tricuspid annular plane systolic excursion is correlated with poor outcome in surgery for rheumatic heart valvular disease

Background: right ventricular (rv) function is a major determinant of clinical outcome, butits function indices have not been studied well in surgery for rheumatic valvular heart disease.the aim of this study was to determine the correlation of tricuspid annular plane systolicexcursion (tapse) with outcome of rheumatic heart valve surgery.methods: a prospective comparative study was conducted including 100 eligible patients whowere divided into two groups based on rv function as assessed by tapse measured by twodimensional(2d) echocardiography preoperatively. those with tapse less than 15 mm wereincluded in group 1 and those with tapse of 15 or more were included in group 2.results: 50 patients were included in group 1 and 50 patients in group 2. mean age of thepatients was 56.78 ± 15.21 years in group 1 and 54.46 ± 15.03 years in group 2 (p = 0.444). 34(34%) patients underwent aortic valve replacement (avr), 35 (35%) underwent both aortic andmitral valves replacement, and 31 (31%) ones had mitral valve replacement (mvr). a significantdifference was found between the duration of ventilation (5.15 ± 2.80 hours in group 1 vs.3.72 ± 2.71 hours in group 2, p = 0.001), postoperative inotropic requirement [more than24 hours in 18 (36%) patients in group 1 vs. 7 (14%) patients in group 2, p = 0.003], totalintensive care unit (icu) stay (8.92 ± 3.62 days in group 1 vs. 5.20 ± 2.06 days in group 2,p = 0.001), and mortality [7 (14%) in group 1 vs. 2 (4%) in group 2, p = 0.038].conclusion: tapse less than 15 mm in patients undergoing surgical correction for rheumaticvalvular heart disease leads to poor outcomes. these patients need special attention perioperatively.
