Two patients with biopsy-proven amyloid restrictive cardiomyopathy were presented. Both cases showed ventricularization of an elevated right atrial pressure wave form in absence of tricuspid regurgitation. Possible explanations for this finding as well as its clinical implications are discussed. This observation indicates that ventricularization of right atrial pressure wave form could be a useful hemodynamic sign in amyloid restrictive cardiomyopathy in absence of tricuspid regurgitation. Furthermore, such a finding does not seem to be specific for tricuspid regurgitation.
介绍了两名经活检证实为淀粉样蛋白限制性心肌病的患者。两例均显示在无三尖瓣反流的情况下右心房压力波形出现心室化。讨论了这一发现的可能解释及其临床意义。该观察结果表明，在无三尖瓣反流的淀粉样蛋白限制性心肌病中，右心房压力波形的心室化可能是一个有用的血流动力学征象。此外，这一发现似乎并非三尖瓣反流所特有。
