Coronary Spasm and Polymorphic Ventricular Tachycardia One Year After Takotsubo

Stress cardiomyopathy is typically considered to be a disease with a favorable long-term prognosis, with malignant arrhythmias accompanying only the acute phase. We describe a 51-year-old female who presented with palpitations one year after stress cardiomyopathy and complete recovery of apical left ventricular wall motion. Coronary spasm was strongly suspected based on transient ST-segment elevations followed by sustained polymorphic ventricular tachycardia captured on ambulatory Holter. Contrast injection during coronary angiography reproduced spasm and ventricular arrhythmia that resolved with intracoronary nitroglycerine. The patient was intolerant to nitrates therefore discharged on 2 calcium channel blockers. Shared decision was made to implant cardioverter defibrillator.
