Insights
Percutaneous closure of post-traumatic ventricular septal defects using a patent ductus arteriosus occluder is a safe and effective treatment. This minimally invasive approach offers a viable solution for rare cardiac injuries.
Area of Science:
- Cardiology
- Cardiac Surgery
- Interventional Cardiology
Background:
- Post-traumatic ventricular septal defects (VSDs) are rare cardiac injuries.
- Percutaneous closure is an emerging treatment modality for VSDs.
- This study focuses on VSDs resulting from stab wounds.
Purpose of the Study:
- To report the experience of percutaneous closure of post-traumatic VSDs.
- To evaluate the feasibility, safety, and efficacy of this method.
- To describe the use of a patent ductus arteriosus occluder for VSD closure.
Main Methods:
- Three patients with post-traumatic VSDs (Qp/Qs > 1.7) were treated.
- VSDs were closed percutaneously using a patent ductus arteriosus occluder.
- Standard percutaneous closure techniques were employed.
Main Results:
- Post-operative echocardiography showed no residual shunt and normal ventricular function.
- 320-slice CT confirmed optimal occluder placement and morphology.
- Successful percutaneous closure was achieved in all three patients.
Conclusions:
- Percutaneous closure of post-traumatic VSDs with a PDA occluder is feasible.
- The procedure is safe and effective for selected patients.
- This technique offers a valuable alternative to surgical repair.
Objective:
Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder.
Methods:
We treated three patients with post-traumatic ventricular septal defects caused by stab wounds with knives. After the heart wound was repaired, patient examinations revealed ventricular septal defects with pulmonary/systemic flow ratios (Qp/Qs) of over 1.7. The post-traumatic ventricular septal defects were closed percutaneously with a patent ductus arteriosus occluder (Lifetech Scientific (Shenzhen) Co., LTD, Guangdong, China) utilizing standard techniques.
Results:
Post-operative transthoracic echocardiography revealed no residual left-to-right shunt and indicated normal ventricular function. In addition, 320-slice computerized tomography showed that the occluder was well placed and exhibited normal morphology.
Conclusion:
Our experiences indicate that closure of a post-traumatic ventricular septal defect using a patent ductus arteriosus occluder is feasible, safe, and effective.
