Project description:Although some atypical types of transient left ventricular apical ballooning syndrome have been reported, only a few atypical types of transient mid-ventricular ballooning have been reported. A 70-year-old female underwent surgery for urothelial carcinoma. At day 5 after the surgery, she was admitted to our department without cardiac symptoms because of ST elevation in leads I, II, III, aVF and V1-V6 indicating acute coronary syndrome. She was diagnosed with stress induced cardiomyopathy based on an angiographically normal coronary artery, newly developed extensive wall motion abnormality (hyperbasal contraction and akinesis from the mid-left ventricle to the apex without hypercontraction of the small area adjacent to the apex) based on left ventriculography, and a small elevation of myocardial enzymes incongruous with the area of contraction abnormality. Myocardial scintigraphy with 99mTc-tetrofosmin showed a severely reduced myocardial perfusion in an extensive mid-ventricular area without a left ventricular base and top of apex, in accord with a wall motion abnormality different from typical apical ballooning or typical mid-ventricular ballooning previously diagnosed in our hospital. This is the first report presenting an atypical mid-ventricular ballooning based on the myocardial atypical perfusion findings.

Project description:Takotsubo cardiomyopathy can present with transient apical, midventricular, or basal left ventricular ballooning patterns. Reported recurrences of this cardiomyopathy are few. We present the cases of 2 elderly women who each had 3 episodes of takotsubo cardiomyopathy in various ballooning patterns. We explore the potential pathophysiologic mechanisms, and we discuss the best treatment approach for this disease, which carries a substantial risk of in-hospital complications.

Project description:IntroductionDobutamine stress testing is a commonly used modality in detecting and estimating the prognosis in coronary artery disease (CAD). Although it is well tolerated by most patients, adverse events have been reported. Rarely, transient wall motion abnormalities can occur in the absence of obstructive CAD to suggest stress cardiomyopathy.Case presentationWe report a 48-year-old female with intermittent chest pain. Her physical exam, cardiac enzymes and transthoracic echocardiogram were unremarkable. She underwent dobutamine stress echocardiogram to rule out obstructive CAD. After 40 micrograms (mcg)/kg/minute and 0.5 mg atropine, she complained of intense chest pain and became hypertensive. Stress echocardiogram demonstrated mid-anterior and mid-septal hypokinesis. Emergent coronary angiogram demonstrated normal coronaries. Left ventricular angiogram in the right anterior oblique projection revealed mid-ventricular ballooning during systole with apical and basal hypercontractility. Patient demonstrated excellent recovery with expectant management.ConclusionsThe mechanism of mid-variant of Dobutamine-induced stress cardiomyopathy remains unclear. We think that multiple mechanisms are involved and this risk should be considered in patients with comorbid psychiatric conditions and with use of centrally acting stimulants.

Project description:A 79-year-old woman was admitted with a left femoral neck fracture and she immediately developed circulatory shock. Echocardiography showed a markedly enlarged right ventricle (RV) with systolic ballooning of the mid-ventricular wall and preserved contractility of the apex. The left ventricular (LV) motion was normal. Multi-detector-row computed tomography showed severe congestion of the contrast media in the right atrium with no forward flow to RV, but no pulmonary embolism. She was successfully treated with percutaneous veno-arterial extracorporeal membrane oxygenation. This case presented with acute, profound, but reversible RV dysfunction triggered by acute stress in a manner similar to that seen in LV stress cardiomyopathy.

Project description:Stress cardiomyopathy, or Takotsubo syndrome, is a widely recognized cardiac pathology with a clinical presentation similar to acute coronary syndrome and related to physical or emotional stress. Perioperatively, it is challenging to identify it given the variety of forms and scenarios in which it can present. We describe a 22-year-old patient with an atypical presentation of Takotsubo syndrome during anesthesia induction, which highlights the usefulness of transesophageal echocardiography for the initial diagnosis.

Project description:BACKGROUND: Takotsubo cardiomyopathy is a novel, yet well-described, reversible cardiomyopathy triggered by profound psychological or physical stress with a female predominance. OBJECTIVE: This review is designed to increase general clinician awareness about the diagnosis, incidence, pathogenesis, and therapies of this entity. DATA SOURCES: A complete search of multiple electronic databases (Pubmed, EMBASE, Science Citation Index) was carried out to identify all full-text, English-language articles published from 1980 to the present date and relevant to this review. REVIEW METHODS: The following search terms were used: takotsubo cardiomyopathy, stress-induced cardiomyopathy, and left ventricular apical ballooning syndrome. Citation lists from identified articles were subsequently reviewed and pertinent articles were further identified. RESULTS: Takotsubo cardiomyopathy is typically characterized by the following: 1) acute onset of ischemic-like chest pain or dyspnea, 2) transient apical and mid-ventricular regional wall-motion abnormality, 3) minor elevation of cardiac biomarkers, 4) dynamic electrocardiographic changes, and 5) the absence of epicardial coronary artery disease. The pathogenesis of the syndrome is unknown but has mostly been associated with acute emotional or physiologic stressors. Dote, Sato, Tateishi, Uchida, Ishihara (J Cardiol. 21(2):203-214, 1991); Desmet, Adriaenssens, Dens (Heart. 89(9):1027-1031, Sep., 2003); Bybee, Kara, Prasad, et al. (Ann Intern Med. 141(11):858-865, Dec 7, 2004); Sharkey, Lesser, Zenovich, et al. (Circulation. 111(4):472-479, Feb 1, 2005) The short and long-term prognosis of these patients is overwhelmingly favorable and often only requires supportive therapy. CONCLUSION: Whether an emotional or physical event precedes one's symptoms, it is apparent that takotsubo cardiomyopathy case presentations mimic ST-segment elevation myocardial infarction, and thus is an important entity to be recognized by the medical community.

Project description:Background Cardiogenic shock from most causes has unfavorable prognosis. Hypertrophic cardiomyopathy (HCM) can uncommonly present with apical ballooning and shock in association with sudden development of severe and unrelenting left ventricular (LV) outflow obstruction. Typical HCM phenotypic features of mild septal thickening, outflow gradients, and distinctive mitral abnormalities differentiate these patients from others with Takotsubo syndrome, who have normal mitral valves and no outflow obstruction. Methods and Results We analyzed 8 patients from our 4 HCM centers with obstructive HCM and abrupt presentation of cardiogenic shock with LV ballooning, and 6 cases reported in literature. Of 14 patients, 10 (71%) were women, aged 66±9 years, presenting with acute symptoms: LV ballooning; depressed ejection fraction (25±5%); refractory systemic hypotension; marked LV outflow tract obstruction (peak gradient, 94±28 mm Hg); and elevated troponin, but absence of atherosclerotic coronary disease. Shock was managed with intravenous administration of phenylephrine (n=6), norepinephrine (n=6), β-blocker (n=7), and vasopressin (n=1). Mechanical circulatory support was required in 8, including intra-aortic balloon pump (n=4), venoarterial extracorporeal membrane oxygenation (n=3), and Impella and Tandem Heart in 1 each. In refractory shock, urgent relief of obstruction by myectomy was performed in 5, and alcohol ablation in 1. All patients survived their critical illness, with full recovery of systolic function. Conclusions When cardiogenic shock and LV ballooning occur in obstructive HCM, they are marked by distinctive anatomic and physiologic features. Relief of obstruction with targeted pharmacotherapy, mechanical circulatory support, and myectomy, when necessary for refractory shock, may lead to survival and normalization of systolic function.

Project description:A 48-year-old woman was scheduled by our lab to perform a standard dobutamine/atropine stress echocardiogram. During the test, the patient referred to a slight chest discomfort and developed a progressive left ventricle akinesia of all midbasal LV segments, thus mimicking a midbasal ballooning. ECG persisted without significant abnormalities and with no raise of Troponin I. Coronary angiography showed normal coronary arteries and ventriculography a severe EF reduction and apical hypercontractility. Echocardiography showed a progressive improvement with a complete recovery 48 hours later. This is a rare case of inverted takotsubo syndrome induced by dobutamine stress echocardiography that occurred with atypical presentation.

Project description:A 58-year-old Japanese female was referred to our hospital. Although the electrocardiogram showed ST elevation, coronary angiography showed intact coronary artery. We diagnosed Takotsubo cardiomyopathy and a left ventricular thrombus. Anticoagulation was administered; however, the left ventricular thrombus had become mobile and protrusive. We extirpated the left ventricular thrombus via trans-apical approach. Left ventricular thrombus is rare in Takotsubo cardiomyopathy, but these patients are at a higher risk of thromboembolism, especially if the thrombi are mobile and protruding.

Project description:BackgroundTakotsubo cardiomyopathy (TTC) is a non-ischaemic cardiomyopathy, characterized by transient wall motion abnormalities of the left ventricle. Although biventricular involvements are common with a poor prognosis, isolated right ventricular (RV) involvement of TTC is a rare, and its diagnosis remains challenging.Case presentationWe encountered a case of isolated RV-TTC presenting as acute RV failure, with progression to cardiogenic shock requiring intensive treatment. Conflicting echocardiographic findings of RV asynergy with RV enlargement despite normal left ventricular wall motion and mild tricuspid regurgitation led to the correct diagnosis. Finally, the patient showed complete recovery with normalization of cardiac structure and function.ConclusionsThis case underscores the clinical significance of considering isolated RV-TTC as a new distinct variant form of TTC in terms of presentation, diagnostic findings, differential diagnosis, treatment strategy, and prognosis.
