Could the novel 'double-hole' technique be an alternative for the inflow occlusion method?

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Surgical Techniques

Background:

• Existing methods for cardiac foreign body removal, including inflow occlusion and cardiopulmonary bypass, have limitations and complications.
• A novel 'double-hole' technique is introduced as an alternative approach.
• This technique involves opening the right atrium without the need for cardiopulmonary bypass.

Purpose of the Study:

• To describe and evaluate a novel 'double-hole' technique for cardiac chamber foreign body removal.
• To present an alternative to traditional methods that avoids cardiopulmonary bypass.
• To explore the potential utility of this technique, particularly in complex surgical cases.

Main Methods:

• The study utilized bovine hearts obtained from a local supermarket for procedural simulation.
• Two purse-string sutures were placed in the right atrium using 2-0 braided, non-absorbable polyester suture material.
• A guidewire from a haemodialysis catheter was inserted via the superior vena cava into the right atrium and advanced through the right ventricle.

Main Results:

• The 'double-hole' technique was demonstrated on bovine hearts.
• The technique's applicability was suggested, especially in revision cases involving adhesions.
• Further research is recommended to establish the method's efficacy and safety.

Conclusions:

• The 'double-hole' technique is a novel approach for cardiac chamber foreign body removal.
• While promising, extensive research is required to validate its utility in contemporary cardiovascular surgery.
• The technique has the potential to become a safe, practical, and effective future surgical measure.
