Case summary:
Mr. M is born with transposition of the great arteries, in which aorta arises from the right ventricle and the pulmonary artery arises from the left.
Adequate information:
The two great arteries help in the transportation of blood from the heart. These two great arteries are pulmonary artery and aorta. The pulmonary artery which is attached to the right ventricle carries blood from the heart to the lungs where it receives oxygen then it enters the left ventricle. The aorta is attached to the left ventricle that carries oxygenated blood from the heart to other parts of the body.
To determine:
The flow of blood through the pulmonary and systemic route arteries in transposition condition. The ability of the cardiovascular system to deliver oxygen to the systemic tissue is to be determined. Also, the requirement of the correction method is to be determined.
Given Information:
The transposition of the great arteries that includes aorta and pulmonary artery affects the flow of blood. In this condition, the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. This change in structure produces the anatomical abnormalities.

- Given a disruption in the structure or function of the cardiovascular system such as pulmonary edema, what possible factors or situations might have created that disruption? Please answer in detailarrow_forwardIf a stent is not used in a few cases who have coronary angioplasty done, the artery tends to narrow down or get blocked again in 6 months. This is more likely to happen if: (a) one smokes (b) one has unstable angina before the procedure (c) one has diabetes (d) all of thesearrow_forwardRight to left shunting is a consequence of congenital abnormalities of the Heart. The major symptom associated with this is cyanosis. What are the four main abnormalities that lead to this condition and what is the terminology that is used for these abnormalities?arrow_forward

Name all the arterial structures, in order, that the balloon catheter passes through from the right femoral artery to the right coronary artery.arrow_forward
- Circulation of blood inside a human fetus’ body is different than that of an adult. Describe one functional or structural difference between adult and fetal circulation (other than the size of the organs), and explain why it is important during development.arrow_forwardTell which vessel is missing from the following vascular circuit: Tracing the circulation to and from the placenta, a drop of blood travels in the fetus from the left ventricle to the aorta, to a common iliac artery, to an internal iliac artery, to an umbilical artery, to capillaries in the placenta, to the ductus venosus, to a hepatic vein, to the inferior vena cava, to the right atrium, to the foramen ovale, to the left atrium, and to the left ventricle. (a) umbilical vein, (b) ligamentum arteriosum, (c) internal carotid artery, (d) capillaries in the small intestine.arrow_forwardcomplete blockage of this coronary artery results and sudden death because of the large amount of blood it's supplies to the heart:arrow_forward
- Occasionally, either the ductus arteriosus or the foramen ovale stays patent (open) after birth. What functional deficit do both these conditions produce?arrow_forwardUnder normal conditions, pressures in the left and right ventricles are equal during systole. * true falsearrow_forward(a) Explain in your own words why varicose veins are more common in the lower limbs than elsewhere in the body.
