BACKGROUND Type I aortic dissection develops in 0.6% of patients late after aortic valve replacement (AVR), and 13% of patients with type I aortic dissections have a history of AVR. Predictors of aortic dissection at AVR, however, have not been characterized. METHODS AND RESULTS A study group of 33 patients with type I aortic dissection had aortic surgery 49+/-55 months after routine AVR. A g...
BACKGROUND ACTA2 mutations are the major cause of familial thoracic aortic aneurysms and dissections. We sought to characterize these aortic diseases in a large case series of individuals with ACTA2 mutations. METHODS AND RESULTS Aortic disease, management, and outcome associated with the first aortic event (aortic dissection or aneurysm repair) were abstracted from the medical records of 277...
Forteza et al from the Hospital Universitario 12 de Octubre described in this issue of the Revista Española de Cardiología their initial experience with aortic valve sparing operations for aortic root aneurysm in 18 patients with Marfan syndrome. The authors indicated that they have done 40 such operations for aortic root aneurysm. The early results reported are excellent and I commend them for...
Objective: To evaluate the results of two operations, aortic valve-sparing and aortic root replacement, in patients with aortic root aneurysm and the Marfan syndrome. Methods: A retrospective review of 78 consecutive patients with aortic root aneurysm and the Marfan syndrome according to the Gent criteria indicated that 42 patients with normal aortic cusps had an aortic valve-sparing operation,...
Bicuspid aortic valve (BAV) can be both sporadic and hereditary, is phenotypically variable, and genetically heterogeneous. The clinical presentation of BAV is diverse and commonly associated with a high prevalence of valvular dysfunction producing altered hemodynamics and aortic abnormalities (e.g., aneurysm and dissection). The thoracic aortic aneurysm (TAA) in BAV frequently involves the pro...
Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy. Transthoracic echocardiography revealed dilation of the left ventricle, valvular and subvalvular aortic stenosis, bicuspid aortic valve, aortic regurgitation, and mitral valve ...
INTRODUCTION The cause of ascending aortic dilatation occurring in patients with congenitally bicuspid aortic valves was investigated. METHODS Flow patterns through human aortic roots with congenitally bicuspid aortic valves as well as through porcine constricted aortas were studied in a left heart simulator. Vibration was recorded as a measure of turbulence in the post-stenotic segment. Hist...
OBJECTIVE To assess the pattern and progression of aortic valve dysfunction by serial Doppler echocardiographic examinations in ambulatory adult patients with congenital bicuspid aortic valve. DESIGN AND SETTING Retrospective analysis of patients referred for Doppler echocardiography over a four year period. SUBJECTS Fifty one adult patients with echocardiographic diagnosis of congenital bi...
BACKGROUND Current practice guidelines recommend surgical repair of large thoracic aortic aneurysms to prevent fatal aortic dissection or rupture, but limited natural history data exist to support clinical criteria for timely intervention. METHODS AND RESULTS Of 3247 patients with thoracic aortic aneurysm registered in our institutional Thoracic Aortic Center Database, we identified and revie...
cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. in this study, the effect of chronic administration of sesame (sesamum indicum l) seed feeding was studied on aortic reactivity of streptozotocin (stz)-diabetic rats. male diabetic rats received sesame seed-mixed food at weight ratios of 3% and 6% for 7 weeks, one week after diabetes in...
