Congenital cardiac diseases included 30 patients with tetralogy of Fallot, 20 with ventricular septal defect, nine with atrial septal defect, and eight with pulmonary stenosis. Group B (35 cases); preoperative state of transposition of the great arteries. Group C (43 cases); post-operative state of congenital cardiac disease whose pre-operative right ventricular systolic pressures represented more than 70% of the left ventricular systolic pressures. This group included 31 patients with tetralogy of Fallot, seven with ventricular septal defect, four with atrial septal defect and one with patent ductus arteriosus. Group D (21 cases); post-operative state of transposition of the great arteries. Fifteen min after intravenous infusion of 30-50 microCi/kg 201-TlCl, myocardial images were obtained in five projections (anterior, LAO 30 degrees, 45 degrees, 60 degrees, and lateral). The angles were determined to demonstrate clearly the interventricular septum and the ventricular free wall. The images of end-diastolic phase were obtained using the ECG-synchronized gated method in each projection. The region of interest (ROI) was defined as a section or slice by drawing two lines perpendicular to the septum, and the counts of the systemic and pulmonic ventricular free wall (Cs and Cp) were analyzed to evaluate the pressure of the pulmonic ventricle.

Twenty-five patients with posterior mitral valve prolapse who underwent mitral valve replacement were studied. They were categorized in three groups; 14 patients with MR due to ruptured chordae tendineae (RCT) of the posterior leaflet (RCT group); three patients with looping of the chordae tendineae in the middle scallop of the posterior leaflet (looping group); and eight patients with both RCT and looping (looping + RCT group). It was difficult to distinguish the looping group from the other two groups by their 2D echocardiographic findings, which were characteristic of those of RCT. However, the following findings were more frequently encountered in the patients with looping than in those without: 1) aberrant or absent systolic coaptation with salient arc of the posterior leaflet, observed in six of the RCT group (43%), two in the looping group (67%) and seven in the looping + RCT group (88%); 2) with thickened edges of the posterior leaflet, shown in three of the RCT group (21%), two of the looping group (67%) and five of the looping + RCT group (63%) in the long-axis view, and also noticed in four of the RCT group (29%), two of the looping group (67%) and six of the looping + RCT group (75%) in the short-axis view. In the clinical history, the onset of a heart murmur, congestive heart failure and surgical treatment occurred at significantly younger ages in the looping group than in the RCT group. As for hemodynamic parameters, pulmonary hypertension was significantly milder in the looping group than in the RCT group. In conclusion, although 2D echocardiographic findings of patients with looping were similar to those of patients with RCT, it seemed possible to differentiate the looping group from the RCT group by the 2D finding of a prolapsed posterior mitral valve with a salient arc and a thickened edge.

Three types of frequency spectral pattern of mitral regurgitation (MR) were demonstrated: A) broad, spanning 100 to 500 Hz, B) narrow, characterized by one giant peak, and C) two peaks. The reason for these patterns was not clear, but they may be related to various hemodynamic events. 2. The mean frequency (f) in MR was 295 +/- 38 Hz and it increased in proportion to the regurgitant grade: e.g., Sellers II, 258 +/- 27 Hz; Sellers III, 294 +/- 23 Hz; and Sellers IV, 311 +/- 65 Hz. The accumulated percentage of the 200-400 Hz component decreased, while that of the 400-600 Hz component increased. 3. The f in MR of various etiologies were as follows: It was higher in ruptured chordae tendineae, rheumatic cases and mitral valve prolapse syndrome, but was lower in papillary muscle dysfunction and dilated cardiomyopathy. In the latter two, the percentage of the 0-200 Hz component was greater than in other disorders. The degree of left ventricular dysfunction and of myocardial injury may be responsible for the changes in the propagation properties. In ventricular septal defect and aortic stenosis, the f was 306 +/- 12 Hz and 230 +/- 40 Hz, respectively. The frequency spectrum of the latter was lower than that of MR, which may be derived from the difference between ejection and regurgitant murmurs; whereas, that of ventricular septal defect was similar to that of rheumatic MR. 4. The relation between the frequency spectrum and the phase of systole was studied. In dilated cardiomyopathy and papillary muscle dysfunction, the f of each phase increased in late systole; whereas, the maximum f was in mid-systole in other disorders. 5. Administration of amyl nitrite resulted in a decreased f, an increased percentage of the 0-200 Hz component, and a decreased 400-600 Hz component. The spectral distribution shifted to the lower frequency region.

An experiment was performed to obtain Doppler signals from the surface of a vibrating tonometer at a frequency of 128 Hz. When the CD stripe was obtained, a similar FFT stripe was also recorded from the same sampling site. Fourteen patients with musical murmurs were selected from 2,000 consecutive phonocardiographic records made during the last one and a half years. The CD stripe was obtained in three and the FFT stripe in six. When both stripes were obtained, the FFT stripe was always obtained if we set carefully the sample site in the CD stripe, and these two were consistent in timing. We concluded that, in view of the close correlation between the CD stripe and the FFT stripe, the newly observed CD stripe is also a characteristic finding reflecting a regularly vibrating structure.

To assess the diagnostic value of each collapse component in identifying cardiac tamponade, two-dimensional and M-mode echocardiograms were recorded simultaneously with the measurement of intrapericardial pressure in five patients as they underwent pericardiocentesis. Before pericardiocentesis, each patient had evidence of right ventricular and right atrial collapse. In addition, left atrial collapse was observed in four patients. During pericardiocentesis, left atrial collapse initially resolved accompanied by a drop in pressure in the pericardial sac. Continuous drainage of pericardial effusion resulted in significant symptomatic improvement and the cessation of paradoxical pulse at the point of resolution of right ventricular collapse. However, right atrial collapse persisted after resolution of right ventricular collapse, but it was absent when pericardiocentesis was completed. Injection of saline solution with heparin into the pericardial sac for cleansing initially caused right atrial collapse, while right ventricular collapse developed with the appearance of cardiac tamponade. In one patient, the simultaneous recording of right ventricular and intrapericardial pressures and two-dimensional echocardiograms demonstrated that right ventricular collapse occurred early in diastole, when intrapericardial pressure exceeded right ventricular pressure. In conclusion, right ventricular collapse is the most reliable sign of cardiac tamponade. Right atrial collapse occurs in the early stage of cardiac tamponade.
