Technique of interventional repair in adult aortic coarctation

Abstract

Surgical treatment of aortic coarctation has increased life expectancy and reduced mortality. Unfortunately, the average lifespan after repair remains only 35 to 50 years, and significant morbidity persists as a result of aneurysm formation, hypertension, accelerated coronary disease, and stroke. Follow-up studies have revealed restenosis rates of 30% and persistent hypertension at rest and during exercise, sometimes with compromised cardiac function. The less invasive nature of nonsurgical repair using transcatheter therapies has led to balloon angioplasty and, recently, stent implantation as an emerging concept for the treatment of aortic coarctation. This review focuses on advances in the management, current indication, and techniques of interventional repair in aortic coarctation.
