Late results after successful percutaneous mitral commissurotomy were assessed by prospective clinical and echocardiographic follow-up. Fifty-seven patients were followed for a mean of 19 +/- 6 months (range 9 to 33) after the procedure. Mitral valve area (measured by Doppler half-time method) increased from 1.0 +/- 0.2 to 2.2 +/- 0.5 cm2 immediately after(More)
AIMS The choice of resynchronization therapy between with (CRT-D) and without (CRT-P) a defibrillator remains a contentious issue. Cause-of-death analysis among CRT-P, compared with CRT-D, patients could help evaluate the extent to which CRT-P patients would have additionally benefited from a defibrillator in a daily clinical practice. METHODS AND RESULTS(More)
Balloon mitral commissurotomy (BMC) was performed in 113 patients. Of these patients, 27 (24%) (25 women and 2 men, aged 49 +/- 13 years) had recurrent mitral stenosis 13 +/- 6 years (range 5 to 29) after surgical commissurotomy. Eleven patients (41%) were considered at high risk for surgery. BMC resulted in an increase in mitral valve area from 1.1 +/- 0.3(More)
Percutaneous mitral valvuloplasty (PMV) was performed by the anterograde transseptal approach (double balloon technique) in 154 patients with symptomatic mitral stenosis. The mean age of the patients was high (53 +/- 14 years), 87% were women, 68% were in functional Classes III or IV of the NYHA and 37 (24%) had previously undergone surgical commissurotomy.(More)
The aim of this study was to determine the diagnostic efficiency of transesophageal echocardiography (TEE) in isthmic aortic ruptures and to describe the echocardiographic Doppler anomalies. TEE was performed prospectively for 18 months in 33 patients with serious polytraumas requiring intensive care. The average age was 40.75 years (range, 17 to 78 years).(More)
Hypertrophic cardiomyopathy (HCM) is currently considered to be a condition characterised by abnormal diastolic function, sometimes associated with left ventricular outflow obstruction which appears to be a secondary phenomenon. It is important to avoid overlooking this diagnosis especially in young subjects, because of the risk of sudden death, but(More)
Eighteen patients with pure aortic stenosis without coronary artery disease underwent equilibrium radionuclide angiography to evaluate the adaptation of their left ventricular function to exercise. The left ventricular ejection fraction, peak left ventricular ejection, and fillings, and their timing were calculated from time-activity curves and their first(More)
Single photon emission computed tomography (SPECT) is superior to conventional radionuclide scintigraphy. The most widely used marker is thallium-201, despite the fact that it is not exclusively flow-dependent. Thallium-201 SPECT can be performed in patients at rest, during exercise followed by a redistribution study, under dipyridamole or nitrate infusion,(More)
In order to study the results of percutaneous mitral valvuloplasty (PMV), subvalvular mitral disease was classified using: 1) the transthoracic echo score (0-4), 2) an index derived from left ventricular angiography defined as the ratio of the distance from the extremity of the papillary muscle and the mitral valve in systole and the distance between the(More)
