Multimodal imaging in Ig G4- related aortitis: case report.

We present the case of a 56-year-old patient with fever of unknown origin associated with chest and lumbar pain. Multimodality imaging revealed diffuse peri-aortitis in the thoracic aorta without involvement of the aortic valve, contributing substantially to the diagnosis of Ig G4-associated aortitis. Immunosuppressive therapy was started. Follow-up at five months with cardiac magnetic resonance imaging showed a reduction in the inflammatory process in the thoracic aorta.

Presentamos el caso de un paciente de 56 años, con cuadro febril de origen desconocido asociado a dolor torácico y lumbar. La imagen multimodal demostró periaortitis difusa en la aorta torácica sin afectación de la válvula aórtica, lo que contribuyó sustancialmente al diagnóstico de aortitis asociada a Ig4. Se inició tratamiento inmunosupresor. El seguimiento a los 5 meses, la resonancia magnética cardíaca mostró una reducción del proceso inflamatorio en la aorta torácica.

Takotsubo syndrome and atrial myxoma-identifying a new trigger: a case report.

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.

Collection of cardiac masses. Up-to-date echocardiography and cardiac MRI tools.

Heart masses, including tumors (primary and secondary) and pseudotumor (cysts and thrombus), are rare entities, but of increasing interest in cardiac imaging areas. The clinical manifestations are related to the intracardiac effect of mass, embolization, and systemic symptoms in the case of tumors; however, some of them are detected incidentally. Nowadays, imaging techniques and the advancement of their tools perform the morphological, functional, and tissue characterization of the masses, and additionally know the anatomical relationships, which are crucial factors for the treatment and surgical planning.

[Imagen multimodal de la pericarditis constrictiva: reporte de un caso de cirrosis cardiaca]. / Multimodal imaging in constrictive pericarditis: a case report of cardiac cirrhosis.

Constrictive pericarditis is a rare cause of ascites and cardiac cirrhosis. We present the case of a 36-year-old male patient with a history of cirrhosis of unknown etiology, who consulted for refractory ascites, dyspnea, and lower limb swelling. Echocardiography determined constrictive pericarditis, which was corroborated by the findings of computed tomography. The clinical and hemodynamic worsening of the patient led to an emergency pericardiectomy with satisfactory recovery. This report shows a severe clinical consequence of constrictive pericarditis, cardiac cirrhosis, which was reversible with pericardial extirpation. Multimodal imaging was essential in the diagnosis of constrictive pericarditis.

[Comparative analysis of myocardial deformation in patients recovered from mild SARS-CoV-2 infection]. / Análisis comparativo de la deformación miocárdica en pacientes recuperados de infección leve por SARS-CoV-2.

Objectives: During acute infection by the SARS-CoV-2 virus, myocardial involvement has been demonstrated; it is unknown if cardiovascular sequelae in patients recovered from this infection and if these are associated with global morbidity and mortality. The objective of this study was to compare myocardial deformation in patients recovered from mild SARS-CoV-2 virus infection with healthy controls. Materials and methods: This was a cross-sectional observational study that included 33 subjects recovered from mild SARS-CoV-2 infection, who were diagnosed in the previous three to six months, and 31 healthy volunteers, both groups free of cardiovascular risk factors. The study of myocardial deformation was performed using echocardiography with the speckle tracking modality. Clinical and anthropometric variables were compared. Results: The 2D global longitudinal strain of the left ventricle was lower in the subjects recovered from mild SARS-CoV-2 infection than the controls (-20.2% ± 2.6 v -21.6% ± 2.4; p: 0.036). Both groups presented differences in the three ventricular levels, significant at the apical level (-21.2 ± 4.0 vs -23.4% ± 4.2; p: 0.044). The effect by levels shows an inverse Takotsubo pattern. The left ventricular ejection fraction was preserved in both groups (p: 0.153). Conclusions: Left ventricular myocardial deformation is affected in subjects recovered from mild SARS-CoV-2 infection, while the ejection fraction was found in normal ranges. Our study shows a potential role of global longitudinal strain in the detection of subclinical myocardial alterations in patients who had SARS-CoV-2.
