Intracoronary infusion of nitroglycerin successfully alleviated severe multi-vessel coronary artery spasm in a 77-year-old man presenting with hemodynamic instability after aortic surgery.
Intracoronary nitroglycerin can effectively alleviate severe multi-vessel coronary artery spasm occurring early after aortic valve surgery.
May support intracoronary nitroglycerin for post-aortic surgery spasm; hypothesis-generating from single case and leaves open prospective validation.
Coronary artery spasm (CAS) refers to the spontaneous or stimuli-induced transient, often localized and intense subtotal or total constriction/occlusion of the epicardial coronary artery, usually concomitant with angina pectoris with associated elevation of the ST segment on electrocardiogram (ECG). In this article, we present a literature review on post-valvular surgery CAS and report the clinical case of a 77 year-old man who experienced severe early post-aortic surgery chest pain and hemodynamic instability. Emergent coronary angiography revealed severe occlusion of multiple branches of both coronary arteries. The CAS was alleviated with intracoronary infusion of nitroglycerin.

Formica et al. (2015) conducted a review in Post-valvular surgery coronary artery spasm (n=1). Intracoronary infusion of nitroglycerin was evaluated on Alleviation of coronary artery spasm. Intracoronary infusion of nitroglycerin successfully alleviated severe multi-vessel coronary artery spasm in a 77-year-old man presenting with hemodynamic instability after aortic surgery.
