Summary
A rare quadricuspid tricuspid valve, an uncommon congenital heart anomaly, was found during a cadaver dissection. This finding suggests potential lifelong valvular dysfunction and right-sided heart issues.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Anatomical Pathology
Background:
- Quadricuspid heart valve anomalies are rare congenital malformations.
- While typically affecting the aortic valve, involvement of the right atrioventricular (tricuspid) valve is exceedingly uncommon.
- Tricuspid valve formation involves complex embryological processes of endocardial cushion fusion and delamination.

01:16Chambers of the Heart
10.0K
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.

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...

01:15Aortic Regurgitation I: Introduction
1.6K
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
