Key result
Mitral valve replacement via right minithoracotomy under ventricular fibrillation without aortic cross-clamping was successfully performed to avoid injuring a patent coronary bypass graft.
Redo mitral valve replacement through a right minithoracotomy under ventricular fibrillation without aortic cross-clamping is a feasible bailout strategy for patients with patent CABG grafts.
Right minithoracotomy MVR under VF without cross-clamping may be feasible post-CABG with patent grafts; leaves open comparative efficacy versus sternotomy.
A 61-year-old woman who has undergone coronary artery bypass grafting 30 years ago, now reveals severe mitral regurgitation. Coronary angiography and computed tomography show patency of the graft. To avoid injuring the graft, mitral valve replacement under ventricular fibrillation without aortic cross clamping was performed through a right minithoracotomy approach.
