"Malignant" mitral stenosis

Symptomatic mitral stenosis caused by a left atrial mass as the first sign of metastasis of a malignant tumor is extremely rare and frequently associated with poor prognosis. We report a case of a 59-year-old man with a history of grade 3 malignant fibrous histiocytoma on his left tigh treated by limb-sparing surgery 17 months earlier, who was admitted with 10-days of worsening dyspnea. Imaging...

MITRAL STENOSIS COMPLICATED BY RENAL ARTERY EMBOLISM

Six patients with mitral stenosis complicated by renal artery embolism studied prospectively are presented. In five patients there was unilateral and in one patient bilateral renal artery involvement. The diagnosis was confirmed by intravenous pyelography, retrograde pyelography, renal angiography, renal scan or a combination of these. All had atrial fibrillation, proteinuria and elevated ...

Phonocardiography is-often more valuable than electrocardiography in timing mechanical events in the cardiac cycle. This study shows that the opening and closing of the mitral valve are related to the length of the previous heart cycle as demonstrated by the variations occuring in aluricular fibrillation. These variations in valve action are controlled by the pressure gradient between left auri...

8. What is the pathophysiology of mitral stenosis? Increased left atrial pressure is necessary to push blood through a stenotic mitral valve from the left atrium into the left ventricle. Increased left atrial pressure is transmitted retrograde into the pulmonary veins and pulmonary capillaries and ultimately into the pulmonary arteries. It gives the patient a sensation of dyspnea. A left atrial...
