Case Report: Surgical resolution of aortic coarctation in pediatric patient

Abstract

BACKGROUND: Coarctation of the aorta is a congenital heart disease with an incidence of 4 per 10 000 live births, it may or may not be associated with patent ductus arteriosus as well as other malformations. It is usually asymptomatic and diagnosed by its classic signs such as; arterial pressure gradient between extremities, reduced pulses in the lower extremities, arterial hypertension in the upper extremities or, in severe cases, left heart failure. Its resolution can be percutaneous or surgical, depending on the patient’s age and the characteristics of the defect. CASE REPORTS: A 6-year-old male patient, asymptomatic, with suspected aortic coarctation, due to a difference between arterial pressures in the upper and lower limbs, lower limbs with reduced pulses, and a systolic murmur in the aortic focus. An echocardiogram was requested, which reported a bicuspid aortic valve with raphe, mild regurgitation, and coarctation of the aorta; CT angiography showed coarctation of the juxtaductal aorta; cardiac catheterization showed almost no passage of contrast through the defect, so surgical treatment was scheduled. EVOLUTION: Surgical correction was performed by coartectomy with end-to-end anastomosis and closure of the ductus arteriosus. After the intervention, a relevant improvement in the pressure gradient between the extremities was observed. In the postoperative period the patient presented hypertension, that we managed to control, the patient progressed favorably and was discharged after 4 days without antihypertensive treatment. CONCLUSION: Life expectancy in patients who underwent surgery to correct a congenital heart disease is higher than in those who don’t, so timely diagnosis is an important tool to improve life quality and life expectancy.
