摘要
Abstract
Objective To demonstrate the possibility when discriminating between severe and nonsevere tricuspid regurgitation by E-wave velocity in tricuspid flow.Methods The peak velocity of the tricuspid inflow E-wave was measured in 107 patients,who were divided into mild group(n =39),moderate group(n =42)and severe group(n =26)according to the degree of tricuspid regurgitation(TR).Results Peak E-wave velocity of mild group,moderate group and severe group was (48.6 ±13.8)cm/s,(47.4 ±11.7)cm/s,and (78.3 ±26.1)cm/s, respectively.Mean E-wave velocity of mild group and moderate group were similar,which were lower than that of severe group (P <0.01).A peak E-wave velocity of over 62 cm/s had a sensitivity of 71% and specificity of 92% for the detection of severe TR.Conclusion Increased peak tricuspid E-wave velocity is associated with severe TR and thus can be used as a simple measure of TR grade.关键词
