Early cardiac doppler findings and venous hemodynamic burden after combined superficial venous treatment for primary lower extremity varicose veins: an exploratory retrospective cohort study.

In the overall paired analysis, postoperative decreases in tricuspid E-wave velocity, tricuspid E/e′ and an increase in tricuspid systolic annular velocity were nominally significant (raw P = 0.048, 0.027 and 0.031), but these findings did not remain significant after within-table FDR correction (adjusted P = 0.288, 0.279 and 0.279, respectively).
