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...

Congenital supravalvular mitral stenosis is a rare malformation characterized by the presence of a shelf-like fibrous membrane, with 1 or 2 small orifices, covering and obstructing the mitral valve. The membrane is positioned closely to the mitral valve (and sometimes it is attached to it); therefore, a preoperative diagnosis is inevitably difficult, even with the use of biplane echocardiograph...

The electrocardiograms in 32 patients with mitral valve disease have been compared with the pulmonary resistances, the pulmonary artery pressures, and the size of the mitral valve orifice. In patients with pure stenosis if the electrocardiogram showed the pattern of right ventricular hyper-trophy the total pulmonary resistance was usually 1000 dynes seconds cm.-5 or greater. If mitral insuffici...

BACKGROUND Percutaneous mitral commissurotomy (PMC) has become the procedure of choice for patients with isolated mitral stenosis. AIM To assess immediate and long-term results of PMC and identify predictors of event-free survival. METHODS Percutaneous mitral commissurotomy was attempted in 1380 patients (mean age 49.36+/-10.0 years) with severe mitral stenosis. RESULTS Good immediate res...

BACKGROUND Exertional dyspnoea is a limiting symptom in many patients with mitral stenosis but its causes remain incompletely understood. Ventilation during exercise is abnormal in chronic heart failure of all causes and there is increased ventilatory cost of carbon dioxide production. PATIENTS 23 patients with rheumatic mitral stenosis undergoing percutaneous balloon dilatation of the mitral...

Ventricular function during exercise in patients with mitral stenosis has not been widely studied. Accordingly, 20 patients with isolated mitral stenosis were assessed during supine, symptom-limited equilibrium radionuclide ventriculographic studies. All patients had a normal left ventricular (LV) ejection fraction at rest (greater than or equal to 50 percent), and all were in sinus rhythm. Lef...

Disseminated ossification of the lungs is rare. Most of the cases reported in. the literature are associated with mitral stenosis, hemosiderosis and granulomas. Wells and Dunlap,’ in a review of the literature in 1943, stated that about 45 cases of diffuse ossification of the lung unassociated with tuberculous scars had been reported, of which about 35 cases were of the racemose or branching ty...

BACKGROUND Increased plasma endothelin-1 concentrations have been observed in patients with rheumatic mitral stenosis. Endothelin-1 levels have never been investigated in patients with mitral stenosis and history of cerebral thromboembolism. METHODS We measured plasma concentrations of endothelin-1 in the peripheral venous blood samples obtained from 20 patients with moderate to severe rheuma...

We describe a 73 year-old patient with mitral valve pericardial bioprosthesis Carpentier-Edwards 29M implanted due to the rheumatic mitral stenosis 21 years ago. Hemodynamic destabilisation had emerged 18 months before the admission. Echocardiography revealed significant bioprosthesis degeneration with calcification of its leaflets, small pannus on the bioprosthetic ring, moderate mitral stenos...

ital, T tal, Te c aort A 53-year-old woman presented to our center with progressive fatigue and dyspnea on exertion (New York Heart Association functional class III). The patient’s medical history was significant for multiple cardiac interventions: open mitral commissurotomy for the treatment of rheumatic mitral stenosis 30 years earlier, mitral valve replacement for the treatment of severe mit...
