Conversion to sternotomy during sternal-sparing coronary artery surgery.

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques

Background:

• Sternal-sparing coronary artery surgery offers benefits but carries risks.
• Conversion to full sternotomy is a known complication, occurring in up to 1.8% of cases.
• Left internal mammary artery injury and anastomotic issues are primary causes.

Purpose of the Study:

• To retrospectively review outcomes of patients converted to sternotomy during MIDCAB.
• To identify and discuss technical aspects that may lead to conversion.
• To provide insights for avoiding sternotomy conversion in MIDCAB procedures.

Main Methods:

• Retrospective case review of six patients undergoing MIDCAB.
• Analysis of intraoperative events and reasons for conversion to sternotomy.
• Evaluation of patient outcomes post-conversion.

Main Results:

• Six patients required conversion to sternotomy during MIDCAB.
• Common causes identified included left internal mammary artery injury and anastomotic problems.
• Outcomes following conversion were analyzed.

Conclusions:

• Conversion to sternotomy is an infrequent but significant complication of MIDCAB.
• Careful attention to technical details, particularly regarding the left internal mammary artery and anastomoses, is crucial.
• Understanding these technical aspects can help minimize the need for conversion, improving MIDCAB outcomes.
