ABSTRACT: Coronary ostial stenosis after surgical aortic valve replacement (SAVR)
is a rare but potentially fatal complication. Surgeons must have a high level
of vigilance regarding the presentation of acute myocardial ischemia,
arrhythmia, and heart failure after AVR. According to most reports, this event
can be time-dependent divided into two groups; early acute phase that mostly
happens intraoperative during weaning of CPB or in early ICU stay, and late
presentation usually appears 1 - 6 months post surgery. Here, we describe an unusual subacute
presentation of right coronary ostial stenosis 12 days after SAVR, which was
treated successfully with redo beating heart coronary artery bypass grafting
(CABG).
