Magnetic resonance imaging and echocardiography in assessment of ventricular function in atrially corrected transposition of the great arteries.

摘要: Objective: Patients with atrial correction of transposition the great arteries (TGA) may develop right ventricular (RV) failure time. A reliable non-invasive method for assessment function is therefore needed. To evaluate accuracy echocardiography in volumes and these patients we compared magnetic resonance imaging (MRI) 10 late after Mustard Senning procedures. Design: Prospective MRI examinations were performed on same day. Two different technicians examined all patients. All at university hospital outpatient clinic department respectively. Ten patients, age 14.0 ± 2.9 years, who had been operated TGA 8 (2-60) months (median range) examined. Echocardiography RV left (LV) end-systolic (ESVs), end-diastolic (EDVs), stroke (SVs) ejection fractions (EFs) calculated, using modified Simpson method, measurements obtained from MRI. Results: For there was good agreement between echocardiography- MRI-derived measurements. Both revealed reduced EFs 42.6 9.1% 46.4 7.2% no significant differences LV significantly overestimated by (EF = 72.7 4.4% vs. 50.5 7.6%) while greatly underestimated. repeated showed large variations, 13-50%, variables individual Conclusion: can provide clinically important information concerning follow-up TGA. It has limited value Volume are, however, highly user-dependent interobserver variation high. accordingly serve as an reference
