Getting by with less - the "frugal tie"

Area of Science:

• Cardiovascular Surgery
• Medical Device Implantation
• Surgical Techniques

Background:

• Effective surgical knot tying is crucial for pacemaker implantation to secure device generators and leads.
• Current techniques often require significant suture slack, posing challenges in confined spaces.
• Preventing dislodgement and ensuring proper device packaging are vital for patient outcomes.

Purpose of the Study:

• To present a novel surgical knot-tying technique.
• To address the challenge of limited suture slack during pacemaker implantation.
• To improve the efficiency and security of device anchoring.

Main Methods:

• A modified surgical knot-tying technique is described, combining elements of the 2-handed square knot and 1-handed surgeon's knot.
• The technique is designed to facilitate knot completion with minimal remaining suture length.
• Focuses on practical application in pacemaker generator pocket closure.

Main Results:

• The new technique allows for secure knot tying and device anchoring despite limited suture slack.
• Demonstrates feasibility in scenarios where traditional methods may be difficult to execute.
• Offers a viable alternative for challenging pacemaker implantation cases.

Conclusions:

• The novel knot-tying technique provides an effective solution for securing pacemaker devices with minimal suture slack.
• This method enhances surgical adaptability and potentially improves procedural efficiency.
• Contributes a valuable skill to the armamentarium for cardiovascular implant procedures.
