conclusions preservation of mitral annulus and papillary muscle continuity may enhance post- mvr cardiac performance with low mortality and morbidity rates. the risk of pvd was not significantly higher than conventional mvr in our series. results the improvement of functional status was seen in almost all survivors but was more obvious in the group i. in early follow-up, 56.4% of group i cases ...

Percutaneous Mitral Commissurotomy Rheumatic mitral stenosis continues to be endemic in developing countries, where mitral stenosis is the most frequent valve disease.1 Although the prevalence of rheumatic fever has greatly decreased in Western countries, it continues to represent an important clinical entity because of outmigration from developing countries. The figure given by the registry Eu...

Diagnostic and therapeutic problems commonly arise in patients with rheumatic heart disease despite the use of all available clinical data, including electrocardiographic and roentgenographic studies. The deficiencies of the conventional aids have become more apparent with attempts to define the physiological significance of mitral valve lesions. Since its introduction by Cournand and associate...

The movement of the anterior leaflet of the mitral valve has been recorded with an ultrasound echo technique. The intrinsic mobility of the valve cusps and the rate of ventricular filling are thought to influence the closure of the valve during diastole. Atrial contraction occurs at the end of ventricular diastole and reopens the valve before the mitral valve returns to the closed position befo...

OBJECTIVES To investigate the effects of transvalvar flow rate on aortic valve resistance and valve area after percutaneous transvenous balloon dilatation of the mitral valve in a homogeneous group of patients with rheumatic heart disease. DESIGN Retrospective analysis of 12 patients with combined aortic and mitral stenosis who had undergone balloon dilatation of the mitral valve over a perio...

Many studies of the pressures in the left atrium and the left ventricle of patients with mitral valve disease have been published. Initially obtained by direct puncture of the cardiac chambers at operation, such recordings have since been made possible by the development of techniques of left atrial puncture as a diagnostic procedure before operation. Direct determinations of the left atrial pr...

BACKGROUND Mitral stenosis, one of the grave consequences of rheumatic heart disease, was generally considered to take decades to evolve. However, several studies from the developing countries have shown that mitral stenosis follows a different course from that seen in the developed countries. This study reports the prevalence, severity and common complications of mitral stenosis in the first a...

A 44-year-old woman presented with dyspnea on exertion. Her past medical history included rheumatic heart disease and she had been followed up for rheumatic mitral valve stenosis for the last 4 years. Her symptoms had worsened over the 3 months prior to her presentation. She was evaluated in the emergency department and electrocardiographic examination revealed atrial fibrillation. Sinus rhythm...

Transcatheter aortic valve implantation (TAVI) has shown favorable outcomes in patients with severe symptomatic aortic valve stenosis who are at high surgical risk or are unsuitable candidates for open heart surgery. However, concerns exist over treating patients who have previously undergone mitral valve surgery due to the potential interference between the mitral prosthetic valve or ring and ...

CONGENITAL stenotic lesions of the mitral valve may be classified into various groups depending on the functional capacity of the left ventricle. In the extreme form, s8vere stenosis or atresia of the mitral valve is associated with hypoplasia of the left ventricle and aorta. Septal defects are usually present and these combinations are lethal in infaincy.i' 2 In the presence of a functioning l...
