Abstract

With the aging population, more patients who have undergone previous coronary artery bypass grafting (CABG) are surviving long enough to require subsequent aortic valve replacement (AVR). Conventional redo AVR after prior CABG involves resternotomy, dissection and clamping of the patent bypass graft vessel. Favorable results have been reported for AVR following previous CABG; however, the problems of this procedure includes that injury to the patent bypass grafts can result in catastrophic complications. Increasing patient age and comorbidities may increase operative mortality, less invasive percutaneous aortic valve intervention has advanced. However, because there are no sufficient data comparing transcatheter aortic valve intervention with surgical AVR, currently, the surgical approach should still be consider as the standard of treatment for AVR following previous CABG. We report a patient in whom successful conventional AVR was underwent after previous CABG with patent left internal mammary artery.
