Enhanced Aortic Pressure Wave Reflection in Patients with Aortic Coarctation after Aortic Arch Repair

Abstract

In patients with aortic coarctation after successful aortic arch repair, it is well known that early-onset cardiovascular diseases can develop. We studied the pressure waveform in patients after aortic arch repair focusing on a pressure wave reflection. In patients after aortic arch repair, the repaired portion generates a new reflected pressure wave. As a result, the newly generated pressure wave causes aortic pressure augmentation, loss of pressure amplification, and left ventricular hypertrophy with fibrosis. Balloon dilatation of the aortic arch may also generate a new pressure wave reflection. In patients with aortic coarctation after aortic arch repair, the reconstructed site generates a new pressure wave reflection. This could be one of the causes of their future cardiovascular diseases.
