Mechanism of elevated innominate artery pressures in supravalvular aortic stenosis.
Patients with supravalvular aortic stenosis frequently have higher phasic and mean blood pressures in the innominate artery than in the aorta distal to the stenosis, a finding never fully explained. Theoretically, this phenomenon could result from the impact of a jet upon blood within the innominate artery. Slowing of the jet would convert kinetic into potential energy, thus increasing pressure...
متن کاملAcquired Infrarenal Abdominal Aortic Coarctation: Treatment with Percutaneous Self Expandable Stent
Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic reso...

Background: Balloon valvuloplasty is a relatively new technique for relief of obstruction of aortic valve. The primary results of this procedure are similar to surgical valvotomy with fewer complications and mortality. Materials and methods: One hundred fifty-five patients with congenital aortic stenosis were enrolled in this study over a period of 6 years (1991-1997). Participants were all un...
متن کاملThe Surgical Treatment of Supravalvular Aortic Stenosis Based on Two Cases
An increasing number of cases of supravalvular aortic stenosis have been reported in recent years. In those hitherto described, the stricture has consisted of either a fibrous membrane directly adjacent to the cusps or a true stenosis at the level of the upper border of the sinus of Valsalva where, as mentioned by Kreel, Reiss, Strauss, Blumenthal, and Baronofsky (1959), a slight, circular inwa...
