Intracoronary papaverine may trigger torsades in patients with hypokalemia or alkalosis; single case leaves open true incidence and risk mitigation.
Case Report (n=1)
Intracoronary papaverine can induce torsades de pointes, particularly in patients with additional risk factors for repolarization disturbances such as hypokalemia and alkalosis.
Vrolix et al. (1991) conducted a case report in Critical stenosis in the proximal part of the circumflex artery (n=1). Intracoronary papaverine was evaluated on Papaverine-induced ventricular arrhythmia (torsades de pointes). Intracoronary papaverine administration for coronary flow reserve assessment induced torsades de pointes in a 49-year-old man with hypokalemia and alkalosis.
