Intracoronary verapamil promptly resolved distal microvascular coronary artery spasm following PTCA that was refractory to intracoronary nitroglycerin.
Does intracoronary verapamil improve distal microvascular spasm following PTCA in patients refractory to intracoronary nitroglycerin?
Intracoronary verapamil may be an effective treatment for distal microvascular spasm following PTCA that is refractory to nitroglycerin.
Absolute Event Rate: 0% vs 0%
Distal microvascular spasm is a somewhat uncommon occurrence following PTCA and often does not respond well to nitroglycerin. We report several patients who developed distal microvascular spasm that was refractory to intracoronary nitroglycerin but responded promptly to intracoronary verapamil.
Pomerantz et al. (Sun,) reported a other. Intracoronary verapamil promptly resolved distal microvascular coronary artery spasm following PTCA that was refractory to intracoronary nitroglycerin.
