To test the hypothesis that the fall in supravalvular aortic diastolic pressure is relative to the severity of the regurgitant flow in aortic regurgitation, 27 patients with isolated aortic regurgitation, 23 patients with combined aortic regurgitation and stenosis, and 15 normal subjects were studied. Diastolic pulse pressure (pressure at the dicrotic notch minus pressure at end diastole) and t...
Background and purpose: The purpose of the study was to asses the natural and clinical course of isolated ventricular defect in children. Materials and methods: Patients and Methods: From 1997 to 2011 we prospectively studied a total of 218 infants and children diagnosed as isolated ventricular septal defects. The Çhi-squar or Fisher exact Test and ÂNÔVÂ were used to compare the difference...
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 ...
Background The quantification of valvular regurgitation by CMR is usually a second-line diagnostic tool that is used when echocardiography has proven inconclusive. According to guidelines are aortic and mitral regurgitations considered severe if the regurgitation volume > 60 ml and regurgitation fraction > 50 %. Regurgitation of a single heart valve may be calculated by comparing LVSV and RVSV ...
SUMMARY To test the hypothesis that the fall in supravalvular aortic diastolic pressure is relative to the severity of the regurgitant flow in aortic regurgitation, 27 patients with isolated aortic regurgitation, 23 patients with combined aortic regurgitation and stenosis, and 15 normal subjects were studied.

BACKGROUND Bicuspid aortic valve regurgitation can be caused by a defect in the valve itself or by dysfunction of one or more components of the aortic root complex. A successful repair thus requires correction of all aspects of the problem simultaneously. We review our experience addressing both the valve and the aortic root when correcting bicuspid valve regurgitation. METHODS AND RESULTS Be...
OBJECTIVE To document the development of aortic regurgitation following occlusion of a patent arterial duct. DESIGN Case series involving nine children referred for surgical ligation of an isolated patent arterial duct. SETTING Academic referral centre. METHODS A preoperative transthoracic and transoesophageal echocardiogram was performed in theatre to look for aortic regurgitation. There...
