The Correlation Analysis of Tricuspid Regurgitant Volume, Tricuspid Regurgitant Fraction, and Indexed Right Ventricular End-Diastolic Volume Across Transthoracic Echocardiography-Based Tricuspid Regurgitant Severity Grades
Correlation between (A) TR volume (mL) and TR fraction (%); (B) RVEDV indexed by BSA (mL/m2) and TR volume; (C) indexed RVEDV and TR volume; (D) indexed RVEDV and TR fraction in patients with moderate or less, moderate-severe, and severe or higher TR grades according to TTE. BSA = body surface area; RVEDV = right ventricular end-diastolic volume; TR = tricuspid regurgitation; TTE = transthoracic echocardiography.
