Early-Onset Cardiomyopathy After Pacemaker Implanted in a Preterm Infant With Congenital Complete Heart Block and Anti-Ro/SSA Antibodies.

Congenital complete heart block is a potentially fatal complication that can occur in neonates whose mothers have autoimmune disorders; it has rarely been reported in the presence of Sjögren syndrome. Pacemaker implantation is recommended to treat rhythm abnormalities in these neonates. We report the case of a late-preterm infant with Sjögren-syndrome-antibody-induced complete heart block who underwent temporary bipolar epicardial pacing as a bridge to permanent pacemaker implantation. Soon after the pacemaker was implanted, takotsubo cardiomyopathy developed. To our knowledge, this is the first report of reversible cardiomyopathy after pacemaker implantation in an infant.

Rapid, Fatal Acute Right Ventricular Failure After Locoregional Cytokine Therapy for Uveal Melanoma Liver Metastases.

Locoregional cytokine treatment, or immunoembolization, is an experimental targeted therapy for uveal melanoma metastatic to the liver. Unlike systemic cytokine treatments that have been associated with substantial toxicity, this method of drug delivery appears to be better tolerated. Because this newer therapy is being prescribed more widely, oncologists, interventional radiologists, cardiologists, pulmonologists, critical care specialists, and other providers should become familiar with potential adverse reactions. We describe the case of a 67-year-old man who had metastatic uveal melanoma. Before he underwent liver-directed immunoembolization, he had elevated markers of endothelial dysfunction. He died after the rapid onset of acute right ventricular failure from severe pulmonary hypertension with possible superimposed isolated right ventricular takotsubo cardiomyopathy. In discussing this rare case, we focus on the differential diagnosis.

Pheochromocytoma-Induced Takotsubo Cardiomyopathy.

Pheochromocytoma, a rare catecholamine-secreting tumor, typically manifests itself with paroxysmal hypertension, tachycardia, headache, and diaphoresis. Less often, symptoms related to substantial hemodynamic compromise and cardiogenic shock occur. We report the case of a 66-year-old woman who presented with abdominal pain. Examination revealed a large right adrenal mass, cardiogenic shock, and severe heart failure in the presence of normal coronary arteries. Within days, the patient's hemodynamic status and left ventricular ejection fraction improved markedly. Results of imaging and biochemical tests confirmed the diagnosis of pheochromocytoma-induced takotsubo cardiomyopathy. Medical therapy and right adrenalectomy resolved the patient's heart failure, and she was asymptomatic postoperatively. We recommend awareness of the link between pheochromocytoma and takotsubo cardiomyopathy, and we discuss relevant diagnostic and management principles.

Cardiomiopatia de Takotsubo após pneumonia: relato de caso / Takotsubo cardiomyopathy after pneumonia: case report

Também chamada de Síndrome do Coração Partido, a Síndrome de Takotsubo é uma doença cardiovascular com quadro clínico semelhante ao infarto agudo do miocárdio, porém, com coronárias normais na cineangiocoronariografia. Normalmente está associado a quadros de estresse emocional ou físico sendo necessário o conhecimento da patologia para diagnóstico e boa condução do caso. O objetivo deste estudo foi relatar um caso clínico de uma paciente com cardiomiopatia de Takotsubo após pneumonia e internação hospitalar. A importância do tema é ressaltada pela raridade do tema e pelo seu subdiagnóstico. Mulher,77 anos com história de disfagia de transferência evoluindo após 10 dias com tosse produtiva de coloração amarelada. Diagnosticada e internada com pneumonia broncoaspirativa e iniciada antibioticoterapia. No sétimo dia de internação evoluiu com precordialgia associada a dispneia. História mórbida de acidente vascular cerebral (AVC) isquêmico há 4 anos com sequela de hemiplegia esquerda e crises convulsivas. O eletrocardiograma (ECG) demonstrou supradesnivelamento do segmento ST emparede ântero-septal. À cinecoronariografia ausência de lesões obstrutivas significativas e à ventriculografia e ecocardiograma discinesia de ventrículo esquerdo com abalonamento ântero-infero-apical. No caso descrito os fatores desencadeantes ficaram claros sendo o estresse físico pela pneumonia e emocional pela internação hospitalar. O quadro clínico apresentado pela paciente associado a cinecoronariografia, ecocardiografia e eletrocardiografia e o padrão de reversibilidade da disfunção cardíaca nos remetem ao diagnóstico de Cardiomiopatia de Takotsubo.

Also called the Broken Heart Syndrome, Takotsubo syndrome is a cardiovascular disease similar to acute myocardial infarction clinical, however, with normal coronary arteries on coronary angiography. Is usually associated with events of emotional or physical stress. The knowledge of pathology for diagnosis and good management of the case is necessary. The aim of this study was to report a clinical case of a patient with Takotsubo cardiomyopathy after pneumonia and hospitalization. The importance of this issue is underscored by the rarity of the subject and its underdiagnosis. Female, 77 years with a history of dysphagia transfer evolving after 10 days with cough productive of yellowish. She was diagnosed with aspiration pneumonia and hospitalized with antibiotic therapy initiated. On the seventh day of hospitalization developed chest pain associated with dyspnea. Morbid history of ischemic stroke 4 years ago sequel with left hemiplegia and seizures. The ECG showed ST segment elevation in the anteroseptal wall. In the absence of significant obstructive coronary angiography and ventriculography lesions and echocardiographic left ventricular dyskinesia with anterior infero-apical bulging. In the case described, the triggering factors were the physical and emotional stress by the pneumonia and hospitalization. The clinical presentation by the patient associated with coronary angiography, echocardiography and electrocardiography and standard reversibility of cardiac dysfunction refer us to diagnosis of the Takotsubo Cardiomyopathy.
