23 patients with common atrioventricular canal were studied, seven with associated pulmonary stenosis, using methods of quantitative angiocardiographie (ventricular volume, ejection fraction, wall motion, Emas as an index of contractility). Left and right ventricular end-diastolic volume is increased and related to the Qp/Qs ratio. Pulmonary stenosis has limitant effect on end-diastolic volume, likely by variations of right ventricular compliance. Ejection fraction tended to normal values or is lightly reduced, but the study of wall motion demonstrated a severe hypokinesis of diaphraguscolar septum and of the diaphragmatic region; also the contractility is depressed. Finally were reported some observations about the haemodynamics behaviour of the common atrioventricular canal in the early post-surgical stage.
对23例共同房室通道患者进行了研究,其中7例伴有肺动脉狭窄,采用定量心血管造影方法(心室容积、射血分数、壁运动,Emas作为收缩性指标)。左、右心室舒张末期容积增加,且与肺循环血流量/体循环血流量比值相关。肺动脉狭窄对舒张末期容积有限制作用,可能是由于右心室顺应性的变化。射血分数趋于正常或略有降低,但壁运动研究显示膈肌隔区和膈肌区域严重运动减弱;收缩性也降低。最后报告了关于共同房室通道术后早期血流动力学行为的一些观察结果。
