| Summary: | This study delineates the diagnostic and therapeutic strategies for acute myocardial infarction occurring years after stent implantation for Stanford type A aortic dissection. Emergency coronary angiography presented substantial technical challenges attributable to the lack of recent aortic imaging data and marked tortuosity of the brachiocephalic trunk resulting from postoperative anatomical changes. Consequently, while selective left coronary angiography was successfully completed, visualization of the right coronary artery necessitated non-selective contrast administration via a pigtail catheter. This case underscores the pivotal role of preoperative aortic computed tomography angiography (CTA) in hemodynamically stable patients, as it provides essential vascular anatomical information that may circumvent procedural complexities during coronary angiography. Building upon these observations, we advocate an “aorto-coronary combined assessment” strategy for post-aortic surgery patients, integrating systematic imaging surveillance to facilitate early identification of coronary lesions. Such an approach permits the timely implementation of intensive medical therapy or elective revascularization, thereby mitigating the risk of acute cardiovascular events. |
