5. CONCLUSION
In conclusion, LV function tends to decrease in cases complicated by hypertension despite successful treatment of coarctation. LV structural and functional change in response to CoA do exist and tend to normalize after correction of the obstruction, although not completely. Hypertension is an important complication in these patients and its treatment and follow-up is important. In addition, further research is needed to propose the most accurate parameter for function and prognosis.
