RESUMO
Infective endocarditis (IE) is a condition that predominantly affects native or prosthetic heart valves, which is currently on the rise due to the increase in invasive cardiology procedures, such as the utilization of cardiac implantable electronic devices and transcatheter interventions. The recommended imaging tests for diagnosis are 2D transthoracic echocardiography (2D TTE) and 2D transoesophageal echocardiography (2D TOE). However, these modalities present limitations in detecting vegetations and estimating their dimensions. These disadvantages can be overcome by 3D transoesophageal echocardiography (3D TOE), particularly with the multiplanar reconstruction tool, which allows for the visualization of infinite valve planes, thus optimizing the detection of lesions and precise measurements. Furthermore, the volume rendering provides insight into the anatomical relationships between lesions, which is particularly useful for surgical planning. In this review, we aim to discuss the role of this recent imaging modality in the diagnosis, prognosis, and therapeutic of IE. Finally, we present a collection of images that illustrate the use of 3D TOE tools.
RESUMO
Aortic stenosis is associated with aortic plaques in up to 85% of cases because they share risk factors and pathogenic pathways. Intrinsically, complex aortic plaques carry a high risk of stroke, which has also been demonstrated in the context of aortic stenosis, especially in patients who underwent percutaneous or surgical replacement. Transesophageal echocardiography (TEE) is the imaging test of choice to detect plaques in the thoracic aorta and classify them as complex plaques. Furthermore, the 3D modality allows us to better specify its dimensions and anatomical characteristics, such as added thrombi or the presence of ulcers inside. This review aims to evaluate the use of TEE to detect complex aortic plaques in patients with an indication for percutaneous or surgical aortic valve replacement. To highlight the association between aortic stenosis and complex aortic plaques, we attached to the review some TEE studies from our experience.
La estenosis aórtica se asocia con placas aórticas hasta en un 85% de los casos, porque comparten factores de riesgo y vías patogénicas. Intrínsecamente, las placas aórticas complejas conllevan un alto riesgo de accidente cerebrovascular, lo que también se ha demostrado en el contexto de estenosis aórtica, especialmente en pacientes sometidos a reemplazo percutáneo o quirúrgico. La ecocardiografía transesofágica (ETE) es la prueba de imagen de elección para detectar placas en la aorta torácica y clasificarlas como placas complejas. Además, la modalidad 3D nos permite precisar mejor sus dimensiones y características anatómicas como trombos añadidos o la presencia de úlceras en su interior. Esta revisión tiene como objetivo evaluar el uso de ETE para detectar placas aórticas complejas en pacientes con indicación de reemplazo valvular aórtico percutáneo o quirúrgico. Para resaltar la asociación de estenosis aórtica y placas aórticas complejas adjuntamos a la revisión algunos estudios de ETE de nuestra experiencia.
RESUMO
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.
RESUMO
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.

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.
RESUMO
Ventricular septal rupture (VSR) is a rare and devastating complication of acute myocardial infarction. Early detection, assessment of the hemodynamic impact, and illustration of the pathophysiological context are crucial functions of echocardiography in decision-making for intensive management and reparative intervention. To evaluate this entity, echocardiography exhibits two strengths: its bedside nature and its multiple modalities. This document reviews the comprehensive use of echocardiography in the study of post-infarction VSR.

We present the case of a 53-year-old patient with a giant floating thrombus in the aortic arch associated with proximal stenosis of the left subclavian artery diagnosed by multimodal imaging. Left carotid-subclavian shunt and thoracic endovascular aortic repair (TEVAR) were successful. Transesophageal echocardiography (TEE) played a substantial role in the safety and efficacy of the endovascular procedure and should be considered as an additional guide to fluoroscopy for this type of procedure.

Rheumatic heart disease is the leading cause of cardiovascular disease in children under 25 years of age worldwide, with the highest prevalence in low-income countries. The usual and distinctive finding of rheumatic aggression is mitral stenosis, which leads to serious cardiovascular consequences. International guidelines establish transthoracic echocardiography (TTE) as the diagnostic test for rheumatic heart disease; however, it has limitations in the measurement of planimetry and those inherent to Doppler. Transesophageal 3D echocardiography (TTE-3D) is a new modality that shows realistic images of the mitral valve and has the added value of accurately locating the plane of maximum stenosis and better determining commissural involvement.
