Right Anterior Minithoracotomy for Redo Aortic Valve Replacement After Coronary Artery Bypass Grafting with Bilateral Internal Thoracic Artery: a Case Report

A 63-year-old male, with a history of coronary artery bypass grafting using bilateral internal thoracic artery grafts, underwent surgical aortic valve replacement. Avoiding the graft injury, we selected the right anterior mini-thoracotomy approach under cardiac arrest with systemic hyperkalemia with remaining bilateral internal thoracic artery grafts open. Deep hypothermia was induced to obtain more reliable myocardial protection. We believe this strategy can be considered as a therapeutic option in patients requiring aortic valve replacement but unsuitable for transcatheter aortic valve replacement.
