in which there is partial (either focal or fenestrated) or complete absence of the roof of the coronary sinus, which results in a communication between the coronary sinus and the left atrium. Unroofed coronary sinus is the rarest type of atrial septal defect.

How do they fix unroofed coronary sinus?

The basic repair consists of roofing the coronary sinus from within the left atrium, so that the LSVC drains through the newly created coronary sinus and its ostium into the right atrium. In the absence of a LSVC, the basic repair is simply closure of the coronary sinus atrial septal defect.

What causes dilated coronary sinus?

A dilated CS can result from increased blood flow due to abnormal venous drainage in the left superior vena cava, total anomalous intra-cardiac pulmonary venous drainage, severe tricuspid regurgitation, CS diverticulum, or a coronary artery to CS fistula.

What is coronary sinus defect?

A coronary sinus defect results in a communication of variable size between the coronary sinus (CS) and the left atrium (LA). It is in most cases associated with a persistent left superior vena cava (l-SVC) and an atrial septal defect of the coronary sinus type and often part of a more complex cardiac malformation.

What is the coronary sinus and what is its function?

The coronary sinus is the major venous tributary of the greater cardiac venous system; it is responsible for draining most of the deoxygenated blood leaving the myocardium.

How does coronary sinus work?

The function of the coronary sinus is to receive deoxygenated blood from the epicardial ventricular veins, which are the veins of the heart muscle. The coronary sinus delivers this blood to the right atrium before it eventually travels back to the lungs to be oxygenated again.

Where does coronary sinus drain into?

The coronary sinus empties directly into the right atrium near the conjunction of the posterior interventricular sulcus and the coronary sulcus (crux cordis area), located between the inferior vena cava and tricuspid valve; this atrial ostium can be partially covered by a Thebesian valve, although the anatomy of this ...

What is a coronary sinus ASD?

An isolated coronary sinus (CS) atrial septal defect (ASD) is defined as a CS unroofed in the terminal portion without a persistent left superior vena cava or other anomalies. This defect is rare and part of the wide spectrum of unroofed CS syndrome (URCS).

What is sinus venosus defect?

Sinus venosus atrial septal defect (SVASD) is a rare adult congenital heart disease which permits shunting of blood from the systemic to the pulmonary circulation and is commonly associated with anomalous pulmonary venous return.

What is ostium secundum ASD?

An ostium secundum atrial septal defect is a type of congenital heart defect called an atrial septal defect (ASD). An ASD is a hole in the wall (septum) between the two upper chambers of the heart (the atria). ASDs can be classified by location. An ostium secundum ASD is a hole in the center of the atrial septum.

How do you know you have coronary sinus?

The coronary sinus starts at the junction of the great cardiac vein and the oblique vein of the left atrium. The end of the great cardiac vein and the coronary sinus is marked by the Vieussens valve. The coronary sinus runs transversely in the left atrioventricular groove on the posterior side of the heart.

Is dilated cardiomyopathy heart disease?

Dilated cardiomyopathy is a disease of the heart muscle that usually starts in your heart's main pumping chamber (left ventricle). The ventricle stretches and thins (dilates) and can't pump blood as well as a healthy heart can.

Does atrial septal defect go away?

Small atrial septum defects may close on their own. Atrial septum defects that are large or cause symptoms can be repaired. Most children who have had an atrial septal defect repair will live healthy lives.

What is the most common association with sinus venosus ASD?

It is almost always associated with anomalous pulmonary venous drainage of the right upper pulmonary vein into the SVC. See the image below. Panel A. Transesophageal echocardiogram (transverse view) of a patient with a sinus venosus defect of the superior vena cava (SVC) type.

What does the sinus venosus do?

The Cardiovascular System

The sinus venosus collects venous blood (from the large bilateral ducti Cuvier, hepatic veins, anterior jugular veins, and the secondary circulation) and delivers it to the atrium.

What are the types of atrial septal defect?

There are 3 major types of ASDs or interatrial communications: ostium secundum, ostium primum, and sinus venosus (Figure 1A) defects. The ostium secundum is a true defect of the atrial septum and involves the region of the fossa ovalis.

What are the types of VSD?

There are four basic types of VSD:

• Membranous VSD. An opening in a particular area of the upper section of the ventricular septum (an area called the membranous septum), near the valves. ...
• Muscular VSD. ...
• Atrioventricular canal type VSD. ...
• Conal septal VSD.

What is a Perimembranous VSD?

Perimembranous ventricular septal defects (VSDs) are located in the left ventricle outflow tract beneath the aortic valve. They are the most common VSD subtype in the United States, occurring in 75-80% of cases. Defects may extend into adjacent portions of the ventricular septum.

Does the coronary sinus brings blood to the heart?

The coronary sinus collects the majority of the cardiac venous blood. It receives the blood from the myocardium, a thick layer of muscle within the heart, and facilitates the movement of the blood into the right atrium. The coronary sinus often serves as a landmark for surgeons who are performing cardiac surgery.

Which vein continues as the coronary sinus?

The great cardiac vein commonly continues until it merges with the coronary sinus [7]. The lateral veins, also known as the left marginal veins or the obtuse marginal veins, course along the left side of the heart and drain the left ventricular myocardium into the great cardiac vein or coronary sinus [7].

What is the function of the coronary sinus IVC and SVC?

The function of the coronary sinus is to drain the venous blood from the majority of the heart. It opens into the right atrium between the opening of inferior vena cava, the fossa ovalis and the right atrioventricular orifice.

What is the main tributary of the coronary sinus?

Conclusion: The utmost important vein of the heart is the coronary sinus. The tributaries of the coronary sinus are Great cardiac vein, middle cardiac vein, small cardiac vein, posterior vein of the left ventricle and oblique vein of the left atrium.

What is a sinus of the heart?

The sinoatrial or sinus node is located in the upper chamber on the right side of the heart, which is called the right atrium. The sinus node is known as the heart's natural “pacemaker,” meaning it is responsible for the rhythm of a person's heartbeats. Normal sinus rhythm is a regular rhythm found in healthy people.

Where is the sinus of the heart?

The sinus node is an area of specialized cells in the upper right chamber of the heart. This area controls your heartbeat. Normally, the sinus node creates a steady pace of electrical impulses.
