BACKGROUND Risk factors for developing heart valve and ascending aortic disease are based mainly on retrospective data. To elucidate these factors in a prospective manner, we have performed a nested case-referent study using data from large, population-based surveys. METHODS AND RESULTS A total of 777 patients operated for heart valve disease or disease of the ascending aorta had previously p...
We present a case of an 82-year-old male patient with history severe mitral regurgitation, aortic chronic atrial fibrillation, and suicide attempts due to depression. The underwent valvuloplasty valve replacement for regurgitation regurgitation. was extubated on the morning sixth postoperative day, but he reintubated in evening because hypotension unstable respiratory status. Echocardiography r...
The phenotypic expressions of the bicuspid aortic valve (BAV) are unpredictable, and difficult to compartmentalize. In current times BAV is noted represent approximately 50% isolated severe stenosis cases requiring surgery, has been associated with regurgitation, bacterial endocarditis dissection. Echocardiography diagnostic test identify BAV. clinical associations coupled high prevalence have ...
BACKGROUND Human tissue valves for aortic valve replacement have a limited durability that is influenced by interrelated determinants. Hierarchical linear modeling was used to analyze the relation between these determinants of durability and valve regurgitation measured by serial echocardiography. METHODS AND RESULTS In adult patients, 218 cryopreserved aortic allografts were implanted with t...
BACKGROUND Aortic valve disease is associated with eccentric or concentric left ventricular (LV) hypertrophy and changes in the LV mass. The relationship between LV mass and function and the effect of LV remodeling after aortic valve replacement (AVR), in patients with aortic valve disease needs evaluation, that is largely unknown in our population. The aim of this study was to evaluate the eff...
BACKGROUND The relationship of aortic valve dysfunction and ascending aortic aneurysm is unclear in adults with bicuspid aortic valve disease. METHODS We retrospectively studied 134 consecutive out-patients (98 men, 36 women aged 43 ± 18 years) with bicuspid aortic valve disease. To investigate the relationship of ascending aortic aneurysm and aortic valve dysfunction we exclusively considere...
Angiographic techniques have been used for the quantification of mitral or aortic and rarely tricuspid regurgitation. Mitral or aortic regurgitant volume per beat and the regurgitation fraction (fao and fm, respectively) are obtained from the angiographic determination of total left ventricular stroke volume (TSV) and forward stroke volume (FSV) estimated by a different technique. Although this...
OBJECTIVE The present study was aimed to assess the results of newly developed aortic valve repair technique. METHODS Between 1997 and 2004, 69 aortic valvuloplasties were performed with a new technique addressing the three main components of the aortic root; leaflets (L), sinotubular junction (STJ), and aortic annulus (A). For leaflet correction, additional leaflets were implanted and for ST...
Aortic valve repair with either the reimplantation of aortic or root remodelling external annuloplasty procedure is most effective means treating regurgitation and/or aneurysms [...]
Background: Pulmonary valve stenosis (PS) is one of the most common congenital heart disease in children. Isolated pulmonary stenosis is the most common form of pulmonary stenosis. Isolated Pulmonary stenosis is responsible for 8 to 10 percent of congenital heart disease. Balloon valvuloplasty is the choice of treatment for this cardiac disease. One of the most important complications of this d...
