Insights
Diagnosing and treating patent ductus arteriosus (PDA) often involves catheterization. A left internal mammary artery (LIMA) angiographic catheter was successfully used for PDA passage in 15 adult patients without complications.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Patent ductus arteriosus (PDA) diagnosis and treatment typically necessitate cardiac catheterization.
- Standard catheterization routes for PDA involve passage from the aorta to the pulmonary artery or vice versa.
- Previous literature lacks reports on utilizing a left internal mammary artery (LIMA) angiographic catheter for PDA procedures.
Purpose of the Study:
- To evaluate the feasibility and safety of using a LIMA angiographic catheter for trans-PDA catheterization.
- To assess the utility of the LIMA catheter in obtaining pressure gradients across the PDA.
Main Methods:
- A LIMA angiographic catheter was successfully advanced from the aorta across the PDA into the pulmonary artery.
- The procedure was performed in 15 adult patients.
- Catheter passage and patient outcomes were monitored for complications.
Main Results:
- Successful passage of the LIMA angiographic catheter through the PDA was achieved in all 15 patients.
- No complications were reported during or after the catheterization procedure.
- This demonstrates the LIMA catheter's potential utility in PDA interventions.
Conclusions:
- The LIMA angiographic catheter is a safe and effective tool for trans-PDA catheterization in adult patients.
- This novel approach offers a potential alternative for diagnostic and interventional procedures related to PDA.
- Further studies may explore its application in diverse patient populations and specific clinical scenarios.
Abstract:
The diagnosis of patent ductus arteriosus (PDA) usually requires catheterization, as does percutaneous treatment of the disorder. To obtain pressure gradients, a catheter can be passed in either direction through the PDA, from the pulmonary artery to the aorta or via the more common route of aorta to pulmonary artery. Several types of catheters have been used, but to date there have been no reports showing the use of a left internal mammary artery (LIMA) angiographic catheter for this purpose. We report successful passage of this catheter from the aorta across a PDA to the pulmonary artery in 15 adult patients who were observed to have no complications.
