what type of murmur is heard in tetralogy of fallot
Aortic regurge- diastolic decrescendo murmur
what is transposition of the great arteries
the Pulmonary artery and aorta switches place meaning RV pumps blood into the aorta and LV pumps blood into the Pulmonary artery
if the heart in a featus is duct dependant what must you avoid when it comes to treatment and why
Oxygen as the duct will close if excess oxygen is present
