缩窄性心包炎二种少见的超声表现及临床意义
Two types of rareechocardiographic manifestation in the patients with constrictive pericarditis and its clinical significance
【摘要】 目的分析缩窄性心包炎(CP)二种少见的超声表现及临床意义。方法1981-04-2004-04回顾分析广东省心血管病研究所187例CP患者的超声资料。重点观察左室射血分数(LVEF)及吸气相二尖瓣E峰(VEi)较呼气相(VEe)的下降率VER=(VEe-VEi)/VEe。结果大部分病人符合CP一般超声改变。但发现二种少见的超声征象。(1)14例(7.49%)CP患者LVEF<0.50(0.45±0.42)。心包钙化明显甚或嵌入心肌。(2)48例窦性心律CP患者行多普勒超声检查,10例(20.83%)VER<25%(均值14.84%)并见心包广泛粘连、挛缩、大片缩窄环形成。结论CP患者LVEF下降及二尖辩血流速度吸气相较呼气相下降<25%时,提示心包病变严重。范围广泛,应引起临床高度重视。
【Abstract】 Objective To evaluate the unusual echocardiographic manifestation and its clinical value in the patients with constrictive pericarditis (CP). Methods To analyse the echocardiographic manifestation of CP in 187 patients retrospectively, especially left ventricular ejection fraction (LVEF) and variation with respiration (VER) in mitral E velocity. Results Most of the patients with CP expressed the common echocardiographic features of CP. But some unusual echocardiographic signs were revealed. (1)LVEF<0.50 occurred in 14 patients with CP and pericardial tissue showed obvious calcification or mixed together with myocardium. (2)Doppler echocardiographic study was performed in 48 patients with CP in sinus rhythm. In 10 patients (20.80%) there existed VER<25% ,extensively thick scar restricted cardiac filling by bandlike constriction and total or near-total obliteration of the pericardial space. Conclusion LVEF< 0.50 and VER <25% in the patients with CP suggest that the pericardial damage may be serious and extensive.
