We report four cases of patients with documented constrictive pericarditis who had evidence of reduced right ventricular (RV) systolic function. Assessment of RV systolic function was performed by pulsed tissue Doppler sampling of basal RV free wall velocity at the level of the tricuspid annulus in the four-chamber view. Velocity values and time velocity integral calculated from the velocity envelope were compared with values from controls. All four patients had evidence of epicardial RV injury at the time of pericardiectomy and persistent symptoms and RV systolic dysfunction after pericardiectomy.
我们报告了4例有缩窄性心包炎记录且存在右心室(RV)收缩功能降低证据的患者。通过在四腔视图中经三尖瓣环水平对RV游离壁基底速度进行脉冲组织多普勒采样来评估RV收缩功能。将从速度包络计算得到的速度值和时间速度积分与对照组的值进行比较。所有4例患者在心包切除术时均有RV心外膜损伤的证据,心包切除术后仍有持续症状和RV收缩功能障碍。
