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.

Severe mitral valve regurgitation secondary to Libman-Sacks endocarditis.

Although uncommon, Libman-Sack endocarditis is the most characteristic cardiac manifestation of Systemic Lupus Erythematosus (SLE). It forms vegetations made of inflammatory tissue on the cardiac valves, leading them to malfunction. Here we present a case of a young woman who presented with severe mitral valve regurgitation in need for a valve replacement.

Cardiac Tamponade in a Patient With Myocardial Infarction and COVID-19: Electron Microscopy.

We present the case of a patient with myocardial infarction and COVID-19 disease who developed hemorrhagic pericardial effusion and cardiac tamponade. The differential diagnosis included post-infarction pericarditis and mechanical complications, thrombolysis, Dressler syndrome, and viral pericarditis. The histopathologic examination of the pericardial tissue sample and electron microscopic examination established the diagnosis.

Mitral Valve Malignant Primary Tumor as a Surgical Emergency: Case Report.

Malignant primary tumors of the heart are among the most unusual forms of cancer. Cardiac malignancy accounts for about 20% of all primary cardiac tumors, with most arising from the atria and less frequently the ventricles; very unusual locations include the great vessels and the cardiac valves. A rare case is presented of a young female that arrived at the authors' emergency room in pulmonary edema and circulatory collapse secondary to a true tumor of the mitral leaflets that caused severe mitral valve stenosis.

[Hypertrophic miocardiopathy. An historical and anatomopathological review].

Hypertrophic cardiomyopathy (HCM) is characterized by the presence of an abnormal hypertrophy of the left ventricle (LV), without dilation, and in the absence of any condition or another cardiac or systemic disease capable of inducing such hypertrophy. This primary or idiopathic hypertrophy can occur with or without dynamic obstruction (induced by exercise) of the LV outflow tract, so in its natural history two fundamental aspects are highlighted: the production of symptoms by blocking the LV outflow tract and the occurrence of sudden cardiac death secondary to ventricular arrhythmias. This revision includes the work of different Iberoamerican investigators, who contributed in an important way to lay the groundwork of what we know nowadays as HCM.

Mediastinal pleomorphic liposarcoma diagnosed by fine needle aspiration biopsy: a case report.

Background: Progress in radiology and pathology for diagnosing mediastinal tumors has R been made in recent decades, thanks to the use of fine needle aspiration biopsy (FNAB) guided by computed tomography, which has replaced mediastinoscopy and open biopsies.

Case: A 66-year-old male had a history o productive coughing with mucopurulent expectoration, progressive dyspnea, arthralgias, myalgias, astenia and adynamia for the previous 3 months. A CT scan and magnetic resonance imaging revealed a poorly limited tumor mass ofheterogeneous den sity in the anterior mediastinum.
