Endocarditis complicating a congenital quadricuspid aortic valve.
The most common aortic valve congenital abnormality is observed in bicuspid aortic valve. Only a few cases of aortic valve quadricuspidy have been reported in the literature. We report a new case of endocarditis complicating a congenital quadricuspid aortic valve.
متن کاملBalloon Dilation of Congenital Aortic Valve Stenosis
We evaluated dilation technique (n=80) and aortic valve morphology by two-dimensional echocardiography (n = 58) in patients with congenital aortic valve stenosis to determine their influence on outcome. Patients' age (9 ± 9 years; range, 1 day-39 years) and a history of surgical valvotomy did not influence outcome. The number of dilating balloons (one vs. two) and balloon:annulus ratio based on...
متن کاملMechanisms underlying aortic dilatation in congenital aortic valve malformation.
BACKGROUND The high incidence of aortic disease in subjects with congenital aortic valve malformations suggests a causative relationship between these 2 conditions. The histological observation in aortic dilatation/aneurysm/dissection is Erdheim cystic medial necrosis (CMN), a noninflammatory loss of smooth muscle cells (SMCs), fragmentation of elastic fibers, and mucoid degeneration. METHODS...
متن کاملDissecting aortic aneurysm associated with congenital bicuspid aortic valve.
Among 119 cases of fatal dissecting aneurysm of the aorta, exclusive of those iatrogenically caused or associated with arachnodactyly or aortic stenosis, there were observed 11 cases of congenital bicuspid aortic valve (9%). The ages ranged from 17 to 69 years, five of the patients being 29 years old or younger. Among the latter, three had coarctation of the aorta and one had Turner's syndrome ...
متن کاملPathological Investigation of Congenital Bicuspid Aortic Valve Stenosis, Compared with Atherosclerotic Tricuspid Aortic Valve Stenosis and Congenital Bicuspid Aortic Valve Regurgitation
BACKGROUND Congenital bicuspid aortic valve (CBAV) is the main cause of aortic stenosis (AS) in young adults. However, the histopathological features of AS in patients with CBAV have not been fully investigated. METHODS AND RESULTS We examined specimens of aortic valve leaflets obtained from patients who had undergone aortic valve re/placement at our institution for severe AS with CBAV (n = 2...
