Off-pump myocardial revascularization. The single-suture technique: how to avoid any complication

Area of Science:

• Cardiac Surgery
• Minimally Invasive Procedures
• Vascular Surgery

Background:

• Coronary artery bypass grafting without cardiopulmonary bypass (off-pump CABG) is an established revascularization technique.
• Historically limited to specific arteries, advancements now enable complete off-pump myocardial revascularization.
• Previous pericardial suturing techniques for circumflex artery exposure posed risks to nearby organs.

Purpose of the Study:

• To present a modified single pericardial suture technique for improved exposure of the circumflex coronary artery.
• To mitigate risks of injury to adjacent structures like the esophagus, aorta, and pulmonary veins during off-pump CABG.

Main Methods:

• Description of a novel single pericardial suture placement in the oblique sinus.
• Focus on achieving adequate surgical exposure of the circumflex territory with reduced cardiac manipulation.
• Emphasis on avoiding damage to posterior pericardial structures.

Main Results:

• The modified suture technique facilitates effective exposure of the circumflex coronary artery.
• This approach aims to prevent reported complications such as esophageal or aortic injury and pulmonary vein damage.
• The method seeks to reduce the incidence of subcutaneous emphysema observed in prior experiences.

Conclusions:

• A modified pericardial suture technique offers a safer approach to off-pump coronary artery bypass grafting.
• This modification enhances surgical access to the circumflex territory while improving patient safety.
• Further evaluation is warranted to confirm the long-term benefits and safety profile of this technique.
