    Quadricuspid semilunar valves are rare congenital heart anomalies. This autopsy review found quadricuspid pulmonic valves more common than aortic valves, with some cases linked to severe infant heart disease.

    Area of Science:

    • Cardiovascular Pathology
    • Congenital Heart Disease
    • Autopsy Studies

    Background:

    • Quadricuspid semilunar valves are uncommon congenital cardiac malformations.
    • Understanding their prevalence and associated pathologies is crucial for diagnosis and management.

    Purpose of the Study:

    • To review autopsy cases of quadricuspid semilunar valves.
    • To determine the ratio of quadricuspid pulmonic to aortic valves.
    • To identify associated congenital cardiac defects and clinical outcomes.

    Main Methods:

    • Retrospective review of 47 autopsy cases with quadricuspid semilunar valves.
    • Analysis of valve type (pulmonic vs. aortic) and coexisting cardiac anomalies.

    Main Results:

    Related Experiment Videos

    • The ratio of quadricuspid pulmonic to aortic valves was 5:1.
    • Of 35 quadricuspid pulmonic valves, 10 had coexisting defects, 8 causing severe cyanotic heart disease in infancy.
    • Of 7 quadricuspid aortic valves, 3 had aortic insufficiency.

    Conclusions:

    • Quadricuspid pulmonic valves are more frequent than quadricuspid aortic valves.
    • Congenital cardiac defects, including severe cyanotic heart disease, can be associated with quadricuspid pulmonic valves.
    • Quadricuspid aortic valves may present with aortic insufficiency or be incidental findings.
