A Rare Case Report of Takotsubo Cardiomyopathy in a Patient with Hashimoto’s Encephalopathy and Autoimmune Thyroiditis

Takotsubo cardiomyopathy (TCMP), also called as stress cardiomyopathy, is a transient left ventricular (LV) dysfunction. TCMP’s association with endocrine and thyroid diseases has been recently described, but TCMP in a patient of Hashimoto’s thyroiditis with encephalopathy is rarely reported. 1 Here, we present a recent case of TCMP in a patient with Hashimoto’s encephalopathy who was treated with steroids and responded well. Our case here highlights about having a lower threshold for screening of thyroid and other endocrine disorders in patients with TCMP.

Mechanical Circulatory Support Strategies in Takotsubo Syndrome with Cardiogenic Shock: A Systematic Review.

Takotsubo syndrome is, by definition, a reversible form of acute heart failure. If cardiac output is severely reduced, Takotsubo syndrome can cause cardiogenic shock, and mechanical circulatory support can serve as a bridge to recovery. To date, there are no recommendations on when to use mechanical circulatory support and on which device is particularly effective in this context. Our aim was to determine the best treatment strategy. A systematic literature research and analysis of individual patient data was performed in MEDLINE/PubMed according to PRISMA guidelines. Our research considered original works published until 31 July 2023. A total of 93 publications that met the inclusion criteria were identified, providing individual data from 124 patients. Of these, 62 (50%) were treated with veno-arterial extracorporeal life support (va-ECLS), and 44 (35.5%) received a microaxial left ventricular assist device (Impella). Eighteen patients received an Impella CP and twenty-one an Impella 2.5. An intra-aortic balloon pump (IABP) without other devices was used in only 13 patients (10.5%), while other devices (BiVAD or Tandem Heart) were used in 5 patients (4%). The median initial left ventricular ejection fraction was 20%, with no difference between the four device groups except for the IABP group, which was less affected by cardiac output failure (p = 0.015). The overall survival was 86.3%. Compared to the other groups, the time to cardiac recovery was shorter with Impella (p < 0.001). Though the Impella treatment is new, our analysis may show a significant benefit of Impella compared to other MCS strategies for cardiogenic shock in Takotsubo syndrome.

A contemporary update on cancer and takotsubo syndrome.

Takotsubo syndrome (TTS) is characterized by a transient left ventricular systolic dysfunction, burdened by significant acute and long-term mortality and morbidity. The prognosis of TTS, especially in the long-term, is influenced by both non-cardiovascular (non-CV) and CV comorbidities, among which cancer is one of the most common. The presence of a malignancy is proven to be associated with higher mortality in TTS. Moreover, a number of anticancer treatments has been reported to possibly cause TTS as a form of cardiotoxicity, even though clearcut associations are lacking. The aim of this narrative review is to sum up contemporary knowledge on the association of cancer and TTS, addressing unmet needs and practical implications. The importance of a close collaboration between cardiologists and oncologists is herein highlighted, both to allow an adequate management of the acute TTS phase, and to actively and safely return to the oncologic management once the acute setting is resolved.

Cardiac Nuclear Imaging Findings in Atypical Variants of Takotsubo Cardiomyopathy

Background: In addition to the typical form resembling the classical Japanese octopus trap, atypical variants of Takotsubo cardiomyopathy (TTC) sparing the left ventricular apex have emerged over the years. The aim of this systematic review is to provide a comprehensive overview of the cardiac nuclear imaging findings in atypical variants. Methods: This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The literature research was carried out online on the Pubmed, Scopus, Central (Cochrane Library), and Web Of Science databases. Results: A total of 14 articles were ultimately selected. Myocardial perfusion scintigraphy was performed in nine studies, followed by 123I-mIBG scintigraphy, 123I-BMIPP scintigraphy, and 18F-FDG PET. In seven cases, a single cardiac nuclear imaging technique was performed, while in the remaining five and two cases, two and three different imaging modalities were, respectively, used. The most common atypical variant of our selection was the midventricular form, followed by reverse/inverted/basal TTC, with only a single case reported of a focal pattern. Conclusions: As the reason why TTC variants occur is still not clear, a deeper understanding of the current knowledge could be the basis for providing more insights into this fascinating disorder and its uncommon manifestations.

Patient With Gender Dysphoria Diagnosed With Multiple Sclerosis Following Takotsubo Cardiomyopathy and Ventricular Arrhythmia: A Case Report and Systematic Literature Review.

A 34-year-old transgender woman presented with ventricular tachycardia and was diagnosed with takotsubo cardiomyopathy. Further evaluation revealed an underlying diagnosis of multiple sclerosis (MS) with brainstem lesions that may have triggered takotsubo cardiomyopathy. In this report, we also systematically reviewed published cases of takotsubo cardiomyopathy and MS and found that basal type takotsubo cardiomyopathy was the most common, and most patients presented with brainstem involvement of MS. An awareness of these associations by physicians, along with multidisciplinary collaboration, may facilitate the early diagnosis and improve the prognosis of these patients.

Investigating the effect of cancer medication in the development of Takotsubo cardiomyopathy.

Takotsubo cardiomyopathy (TCM) is a cardiac condition that is usually characterized by sudden heart failure (HF) or chest pain that resembles acute coronary syndrome (ACS). It is identified by severe systolic dysfunction of the left ventricle (LV) and can be caused by physical, medical, or emotional stress. The pathophysiological mechanisms leading to TCM have not yet been clearly determined. TCM is a complex condition to diagnose and may go undetected during cancer treatment due to the wide variety of cardiotoxic effects associated with antineoplastic therapies. Consequently, timely identification and effective treatment are critical to enhancing the prognosis. Nevertheless, TCM is a more prevalent condition in oncology than was previously believed; therefore, clinicians who treat cancer patients should consider it in their differential diagnosis. The purpose of this manuscript is to provide physicians with a summary of the available evidence regarding the ramifications of the association between TCM and cancer to aid in improving patient management.

Takotsubo Cardiomyopathy: Patients Characteristics, Mortality, and Clinical Significance of Left Ventricular Outflow Tract Gradient, Retrospective Study.

Takotsubo cardiomyopathy (TC) is a reversible left ventricular systolic dysfunction with apical ballooning. Left ventricular outflow tract (LVOT) obstruction may develop in these cases due to hyperdynamic state of the left ventricle. Limited data are available on the prevalence of LVOT gradient in TC and its association with patient outcomes and mortality. Data were collected retrospectively for patients diagnosed with TC in a single tertiary center, demographic information, blood analysis results, and imaging finding including ejection fraction, and LVOT gradient was obtained from medical records. Additionally, medical treatment and outcome during hospitalization were extracted. Follow-up was conducted through cardiology clinic or phone contact. A total of 59 patients diagnosed with TC were reviewed during hospitalization, and 40 patients were followed up after discharge by phone contact and cardiology clinic. Most patients were female (91.5%), and nonsignificant coronary artery disease was present in 16.9% of patients. Approximately two-third of the patients had a reduced ejection fraction on admission, and only two patients (5.4%) continued to have reduced ejection fraction on echocardiography follow-up within a period of 2-14 days. LVOT gradient was present in 17 patients (28.5%); patients with preserved ejection fraction had a higher probability of having an LVOT gradient. However, there was no association between LVOT gradient and shock or mortality. Four patients (6.7%) experienced 30-day mortality, while all-cause mortality was reported in eight patients (13.5%) over the follow-up period (mean (±SD) 20.8 months ± 16.2). LVOT obstruction may occur in TC patients; it has no correlation with shock or mortality. However, determining whether there is a gradient is important for deciding on specific treatment approach.

Takotsubo Syndrome Development Immediately Following Hemodialysis Initiation: A Case Report.

We herein report a case of Takotsubo syndrome in an 80-year-old woman with end-stage renal disease who hesitated to initiate hemodialysis for pulmonary edema. On hospital day 2, the patient experienced cardiac arrest. Coronary angiography after spontaneous return of circulation showed no substantial stenosis. Takotsubo syndrome was diagnosed based on echocardiography findings. On hospital day 3, she developed ventricular fibrillation but was spontaneously resuscitated. Patients with chronic kidney disease and those who postpone dialysis initiation may be at an increased risk of developing Takotsubo syndrome. Early and careful monitoring and adequate shared decision-making are essential for seamless initiation of dialysis.

Синдром Такоцубо у пациента с онкологической патологией

Oncologic disease and concomitant treatment are among the main triggers for Takotsubo syndrome. A clinical case of Takotsubo syndrome in cancer is presented. Thyroid carcinoma and thyroidectomy contributed to the development of Takotsubo syndrome. The clinical manifestations are similar to those of acute myocardial infarction. Coronarography is important in the differential diagnosis. Patients with cancer are at high risk of developing Takotsubo syndrome and should be under close clinical observation. A patient with Takotsubo syndrome should be hospitalized in an intensive care or cardiac intensive care unit. The management and treatment of patients with this pathology should be discussed by a multidisciplinary team.

Myasthenic Crisis and Concomitant Takotsubo Syndrome Complicated by Shock: A Case Report.

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.

Acute Myocardial Infarction or Broken Heart with Takotsubo Cardiomyopathy? Realm of Mystification after Suicidal Hanging

Abstract Takotsubo cardiomyopathy is a rare immune-endocrinologic cause of acute and rapidly reversible left ventricular dysfunction, usually resembling acute myocardial infarction (AMI) and triggered by emotional or physical stress. We described a case of such syndrome in a 27-year-old female after an attempted suicidal hanging, whose initial clinical symptoms and electrocardiography (ECG) findings were misleading to AMI. On admission, the patient was unconscious and hypoxic. Echocardiography demonstrated a severe left ventricular systolic dysfunction with akinesis in the mid and anterior septum and apex (a typical ballooning pattern), which raised suspicion of takotsubo cardiomyopathy. Our patient developed chest pain, a day after the suicidal attempt. Emergent coronary angiography revealed no evidence of occlusion, confirmed diagnosis of takotsubo cardiomyopathy was made. The patient was managed with medical therapy. On a week later follow-up, the patient was totally asymptomatic with a reversal of ECG changes, and the left ventricular contractility was improved within 30 days.

A Rare Case of Overlapping Durvalumab-induced Myositis, Takotsubo-like Morphological Changes Caused by Myocarditis, and Myasthenia Gravis.

Immune checkpoint inhibitors can cause a range of immune-related adverse events, including myositis, Takotsubo cardiomyopathy, and myasthenia gravis. We herein report a rare case of a 78-year-old man with concurrent durvalumab-induced myositis, Takotsubo-like morphological changes caused by myocarditis, and myasthenia gravis. The patient initially required invasive ventilation and exhibited symptoms of myasthenia gravis after treatment with high-dose steroids. However, he subsequently achieved successful recovery after the administration of intravenous immunoglobulin, plasmapheresis, and high-dose steroids. We advocate vigilant neurological monitoring of patients with immune checkpoint inhibitor-induced myositis, including the assessment of ptosis and other relevant signs, so that prompt treatment can be initiated at the time of emergence or progression of immune checkpoint inhibitor-induced myasthenia gravis.

Preventing Fluid Retention After Subarachnoid Haemorrhage During Administration of Endothelin Receptor Antagonist.

Prevention of delayed cerebral infarction (DCI) due to cerebral vasospasm after subarachnoid haemorrhage (SAH) has been done with intravenous Rho kinase inhibitors (ROCKI), ozagrel sodium (TXA2I), selective ROCKI infusion (ROCKI i.a.), and cerebrospinal fluid (CSF) drainage. The endothelin receptor antagonist (ERA, clazosentan) became available in 2022 and is said to be highly recommended for DCI prevention, while fluid retention such as pleural effusion and pulmonary oedema accumulation is often experienced. We investigated the relationship between patient background, fluid retention, and ERA. Ten consecutive SAH patients treated with ERA from July to December 2022 were included. We examined the results of blood sampling on admission, echocardiography, chest computed tomography (CT), with postoperative DCI, and hydrocephalus requiring cerebrospinal fluid shunt (hydro), and symptomatic fluid retention requiring albumin and furosemide (third fluid space). Two males and eight females, mean age 63years, mean preoperative World Federation Neurosurgical Surgeons (WFNS) grade 3.5, mean creatinine 0.94, mean brain natriuretic peptide (NT-proBNP). In 1883, two patients with Takotsubo cardiomyopathy and four patients with neurogenic pulmonary oedema are present. All patients underwent coil embolisation, and postoperative CSF drainage, ROCKI, TXA2I systemic administration, and ROCKI i.a. There were one DCI, three hydro, and five third fluid cases. Concerning the third fluid, the only significant difference was found in the age. An improvement in fluid retention after ERA discontinuation in old patients was shown. Our experience suggests that age may be the most influential factor. Based on these results, we have also found that by avoiding the use of ERA in patients older than 80years, strictly limiting the infusion volume when using ERA, and actively using the drugs for heart failure early on, the frequency of suffering from third fluid space is reduced.
