A 78-year-old male patient with complete atrioventricular block underwent an uncomplicated pacemaker implantation. After 24 h, he presented acute chest pain, dyspnea, ST-segment-elevation in the anterior leads, left ventricular apical ballooning, and an ejection fraction of 35%. His coronary angiogram was normal. Within 2 days, his symptoms and electrocardiogram (ECG) abnormalities disappeared, while wall motion abnormalities recovered after 6 weeks. A diagnosis of takotsubo syndrome (TTS) was made. Pacemaker implantation has been described as a potential trigger for TTS. The clinical picture exhibits some peculiarities, including a higher percentage of men and asymptomatic patients and challenging ST-segment interpretation of paced ECGs. It is unclear whether pathophysiologic mechanisms are different compared to other forms of TTS and whether the acute initiation of ventricular pacing plays a role.

A man in his 80s with myasthenia gravis (MG) developed dysmobility and chest discomfort. An electrocardiogram revealed ST-segment elevation, and coronary angiography revealed Takotsubo syndrome (TTS). He experienced myasthenic crisis that required ventilation and shock that was refractory to vasopressors and required intra-aortic balloon pump (IABP) insertion. He was managed conservatively without MG-specific treatment until his hemodynamics improved. On hospital day 6, he was weaned from IABP. MG is a high-risk condition for TTS, and TTS with MC is associated with high mortality. We successfully managed this case of TTS with MC with intubation and IABP, without MG-specific treatment.

UNASSIGNED: Thousands of people suffer from anxiety, depression, and insomnia every day, with benzodiazepines being one of the strategies used to treat these conditions. Withdrawal from its long-term use can lead to potentially life-threatening complications, including Takotsubo syndrome. The authors highlight an atypical case of Takotsubo syndrome secondary to benzodiazepine withdrawal, a rare life-threatening complication of acute substance withdrawal.
UNASSIGNED: A 58-year-old female presented to the emergency department with altered mental status and acute pulmonary oedema after discontinuing her prescribed benzodiazepines 3 days prior to presentation. Electrocardiogram (ECG) demonstrated anterior ST-segment elevation, with Q-wave and T-wave inversion with prolonged QT interval. Troponin I concentration and B-type natriuretic peptide were elevated to 5407 ng/L (normal ≤ 16 ng/L) and to 1627.0 pg/L (normal ≤ 100 pg/mL), respectively. Echocardiogram showed ballooning of the left ventricle (LV) apex with dyskinesia of the mid and apical segments, with LV function of 15%. Coronary angiography was normal, but left ventriculography showed severe LV systolic dysfunction with akinesis of the mid and apical LV segments and hyperdynamic basal segments. A presumptive diagnosis of benzodiazepine withdrawal-induced Takotsubo syndrome was made, and patients\' symptoms, ECG findings, and LV dysfunction resolved after benzodiazepine administration. Six months post discharge, the patient remained asymptomatic with a normal biventricular function, and a beta-blocker was successfully introduced as part of a lifelong plan.
UNASSIGNED: A diagnosis of benzodiazepine withdrawal-induced Takotsubo syndrome is an underrecognized and challenging diagnosis, due to its atypical clinical presentation. High degree of clinical suspicion for this syndrome is crucial, since favourable prognosis depends on prompt diagnosis and treatment.

UNASSIGNED: Takotsubo syndrome (TTS) mimics acute coronary syndromes but can lead to serious cardiac complications, emphasizing the need for improved understanding and management.
UNASSIGNED: We describe a TTS case presented with cardiogenic shock due to ventricular septal rupture (VSR). Successful treatment involved mechanical circulatory support followed by VSR surgical closure.
UNASSIGNED: Ventricular septal rupture is the rarest and deadliest complication associated with TTS. Prompt recognition and a multidisciplinary approach are crucial to achieve the best possible outcome.

UNASSIGNED: Cardiac complications represents a major cause of morbidity and mortality especially after bilateral simultaneous total knee arthroplasty (BS-TKA). Takotsubo syndrome after BS-TKA has not been described in the literature.
UNASSIGNED: A 60 years-old women underwent BS- TKA and she suddenly developed bradycardia and hypotension after second knee wound closure. The electrocardiography revealed ST elevation and echocardiography showed apical hypokinesia of left ventricle. Coronary angiography revealed normal epicardial coronaries and a provisional diagnosis of Takotsubo cardiomyopathy was made. Serial ECGs revealed resolution of ST elevation and normal LV function within 5 days. On one-year follow up, she was able to do all her normal activities, and 12-lead electrocardiography were back to normal.
UNASSIGNED: Cardiac complications represents a major cause of morbidity and mortality especially after BS-TKA. Surgeons must be vigilant in the postoperative period for any likely precipitating factors of stress induced cardiomyopathy. Takotsubo syndrome should be considered as a differential diagnosis with features of acute coronary syndrome in elderly post-menopausal patients.

The patient, a 68-year-old man, presented to our emergency room with chest pain, prompting an emergency cardiac catheterization due to elevated cardiac troponin-I levels. While no obvious coronary artery stenosis was found, there was evidence of apical ballooning wall motion in the left ventricle, leading to a diagnosis of takotsubo syndrome. Three months later, he occasionally experienced chest pain at rest, prompting us to conduct another cardiac catheterization. Left ventriculography showed normal contraction. Suddenly, he experienced chest pain accompanied by ST elevation, which occurred spontaneously. Subsequently, slow-flow phenomenon was observed in the intermediate part of left anterior descending artery (LAD). We promptly administered nitroglycerin to alleviate the symptoms. Following the diagnosis of coronary microvascular dysfunction (CMD), he started calcium-channel blocker therapy and remained asymptomatic. One year later, we re-performed cardiac catheterization to further explore his condition. Acetylcholine provocation test was performed, which showed no epicardial coronary spasm. However, lactic acid elevation was observed in the coronary sinus blood sample. Additionally, a coronary physiological measurement in the LAD revealed a high index of microcirculatory resistance and low coronary flow reserve. Based on this series of clinical events, we inferred a significant contribution of CMD to the patient\'s condition.
UNASSIGNED: Coronary microvascular dysfunction (CMD) is increasingly recognized as an important cardiovascular disease, leading to myocardial ischemia, which is occasionally associated with takotsubo syndrome (TTS). In this report, we present a case of spontaneous CMD associated with TTS. This case emphasizes the significance of accurate diagnosis and appropriate treatment, highlighting the importance of recognizing CMD in patients with TTS.

UNASSIGNED: Takotsubo syndrome (TTS) causes angina with ventricular dysfunction that can mimic acute coronary syndrome. Normal coronary angiography leads to cardiovascular magnetic resonance imaging (CMR) in the diagnostic pathway. Historically, TTS was thought to be associated with the absence of late gadolinium enhancement on CMR. This case report highlights the presence of late gadolinium enhancement in a case of TTS while demonstrating the other characteristic findings, including quantitative parametric T1/T2 mapping.
UNASSIGNED: A 69-year-old lady was admitted with chest pain and shortness of breath. She was found to have classical TTS with the characteristic wall motion abnormalities on echocardiogram, left ventricular angiogram, and CMR. Her CMR also demonstrated strongly positive myocardial T1/T2 mapping that matched the wall motion abnormalities and the less frequently described positive early and late gadolinium enhancement.
UNASSIGNED: This case highlights the diagnostic pathway in TTS and the ability of CMR to make a diagnosis in myocardial infarction with non-obstructed coronary arteries. We describe the characteristic cardiac imaging features of TTS while discussing the positive late gadolinium enhancement patterns that may help confirm the diagnosis.

Takotsubo syndrome (TTS) is a rare cardiomyopathy, but its prevalence is increasing due to the greater availability of diagnostic tools, whose pathophysiology is unknown; however, the evidence points to an excess of catecholamines that ends up generating cardiac stunning. The cause of excessive sympathetic discharge is multifactorial, and some tumors may be related to their origin. In this case report, we present a female patient with TTS whose only identified triggering factor was an atrial myxoma, which generated an unusual clinical presentation. Current multimodal diagnostic tools together with the multidisciplinary evaluation of the HeartTeam allowed an accurate diagnosis and an adequate management of the clinical picture.

We present the case of a 32-year-old woman with a diagnosis of lumbar root syndrome and spondylolisthesis, which is why she underwent surgery. Anterior discectomy and intersomatic box placement plus posterior fixation were performed with percutaneous transpedicular screws in L5-S1. At 24 hours of the procedure, the patient presents sustained hypotension, adding sudden and intense chest pain with neck irradiation, dyspnea, and diaphoresis, as well as electrocardiographic abnormalities and elevation of cardiac enzymes suggestive of an acute coronary syndrome, subsequently evidence of basal hypokinesis in the echocardiogram. After providing hemodynamic support and analgesic management, the symptoms were resolved, and the electrocardiogram (ECG) and cardiac enzymes were normalized, allowing an adequate postoperative evolution.

UNASSIGNED: Takotsubo syndrome (TTS) is characterized by acute left ventricular dysfunction, mimicking an acute myocardial infarction, in the absence of obstructed coronary arteries. It is often triggered by physical or emotional stress, with catecholamines playing a central role in its pathophysiology. Recent advances have been made in categorizing TTS patients based on trigger events and comorbidities, as well as proposed classifications differentiating primary and secondary TTS. In-hospital triggers for (secondary) TTS appear to be quite common, and our aim is to bring attention of this prevalent phenomenon.
UNASSIGNED: We present the clinical course of an 80-year-old man who developed TTS after witnessing the sudden death of his roommate during his hospital stay. Initially hospitalized for bradycardia and complete atrioventricular block, the patient was discharged after a pacemaker implantation. However, he returned to the hospital 3 days later with chest pain and other symptoms indicative of TTS. Diagnostic tests confirmed apical ballooning consistent with TTS, and subsequent echocardiograms showed a substantial improvement in left ventricular function.
UNASSIGNED: The case is classified as in-hospital TTS, occurring unexpectedly during medical care, and suggests that secondary TTS could represent a certain \'basic risk\' for hospitalized patients. We want to emphasize the importance of reducing pain and fear in the hospital setting and encourage further research to understand the association between TTS and medical procedures and therapies. Overall, this case underscores the need for strategies to reduce the frequency of TTS in hospitalized patients.
