What are the 4 types of atrial septal defect?

Types of atrial septal defects include:
  • Secundum. This is the most common type of ASD . …
  • Primum. This type of ASD affects the lower part of the atrial septum and might occur with other congenital heart defects.
  • Sinus venosus. …
  • Coronary sinus.

How many types of atrial septal defects are there?

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 is the most common type of atrial septal defect?

There are three common types of atrial septal defect (ASD): Ostium Secundum – located in the center of the atrial septum (most common type) Ostium Primum – located near the lower portion of the atrial septum, may be associated with defects in the mitral and tricuspid valve (second most common type)

What are the classifications of congenital heart disease?

CHD can be subdivided in non-cyanotic CHD and cyanotic CHD which is also called critical congenital heart disease (CCHD). CCHD can be further classified into 3 different types of lesions: right heart obstructive lesions, left heart obstructive lesions, and mixing lesions.

What are the four heart defects?

The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy). They usually result in a lack of oxygen-rich blood reaching the body.

What is the normal size of ASD?

In infants, small ASDs (less than 5 mm) will often not cause problems, or will close without treatment. Larger ASDs (8 to 10 mm), often do not close and may need a procedure.

What are the 5 major classifications of birth defects?

Structural Birth Defects
  • Cleft lip or cleft palate.
  • Heart defects, such as missing or misshaped valves.
  • Abnormal limbs, such as a clubfoot.
  • Neural tube defects, such as spina bifida, and problems related to the growth and development of the brain and spinal cord.

What is a Class 3 cardiac condition?

Class III. Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary activity causes fatigue, palpitation, dyspnea, or anginal pain.

What are the 3 types of congenital disorders?

Chromosomal
  • orofacial clefts,
  • neural tube defects, and.
  • limb deficiencies.

How serious is an atrial septal defect?

Severe cases of atrial septal defects may lead to life-threatening complications such as chest pain, irregular heartbeats (arrhythmias), abnormal enlargement of the heart, a “fluttering” of the heart (atrial fibrillation), and/or heart failure.

What is the most serious heart defect?

Critical congenital heart defects (also called critical CHDs or critical congenital heart disease) are the most serious congenital heart defects. Babies with critical CHDs need surgery or other treatment within the first year of life. Without treatment, critical CHDs can cause serious health problems and death.

How many different heart defects are there?

18 Types of Congenital Heart Defects.

What is the most rare heart defect?

Hypoplastic left heart syndrome (HLHS) is a rare type of congenital heart disease, where the left side of the heart doesn’t develop properly and is too small. This results in not enough oxygenated blood getting through to the body.

Is ASD heart hereditary?

Atrial septal defect (ASD) is one of the most common types of congenital heart disease (CHD), constituting 8–10% of CHD cases in children. ASD is sometimes associated with complex CHDs or chromosomal abnormality. Although most ASDs occur sporadically, hereditary modes of inheritance have been reported.

What are the top 3 congenital heart diseases?

Here are eight of the most common types of congenital heart defects:
  • Ventricular septal defect. …
  • Atrial septal defect. …
  • Tetralogy of Fallot. …
  • Single ventricle defects.

Can atrial septal defect be cured?

Open-heart surgery.

This open-heart repair surgery is the only way to fix primum, sinus venosus and coronary sinus atrial defects. Sometimes, atrial septal defect repair can be done using small incisions (minimally invasive surgery) and with a robot (robot-assisted heart surgery).

Does ASD heart get worse with age?

Children with ASDs usually either are asymptomatic or suffer only mild exertional dyspnoea. The resultant increased pulmonary blood flow, right heart overload, arrhythmias, and pulmonary hypertension tend to increase with age. It is, however, generally accepted that life expectancy is shortened.

Why are people born with ASD?

Studies suggest that ASD could be a result of disruptions in normal brain growth very early in development. These disruptions may be the result of defects in genes that control brain development and regulate how brain cells communicate with each other. Autism is more common in children born prematurely.
