A 67-year-old man with grade 3 aortic valve regurgitation was found to have a quadricuspid aortic valve. The aortic valve consisted of 1 large, 2 intermediate and 1 small sized cusp. An accessory cusp located between the right and noncoronary cusps, and shaped like a hammock which sling by the fibrous strings originating from the both commissures to the aortic wall. Aortic valve replacement was...

1 of 2 DESCRIPTION A 29-year-old woman presented with pulmonary oedema and low cardiac output. Her mitral valve was replaced 20 years back with a Sorin mechanical valve. She had stopped anticoagulants a month back on her own for excessive menstrual bleeding. Echo showed a gradient of 26 mm Hg across the valve with regurgitation. Fluroscopy confi rmed limited disc opening of only 15° with incomp...

Method Thirty consecutive patients undergoing aortic valve replacement using the St. Jude Medical Trifecta valve at a single UK centre over a 48-month period were included in this study. Patients undergoing concomitant cardiac procedures were included. All implanted valves were 21, 23, 25 and 27 mm in size. Assessment of haemodynamic function was carried out using transthoracic echocardiography...

Stress evaluation was carried out in 26 patients approximately 7 months after aortic valve replacement with Björk-Shiley valves (13 patients) and St. Jude medical valves (13 patients). During isoproterenol infusion (0.3 micrograms/kg/min), cardiac output increased by a factor of 1.5 and aortic valve area decreased by 50% for both valve groups, while transvalvular gradients (rest: 7 +/- 2 vs 10 ...

Stress evaluation was carried out in 26 patients approximately 7 months after aortic valve replacement with Bjork-Shiley valves (13 patients) and St. Jude medical valves (13 patients). During isoproterenol infusion (0.3 gg/kg/min), cardiac output increased by a factor of 1.5 and aortic valve area decreased by 50% for both valve groups, while transvalvular gradients (rest: 7 ± 2 vs 10 ± 5 mm Hg,...

microembolic signals (mes) are frequently observed in transcranial ‎doppler (tcd) recordings of patients with mechanical heart valve (mhv). if gaseous bubbles are the underlying cause, number of mes produced by mhv could be reduced with oxygen ‎inhalation. from september 2003 to september ‎2004, a consecutive series of 14 patients ‎with st jude aortic valve visited in the cardiology clinic were...

Method One hundred and seventy two consecutive patients undergoing aortic valve replacement using the St. Jude Medical Trifecta valve at a single UK centre over a 48-month period were included in this study. Patients undergoing concomitant cardiac procedures were included. All implanted valves were 19, 21, 23, 25, 27 & 29 mm in size. Patients underwent both pre-operative and post-operative tran...

After follow up for seven years a 10 year old boy with congenital aortic regurgitation was found to have a tricuspid non-stenotic aortic valve at operation. The right coronary cusp was dysplastic, thickened, and contracted; the gap between its free margin and aortic wall was bridged with two fibrous bands; and the left coronary and non-coronary cusps were almost normal. The aortic valve was rep...

A 53-year-old woman who had undergone aortic valve replacement with a Starr-Edwards (S-E) valve (Model 1260) and open mitral commissurotomy 28 years previously was hospitalized with cardiac failure. Echocardiography showed mitral stenosis, mitral regurgitation, and a normally functioning S-E prosthesis. At reoperation, the mitral and aortic valves were replaced with St Jude bileaflet mechanical...
