Arterial elastance and heart-arterial coupling in aortic regurgitation are determined by aortic leak severity.
BACKGROUND In aortic valve regurgitation (AR), aortic leak severity modulates left ventricle (LV) arterial system interaction. The aim of this study was to assess (1) how arterial elastance (E(a)), calculated as the ratio of LV end-systolic pressure and stroke volume, relates to arterial properties and leak severity and (2) the validity of E(a)/E(max) (with E(max) the slope of the end-systolic ...
متن کاملAortic regurgitation after arterial switch operation.
n the early 1980s, Jatene developed the arterial switch peration (ASO), which soon became the preferred surgery or d-loop transposition of the great arteries (TGA). This peration includes translocation of the pulmonary artery and orta above the sinuses, often with a Lecompte maneuver bringing the pulmonary artery anterior to the aorta) and oronary reimplantation into the neo-aortic sinuses. Alh...
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 کاملLong-term predictors of aortic root dilation and aortic regurgitation after arterial switch operation.
BACKGROUND Neo-aortic root dilation (ARD) and neo-aortic regurgitation (AR) may be progressive after arterial switch operation (ASO) for d-loop transposition of the great arteries (dTGA). We sought to identify predictors of ARD and AR after ASO. METHODS AND RESULTS 335 patients were identified who underwent ASO for dTGA with intact ventricular septum or ventricular septal defect (VSD), includ...
