We selected 40 patients with severe symptomatic rheumatic mitral stenosis for balloon valvotomy using the Inoue balloon technique. The patients' mean age was 31 +/- 14 years and there were 24 females and 16 males. The patients were selected according to the following echo/Doppler criteria; 1. Severe mitral stenosis, i. e. mitral valve area (MVA) less than 1.1 cm2; 2. pliable anterior mitral val...

Aims: The purpose of this study was to determine whether there is any association between the optimal increase in mitral valve area and mitral transvalvular gradient decrement and pulmonary arterial pressure decrement after balloon mitral valvuloplasty (BMV) in patients with mitral stenosis. Methods: The study population consisted of 49 patients (47 women, 2 men; mean age = 43.7±13.35 years) wi...

BACKGROUND There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy. However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral ba...

The slope of the posterior left ventricular wall motion in diastole (LVDS) was determined by echocardiography in 25 normal subjects and 21 patients with mitral stenosis. Patients with mitral stenosis had reduced LVDS that was related to the degree of mitral stenosis determined by calculated mitral valve area (r = 0.92). The mitral valve area correlated more closely with the LVDS than with the l...

The surgical procedures used to treat mitral valve disease have changed in the last 30 years. The aim of this study was to assess trends in surgical procedures for mitral valve disease at the Jikei University Hospital. From 1972 to 2003,770 patients with mitral valve disease underwent one of following procedures in our department:closed mitral commissurotomy,open mitral commissurotomy,mitral va...

PURPOSE To evaluate long-term survival and valve-related complications as well as prognostic factors for mid- and long-term outcome after closed mitral commissurotomy, covering a follow-up period of 14 years. MATERIAL AND METHODS Between 1989 and 2003, 36 patients (28 women and 8 men, mean age 28.8 +/- 6.1 years) underwent closed mitral commissurotomy at our institution. The majority of patie...

A quantitative assessment of mitral valve orifice area can be achieved in patients with pure mitral stenosis by cardiac catheterization. In the presence of mitral regurgitation, however, accurate measurement often is impossible because total diastolic flow through the mitral valve frequently is unknow. Using a recently developed real-time, two-dimensional echocardiography system, we are able to...

BACKGROUND To investigate the association between the coaptation height of mitral valve and mitral regurgitation after mitral valve repair. METHODS From Sep 2014 to Jun 2015, 20 patients underwent mitral valve valvuloplasty for mitral regurgitation were included. Ring annuloplasty was performed in all cases. Mitral valve short-axis dimension (MVd), coaptation height (CH), Left ventricular eje...

T he hammock mitral valve is a rare congenital abnormality resulting in mitral stenosis, mitral regurgitation, or both. Although sometimes technically challenging, the repair of such lesion is possible and should be preferred to mitral valve replacement. We describe here for the first time the case of an adult patient who underwent mitral valve repair for severe mitral regurgitation related to ...

Percutaneous mitral balloon valvotomy (PMV) has been accepted as an alternative to surgical mitral commissurotomy in the treatment of patients with symptomatic rheumatic mitral stenosis. Previous studies have demonstrated that PMV produces good immediate and long-term follow-up results in a selected group of patients with mitral stenosis.1-4 Hemodynamic and clinical improvement is achieved in t...
