Carrying out a mitral valve replacement (MVR) while preserving all chordae tendineae in patients with mitral regurgitation has been proven beneficial to the left ventricular performance. To evaluate the effectiveness of this technique in patients with mitral stenosis, a comparison of the echocardiographic data between patients who were operated on using this technique (Group Preservation = Grou...

Severe hypertension was seen in a patient with mitral stenosis when in sinus rhythm. A large fall in systolic blood pressure and in left ventricular end-diastolic pressure was caused by ventricular pacing. Contrary to the usual situation in mitral stenosis this patient paradoxically is a subject who improved haemodynamically with the loss of sinus rhythm and of atrial systole.

BACKGROUND Severe mitral stenosis is usually symptomatic and is treated by BMV or surgery, whereas mild to moderate mitral stenosis is usually asymptomatic or mildly symptomatic and managed medically. Patients in the later group may become symptomatic during episodes of exercise and increased heart rate. Beta-blockers are frequently used in patients with mitral stenosis to control the heart rat...

The cardiac output has been measured during the immediate post-Valsalva maneuver recovery period in normal subjects, patients with clinically significant mitral stenosis, and patients with alterations of the autonomic nervous system. When compared with the resting value, it was found that normal subjects had a decrease in cardiac output during the immediate post-Valsalva recovery period, while ...

OBJECTIVE To evaluate the cardiovascular findings and clinical follow-up of patients with Williams-Beuren syndrome. METHODS We studied 20 patients (11 males, mean age at diagnosis: 5.9 years old), assessed for cardiovascular abnormalities with electrocardiography and Doppler echocardiography. Fluorescence in situ hybridization (FISH) was used to confirm the diagnosis of the syndrome. RESULT...

surgery and to enhance our understanding of the pathophysiology of mitral stenosis. Although surgery produced a significant increase in calculated mitral valve area, the degree of improvement varied markedly. The younger patients had the greater increase in mitral valve area. The change in cardiac index and pulmonary vascular resistance correlated well with the change in mitral valve area. Only...

Balloon mitral valvuloplasty has, over the last 15 years, become an established interventional procedure. For patients with pliable uncalcified mitral stenosis, dilatation with the Inoue balloon is the intervention of choice, oVering results comparable to surgical commissurotomy. In the Western world, however, with the gradual extinction of rheumatic fever, patients with mitral stenosis are now...

BACKGROUND Infective endocarditis rarely causes mitral valve stenosis. When present, it has the potential to cause severe hemodynamic decompensation and death. There are only 15 reported cases in the literature of mitral prosthetic valve bacterial endocarditis causing stenosis by obstruction. This case is even more unusual due to the mechanism by which functional mitral stenosis occurred. CAS...

OBJECTIVES This study investigated the hemostatic status of the right and left atria in patients with mitral stenosis. BACKGROUND Systemic thromboembolism is a serious major complication in patients with mitral stenosis. However, the pathogenesis of thromboembolism in mitral stenosis is not fully understood. METHODS We determined the plasma levels of biochemical markers for platelet activit...

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...
