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...

acute fulminant myocarditis is a life-threatening inflammatory disease of the myocardium characterized by the rapid deterioration of the hemodynamic status of the affected individual. with prompt recognition and appropriate management, complete recovery of ventricular function is likely within a few weeks. we introduce a 28-year-old man with acute fulminant myocarditis, who experienced circulat...

IN 21 INFANTS, each with symptomatic congenital aortic stenosis and left ventricular cavity of nearly normal size studied clinically,' evidence for mitral insuffiiegncy was frequently encountered. In five of the patients left ventriculography was done and, in each, mitral insufficiency was demonstrated. This background of experience led us to study, in particular, the mitral valve in specimens ...

A four month old infant was investigated for heart failure was found to have mitral incompetence and severe subvalvar aortic stenosis. The left ventricular outflow tract obstruction was found to be due to an anatomically anomalous mitral valve. The obstruction could only be relieved by removal of the mitral valve and its replacement with a St Jude's prosthesis. Two years after operation the chi...

Many problems and complications associated with heart valves are related to the dynamic behavior of the valve and the resultant unsteady flow patterns. An accurate depiction of the spatial and temporal velocity and rms distributions imparts better understanding of flow related valve complications, and may be used as a guideline in valve design. While the generalized correlation between increase...

percent had systemic emboli. Conclusions from this large series were: 1) atrial fibrillation is the main cause of systemic embolism; 2) embolism is as common with mitral regurgitation as with mitral stenosis; 3) mitral valve calcification predisposes to operative emboli; 4 ) atrial appendage size has no influence on the occurrence of systemic embolism. Review of the literature has not revealed ...

f all valve lesions, mitral stenosis has the most options for ntervention and in many ways is the valve lesion where it is asiest to make a decision that intervention is necessary. his was the first acquired valve lesion where patient ymptoms and ultimate prognosis could be improved surgially even before cardiopulmonary bypass was available. The ndications for the timing of valve repair or repl...

Tamer Tetiker, Department of Internal Medicine, Medical Faculty, Çukurova University, TR-Adana (Turkey) Dear Sir, Although amyloidosis secondary to collagen vascular diseases, in particular to Beh-çet’s disease [1], is frequently reported, rheumatic heart disease with amyloidosis is rare. Herein, we report a patient with mitral valve stenosis due to rheumatic heart disease and renal amyloidosis...

In complex, data-based prediction problems, such as medical diagnosis, the Elman Neural Net (ENN) has been applied for the automated detection of various diseases, such as mitral valve stenosis. This paper discusses the design and implementation of an automated classification system for heart diseases, based on ultrasonic devices. M-mode class images are applied to classify the degree of stenos...

The mean pressure drop across the mitral valve and atrioventricular pressure half-time were measured noninvasively by Doppler ultrasound in 40 normal subjects, in 17 patients with mitral regurgitation, 32 patients with mitral stenosis and 12 with combined stenosis and regurgitation. In normal subjects pressure half-times were 20--60 msec, in patients with isolated mitral regurgitation 35--80 ms...
