Lipoma cardiaco / Cardiac masses

Resumen Las masas cardiacas son entidades raras que cursan con un espectro muy variado de manifestaciones clínicas que van desde cuadros asintomáticos hasta compromiso hemodinámico severo. Entre las lesiones benignas, los lipomas cardiacos son los segundos en frecuencia. Corresponden principalmente a lesiones neoplásicas benignas; no obstante, se pueden presentar otras patologías como trombos, vegetaciones y variantes de la normalidad. Gracias a la disponibilidad de técnicas de imagen de alta definición, como la ecocardiografía, la TC y la RM, ha aumentado su detección y tratamiento temprano. En el ámbito terapéutico se ofrece manejo quirúrgico, pues las imágenes no permiten la caracterización y diferenciación fidedigna de la naturaleza de las masas cardiacas. Se describe el caso de una paciente sin antecedentes cardiovasculares, con historial de disnea crónica, en quien se identificó, a través de estudios imagenológicos, masa cardiaca adosada al ventrículo con deformación leve de cavidades derechas. Fue llevada a resección quirúrgica y por histopatología se confirmó lipoma. Este hallazgo es el más infrecuente de todos los tumores cardíacos benignos. Se resalta la importancia del conocimiento de esta enfermedad para dar tratamiento eficaz y oportuno en aras de evitar complicaciones que impacten en morbimortalidad.

Abstract Cardiac masses are rare entities that present with a very varied spectrum of clinical manifestations that go from asymptomatic to pictures with severe hemodynamic compromise, within these, cardiac lipomas are the second in frequency within benign lesions. They mainly correspond to benign neoplastic lesions, however, other pathologies such as thrombi, vegetations and variants of normality can occur. Thanks to the availability of high-definition imaging techniques, echocardiography, CT and MRI have increased early detection and treatment. In the therapeutic field, surgical management is offered, since the images do not allow the characterization and reliable differentiation of the nature of cardia masses. It is described the case of a patient with no cardiovascular history, with chronic dyspnea, in whom the presence of CM attached to the ventricle with slight deformation of the right cavities is identified by imaging studies. Was taken to surgical resection confirming the presence of lipoma by histopathology, being this finding the rarest of all benign cardiac tumors. We highlight the importance of knowing this pathology to provide effective and timely treatment to avoid complications that impact morbidity and mortality.

Ethical and Clinical Dilemma from an Incidental Cardiac Lipoma in a Young and Healthy Patient

Incidental cardiac tumors are rare and mostly detected on autopsy as patients largely remain asymptomatic. However, diagnosis of an incidental cardiac mass on unrelated workup can pose significant ethical and clinical challenge to the care team. Surgical resection has been the most successful intervention for most primary cardiac tumors; which involves cardiopulmonary bypass?assisted major surgery and is not risk free. Cardiac lipoma is the second most common primary cardiac benign tumor. We report a case of a young otherwise healthy patient who had a cardiac lipoma on computerized tomography scan that was done to rule out kidney stone.

Imaging features of cardiac lipoma / 中国胸心血管外科临床杂志

@#Cardiac lipoma is rare and benign entities of heart, and often discovered after autopsy incidentally because most patients remain completely asymptomatic. The symptoms of cardiac lipoma depend on their location and size within the heart, such as dyspnea, chest pain, arrhythmia, and even sudden death. Surgical interventions usually have good results. Up till now, there has been no any relevant large-scale randomized controlled trial, and even no precise guideline for treatment. Surgical procedures often depend on patients' clinical manifestations and changes of hemodynamics in cardiac vessels in order to relief the symptoms as well as abort the progress of the disease. Therefore, early diagnosis and close follow-up are necessary for timely treatment. This article aims to summarize the imageological examinations for cardiac lipoma, including echocardiography, computed tomography, magnetic resonance imaging along with their characteristics and advantages, in order to get better clinical strategies.

Diagnóstico prenatal de lipoma cardiaco. Presentación de un caso / Prenatal Diagnose of the cardiac lipoma. Case Presentation

Presentación de caso: Se presentó esta revisión con el objetivo de abordar una entidad infrecuente en el diagnóstico de las cardiopatías fetales. Se presenta un caso de un feto con una tumoración cardíaca, cuyo diagnóstico fue realizado por estudio ultrasonográfico en el segundo trimestre del embarazo. Se describen los hallazgos ultrasonográficos y la correlación con el diagnóstico anatomopatológico. Se revisó la literatura sobre el diagnóstico histológico y ecográfico de esta cardiopatía en el desarrollo fetal.

Case Presentation: A revisal was presented with the objective to deal with an uncommon entity in the diagnoses of fetal cardiopathies. A case of a fetus is presented with a cardiac tumor, this diagnose was obtained by an ultrasonography study in the second semester of the pregnancy. Ultrasonography findings are described and the correlation with the anatomy pathological diagnose. The literature was revised about the histology and the echocardiopathy diagnosing in the fetal development.

Successful Surgical Management of Lipoma in the Right Ventricle / 日本心臓血管外科学会雑誌

We report a rare case of lipoma arising from the right ventricle. A 66-year-old woman was admitted to our hospital for exertional chest pain and fatigability. She was diagnosed of mild aortic stenosis and regurgitation (ASR), mild mitral regurgitation (MR), and asymptomatic cardiac tumor in the right ventricle about two years previously, for which she had been followed up at other local hospital. A recheck transthoracic echocardiography revealed moderate MR. No evidence of deterioration of ASR and cardiac lipoma were detected. The patient underwent mitral annuloplasty and replacement of aortic valve, plus resection of the right ventricle tumor through the tricuspid valve. Pathological examination of the resected tumor showed mature adipose tissue infiltrated into normal cardiac muscle without atypical cells, which suggested intramyocardial lipoma. Postoperative course was uneventful. Fourteen months after the operation, the patient remains asymptomatic and regular echocardiographic checkup demonstrates no tumor recurrence or residual MR.
