Abstract:
To clarify the characteristics of the jugular venous pulse and its genesis in Ebstein's anomaly, 6 patients with Ebstein's anomaly whose mean age was 45 +/- 9 years, and 10 normal subjects with a mean age of 27 +/- 6 years were studied by phono-mechanocardiography and echocardiography. The parameters included the relative height of the jugular c wave, the relative timing of the upstroke (Q-Cu interval) and the peak of the jugular c wave (Q-Cpeak interval), the relative timing of the upstroke of the carotid artery pulse, the relative timing of tricuspid valve closure (Q-Tc interval), the excursion of the closing motion of the anterior tricuspid leaflet (TV excursion), the distance between the anterior mitral annulus and the septal tricuspid annulus (M-T distance), the area of atrialized right ventricle (ARV area) and the maximum area of the tricuspid regurgitant signal. Among 6 patients with Ebstein's anomaly, tricuspid regurgitation was predominant in 4 and mild in the remaining 2. The results were as follows: 1. A large jugular c wave was observed in 4 of the 6 patients. Two patients with large ARV area had giant c wave. 2. The interval of the upstroke of the carotid artery pulse and that of the jugular c wave was about 39.2 msec. 3. The Q-Tc interval was significantly longer and the TV excursion was significantly greater in the patients than in the normal controls. 4. There was only a weak positive correlation between the Q-Cpeak interval and the Q-Tc interval. No significant correlation was observed between the relative height of the jugular c wave and the TV excursion. 5. There was a positive correlation between the relative height of the jugular c wave, the ARV area and M-T distance. 6. No obvious correlation was observed between the grade of tricuspid regurgitation and the relative height of the jugular c wave. These results suggest that augmentation of the c wave of the jugular venous pulse is characteristic of Ebstein's anomaly and that it correlates closely with the severity of displacement of the tricuspid valve and the size of the atrialized right ventricle.
