Preliminary results of 130 aortic valve replacements with a new mechanical bileaflet prosthesis: the Edwards MIRA valve.
We present a series of 130 consecutive patients operated for aortic valve replacement (AVR) using the standard MIRA prosthesis between January 1999 and March 2001. Most of the patients were male (sex ratio = 2) with a mean age of 61.5 +/- 9.5 years. The prosthesis was implanted using the continuous suture technique. The mean diameter of the implanted prostheses was 23 mm. This series was compos...
متن کاملFive-year follow-up after heart valve replacement with the CarboMedics bileaflet prosthesis.
BACKGROUND The CarboMedics valve is a relatively new, low-profile, bileaflet, mechanical prosthesis. The results of a prospective follow-up study after valve replacement with this prosthesis in a university hospital are presented. METHODS We implanted 640 CarboMedics prostheses in 583 patients in the aortic (n = 359), mitral (n = 167), or aortic and mitral positions (double valve replacement;...
متن کاملEarly clinical experience with the Hancock porcine xenograft valve prosthesis.
In a 2-year period, 75 Hancock porcine xenograft valves were inserted in 66 patients, 33 male and 33 female. Their average age was 55 years (range 14 to 69 years). The indication for operation was rheumatic heart disease (30 patients), prosthetic valve dysfunction (8 patients), papillary muscle dysfunction (8 patients), degenerative valve disease (13 patients), subacute bacterial endocarditis (...
متن کاملStructural analysis of a bileaflet mechanical heart valve prosthesis with curved leaflet
Structural analysis, especially the thickness effect on the structural strength, of a bileaflet mechanical heart valve prosthesis with curved leaflets is presented in this paper. Taking the wide variations of the blood flow pressure on the leaflet surface, the structural stresses inside the leaflet and deflections of the leaflet are investigated by adopting both linear and nonlinear structural ...
متن کاملA bileaflet CarboMedics aortic valve prosthesis with a new unusual "linear" central regurgitant jet: a sign of subtle incomplete closure of one leaflet?
Figure 1. Parasternal imaging in diastole. A. Long-axis image—a prosthetic valvular color jet directed toward the interventricular septum (arrow). (LA = left atrium; LV = left ventricle). B. Short-axis image—the diastolic jet appears to be “central valvular” and “linear” in shape (arrow). (RVOT = right ventricular outflow tract). A 76-year-old retired physician underwent routine follow-up echoc...
