FE Congenital Heart Disease Recognition 1

Question 1

Which congenital heart defect is characterized by a single outflow tract from the ventricles?

Accepted Answer

Truncus arteriosus

Answer

Truncus arteriosus is a rare congenital heart defect characterized by a single great artery arising from both ventricles, instead of the normal separate aorta and pulmonary artery. This single vessel overrides a large ventricular septal defect, serving as the common outflow tract for systemic, pulmonary, and coronary circulation. This condition is distinct from other defects by its singular outflow tract.

Question 2

Which condition presents with a large ventricular septal defect and overriding aorta?

Accepted Answer

Tetralogy of Fallot

Answer

Tetralogy of Fallot is a complex congenital heart defect characterized by four main features: a large ventricular septal defect (VSD), pulmonary stenosis, an overriding aorta, and right ventricular hypertrophy. The overriding aorta, positioned directly above the VSD, receives blood from both ventricles. This combination of defects leads to reduced blood flow to the lungs and mixing of oxygenated and deoxygenated blood.

Question 3

Which congenital heart disease features complete reversal of the great arteries?

Accepted Answer

Transposition of the great arteries

Answer

Transposition of the great arteries (TGA) is a congenital heart defect where the two main arteries leaving the heart are completely reversed. The aorta originates from the right ventricle and the pulmonary artery from the left ventricle. This creates two separate, parallel circulatory systems, meaning deoxygenated blood circulates to the body and oxygenated blood circulates to the lungs, a condition incompatible with life without mixing.

Question 4

Which heart defect is associated with an absent or small left ventricle?

Accepted Answer

Hypoplastic left heart syndrome

Answer

Hypoplastic left heart syndrome (HLHS) is a severe congenital heart defect where the left side of the heart is critically underdeveloped. This includes a very small or absent left ventricle, often accompanied by hypoplasia of the aorta and abnormalities of the mitral and aortic valves. As a result, the left side of the heart is unable to effectively pump blood to the body, requiring complex surgical intervention.

Question 5

Which echocardiographic view best identifies ventricular septal defects (VSD)?

Accepted Answer

Four-chamber view

Answer

The four-chamber view in echocardiography provides a comprehensive image of both atria and ventricles, along with the atrioventricular valves. This view is crucial for identifying ventricular septal defects (VSDs) because it allows direct visualization of the interventricular septum. Any communication or hole between the ventricles can be clearly seen, making it the best view for VSD detection.
