Hemodynamic factors that affect calculated orifice areas in the mitral hancock xenograft valve.
From June 1974 to December 1978, 714 Hancock valves have been placed in 605 patients. One hundred seventy-five patients with a mitral xenograft have been restudied. The results were questionable due to the wide scatter and disparity between the calculated and the theoretical orifice of each valve size. To elucidate these differences, the hemodynamic data of 40 isolated, normal functioning mitra...
متن کاملIntermediate term results of isolated mitral valve replacement with glutaraldehyde-preserved porcine xenograft valve: clinical and hemodynamic comparison between Hancock valve and Angell-Shiley valve.
Clinical and hemodynamic assessments were carried out for 30 cases, who underwent isolated mitral valve replacement with glutaraldehyde-preserved porcine xenograft valve. The cases were divided into two groups, according to the types of prostheses. Group H comprised 23 cases with Hancock 342 valve and group AS, 7 cases with Angell-Shiley valve. Mean (S.D.) follow-up periods were 4.0 +/- 0.7 in ...
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 کاملBalloon Mitral Valvuloplasty in Rheumatic Double Orifice Mitral Valve
We are reporting four cases of acquired double orifice mitral valve (DOMV) of rheumatic etiology (rare) presenting as significant mitral stenosis (MS) treated successfully by percutaneous intervention. All four patients are young (3 males, 1 female) who presented with dyspnea of Newyork heart association (NYHA) class II with mean duration of 1.3 years. Typical clinical findings of MS were prese...
متن کاملDouble-orifice mitral valve - echocardiographic findings.
BACKGROUND Double-orifice mitral valve (DOMV) is a rare congenital malformation characterised by the presence of two orifices in the left atrio-ventricular valve area, each having an independent chordal attachment to the papillary muscle. AIM To establish the echocardiographic features and incidence of DOMV in patients undergoing an echo study in a tertiary referral centre. METHODS We carri...
