Insights
Two-dimensional speckle tracking echocardiography (2D-STE) effectively assesses right ventricular function after percutaneous atrial septal defect (ASD) closure. This technique offers detailed cardiac insights, supporting its use in clinical practice.
Area of Science:
- Cardiology
- Echocardiography
- Congenital Heart Disease
Background:
- Atrial septal defect (ASD) is a common congenital anomaly potentially leading to right ventricular (RV) dysfunction.
- Percutaneous closure is a standard, effective treatment for ASD worldwide.
- Assessing postoperative RV function changes requires reliable methods.
Purpose of the Study:
- To evaluate the outcomes of percutaneous ASD closure using two-dimensional speckle tracking echocardiography (2D-STE).
- To assess the efficacy of 2D-STE in monitoring cardiac function post-procedure.
Main Methods:
- A non-experimental study involving 22 patients undergoing percutaneous ASD closure (2016-2018).
- Echocardiographic assessments were performed pre-procedure, 24 hours post-procedure, and one month post-procedure.
- RV strain rate and other indices were measured and compared across time points.
Main Results:
- A significant difference (P < 0.050) was observed in RV middle septal wall strain rate before and one month after the procedure.
- RV strain patterns improved one month post-procedure, though not always significantly (P > 0.050).
Conclusions:
- 2D-STE provides a rapid and detailed assessment of cardiac chambers and function.
- STE may serve as a valuable alternative to traditional echocardiographic methods for cardiac function testing.
- Further research with larger cohorts and extended follow-up is recommended to validate these findings.
Background:
Atrial septal defect (ASD) is among the most common congenital anomalies that its neglect may cause severe right ventricular (RV)-associated cardiac dysfunction. Percutaneous closure of ASD is an efficient technique used commonly worldwide. Varieties of techniques have been used to assess postoperative changes of cardiac function. The current study has aimed to assess outcomes of percutaneous ASD closure using two-dimensional speckle tracking echocardiography (2D-STE).
Methods:
This non-experimental research was conducted on 22 patients who volunteered for percutaneous ASD closure between 2016 and 2018. Cases were assessed three times including prior to percutaneous ASD closure, after 24 hours, and a month after procedure. Cases outcomes were assessed and compared during the time.
Results:
Strain rate in RV middle septal wall was significantly different (P < 0.050) between before and one month after the procedure. Comparison of indices post procedure and one month later showed better RV strain pattern but they did not have a significant difference (P > 0.050).
Conclusion:
Based on this research, STE is a quick simple method of assessing cardiac chambers and function in details. It seems that this method can replace other traditional echocardiographic methods for cardiac function tests; thus, further studies with larger groups and longer follow-up duration are strongly recommended.
