Echocardiography of the aortic valve. I. Studies of normal aortic valve, aortic stenosis, aortic regurgitation, and mixed aortic valve disease.
necropsy. The normal aortic valve echocardiogram is described and evidence is given that the anteriorly visualized cusp echoes arefrom the right coronary but those which are posteriorly visualized may befrom the non-coronary or the left coronary cusp. The ultrasound patterns in aortic stenosis, aortic regurgitation, and mixed aortic valve disease are described. In each case the aortic root diam...
متن کاملAortic Valve replacement with Reduction Aortoplasty with Mesh Prosthesis in 75 years old with Sever aortic Regurgitation with Aortic Aneurysm
Although classic and standard procedure for patients with ascending Aorta aneurysm with Sever aortic Regurgitation is Bentall surgery but in some selected cases this complex surgery was not performed with different reason like advanced age and coexisting comorbidity involving renal and hepatic and lung Function. In our cases 75 years old man with chronic renal failure ( Cr= 3.2 ) who was known ...
متن کاملValve sizing for pure aortic regurgitation during transcatheter aortic valve replacement: deformation dynamic of the aortic annulus in different valve pathology may be different.
We read with great interest the report by Seiffert et al. (1) on the initial German experience with transapical implantation of a second-generation transcatheter heart valve for the treatment of aortic regurgitation. With the development of second-generation transcatheter aortic value replacement (TAVR) devices, TAVR indications have been expended to high-risk patients with pure aortic regurgit...
متن کاملQuadricuspid aortic valve: a rare cause of aortic regurgitation and stenosis.
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 ...
متن کاملAortic regurgitation after transcatheter aortic valve replacement.
Paravalvular aortic regurgitation (AR) negatively affects prognosis following transcatheter aortic valve replacement (TAVR). As transcatheter heart valves (THV) are anchored using a certain degree of oversizing at the level of the aortic annulus, incomplete stent frame expansion because of heavily annular calcifications, suboptimal placement of the prosthesis, and/or annulus-prosthesis size-mis...
