Summary
A rare epicardial cyst compressing the left ventricle caused syncope in an 8-year-old girl. Surgical resection was successful, highlighting the importance of considering cardiac cysts in pediatric syncope.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Cardiac Surgery
Background:
- Syncope in children can have various causes, including cardiac abnormalities.
- Epicardial cysts are rare congenital anomalies that can present with diverse clinical manifestations.
Observation:
- An 8-year-old girl presented with new-onset syncope.
- Echocardiography revealed a cystic structure compressing the left ventricle.
- Imaging suggested a simple pericardial cyst, but surgery revealed an epicardial cyst.
Findings:
- The epicardial cyst partially involved the circumflex branch of the left coronary artery.
- Cardiopulmonary bypass was required for complete cyst resection.
- A small portion of the cyst contiguous with the coronary artery was left in situ.
Implications:
- This case underscores the diagnostic challenge of differentiating pericardial and epicardial cysts.
- Early diagnosis and surgical management are crucial for favorable outcomes in pediatric cardiac cyst cases.
- Accurate preoperative imaging and intraoperative assessment are vital for managing cysts involving coronary arteries.

01:27Anatomy of the Heart
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
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.
01:15Layers of the Heart Wall
The heart wall comprises three distinct layers: the epicardium, myocardium, and endocardium. The outermost layer, the epicardium, is the visceral layer of the serous pericardium, featuring a thin, transparent mesothelial surface and an inner layer of areolar connective tissue with fat deposits that increase with age.
The myocardium, the thickest layer, consists of cardiac muscle cells interconnected by intercalated discs and crisscrossing connective tissue fibers. These muscle fibers contract...

01:16Chambers of the Heart
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
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...
