Median full-sternotomy carries a risk of sternal infection and lethal mediastinitis in cardiac surgery. We performed open-heart surgery through partial median sternotomy in 5 patients with tracheostomy. Coronary artery bypass grafting (CABG) was performed in 3 patients, aortic valve replacement in 1, and mitral valve replacement in 1. No operative deaths or complications related to wound infection occurred. Partial sternotomy represents a safe alternative in cardiac surgery in patients with tracheostoma.
