Echocardiography (Mount Kisco, N.Y.)
|February 15, 2011
Summary
An elongated eustachian valve and patent foramen ovale were identified in a patient experiencing syncope. Echocardiography revealed a linear density obstructing inferior vena cava flow in the right atrium.
Area of Science:
- Cardiology
- Diagnostic Imaging
- Anatomy
Background:
- Syncope necessitates comprehensive cardiac evaluation.
- Transthoracic echocardiography is a key diagnostic tool for cardiac abnormalities.
Observation:
- A 64-year-old male presented with syncope.
- Echocardiography revealed a linear density in the right atrium.
- Inferior vena cava (IVC) inflow obstruction was noted, but superior vena cava (SVC) inflow was unobstructed.
Findings:
- Agitated saline injection confirmed functional right atrial separation by the density.
- Contrast crossed the interatrial septum rapidly, indicating a patent foramen ovale.
- The findings are consistent with an elongated eustachian valve.
Implications:
- This case highlights the importance of echocardiography in diagnosing uncommon cardiac anomalies.
- Understanding eustachian valve anatomy is crucial for interpreting right atrial dynamics.
- Patent foramen ovale may be implicated in syncopal events.

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.

Heart Valves
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Anatomy of the Heart
The heart is a hollow, muscular organ approximately the size of a fist, consisting of four chambers. It is enclosed in the pericardium, a fibrous sac with two layers: the visceral and parietal pericardium, separated by a fluid-filled space containing serous fluid to reduce friction.
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

Anatomy 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.
Development of the Heart
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart tube by...

Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
