ABSTRACT
Coarctation of aorta(CoA) has been recognized to be cured by corrective operation, so many clinicians have discontinued follow-up early. However, high incidences of cardiovascular morbidity and mortality, of which causes have been known as persistent resting hypertension and exercise-induced hypertension after corrective operation, have been reported during long-term follow-up. And left ventricular mass increase associated with persistent resting hypertension and exercise-induced hypertension has been known as an independent risk factor of cardiovascular disease. So, even for successfully operated CoA patients, increased left ventricular mass as well as resting hypertension and exercise-induced hypertension must be detected early and normalized through persistent observation to adulthood.
