Abstract Background: Renal insufficiency is a potential complication after infrarenal abdominal aortic aneurysm repair and is a significant risk factor for postoperative mortality and morbidity. The aim of this study was to analyze the effect of this risk factor, before and during operation. Methods: In this prospective study, between 2003 and 2006, 45 patients underwent repair of an infrarena...

Acute aortic valvular insufficiency was induced in open chest dogs by employing a special intravascular cannula, or by rupturing an aortic valve leaflet. Phasic and mean coronary flow were assessed in some animals, while in others data were obtained on arterial and coronary sinus blood lactate, pyruvate, P(O2), P(CO2), and pH, and on myocardial tissue lactate, pyruvate, and water content in the...

A 48-year-old male with history of chronic arthritis and uveitis presented with 1 year of progressively reduced exercise capacity and nonexertional chest pain. Physical examination was consistent with severe aortic insufficiency. An electrocardiogram demonstrated sinus rhythm with first degree atrioventricular block. Transthoracic and transesophageal echocardiography demonstrated severe lone ce...

a 31 year old woman was hospitalized for evaluation of aortic valve insufficiency and her present cardiac status. clinical and paraclinical findings strongly suggested the presence of a collagen vascular inflammatory processprecisely, the antiphospholipid antibody syndrome (aps), with systemic lupus erythematosus as the underlying disease.

background: recent interests have mainly focused on the roles of serum calcium and phosphorus and their product (ca-p product) in the development of valvular heart disease. the present study assessed the relationship between the ca-p product and the severity of valvular heart disease in end-stage renal disease (esrd) patients undergoing chronic hemodialysis. methods: this cross-sectional study ...

a total of 14 cases of infective endocarditis (ie) in children aged 6 months to 10 years were seen from december 1987 to december 1992 at the pediatric unit of ayatollah taleghani medical center. the majority of patients (12 of 14) were between 5 and 10 years of age. acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. organis...

When a diastolic murmur is present at the base of the heart, it may be difficult on clinical grounds to determine whether or not aortic insufficiency is present. Further, in patients in whom this lesion definitely exists, the magnitude of aortic regurgitant flobe, has been the subject of considerable speculation among both clinicians and physiologists. A technic has been devised that not only m...

A survey was ma(le of the clinical usefulness of pulse forms from direct brachial arterial puncture of 250 patients. A prolonged duration of systolic upstroke and an anacrotic notch were found in most instances of severe aortic stenosis, but also frequently in patients with insignificant degrees of aortic stenosis, and occasionally in normal subjects. Characteristic, but nondiagnostic changes i...
