| Popis: | 1. 1. Results of left heart catheterization in two normal individuals and 125 patients with rheumatic heart disease are presented. 2. 2. The normal pressure curves are described. No pressure gradients exist across a normal mitral or aortic valve. 3. 3. Characteristic findings of mitral stenosis are: (a) ventricular filling pressure gradient usually present throughout diastole, (b) giant “a” waves in the left atrial pressure tracing. 4. 4. Ventricularization of the left atrial pressure curve may occur in mitral regurgitation. A pressure gradient may be present, but unlike mitral stenosis, is found only early in diastole. A characteristic pressure tracing is obtained as the catheter is whipped back from ventricle to atrium within a single cardiac cycle. 5. 5. Aortic stenosis is characteristically accompanied by a systolic pressure gradient across the aortic valve. Giant “a” waves are observed in the left atrial pressure tracing. The end-diastolic pressure in the left ventricle is generally elevated. Possible causes for this are discussed. |
