Introduction: Coronary vasospasm is a possible cause of ventricular tachyarrhythmias and is frequently associated with atherosclerotic lesions. The revascularization of mild to moderate coronary artery stenosis which causes symptoms only due to associated vasospasm is still a matter of debate, as the standard treatment of Prinzmetal angina is represented by the long term administration of calcium-channel blockers.Case presentation: We present the case of a 46 year old woman with an intermediate severity coronary artery stenosis complicated by vasospastic angina and subsequent polymorphic ventricular tachycardia. Although the functional significance of the fixed coronary artery lesion was equivocal at invasive fractional flow reserve measurement, a combined pharmacologic and interventional treatment strategy was chosen with stent implantation and long acting calcium channel blocker administration with a symptom-free, good clinical outcome.Conclusion: Patients with vasospastic angina and intermediate severity atherosclerotic coronary artery stenoses are at risk of malignant ventricular arrhythmias, therefore myocardial revascularization should be considered in addition to the standard medical treatment.
