Summary
A rare cardiac hematic endocardial cyst (HEC) was incidentally found in a 49-year-old female. This atypical presentation highlights the importance of multimodality imaging for diagnosing rare cardiac masses.
Area of Science:
- Cardiology
- Radiology
- Pathology
Background:
- Cardiac masses are rare, with primary tumors accounting for 1.5% of all primary cardiac tumors.
- Hematic endocardial cysts (HECs) are uncommon cardiac masses, often discovered incidentally.
- Clinical presentation of cardiac masses depends on size and hemodynamic impact.
Observation:
- A 49-year-old female presented with an incidentally discovered right atrial mass on computed tomography (CT).
- Echocardiography revealed a 40x40mm anechogenic ovoid mass in the right atrium, attached to the interatrial septum.
- CT angiography confirmed the mass dimensions, noting homogeneous content, calcifications, and a pedicle near the coronary sinus ostium, with no adjacent structure infiltration.
Findings:
- Surgical exploration identified an encapsulated mass with blood content, pathologically diagnosed as a hematic endocardial cyst (HEC).
- The HEC was large, located atypically in the interatrial septum, and presented anechoic content on ultrasound.
- Multimodality imaging was crucial for diagnosis and provided essential morphological and hemodynamic information.
Implications:
- This case underscores the atypical presentation of HECs, emphasizing the need for comprehensive imaging in diagnosing rare cardiac masses.
- Multimodality imaging aids in differentiating HECs from other primary cardiac tumors, guiding therapeutic decisions.
- Accurate diagnosis of rare cardiac masses like HECs is vital for patient management and preventing potential hemodynamic complications.

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
01:25Cardiomyopathy I: Introduction and Classification
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...
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...
01:29Cardiomyopathy IV: Restrictive Cardiomyopathy
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
