A case report: biventricular takotsubo cardiomyopathy with sequential ventricular recovery due to pulmonary hypertension.

ABSTRACT:

Background

Biventricular Takotsubo cardiomyopathy (BTC) is estimated to occur in 25-42% of those with Takotsubo cardiomyopathy (TC). Little is known about which subset of patients are predisposed to having concomitant right ventricular (RV) involvement, or the pattern of recovery in BTC.

Case summary

We describe a 69-year-old woman who presented with dyspnoea and was subsequently diagnosed with BTC. We propose that this was triggered by an exacerbation of chronic obstructive pulmonary disease on a background of multiple predisposing factors including recent bereavement, previous excessive alcohol use, status as a current smoker, and anxiety. During her admission, she required non-invasive ventilation and inotropic support to manage her type two respiratory failure and acute heart failure. Serial echocardiograms during the admission allowed us to capture and present the sequential recovery of ventricular systolic function, with the left ventricular (LV) recovery preceding the right ventricle.

Discussion

Our patient fulfils the International Takotsubo Diagnostic criteria of transient LV dysfunction, emotional and physical triggers, electrocardiogram abnormalities, raised troponin and brain natriuretic peptide and no occlusive coronary artery disease. We hypothesize that pulmonary hypertension-related strain on the right ventricle due to lung disease, may have led to the observed delay in the recovery of RV function, despite the full recovery of LV function.

Biventricular takotsubo cardiomyopathy: case report and general discussion.

Project description:In recent years, our understanding of the physiologic mechanisms of transient takotsubo cardiomyopathy has improved because of the growing use of emergent heart catheterization in patients who present with severe ischemic syndromes. However, even this procedure has revealed only that, in most patients with takotsubo syndrome, the sudden onset of ventricular dysfunction is not due to fixed coronary artery occlusions. We present a case of transient takotsubo cardiomyopathy with an exceptional feature--uneven impairment of both right and left ventricular function, or biventricular takotsubo--and we discuss a novel, comprehensive theory that we have devised to explain the pathophysiology of this syndrome's many manifestations.

Case report: recurrent biventricular Takotsubo cardiomyopathy in a middle-aged man with fatal outcome after full recovery.

Project description:BackgroundTakotsubo cardiomyopathy (TC) usually manifests as transient apical ballooning of the left ventricle and may mimic acute coronary syndrome. Concomitant right ventricle involvement may occur in about a third of the cases. Recurrence had been observed in up to 10% of TC with variable ventricular involvement. Despite this knowledge, there had been no report of a patient with multiple biventricular TC in the literature to date. In this study, we describe a rare case of a patient who presented twice with biventricular TC.Case summaryA 52-year-old man with a previous episode of biventricular TC 5 months ago presented to our hospital with a 1 day history of shortness of breath and wheeze. He was treated initially for infective exacerbation of chronic obstructive airway disease. He was eventually intubated following a trial of non-invasive ventilation. He became hypotensive post-intubation and required intensive care support. An inpatient echocardiogram revealed biventricular apical ballooning. Invasive coronary angiogram showed no coronary artery disease. A repeat echocardiogram 14 days post-admission demonstrated full recovery of both ventricles. These findings were consistent with a second biventricular TC. Two months later, he was found deceased in the community seemingly from an unrelated cause.DiscussionThis case describes a middle-aged gentleman who suffered recurrent biventricular TC with no consistent triggers and an unrelated fatal sequel. None of these features were typical, and to our best knowledge had not been reported before. We hypothesize that his recurrent chronic obstructive pulmonary disease exacerbations and various substance misuse might have predisposed him to this unusual presentation.

Ventricular Septal Perforation after Biventricular Takotsubo Cardiomyopathy Successfully Repaired with an Amplatzer Device: First Report in the Literature.

Project description:A 79-year-old female was admitted with sudden onset dyspnea, mild oppressive chest pain, and severe anxiety disorder. Patient had history of hypertension, dyslipidemia, smoking, and chronic obstructive pulmonary disease. On admission blood pressure was 160/90 and heart rate was 130 bpm. Transthoracic echocardiography (TE) and contrast tomography showed a thin septum with an abnormal left and right ventricular contraction with an "apical ballooning" pattern and mild increase of cardiac enzymes. At the 4th day of admission, the patient presented symptoms and signs of congestive heart failure and developed cardiogenic shock. EKG showed an inversion of T waves in all precordial leads. In a new TE, a ventricular septal perforation (VSP) in the apical portion of the septum was seen. Coronary angiogram showed angiographically "normal" coronary arteries. With a diagnosis of VSP in takotsubo cardiomyopathy, a percutaneous procedure to repair the VSP was performed 11 days after admission. The VSP was closed with an Amplatzer device. TE performed 24 hours after showed significant improvement of ventricular function and good apposition of the Amplatzer device. Three days later she was discharged from the hospital. To our knowledge, this is the first reported case of a VSP in a TCM repaired percutaneously with an occluder device.

Biventricular takotsubo cardiomyopathy: case study and review of literature.

Project description:Biventricular takotsubo cardiomyopathy is associated with more hemodynamic instability than is isolated left ventricular takotsubo cardiomyopathy; medical management is more invasive and the course of hospitalization is longer. In March 2011, a 62-year-old woman presented at our emergency department with abdominal pain, nausea, and vomiting. On hospital day 2, she experienced chest pain. An electrocardiogram and cardiac enzyme levels suggested an acute myocardial infarction. She underwent cardiac angiography and was found to have severe left ventricular systolic dysfunction involving the mid and apical segments, which resulted in a left ventricular ejection fraction of 0.10 to 0.15 in the absence of obstructive coronary artery disease. Her hospital course was complicated by cardiogenic shock that required hemodynamic support with an intra-aortic balloon pump and dobutamine. A transthoracic echocardiogram revealed akinesis of the mid-to-distal segments of the left ventricle and mid-to-apical dyskinesis of the right ventricular free wall characteristic of biventricular takotsubo cardiomyopathy. After several days of medical management, the patient was discharged from the hospital in stable condition. To the best of our knowledge, this is the first review of the literature on biventricular takotsubo cardiomyopathy that compares its hemodynamic instability and medical management requirements with those of isolated left ventricular takotsubo cardiomyopathy. Herein, we discuss the case of our patient, review the pertinent medical literature, and convey the prevalence and importance of right ventricular involvement in patients with takotsubo cardiomyopathy.

Isolated right ventricular takotsubo cardiomyopathy presenting as acute right ventricular failure: A case report.

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.

Isolated Right Ventricular Stress (Takotsubo) Cardiomyopathy.

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.

Cardiogenic shock due to Takotsubo cardiomyopathy associated with thyroid crisis: a case report

Project description:Abstract Background The development of cardiogenic shock due to the coexistence of Takotsubo cardiomyopathy and thyroid crisis in patients has been scarcely reported. Case summary A 46-year-old female presented with chest pain, palpitations, nausea, and vomiting for 8 h. She was initially considered to have acute myocardial infarction due to elevated cardiac markers and abnormal electrocardiogram changes. Immediately after the coronary angiography revealed a normal coronary artery, the patient developed refractory cardiogenic shock. Echocardiography demonstrated a typical apical ballooning type of Takotsubo cardiomyopathy with a left ventricular ejection fraction (LVEF) of 32%. A combination of norepinephrine and dopamine and an intra-aortic balloon pump (IABP) was used to support haemodynamic stability but failed to improve the patient’s condition. Immediately after the laboratory tests revealed previously unknown hyperthyroidism on the second hospital day, a rapid atrial fibrillation (AF) suddenly occurred. Nifekalant successfully restored sinus rhythm in a short time. The patient persistently complained of chest tightness, palpitations, and sweating for the first 4 days until levosimendan and antithyroid crisis treatment were used. Discussion Takotsubo cardiomyopathy and thyroid crisis can co-occur and present as cardiogenic shock. In the presence of severe cardiac dysfunction and untreated hyperthyroidism, nifekalant is an ideal option for the new onset of AF. The combination of heart failure treatment and antithyroid crisis drugs can effectively restore cardiac function and is associated with good clinical outcomes.
