Background: Successful mitral valve repair and replacement are dependent upon a full understanding of normal and abnormal mitral valve anatomy and function. The functional components of the mitral valve include: the left atrial wall, the annulus, the leaflets, the chordae tendineae, the papillary muscles, segments of the left ventricular myocardium. Abnormal anatomy or function of any one of th...

OBJECTIVES (a) To assess the echocardiographic incidence of restenosis after successful balloon dilatation of the mitral valve at a mid-term follow up of one year among a population of predominantly United Kingdom patients. (b) To identify any factors, assessed before or during dilatation, which may predict the development of restenosis. DESIGN Successful dilatation of the mitral valve was de...

Over the past few decades, it has become apparent that mitral valve repair is preferable to mitral valve replacement for the majority of patients undergoing surgery for mitral regurgitation (MR). The advantages of mitral valve repair include low rates of thromboembolism, resistance to endocarditis, excellent late durability reported for as long as 25 years, and no need for anticoagulation in th...

In cases of old myocardial infarction, the presence of mitral valve regurgitation is one of the predicting factors of long-term prognosis. The mechanism of ischemic mitral regurgitation consists of mitral annular dilatation, left ventricular (LV) dilatation followed by tethering of the mitral valve, etc. Since long-term prognosis of the patients in whom the degree of mitral valve regurgitation ...

From Cutler’s first attempt to treat the mitral valve by inserting a tenotomy knife through the left ventricle, to Carpentier’s introduction of several repair techniques and a functional classification for assessing mitral valve lesions, the history of mitral valve treatment is exciting. Mitral diseases may be degenerative, ischaemic, infective or rheumatic, with or without superimposed impaire...

Primary cardiac tumors are rare and myxoma is the most common tumor among them. Cardiac myxoma usually occurs in the left atrium. Myxoma originating from mitral valve is extremely rare. We report a case of mitral valve myxoma. The tumor originated from the anterior mitral valve leaflet. The tumor was completely removed and replacement of the mitral valve was not done.

The results of investigation in 5 children with congenital deformities of the mitral valve region characteristic of the 'parachute mitral valve complex' were reviewed. Three patients had parachute mitral valve, i had supravalvar mitral ring, and i had both these lesions. Associated anomalies included ventricular septal defect, double outlet right ventricle, subaortic stenosis, bicuspid aortic v...

Mitral valve repair offers superior long-term survival, freedom from cardiac morbidity, and quality of life in patients with severe mitral regurgitation compared to medical management and mitral valve replacement; it is the treatment of choice in these patients. Mitral valve repair is the only treatment that restores normal life expectancy to otherwise healthy patients with advanced degenerativ...

The interrelation between the loudness of the first heart sound, the time interval from the Q wave to the onset of the first heart sound (QM1), and the mitral valve closure rate was studied in nine patients presenting with left atrial myxomata. In seven patients the first heart sound was loud preoperatively and was associated with delayed mitral valve closure. After removal of the myxoma the on...

A real-time, phased-array, two-dimensional echocardiography system was used to assess mitral valve motion in 30 catheterized patients with pure mitral stenosis. Suitable images for analysis of mitral valve motion were obtained in 25 patients. The valve leaflets were most thickened and immobile at the leaflet tips while maximum mobility was at the leaflet body. Diastolic movement of anterior mit...
