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 کاملSuccessful Use of Two Thrombolytic Drugs in Prosthetic Mitral and Aortic Valve Thrombosis
Introduction: Prosthetic valve thrombosis is a rare and severe complication of valve replacement, most often encountered with a mechanical prosthesis. The significant morbidity and mortality associated with this condition warrant rapid diagnostic evaluation. Although surgery is the first-line therapy in symptomatic obstructive mechanical valve thrombosis, thrombolytic therapy has been used as a...

In recent socio-economic state it is not possible to have different sets of prosthetic cardiac valves available in the operating room before open-heart surgery for valvular replacement. In this study the diameter of the aortic valve ring measured in 2-D echocardiography was compared with the size of the aortic prosthetic valves implanted for the patients with aortic valvular disease. The purpos...
متن کاملEx Vivo Evidence for the Contribution of Hemodynamic Shear Stress Abnormalities to the Early Pathogenesis of Calcific Bicuspid Aortic Valve Disease
The bicuspid aortic valve (BAV) is the most common congenital cardiac anomaly and is frequently associated with calcific aortic valve disease (CAVD). The most prevalent type-I morphology, which results from left-/right-coronary cusp fusion, generates different hemodynamics than a tricuspid aortic valve (TAV). While valvular calcification has been linked to genetic and atherogenic predisposition...
متن کاملHemodynamic factors affecting the fate of valvular bioprosthesis.
Since their introduction in 1969, valvular bioprostheses (ie, glutaraldehyde-processed animal valves)1 have experienced a surprising increase in use as a result of progress in valve processing2 and growing patient desire for nonthrombogenic valve surgery.3 However, the persistent risk of structural valve deterioration, particularly in the young population, remains a major concern. The 2 main ca...
