Mary Keith,Amir Geranmayegan,Michael J. Sole,Regina Kurian,Andrew Robinson,Ahmad S. Omran,Khursheed N. Jeejeebhoy +6 more
TL;DR: In this paper, the markers of lipid peroxidation and defenses against oxidative stress in patients with varying degrees of congestive heart failure were studied, and the prognosis of these patients was established by measuring the levels of soluble tumor necrosis factor-alpha receptors 1 and 2 (sTNF-R1 and sTNFR2).
Journal ArticleDOI
Long-term results of mitral valve repair for myxomatous disease with and without chordal replacement with expanded polytetrafluoroethylene sutures
TL;DR: Mitral valve repair was feasible in most patients with mitral regurgitation caused by myxomatous disease and it was associated with low rates of valve-related complications, and chordal replacement with expanded polytetrafluoroethylene sutures had no effect on any of these end points.
Journal ArticleDOI
Angiotensin-I Converting Enzyme Genotypes and Left Ventricular Hypertrophy in Patients With Hypertrophic Cardiomyopathy
Marcel E. Lechin,Miguel A. Quinones,Ahmad S. Omran,Rita Hill,Qun Tao Yu,Harry Rakowski,Douglas Wigle,C. C. Liew,Michael J. Sole,Robert Roberts,Ali J. Marian +10 more
TL;DR: ACE genotypes influence the phenotypic expression of hypertrophy in HCM, and LVMI and LVH score were also greater in patients with DD than in those with ID and II genotypes.
Journal ArticleDOI
Results of aortic valve-sparing operations.
TL;DR: Aortic valve-sparing operations have provided excellent clinical outcomes and few valve-related complications, and the function of the reconstructed aortic root remains unchanged in most patients during the first 5 years of follow-up.
Journal ArticleDOI
Mitral regurgitation in hypertrophic obstructive cardiomyopathy: relationship to obstruction and relief with myectomy.
Eric H.C. Yu,Ahmad S. Omran,E. Douglas Wigle,William G. Williams,Samuel C. Siu,Harry Rakowski +5 more
TL;DR: For patients with hypertrophic obstructive cardiomyopathy and MR not due to independent mitral valve disease, myectomy significantly reduced the degree of MR, without requirement for additionalMitral valve surgery.
