Article Up to 50% of acute myocardial infarctions are associated to mitral regurgitation of some degree and 10% of these cases present, at least, moderate regurgitation. Ischemic mitral regurgitation is associated to an increase of mortality and morbidity. For surgical patients with moderate regurgitation, the benefits mitral valve repair remain unclear.  301 patients were randomized...

Aortic regurgitation after valve implantation has been shown to be a long -term mortality predictor. The aim of this study was to test the new Direct Flow Medical system, which is more flexible prosthesis with a lower profile that could result in minor aortic regurgitation and less need for post expansion. This multicenter study included...

So far, there had been no published randomized studies comparing balloon-expandable Edwards’s prosthesis and self-expandingCoreValve. The aim of this study was to compare the results between the two thin aortic prosthesis in high-risk surgical patients with severe symptomatic aortic stenosis undergoing valve replacement by percutaneous transfemoral access. This was a multicenter work (five centers in...

Unlike degenerative mitral insufficiency, ischemic failure is due to an increase in the left ventricular cavity, the loss of its elliptical form, ring dilation and displacement of the papillary muscles leading to the loss of coaptation the leaflets. European and American guidelines suggest the intervention on the mitral valve in patients with ischemic mitral regurgitation...

The objective of the study was to assess events after 30 days with the DirectFLOW Medical Valve device in patients with severe aortic stenosis and high surgical risk. The device is designed to reduce post-implant aortic regurgitation; it has a low profile and high navigability and requires no post-dilatation or rapid pacing. The study included...
