Background:

The ductus arteriosus is a crucial fetal blood vessel that typically closes after birth.
Failure of closure leads to patent ductus arteriosus (PDA), a common congenital heart defect requiring surgical or interventional management.
Current surgical techniques for PDA closure can be complex and may present challenges in visualization and manipulation.

Purpose of the Study:

To describe an improved surgical procedure for the patch closure of the patent ductus arteriosus.
To introduce a novel technique utilizing a Fogarty catheter integrated with a closure patch.
To enhance surgical outcomes and ease of procedure for ductus arteriosus repair.

Main Methods:

A modified surgical approach involving a patch with an integrated Fogarty catheter is detailed.
The procedure is performed under normothermic cardiopulmonary bypass.
The Fogarty catheter's balloon is inflated within the aorta to occlude the ductal orifice, allowing for precise patch placement with gentle traction.

Main Results:

The described technique facilitates improved visualization of the operative field.
Gentle traction on the catheter allows for effective plugging of the ductal orifice.
The method offers flexibility in catheter manipulation for optimal surgical access.

Conclusions:

This improved surgical procedure offers a potentially safer and more effective method for patent ductus arteriosus closure.
The use of a Fogarty catheter integrated with a patch simplifies the surgical process and improves control.
Further studies are warranted to evaluate the long-term efficacy and benefits of this technique in pediatric cardiac surgery.
