PURPOSE To evaluate the long-term results of stent placement in the renal arteries. PATIENTS AND METHODS From January 1990 to August 1994, 59 hypertensive patients underwent 64 stent placement procedures. Indications were residual stenosis after percutaneous transluminal renal angioplasty in 42 patients, restenosis in 20 patients, and acute dissection in(More)
PURPOSE To assess the use of a recently developed stent-graft system for treatment of occlusive lesions and aneurysms in the iliac and femoropopliteal arteries. MATERIALS AND METHODS The stent-graft consisted of a nitinol stent framework covered by a thin-walled polyester fabric. The device was used in 105 patients with symptomatic peripheral vascular(More)
BACKGROUND The wide use of percutaneous mitral commissurotomy (PMC) underlines the need to identify the predictive factors of the results. Using a large series allowed us to develop a multivariate model that can be applied to improve patient selection. METHODS AND RESULTS Between 1986 and 1995. PMC was undertaken in 1514 patients. Mean age was 45 +/- 15(More)
Immediate and mid-term results of percutaneous mitral commissurotomy (PMC) were assessed in 75 patients aged > or = 70 years (mean 75 +/- 4 (70 to 86)). Co-morbidities were present in 30 patients (40%), and 58 patients had calcified valves (77%). Technical failure occurred in two patients. PMC was performed in 73 patients, using a single balloon in five,(More)
Percutaneous mitral commissurotomy (PMC) was successfully performed in a 48-year-old woman with dextrocardia and situs inversus and a severe mitral stenosis. After PMC, the valve area increased from 0.97 to 1.89 cm2, and no complication occurred. This case shows that PMC is practicable in a case of dextrocardia with situs inversus. The procedure appears to(More)
To identify the predictive factors of left ventricular dysfunction (LVD) after surgery, we performed an uni- and multivariate analysis of the data concerning 286 patients operated for pure aortic regurgitation between 1980 and 1994 and 460 patients operated for pure non-ischemic mitral regurgitation over a period of 24 years. Among the aortic regurgitation(More)
PURPOSE To evaluate a new self-expanding nitinol coil stent in stenotic or occluded peripheral arteries. METHODS Seventy-three symptomatic patients (58 men; mean age 67 years) were treated with nitinol stents for lesions in the iliac artery (9 stenoses); superficial femoral artery (SFA) (39 stenoses, 6 occlusions); popliteal artery and tibioperoneal trunk(More)
OBJECTIVES This study sought to assess late functional results after successful percutaneous mitral commissurotomy and to determine their predictors. BACKGROUND Few studies have reported late results of percutaneous mitral commissurotomy or have analyzed their late results regardless of immediate results, despite the fact that late deterioration may well(More)
Aortic valve area determination by transesophageal planimetry and by the continuity equation was compared with hemodynamic measurements in 45 patients with symptomatic aortic stenosis. The correlations between transesophageal echocardiography and hemodynamics were dependent on the amount of valvular calcium, whereas the continuity equation correlated well(More)
