چکیده
OBJECTIVES The primary objective of this study was to establish the relationship among tricuspid annular velocity (S'), tricuspid annular plane systolic excursion (TAPSE), and stroke volume (SV) in a cardiac surgical population with and without right ventricular (RV) dysfunction. The secondary objective was to assess the effect of ephedrine on these relationships in a population without RV dysfunction. DESIGN Prospective, nonrandomized, unblinded study. SETTING Single tertiary-level, university-affiliated hospital. PARTICIPANTS Twenty-seven patients undergoing elective coronary artery bypass grafting with no evidence of RV dysfunction (Group 1). Sixteen ventilated postcardiac surgical patients with suspected RV dysfunction (Group 2). INTERVENTIONS Ten mg of intravenous ephedrine to Group 1 only. MEASUREMENTS AND MAIN RESULTS Using transthoracic echocardiography, S' and TAPSE were measured using color tissue Doppler applied at the RV base in a 4-chamber view. SV was calculated using thermodilution. Six patients in Group 1 and 6 patients in Group 2 were excluded because of poor imaging or ineligibility. Modest correlation was found between TAPSE and SV in Group 1 (R = 0.50, p<0.001). There was no correlation between TAPSE and SV in Group 2. There was no correlation between S' and SV in both groups. In Group 1, the relationship between TAPSE and S' was curvilinear (R = 0.74 pre-ephedrine, p<0.001; R = 0.64, p = 0.009 post-ephedrine). There was no relationship between TAPSE and S' in Group 2. Ephedrine increased S' and TAPSE. The TAPSE-S' relationship was not significantly altered. CONCLUSIONS In the presence of RV dysfunction, TAPSE did not correlate with cardiac output. In the absence of RV dysfunction, the relationship between TAPSE and S' described a curvilinear relationship.

BACKGROUND Longer survival after the total repair of the Tetralogy of Fallot increases the importance of late complications such as right ventricular dysfunction. This is a prospective study of the right ventricular function in totally corrected Tetralogy of Fallot patients versus healthy children.

Introduction Right ventricular ejection fraction (RVEF) is an important predictor of outcome in heart failure patients. Although cardiac magnetic resonance (CMR) assessment of RV function is considered gold standard and echocardiographic measurement of RVEF is challenging due to its unique geometry; CMR still has limited availability in the wider community. Therefore alternative echocardiograph...

AIMS Previous studies have demonstrated that the radionuclide right ventricular (RV) ejection fraction (RVEF), tricuspid annular plane systolic excursion (TAPSE), and tissue Doppler peak systolic tricuspid annular velocity (STr) were independent predictors of cardiac survival in stable patients with left ventricular systolic dysfunction (LVSD). No study has compared the prognostic value of thes...

Objective: To assess right ventricular systolic function using indices derived from tricuspid annular motion, and to compare the results with right ventricular ejection fraction (RVEF) calculated from radionuclide angiography. Design: Pulsed Doppler echocardiography indices were obtained from 10 patients with a normal RVEF (group 1) and from 20 patients whose RVEF was less than 45% (group 2). R...
