right mediastinal and retrotracheal mass, and co-existing coronary artery disease.A rare case of a 79-year old women with dysphagia and dyspnea secondary to compression of the esophagus by an aberrant right subclavian artery (ARSA, A. lusoria) is presented. This abnormality is generally silent and often an incidental x-ray finding. Computed tomography and intraarterial angiography, including direct catheterization of the ARSA, established the diagnosis. The interdependence with a co-existing coronary artery disease is discussed. Thus, ARSA has to be taken into account in patients with abnormal x-ray findings presenting with dysphagia and dyspnea.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
7/45. Successful treatment of endogenous lipoid pneumonia due to Niemann-Pick Type B disease with whole-lung lavage.In Type B Niemann-Pick disease, progressive pulmonary infiltration is a major cause of morbidity and mortality, although the disease is usually diagnosed before adulthood in other organ systems. To date, no successful treatment of pulmonary involvement by Niemann-Pick disease has been documented. We describe the case of a patient with Niemann-Pick Type B disease who presented with extensive endogenous lipoid pneumonia and life-threatening hypoxia following bypass grafting for severe coronary artery disease. A surgical lung biopsy at the time of grafting revealed characteristic histology and ultrastructural features of Niemann-Pick disease, with confirmatory findings in biochemical studies. Because of the severity of the patient's symptoms, bilateral whole-lung lavage was undertaken, leading to symptomatic improvement, lessening of parenchymal opacification on high-resolution computed tomographic scanning, and a marked improvement in resting arterial oxygen tension while breathing air to 10.3 kPa from 8.4 kPa. Whole-lung lavage may be a potentially useful modality of treatment for patients with pulmonary involvement by Niemann-Pick Type B disease.- - - - - - - - - - ranking = 0.2keywords = coronary (Clic here for more details about this article) |
8/45. Reversible left ventricular dysfunction "takotsubo" cardiomyopathy associated with pneumothorax.An 83 year old woman presented to the emergency department with chest pain and dyspnoea. Chest radiography showed pneumothorax of the left lung. arteries were normal on coronary angiography. Left ventriculography showed asynergy of apical akinesis and basal hyperkinesis. Within 18 days, the asynergy improved without any specific treatment. In the present case the left ventricular dysfunction may have been induced by altered catecholamine dynamics as a result of pneumothorax.- - - - - - - - - - ranking = 0.2keywords = coronary (Clic here for more details about this article) |
9/45. Cardiac amyloidosis presenting with elevations of cardiac troponin i and angina pectoris.We present the case of a 43-year-old male who was initially evaluated for angina pectoris and dyspnea. His CK, CK-MB, and cTnI were all elevated following a blood transfusion and he underwent coronary arteriography, which demonstrated no luminal obstructions. After several months, he was transferred to Mayo Clinic where diagnoses of fulminant cardiac amyloidosis and systemic multiple myeloma were established. The cTnI remained elevated despite normalization of the CK and CK-MB. Despite aggressive treatment, the patient died. Postmortem analysis demonstrated amyloid cardiac deposition including involvement of the coronary microvasculature. Electron microscopy revealed myocyte compression injury from amyloid infiltration. We believe this is the first report of elevated troponin i in a patient with cardiac amyloidosis. The electron microscopy in our case confirms cardiac damage as the mechanism for cTnI elevation. This observation strengthens our knowledge about the specificity of cTnI for the detection of cardiac injury.- - - - - - - - - - ranking = 0.4keywords = coronary (Clic here for more details about this article) |
10/45. Divided right atrium associated with extensive coronary vein abnormalities.This report describes a case of a divided right atrium associated with coronary vein abnormalities. An 18-year-old woman who had a past history of surgery for repair of a divided right atrium and atrial septal defect developed exertional dyspnea 8 years after the surgery. Selective coronary angiography showed a dilated right coronary artery with a fistulous communication to the right atrium, tortuous coronary veins draining directly into the cardiac chambers, and the absence of the coronary sinus. Embryologically, regression failure of the right venous valve is hypothesized to have created both the divided right atrium and extensive coronary vein abnormalities.- - - - - - - - - - ranking = 2keywords = coronary (Clic here for more details about this article) |
