Abstract
Background: Right ventricular (RV) dysfunction in atrial switch patients has an important prognostic significance. The quantitative echocardiographic modalities (strain & strain rate) enhanced RV function noninvasive assessment. Methods: 28 patients with complete TGA who underwent Senning procedure were included and divided into 2 groups; group I: 20 patients beyond 5 years and group II: 8 patients less than 5 years. All patients were subjected to echo assessment of RV function by traditional parameters and 2D global longitudinal strain (GLS) & global systolic strain rate (GSSR) before and after low dose dobutamine stress test (2.5 µg/kg/min, increased maximally to 10 µg/kg/min). Also all patients were subjected to 24 hours Holter monitoring. Results: 2D GLS was worse in all patients than normal values (basally: -11.47±1.31% for group I and -17.78±0.96% for group II, P<0.001*) (post dobutamine: -12.30±2.93% for group I and -18.50±1.07% for group II, P<0.001*). Also, GSSR was worse (basally: -0.62±0.11/S for g
