OBJECTIVES To evaluate the significance of involvement of subvalvular apparatus in the outcome of percutaneous mitral balloon valvotomy (PMBV) in patients with mitral stenosis (MS) and to determine the predictive value of chordal length compared with current echocardiographic scores. METHODS Patients with significant MS were selected according to the Massachusetts General Hospital score (MGHS...
Percutaneous balloon dilatation was attempted in 15 consecutive neonates (mean age 7.3 (range 1-27) days and weight 3.2 (range 2.5-4.1) kg) with critical stenosis of the pulmonary valve. Dilatation was successful in 11 (73%) patients. The mean balloon to annulus ratio was 1.1 (range 0.6-1.77). The ratio of right ventricle to femoral artery systolic pressure decreased from a mean (1 SD) of 1.4 (...
We have studied the long-term growth and development of seven infants who had been exposed during the foetal stage to ionising irradiation associated with percutaneous balloon mitral valvuloplasty between 1 April 1991 and 30 November 1993. We found that infants of mothers who underwent this procedure during the second and third trimester of pregnancy had normal long-term growth and development....
INTRODUCTION AND OBJECTIVES The left atrium is clinically relevant in patients with mitral valve stenosis. The objective of this study was to analyze the effects of percutaneous balloon valvuloplasty on left atrium volumes and the left atrium emptying fraction in symptomatic mitral valve stenosis patients using 2-dimensional and real-time 3 -dimensional transthoracic echocardiography. METHODS...
Introduction : Patients with hemodynamically significant mitral stenosis (MS) have prolonged P-wave duration and increased P-wave dispersion (PWD) that decrease after successful percutaneous balloon mitral valvotomy (PBMV). The purpose of this study was to investigate if the changes in these indices may predict a successful procedure. Methods : Fifty two patients with MS in sinus rhythm underwe...
