Abstract

Background: Coronary ostial stenosis is an uncommon but potentially lethal complication following aortic root replacement with or without aortic valve replacement (including Bentall and David procedures). This manifests clinically as acute myocardial ischaemia in the early or late post-operative period. Traditionally, this might be managed with redo open-heart surgery. Case summary:  This case series describes two presentations where urgent percutaneous coronary intervention was used to manage myocardial infarction complicating aortic root surgery with coronary reimplantation. Discussion: This series highlights the risk of acute myocardial infarction after cardiac surgery involving coronary reimplantation. Emergency percutaneous coronary intervention is feasible and illustrates the importance of shared post-operative care involving the cardiac surgeons and the cardiology team.
