Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: discharge diagnosis: aortic coarctation. history of present illness: this infant was born at 38 and 2/7 weeks gestation to a 23 year-old gravida 3 para woman whose past medical history and obstetric histories were unremarkable. prenatal screens were blood group o positive, antibody test negative, hepatitis b surface antigen negative, rpr negative. the pregnancy was uncomplicated until obstetric ultrasound and subsequent fetal echocardiogram at one week prior to delivery showed several abnormalities, including a hypoplastic mitral valve and aortic valve, slightly hypoplastic left ventricular and a hypoplastic aortic isthmus with retrograde flow from a posterior descending coronary artery as well as a suspected coarctation of the aorta. labor was induced due to these abnormalities. there was no prolonged rupture of membranes or maternal intrapartum fever and the amniotic fluid was clear. she proceeded to a vaginal delivery. the infant was vigorous at delivery and required no resuscitation other then bulb suctioning and tactile stimulation. apgar scores were 8 at one minute and 9 at five minutes. the birth weight was 3420 grams. the infant was transferred to the neonatal intensive care unit for further investigations in light of the antenatal findings. while in the intensive care unit the following issues were of concern: 1. respiratory: the infant has remained well saturated in room air with no respiratory distress since admission. 2. cardiovascular: with the exception of a soft 1/6 systolic ejection murmur at the upper left sternal border, the cardiac examination was unremarkable. there was no evidence of compromised cardiac output, cardiac failure or shunt physiology. blood pressure was normal in all four extremities and femoral pulses were strong. in light of the antenatal findings, and after consultation with the cardiology service, prostaglandin was started at 0.025 mcg per kilogram per minute, which the infant tolerated well. 3. fluids, electrolytes and nutrition: feeds were withheld until cardiac investigations were complete. a peripheral intravenous line was placed and maintenance dextrose solution provided. 4. infectious disease: in light of the absence of sepsis risk factors, investigations or therapy for possible infection were not instituted. the infant did receive the neonatal erythromycin for prophylaxis of ophthalmia neonatorum. 5. neurological: the infant remained neurologically normal throughout his course. summary: in summary, this term infant with prenatally diagnosed hypoplastic left heart variant and possible coarctation presents without symptoms in the neonatal period. prostaglandin has been started and he will be transferred to the cardiac intensive care unit at for further investigation and definitive management. his parents have been fully updated prior to the delivery and after birth. , m.d. dictated by: medquist36 d: 07:47 t: 08:27 job#: procedure: enteral infusion of concentrated nutritional substances diagnoses: single liveborn, born in hospital, delivered without mention of cesarean section other specified congenital anomalies of heart coarctation of aorta (preductal) (postductal) 

Answer: The patient is high likely exposed to
