Noirhomme P et al. Valve sparing-root replacement with the reimplanta-tion technique to increase the durability of bicuspid aortic valve repair. David valve-sparing aortic root replacement: equivalent mid-term outcome for different valve types with or without connective tissue disorder. RS et al. Results of matching valve and root repair to aortic valve and root pathology. Repair of the bicuspi...
Many patients with severe aortic stenosis never undergo surgical treatment for various reasons. Apart from the standard risks, some patients face an additional problem: their carrying of a mechanical mitral valve. In these patients, transcatheter aortic valve implantation is a therapeutic option. The literature contains only few reports of this procedure being performed (usually transapically) ...
Calcific aortic valve disease is common, affecting 25% of adults over the age of 65 years, with progression to severe valve obstruction resulting in more than 50 000 aortic valve replacements annually in the United States. “Degenerative” calcific aortic valve disease was thought for many years to be a passive accumulation of calcium binding to the aortic surface of the valve leaflet. Now, convi...
BACKGROUND Aortic valve replacement in a patient with an aortic homograft can be very challenging, especially when concomitant mitral valve surgery needs to be performed. CASE PRESENTATION We report a case of implantation of a sutureless aortic valve bioprosthesis combined with mitral valve replacement in a patient with a severely calcified aortic homograft where conventional valve replacemen...
OBJECTIVES This study sought to report on the pathology of transcatheter aortic valves explanted at early and late time points after transcatheter aortic valve implantation. BACKGROUND Information on pathological findings following transcatheter aortic valve implantation is scarce, particularly late after transcatheter aortic valve implantation. METHODS This study included 20 patients (13 m...
BACKGROUND Treatment of hyperlipidemia produces functional and structural improvements in atherosclerotic vessels. However, the effects of treating hyperlipidemia on the structure and function of the aortic valve have been controversial, and any effects could be confounded by pleiotropic effects of hypolipidemic treatment. The goal of this study was to determine whether reducing elevated plasma...
Twenty-eight patients who underwent aortic valve replacement and coronary artery bypass grafts (group A) were compared, with respect to clinical presentation, operative mortality and morbidity and follow-up clinical status, with 40 patients who had normal coronary arteriograms and underwent aortic valve replacement only (group B). Groups A and B had a similar incidence of angina pectoris, cardi...
BACKGROUND The objective was to evaluate the effects of aortic annulus size on valve hemodynamics and clinical outcomes in those patients included in the Placement of Aortic Transcatheter Valves (PARTNER) randomized controlled trial cohort A and the nonrandomized continued access cohort. METHODS AND RESULTS Patients included the randomized controlled trial (n=574) and nonrandomized continued ...
Aortic Valve Disease, includes a range of disorder severity from mild leaflet thickening without valve obstruction, "aortic sclerosis", to severe calcified aortic stenosis. It is a slowly progressive active process of valve modification similar atherosclerosis for cardiovascular risk factors, lipoprotein deposition, chronic inflammation, and calcification. Systemic signs of inflammation, as wal...
The abnormalities of aortic valve morphology and function represent the most common cardiac-valve lesion particularly in elderly. The etiology of aortic stenosis is degenerative-calcific in the majority of patients. Many risk factors seems to be linked to the calcification and the stenosis of the aortic valve but they must be confirmed. In this review the etiology and the possible physiopatholo...
