INTRODUCTIONCompared to the use of balloon angioplasty alone, endovascular treatment of aortic coarctation in adults with the use of stents has shown favourable results and a reduction in complications.
CASE REPORTA 65-year-old Caucasian woman with a history of coarctation of the aorta presented in December 2007 with chest and shoulder pain associated with significant elevation of troponin I level, and was diagnosed with non-ST-segment elevation myocardial infarction (NSTEMI). She had not been previously told that she needed treatment for coarctation and was thus not on regular follow-up. Her left arm blood pressure was 180/90 mmHg and she had a grade 3 ejection systolic murmur heard over the aortic region, which radiated posteriorly. Lower limb pulses were not palpable. Despite treatment with atenolol 100 mg, losartan 100 mg, frusemide 40 mg and methyldopa 500 mg twice daily, her systolic blood pressure remained persistently elevated.Cardiac catheterisation following this acute presentation showed normal coronaries, but a significant peak-to-peak gradient of 60 mmHg across a highly calcified coarctation site was found.The patient had undergone multiple orthopaedic surgeries on both knees as well as repeated surgeries for iritis, one of which was complicated and required enucleation of the left eye. ABSTRACT Although the treatment of aortic coarctation in adults with the use of stents has shown favourable results and reduced complications, there have been few studies involving elderly patients. We highlight the clinical challenges faced in the management of such patients, with attention to severe calcification at the coarctation site. The midterm results were good in our patient, showing an improvement in blood pressure control and maintenance of stent patency.
