Study population consisted of 10 patients with mitral stenosis and sinus rhythm (MS-SR), 15 with MS and Af (MS-Af), 15 with mitral valve replacement and Af (MVR-Af), 10 with Af without organic heart disease (lone-Af) and 15 normal subjects. Various parameters, including peak velocities of C and S waves, closing amplitude of anterior mitral valve echogram during end-diastole, amplitude of the mitral annulus and interatrial septal motion during systole and left atrial pressure during the mitral closing period or end-diastole, were measured in each group. Results were as follows: 1. C wave was observed in all Af groups and six of 10 patients with MS-SR. Particularly, peak velocity of the C wave in MS-Af group was increased significantly compared with those of every other group. 2. Peak velocity of S wave in all Af groups, particularly in MS- and MVR-Af groups, decreased significantly compared with that of the normal group. 3. There were significant negative correlations between preceding R-R interval and peak velocity of the C wave or closing amplitude of anterior mitral valve echogram or left atrial pressure during end-diastole in MS-Af group. 4. There were significant positive correlations between preceding R-R interval and peak velocity of the S wave or amplitude of the mitral annulus or interatrial septal motion during systole in MS-Af group. 5. Peak velocities of the C and S waves had no correlations to preceding R-R interval in lone-Af group. We concluded that the C and S waves of pulmonary venous flow velocity pattern in MS-Af are affected by cycle length, and that the former is influenced by left atrial pressure and/or pliability of the mitral valve during the mitral closing period, and the latter by the grade of left atrial dilatation and/or preceding left atrial emptying.</p>","PeriodicalId":77193,"journal":{"name":"Journal of cardiology.

Physical examination on admission revealed blood pressure of 98/62 mmHg, pulse rate 96 per min, temperature 37.7 degrees C and respiration 35 per min.

Organic changes of the aortic valve were assessed by two-dimensional echocardiography, and aortic regurgitation was assessed by color Doppler flow imaging. Twenty-two normal subjects (normal group) and 17 patients with essential hypertension (hypertensive group) served as controls. Mean ages were matched among the three groups. 1. Left ventricular dilatation (seven patients) and hypertension (six patients) were the dominant part of underlying disease in the musical group. 2. Musical S2 was classified in the following two types based on the phonocardiographic characteristics; musical vibrations followed immediately after the accentuated S2, and the S2 which was replaced by regular vibratory waves. 3. Frequency of the musical vibrations ranged from 120 to 200 Hz, and its duration ranged from 60 to 120 msec. Amplitude of the musical vibrations decreased by inhalation of amyl nitrite, but increased by infusion of methoxamine. In a case with mild rheumatic valve disease, methoxamine induced marked intensification of the amplitude and prolongation of the duration of the musical vibrations, finally giving a typical cooing murmur. 4. Echo intensity of the aortic valve tended to be higher in the musical group than in the other two groups. 5. Echocardiographically, aortic regurgitation appeared more frequently in the musical group (88%) than in the normal (36%) and hypertensive (41%) groups. Area of the aortic regurgitant signal was significantly larger in the musical group (4.1 +/- 1.4 cm2) than in the normal (1.2 +/- 0.8 cm2) and hypertensive (2.3 +/- 1.2 cm2) groups. 6.

Intraoperative transesophageal echocardiography is now used to monitor left ventricular function and to confirm the result of surgical correction immediately after cardiac operation. In this study, we evaluated the detectability of air embolism and the effect of hemodynamic changes on physiological mitral regurgitant flow by transesophageal Doppler echocardiography (TEDE). TEDE was more sensitive than precordial Doppler ultrasound in detecting intracardiac air. TEDE could detect air inflow to the right atrium earlier than alterations in pulmonary hemodynamics. The monitoring of intracardiac air by TEDE minimized the complication by air embolism. Regarding physiological mitral regurgitation, the degree of regurgitation increased with the elevation of BP in 70% of patients. An increase in afterload seemed to cause accidental volume loading on the left heart resulting in physiological mitral regurgitation. Intraoperative monitoring of regurgitant flow by TEDE was useful for the anesthesiologist as a guide of hemodynamic management. Transesophageal echocardiography is a useful intraoperative monitoring method regardless of its several disadvantages.

{"title":"[Pathology of the cardiac valves].","authors":"R Okada","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The cardiac valves develop from the endocardial cushions of the fetus. Some congenital anomalies such as the 21-trisomy syndrome (Down syndrome) show poorly differentiated immature valves similar to those under development. The normally mature valves have four layers of the connective tissue, i.e., proximalis, spongiosa, fibrosa and distalis. Gargoylism promotes abnormal thickening of collagen fibers in the fibrosa via acid-mucopolysaccharide (aMPS) overproduction, but Marfan syndrome weakens the valves in spite of increased aMPS. The reversed conditions could be caused by the difference of increased aMPS; i.e., dermatan sulfate B or heparitin sulfate in gargoylism, on the contrary, dermatan sulfate A and C or hyaluronic acid in Marfan syndrome. Hemodynamic changes in the valves consist of diffuse hypertrophy of the proximalis and fibrosa in high flow cases and focal thickening of the proximalis at the line of closure and of the spongiosa at the anatomical edge in high pressure cases. Aging of the valves simulates partly the hemodynamic changes but degeneration of collagen fibers in the fibrosa after consumption of the spongiosa is more prominent than the latter. So-called myxomatous degeneration in the mitral valve prolapse cases seems reactive hypertrophy of the spongiosa replacing the interrupted fibrosa. Spontaneous chordal rupture is partly related to myxomatous change, but that in the elderly cases shows only simple disruption of collagen fibers with loss of the spongiosa tissue. Calcification of the valvular rings and bodies often observed in the elderly cases with parallelism to degeneration of the connective tissue produces mitral regurgitation, aortic stenosis or both, showing a preponderance of females.(ABSTRACT TRUNCATED AT 250 WORDS)</p>","PeriodicalId":77193,"journal":{"name":"Journal of cardiology.

In this study, the effects of the depth between transducer and jet flow on color Doppler flow imaging were evaluated with the transesophageal (3.75 MHz) and conventional (2.5 MHz) transducers by using a flow phantom. A flow circuit was filled with saline in which nylon corpuscles (average diameter; 5 microns) were suspended to enhance the Doppler effects. A turbulent jet with constant flow velocity (Reynolds number; 3500) stimulating valvular regurgitant flow was produced in a water bath through a small orifice (2 mm) by constant driving pressure (100 mmHg). Color jet imaging in the long- and short-axis views were observed at each depth with both transducers. The measurement was made every 1 cm in depth from 3 to 12 cm. The color gain setting was fixed at the optimal point so as to get the maximal flow image with the minimal static background noise. We obtained larger image of the color jet signal with the conventional than the transesophageal transducer. Although a mosaic pattern was displayed more distinctly with the transesophageal transducer compared with that of the conventional transducer, the transesophageal image tended to become indistinct in the depth deeper than 8 cm.
