PROSTHETIC HEART VALVES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Corrected TGA occurs when the anatomic right ventricle becomes the arterial ventricle and the anatomic left ventricle becomes the venous ventricle
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -TGA occurs when the two main blood vessels coming out of the heart-the aorta and the pulmonary artery-are transposed, or switched in position. The aorta is positioned in front of the pulmonary artery instead of behind it.

Detailed explanation-2: -Corrected transposition of the great arteries is a very rare heart defect in which the heart’s lower two pumping chambers, the ventricles, are reversed in their positions. It affects about 1 in 25, 000 births and occurs equally in boys and girls. Early in fetal life the heart first forms in the shape of a tube.

Detailed explanation-3: -Treating L-TGA In more serious L-TGA cases, patients may have surgery to close holes in the heart (ASDs or VSDs) or to repair valves. A more complicated surgery, called a double switch operation, may be needed to relieve the right ventricle and make the left ventricle the pump to the body.

Detailed explanation-4: -Congenitally corrected transposition of the great arteries (CCTGA) is a rare congenital cardiac anomaly defined by atrio-ventricular and ventriculo-arterial discordance. This malformation makes up less than 1% of congenital heart defects.
