Lung biopsy in mitral stenosis.
The recent development of intrathoracic operations upon patients with mitral stenosis has provided an opportunity to study by biopsy the changes in the hearts and lungs of these patients at a time when, although the disease is fully established, the general condition is still good. Since, in addition, the specimens are fixed immediately, all suspicion that the appearances seen are terminal or a...
متن کاملEvaluation of the severity of mitral stenosis and regurgitation.
Indices have been developed that provide an improved means for evaluation of the degrees of severity of mitral stenosis and regurgitation. The severity of anatomic mitral valve disease found at surgery or autopsy was considered to be the determinant of the state of the valve. An index of the time for the diastolic atrioventricular pressure gradient to fall to half its value multiplied by 100 an...
متن کاملMITRAL 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 ...
متن کاملCardiac function in experimental mitral stenosis.
The results of S5 combined right and left heart catheterizations in normal dogs and dogs with experimental mitral stenosis are presented. Animals lived as long as 10 months with elevated pulmonary vein pressures. Pulmonary vein pressures in excess of 15 mm. Hg were associated with mitral orifice areas which were smaller than those found in normal animals. Elevation of pulmonary vein pressure wa...
متن کاملLeft ventricular function in rheumatic mitral stenosis.
Haemodynamic factors contributing to clinical disability in patients with rheumatic mitral stenosis have been under discussion and investigation for decades. Prior to the development of left heart catheterization, a low cardiac output in the presence of little or no pulmonary hypertension was taken as evidence for a myocardial 'insufficiency'. With the use of left heart catheterization, it was ...
