The echocardiographic and haemodynamic findings with a patient with hypertrophic obstructive cardiomyopathy (HOCM) and dynamic subpulmonary stenosis, without left ventricular gradient, are described. The echocardiogram shows not only asymmetric septal hypertrophy, systolic anterior movement of the anterior mitral leaflet, and midsystolic collapse of the aortic valve, but also increase in the right ventricular wall echoes and systolic collapse of the pulmonary valve. We believe that in the absence of pulmonary hypertension these signs, particularly the systolic closing movement of the pulmonary valve cusp, may suggest right ventricular obstruction in HOCM.
本文描述了一名患有肥厚型梗阻性心肌病(HOCM)和动态性肺动脉瓣下狭窄且无左心室压力阶差的患者的超声心动图和血流动力学表现。超声心动图不仅显示出不对称性室间隔肥厚、二尖瓣前叶收缩期前向运动以及主动脉瓣中期收缩期关闭,还显示右心室壁回声增强和肺动脉瓣收缩期关闭。我们认为,在无肺动脉高压的情况下,这些征象,尤其是肺动脉瓣叶的收缩期关闭运动,可能提示HOCM患者存在右心室梗阻。
