Insights

This study details a rare cardiac blood cyst in a 76-year-old man, a condition typically seen in infants. The adult case highlights the importance of considering unusual diagnoses in older patients with cardiac abnormalities like patent foramen ovale.

Area of Science:

  • Cardiology
  • Pathology

Background:

  • Cardiac blood cysts are rare, benign neoplasms, often remnants of the Chiari network, typically found in infants.
  • They usually involve cardiac valves and are seldom diagnosed in adults.

Observation:

  • A 76-year-old male presented with dyspnea and was diagnosed with a patent foramen ovale (PFO) and a mobile cystic mass in the right atrium.
  • Initial echocardiography suggested a tumor or thrombus, necessitating surgical intervention.

Findings:

  • Open-heart surgery revealed a cardiac blood cyst on the coronary sinus valve of the right atrium, containing small, stone-like structures.
  • This is the first reported case of a right atrial blood cyst with nodular structures in an adult with PFO in Iran, and the second globally.

Implications:

  • This case expands the known clinical spectrum of cardiac blood cysts to include adult presentation with PFO.
  • It underscores the need for thorough diagnostic evaluation in adults with cardiac masses, even when symptoms are atypical for common conditions.

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Overview of Systemic Veins01:11

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Chambers of the Heart01:16

Chambers 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.

Mitral Stenosis II: Clinical features and Diagnostic Tests01:23

Mitral 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...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.
