Evaluation of the Ventricular Mechanical Dyssynchrony in Patients with Atrial Septal Defect |
|
| چکیده انگلیسی مقاله |
Background: There is some evidence indicating improvement in myocardial performance after atrial septal defect closure, either device closure or surgical, but ventricular dyssynchrony has not been evaluated before and after surgical closure. The aim of this study was to evaluate ventricular mechanical dyssynchrony in patients with atrial septal defect before and after surgical closure. Methods: Twenty patients (mean age: 23±11years) with isolated secundum or sinus venosus type atrial septal defect, unsuitable for device closure, were evaluated before and after successful surgical closure. Interventricular and intraventricular dyssynchrony (using 6 basal and 6 mid-segmental models) were determined. Results: A significant reduction in the right atrial and right ventricular dimensions and the tricuspid regurgitation peak gradient was noted after atrial septal defect closure (3.6±0.54 cm versus 4.2±0.7, P=0.009; 3.5±0.29 cm versus 4.3±0.41, P=0.02; and 20.4±10.5 mmHg versus 35.3±6.5, p Conclusion: There was no significant ventricular dyssynchrony in the patients with atrial septal defect before and after surgical closure. |
