Congenital   aortocaval   fistula in association with complex congenital heart disease has never been described before. We represent an adult with tetralogy of fallot and an undiagnosed subclavian artery to superior vena cava fistula in previous catheterisms. He underwent surgical correction, successfully. After 8 months post operation he was doing well with improved functional capacity and no ...

OBJECTIVE In heart failure atrial natriuretic peptide (ANP) release in response to volume expansion is impaired while the renin-angiotensin system is activated. This study was designed to test the hypothesis that ANP release in heart failure is dependent on an activated angiotensin system. METHODS We studied the ANP and renin-angiotensin systems in a rat model of shunt-induced high-output hea...

Activation of the renin-angiotensin system may contribute to the derangement in renal and cardiac function in congestive heart failure. The present study evaluated the effects of eprosartan, a selective angiotensin II receptor antagonist, on renal hemodynamic and excretory parameters and on the development of cardiac hypertrophy in rats with aortocaval fistula, an experimental model of congesti...

Spontaneous aortocaval fistula is an uncommon complication of an abdominal aortic aneurysm. This report details two cases of this condition presenting with symptoms attributable to arteriovenous shunting. Pain was not a prominent feature so that attention was not initially drawn to the abdomen. Diagnosis and management of the condition are discussed.

Mucinous cystadenoma (MC) of the ovary is an unilateral, multilocular cystic benign epithelial tumor. Supposed to be hormone responsive, MC reaches huge sizes during pregnancy. Aortocaval compression is common during pregnancy, especially when the pregnant woman is in the supine position. However, the compression recovers with a change in position. The authors report the first case of a huge mu...
