Abstract Background Takotsubo cardiomyopathy is a transient left ventricular dysfunction with an established recurrence rate in populations, however, recurrences in the same individual have not been well described. Case summary We present a 76-year-old woman who had likely a total of six recurrent takotsubo cardiomyopathy episodes spanning over 33 years. Her diagnosis of takotsubo cardiomyopathy was first made in 2014 when she presented with chest pain, raised cardiac enzymes, and the presence of normal coronary arteries. Cardiac magnetic resonance was performed, ruling out any current or previous myocardial infarction. Subsequently, she had two further recurrences in 2015 and 2018. Stressors were identified on three occasions. She was diagnosed with ‘myocardial infarction’ in 1986, 1988, and 1998 when she presented with chest pain and electrocardiogram changes, despite demonstrating normal coronary arteries on each occasion. Discussion This case demonstrates three confirmed recurrent episodes of takotsubo in the same individual, showing three different left ventricular phenotypic morphologies on the background of three previous episodes of ‘myocardial infarction with normal coronary arteries’, which most likely might have been takotsubo episodes as well. Any myocardial infarction-type injury was definitely ruled out in the 2014 admission instigating a potential change in this patient’s past medical history and implicitly requirement for lifelong secondary prevention. It is notably difficult to make a confirmed diagnosis of takotsubo cardiomyopathy back in 1986, 1988, and 1998 due to the lack of awareness in this novel topic.

Abstract Background Patients with myocarditis often present with angina pectoris despite unobstructed coronary arteries. The underlying pathophysiological mechanism of angina in these patients remains to be elucidated. Coronary artery spasm is a well-known cause of angina in patients with unobstructed coronary arteries. In this study, we sought to assess the frequency of coronary vasomotor disorders in patients with biopsy-proven viral myocarditis. Methods In total, 700 consecutive patients who underwent endomyocardial biopsy for suspected myocarditis between 2008 and 2018 were retrospectively screened. Of these patients, viral myocarditis was confirmed in 303 patients defined as histological/immunohistological evidence of myocardial inflammation and presence of viral genome confirmed by PCR. Of these patients, 34 patients had angina despite unobstructed coronary arteries and underwent intracoronary acetylcholine (ACh) provocation testing in search of coronary spasm. Epicardial spasm was defined as acetylcholine-induced reproduction of the patient's symptoms associated with ischemic ECG changes and >90% epicardial vasoconstriction. Microvascular spasm was defined as symptom reproduction and ECG changes in the absence of significant epicardial vasoconstriction. Results Patients were 49±16 years old, 62% were male and left ventricular ejection fraction was 54±16%. Most frequent viruses were parvovirus B19 (PVB19, 59%) and human herpes virus 6 (HHV6, 26%), 2 patients had combined PVB19/HHV6 infection and 3 patients other herpesviruses (CMV, EBV, VZV). Epicardial spasm was observed in 10 patients (29%) during ACh testing and microvascular spasm was found in 11 patients (32%). The rate of coronary spasm (epicardial and microvascular) was higher in the PVB19 subgroup compared to HHV6 (80% vs. 33%, p=0.031). In particular, there was a higher prevalence of microvascular spasm in PVB19 compared to HHV6 (45% vs. 0%, p=0.018). Conclusion We observed a high prevalence of microvascular and epicardial spasm in patients with biopsy-proven viral myocarditis suggesting coronary spasm as a potential underlying mechanism for angina in these patients. Microvascular spasm was most often observed in patients with PVB19-associated myocarditis. Funding Acknowledgement Type of funding source: Foundation.
