Displacement of the heart by a giant mediastinal cyst
The American Journal of Cardiology
|September 1, 1977
Insights
A large mediastinal cyst mimicked constrictive pericarditis by displacing the heart. Echocardiography, angiography, and surgery confirmed the cyst as the cause, not pericardial disease.
Area of Science:
- Cardiology
- Thoracic Surgery
- Diagnostic Imaging
Background:
- Mediastinal masses can present with diverse clinical manifestations.
- Cardiac displacement by non-cardiac masses can lead to diagnostic challenges.
Observation:
- A giant mediastinal cyst was identified as the cause of significant cardiac displacement.
- The cyst led to apparent cardiomegaly and symptoms mimicking constrictive pericarditis.
Findings:
- Echocardiography was crucial in identifying the mediastinal cyst and its effect on cardiac structures.
- Angiography and surgical intervention confirmed the diagnosis and differentiated it from pericardial disease.
Implications:
- Accurate diagnosis of mediastinal masses is essential to avoid misdiagnosis of cardiac conditions.
- Advanced imaging and surgical evaluation are vital for managing complex thoracic pathologies.
Abstract:
A giant mediastinal cyst caused marked cardiac displacement, factitious cardiomegaly and clinical and hemodynamic findings suggestive of constrictive pericarditis. The correct diagnosis was established with echocardiography and confirmed with angiography and surgery.

01:13Location and Orientation of the Heart
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.
01:22Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:25Hiatal Hernia
A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...
