OBJECTIVES Using two-dimensional echocardiography, we sought to identify features that are associated with severe mitral regurgitation after percutaneous mitral valvulotomy and combine them into a predictive score. BACKGROUND Severe mitral regurgitation after percutaneous mitral valvulotomy is a major complication carrying an adverse prognosis that, to(More)
A total of 318 consecutive patients with mitral stenosis underwent percutaneous mitral valvotomy at our institution from 1987 to 1993. Of those, 98 patients had color Doppler echocardiographic studies performed before, 24 hours after, and late after the intervention. On the basis of color Doppler echocardiographic grading of tricuspid regurgitation, 32(More)
The rate of progression of the degree of chronic aortic regurgitation (AR) is unknown. Furthermore, although left ventricular (LV) dilation has been studied in patients with severe AR, its rate and determining factors, and specifically, its relation to the degree of regurgitation remain to be established and have not previously been studied for mild and(More)
To date, the relation between mitral stenosis (MS) and other associated cardiac valvular lesions has been reported by angiography and surgical pathologic study in patients with more advanced disease but has not been studied systematically by two-dimensional echocardiography and Doppler color flow mapping in a large referral population with a broader(More)
OBJECTIVES The purpose of this study was to determine, in a large referral population, the rate of echocardiographic change in mitral valve area (MVA) without interim intervention, to determine which factors influence progression of narrowing and to examine associated changes in the right side of the heart. BACKGROUND Little information is currently(More)
BACKGROUND Patients with a left ventricular ejection fraction (LVEF) of less than 40 % are at high risk of developing postoperative low cardiac output syndrome (LCOS). Despite actual treatments (inotropic agents and/or mechanical assist devices), the mortality rate of such patients remains very high (13 to 24 %). The LICORN trial aims at assessing the(More)
