    Insights

    Coronary fistulae, abnormal connections between coronary arteries and heart chambers, are increasingly diagnosed. A case report highlights rheumatic heart disease as a cause, with a mural thrombus providing diagnostic clues.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Diagnostic Imaging

    Background:

    • Coronary fistulae are abnormal communications between the coronary arteries and heart chambers.
    • Improvements in selective coronary artery angiography have enhanced diagnostic capabilities for these anomalies.
    • Fistulae can be congenital or acquired, often secondary to cardiac conditions like tumors, stenosis, or aneurysms.

    Observation:

    • A patient with rheumatic heart disease presented with multiple coronary artery fistulae.
    • The fistulae were located between the coronary arteries and the left atrium.
    • A preoperatively unsuspected thin mural thrombus was discovered adhering to the left atrial wall during surgery.

    Findings:

    • The presence of a mural thrombus was crucial in identifying the pathological origin of the coronary fistulae.
    • Rheumatic heart disease was identified as the underlying condition leading to the fistulae formation.
    • Multiple fistulae involving coronary arteries and the left atrium were confirmed.

    Implications:

    • This case underscores the importance of considering acquired causes, such as rheumatic heart disease with mural thrombus, in the etiology of coronary fistulae.
    • Accurate diagnosis of coronary fistulae is essential for appropriate management and surgical planning.
    • Further research into the specific mechanisms linking rheumatic heart disease and mural thrombus to coronary fistula formation may be warranted.

    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...

    Aortic 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...

    Rheumatic Heart Disease I: Introduction

    Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

    Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

    The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
