Abstract

The publications in 2001 regarding valvulopathies have concerned all sectors of this pathology. Aortic valvulopathies are the object of new work supporting the relationship between aortic sclerosis or stenosis and cardiovascular risk factors. They confirm the analogy between lesions of inflammatory origin observed on calcified valves and atherosclerotic plaques (Mohlner). They find higher rates of serum lipids in the case of valvular replacement for stenosis than for aortic insufficiency albeit in an older population (Novaro). Monin shows the possibility of a better pre-operative prognostic approach for advanced aortic stenoses at low transvalvular gradient with left ventricular dysfunction, for which the post-operative results are better when low dose stress echocardiography has shown the existence of a contractile reserve. For the results of aortic surgery with biological prostheses it is widely reported that they behave as homografts (O'Brien), stented heterografts (Puvimanasinghe) or stent-less (Hubaut). A controversy exists on the subject of the degenerative mechanism of bioprostheses between the supporters of the immunological hypothesis (Human) and those of the purely degenerative hypothesis (Mitchell). This controversy ...Continue Reading

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
