Hemisternotomy: cardiac surgery through a smaller incision

Not all heart operations require the sternum to be fully opened. In carefully selected patients, some procedures can be performed through a more limited approach, which reduces the incision without altering the purpose of the operation.

What is a hemisternotomy

A hemisternotomy involves partially cutting the sternum, usually in the upper portion, allowing the surgeon to access the heart and great vessels. This type of approach is used primarily for interventions on the aortic valve and, in certain situations, for selected operations on the ascending aorta.

Although the incision is smaller, the procedure remains a major cardiac intervention. It requires the same rigorous planning and monitoring as a full sternotomy (complete opening of the sternum).

What benefits it offers patients

• Less trauma to the chest wall
• Reduced post-operative pain
• Shorter hospital stay
• Faster recovery and quicker return to daily activities

This method is not suitable for every condition or every anatomical profile. The decision to opt for a hemisternotomy is made following thorough imaging assessment and discussion of the case within the cardiovascular surgery team.
