Introduction
Overview
Overview
Diagnosis can be done after 18 weeks gestation using an ultrasound. However, if it is not diagnosed in utero, cyanosis of the newborn (blue baby) should immediately indicate that there is a problem with the cardiovascular system.
Post natal d-TGA
Post natal d-TGA
- Most of the time, diagnosis can be done after 18 weeks gestation using an ultrasound. However, if it is not diagnosed in utero, cyanosis of the newborn (blue baby) should immediately indicate that there is a problem with the cardiovascular system.
- After birth, the blood in the pulmonary artery will flow into the lungs, which have been expanded with the first breathing presenting less resistance, and the ductus arteriosus will close. Sometimes shunts will fail to close after birth and will result in a patent foramen ovale PFO and patent ductus arteriosus PDA. They may occur independently, or in combination with one another, or with d-TGA or other heart and/or general defects.
