BACKGROUND Leaflet escape is a mode of structural valve failure for mechanical prostheses. This complication previously has been reported for both monoleaflet and bileaflet valve models. We report 2 leaflet escape occurrences observed in 2 patients who underwent valve replacement with a TRI Technologies valve prosthesis. METHODS AND RESULTS At the University of Padua, between November 2000 an...

OBJECTIVES This study observed midterm results of vascular ring connectors in surgery for aortic dissection. METHODS Vascular ring connectors were used as stents in vascular grafts to achieve quick, sutureless anastomoses. Tapes were used to secure ringed vascular grafts from outside the aorta. RESULTS From November 2007 to February 2011, 113 consecutive patients with aortic dissection, exc...

From May 1990 through December 1994, integral valved aortic homografts were implanted for replacement of the aortic valve and of part or the whole of the ascending aorta in 24 patients with a mean age of 45.5 years (17-66 years). Ten patients (41.7%) had infective endocarditis of the aortic valve (4 of the native valve and 6 prosthetic). Seven of these had root abscesses (70%), one with a fistu...

Accurate quantitation of mitral regurgitation offers a major clinical dilemma. The clinical clues depend largely on cardiac auscultation, the accuracy of which needs to be rigorously tested (1). Mitral regurgitation may not be associated with a clinically audible systolic murmur, and the auscultatory features of severity of regurgitation are generally based on increased volume of diastolic flow...

introduction: body mass index (bmi) can affect cardiac morphology; however, the relationship between bmi and valvular heart diseases has not been thoroughly evaluated. this study aimed to determine the relationship between bmi and mitral valve prolapse (mvp) as one of the most common valve diseases worldwide. it can help us to better understand pathophysiology of this common disease. materials ...

Method 10 patients were operated on from January 2009 to January 2014 for lesions of the mitral valve (AVCD were excluded from this study), age was between 04 and 16 years (mean 10 years), 40% male, the lesion was mitral regurgitation in all cases, the lesions were congenital origin in 07 of 10 cases, associated lesions in 20% (2 cases) the presence of atrial septal defect (OS), 10 % (1 case) c...

background: considering suggested formula in the references and pcwp measured by catheterism, in the present study the relation between pulmonary capillary wedge pressure (pcwp) measured the flow velocity of mitral valve and mitral annulus motion through tissue doppler imaging is evaluated methods: 52 cases of severe ms were admitted for balloon mitral valvolotomy (bmv) are included in this stu...

Between December 1981 and April 1984, five children ranging in age from 1 month to 5 1/2 years examined by two-dimensional echocardiography appeared to have a double orifice mitral valve. The diagnosis was verified in one patient at surgery, one patient by angiography and one patient by necropsy. Associated malformations included mitral stenosis and regurgitation, coarctation of the aorta, osti...

introduction: mitral stenosis is a narrowing or blockage of the opening of the mitral valve. symptoms usually develop between the ages of 20 and 50. it most commonly occurs in people who have had rheumatic faver. the purpose of this study was to determine the clinical, characteristics of mitral stenosis in men and women and their reactions to balloon mitral valvotomy (bmv).  materials and metho...

BACKGROUND Beating heart (off-pump) coronary artery bypass grafting (CABG) techniques have led us to consider the possibility of performing mitral valve repairs and replacements (with or without CABG) on the beating heart. METHODS If CABG had to be performed in addition to the valve procedure, CABG was done first on the beating heart without cardiopulmonary bypass, if possible. For the valve ...
