Background Combination hormonal contraceptives are widely used and available in various dosage forms. Thromboembolism is an established risk factor associated with the use of these agents, increased rates arterial thrombosis venous thromboembolism reported. Arterial occurs much less frequently more serious short-term long-term consequences. Aim We report a case aortic thrombus occurring seconda...
In four patients, echocardiography showed duplication of an aortic wall echo. An aortic dissection was present in only one. Other causes for the echocardiographic pattern were abscess in the interventricular septum, mitral stenosis, and dilatation of the noncoronary sinus of Valsalva. Division of the echo from the mitral ring into two separate posterior aortic wall echoes was seen only in the p...
This paper is based largely on personal observations of normal and stenosed mitral valves. Some aspects that are new and some that are not in keeping with present-day concepts will be discussed. The mitral valve is a unit that consists of a so-called fibrous "ring," of two unequal cusps, of two sets of papillary muscles, and of numerous chorde tendinee. When two triangular leaflets are attached...
OBJECTIVES The aim of this study was to provide a detailed description of echocardiographic and Doppler features of pseudoaneurysms involving the mitral-aortic intervalvular fibrosa and to compare echocardiographic and aortographic findings. BACKGROUND Infection of the aortic valve may spread to the aortic annulus, resulting in ring abscesses or pseudoaneurysms, or both, of the intervalvular ...
We report the case of a 26-year-old male patient with 2-week history of Brucella aortic valve endocarditis that was referred from general hospital to our hospital emergency room with pallor of the skin and mucous membranes accompanied by systemic hypotension and chest pain. Trans esophageal echocardiography (TEE) revealed a 30-mm ascending aorta at the pulmonary trunk with no evidence of the fa...
OBJECTIVES The purpose of this study was to determine the frequency of chromosome 22q11 deletions in patients with isolated anomalies of the aortic arch and its branches. BACKGROUND Chromosome 22q11 deletions are often present in patients with certain forms of congenital cardiovascular disease, including tetralogy of Fallot, truncus arteriosus and interruption of the aortic arch. Among patien...
A 43-year old man presented with chest pain and fever. He had inadvertently inhaled a nasal piercing which caused injury to the descending aorta through the left bronchus. The resulting pseu-doaneurysm was treated with endovascular stenting after left carotido-subclavian bypass (Figs 1 and 2). The patient died 2 years later due to drug overdose. Figure 1: CT scan showing the false aneurysm (ast...
IN SPITE OF, and also because of the great progress that has been made in the last decade in both clinical and basic research in the field of cardiovascular disease and in its application to the diagnosis and care of patients with heart disease, exact autopsy findings, in the event of death, have never been more important or more meaningful. With the rapid introduction of new technics, new tool...
The microcirculatory changes caused by hypercholesterolemia were studied in the rat cremaster muscle model by intravital microscopy and were compared with aortic ring segments from the same animals. Male Sprague-Dawley rats were fed either a normal chow diet or a chow diet supplemented with 1% cholesterol and 0.5% cholic acid for 3 or 5 weeks before experimentation. Three weeks of hypercholeste...
