REDO
Pronunciation: REE-do
Repeat cardiac surgery in a previously operated chest, presenting increased technical complexity and risk.
Full Definition
A cardiac surgical procedure performed in a patient who has previously undergone cardiac surgery, requiring re-entry through a previously opened chest. REDO operations present significant technical challenges due to adhesions between the heart and surrounding structures, making dissection dangerous and time-consuming. The risk of injury to cardiac structures, grafts, or great vessels is substantially higher than in primary operations. Special precautions include having cardiopulmonary bypass ready before chest opening and careful planning of the surgical approach.
Usage
Usage note: Often written in capitals; implies previous cardiac surgery through same incision.
