Intracoronary ATP resolves refractory RCA spasm and stabilizes cardiac function in a post-AVR patient.
Case Report (n=1)
May support intracoronary ATP for refractory post-AVR spasm; hypothesis-generating pending controlled trials.
A 62-year-old woman underwent aortic valve replacement for aortic stenosis. Her hemodynamics deteriorated with ST-T depression 6 hours postoperatively. Emergency coronary catheterization showed diffuse right coronary artery spasm. The spasm persisted despite intracoronary infusion of nitrates and calcium antagonists. Intracoronary adenosine triphosphate infusion finally resolved the spasm and stabilized the cardiac function.

Song et al. (2006) conducted a case report in Refractory Coronary Artery Spasm (n=1). Intracoronary adenosine triphosphate was evaluated on Resolution of spasm and stabilization of cardiac function. Intracoronary adenosine triphosphate infusion successfully resolved refractory right coronary artery spasm and stabilized cardiac function in a 62-year-old woman post-aortic valve replacement.
