Abstract
- Background Despite successful repair of aortic coarctation (AoC), changes in the left ventricular (LV) regional myocardial function are reported. The aim of this study was to assess the left ventricular systolic function in patients after the successful repair of aortic coarctation using tissue Doppler imaging (TDI) according to the age of aortic coarctation repair. Methods 31 patients (mean age, 12.0 +/− 4.2 years) followed up after a successful chirurgical repair of aortic coarctation (mean follow up, 8,6 ± 7,6 years) were studied by echocardiography. The study population was divided in two groups: patients repaired at age 2 years (Group 1, n = 17) and patients repaired at age > 2 years (group 2, n = 14). The TDI parameters and the conventional echocardiographic indices of the left ventricular systolic function were analyzed and compared between the two groups. Results Standard echocardiographic studies revealed normal global left ventricular (LV) function. The LV dimensions, LV ejection fraction, LV shortening fraction, indexed LV mass did not differ between the examined groups. Among the studied LV filling parameters, peak early (E wave) transmitral flow velocity, as well as deceleration time DT, was similar between the two groups. The Tei index was also not affected by the age at repair of aortic coarctation. Regarding TDI measures, the early diastolic and the systolic velocities on the lateral side of the mitral annulus were significantly higher in group 1 than in group 2 (Sa: 12,7 ± 2,59 cm/s vs 10,6 ± 1,8 cm/s, p = 0,025; Ea : 20,7 ± 3,4 cm/s vs 17,3 ± 4,7 cm/s, p = 0,03). TDI velocities on the septal side of the mitral annulus and on the right ventricle (RV) free wall side of the tricuspid annulus were not different between early (before 2 years) and late (after 2 years) repair of the aortic coarctation. There were no differences of the TDI or conventional parameters between hypertensive and normotensive patients. Conclusion Left ventricular systolic performance in patients after the surgical repair of aortic coarctation reveals tendency to decrease at follow-up in patients repaired at age > 2 years despite a satisfactory results after surgery.
