A total of 14 cases of infective endocarditis (IE) in children aged 6 months to 10 years were seen from December 1987 to December 1992 at the pediatric unit of Ayatollah Taleghani Medical Center. The majority of patients (12 of 14) were between 5 and 10 years of age. Acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. Or...

M itral valve stenosis of origin other than rheumatic fever is a rare entity. Giant-cell myocarditis is an extremely rare, with poor prognosis, probably autoimmune, granulomatous disease of the heart. Progressive congestive heart failure, intraventricular conduction defects and ventricular arrhythmias, which in many cases can be fatal, are the usual manifestations of this disease. On the contra...

The valvular disease usually involves two conditions: valvular stenosis and valvular insufficiency. Valvular stenosis occurs when a valve opening is smaller than normal due to stiff or fused leaflets. The narrowed opening may make the heart work very hard to pump blood through it. This can lead to heart failure. All four valves can be stenotic (hardened, restricting blood flow); the conditions ...

AIM While the incidence of rheumatic heart disease has declined dramatically over the last half-century, the number of valve surgeries has not changed. This study was undertaken to define the most common type of valvular heart disease requiring surgery today, and determine in-hospital surgical mortality and length-of-stay (LOS) for isolated aortic or mitral valve surgery in a United States tert...

The genetic mucopolysaccharidosis syndromes (MPS) are autosomal recessive inborn errors of metabolism. Heart valve involvement in MPS is not uncommon but only a few case reports of successful cardiac surgery are available. In particular, reports of combined aortic and mitral stenosis associated with MPS type I-S are very rare. Both type I and type VI MPS are associated with significant left sid...

It is known that rheumatic heart disease frequently results in isolated mitral regurgitation without concomitant mitral stenosis, especially in countries with a high prevalence of rheumatic fever. However, more recent surgical pathologic data also have demonstrated a high incidence of mitral valve prolapse in cases of rheumatic heart disease, which suggests that rheumatic fever may be a cause o...

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...
