ABSTRACT: Background:
Coarctation of aorta is a common congenital cardiac malformation; controversy has
surrounded the use of balloon angioplasty for native coarctation of aorta as the
primary treatment for patients with various ages with coarctation. Aim: This study
aimed to assess the long term outcome of balloon angioplasty especially concerning
aneurysm formation. Patients and Methods: A case series (case follow-up) study was carried out on a total of 50 patients
(31 male and 19 female) with native coarctation of aorta aged 1 - 21 years of
age who were treated with balloon angioplasty for more than 1 year at the time of
follow up evaluation in surgical specialty hospital/cardiac center in Erbil
Iraq. They were
recalled and subjected to detail clinical examination, body weight, height, blood
pressure measurements. Radiographic, Echo
Doppler data, CT angiography were obtained. CT angiography was done for 34 patients. Full echocardiographic evaluation was done in
follow up visits. Results: There was a significant reduction in the peak
instantaneous pressure gradient across the coarctated area by Doppler echocardiogram gradient before
balloon angioplasty and at the follow up
visit from 56.92 ± 14.6 mmHg to 30.68 ± 16.89, P = 0.00. Six cases
of total 50 patients had evidence of diastolic runoff pattern by Doppler
Echcardiogram. While the only 6 of total 34 cases had the report of CT angiography
that documented aneurysm formation (12%). Conclusions: Balloon angioplasty of native
aortic coarctation can be performed
safely and effectively with good immediate outcome. Furthermore, it offers
satisfactory long-term
results with low incidence of persisting restenosis, hypertension and aneurysm
formation.
