Abstract:
Background: Ventricular Septal Defect (VSD) is one of the most common congenital cardiac diseases, accounting for 20%, and affects the left ventricular function. There is no study on the application of Tei index to evaluate left ventricular function in patients with VSD in Vietnam. Objective:To assess left ventricular function in ventricular septal defect by Tei index. Subject and Method: A cross-sectional descriptive study that involves 35 patients of VSD with an average age of 15.77+/-10.41 (A group: 19 patients of VSD with systolic pulmonary artery pressure (PAPs) < 40 mmHg and B group: 16 patients of VSD with PAPs>=40mmHg and control group: 30 normal volunteers). Results: Tei index for estimation of left ventricular function is higher in the VSD (0.50+/- 0.18) than the control (0.37 +/- 0.03) with p < 0.01, exponentially more in the VSD with PAPs >=40mmHg (0.64 +/- 0.15; p<0.01). Conclusion: Left ventricular function is worse in VSD patients in comparison to the healthy people.
