Interventional Traps in Ectatic Coronary Arteries: A Case Report
Coronary artery ectasia or aneurysms are dilatation of an arterial segment to a diameter at least 1.5 times that of the adjacent normal. Blood flow through such arteries is disturbed and turbulent, which, with the activation of endothelium, leads to chronic thrombosis in the blood vessel wall. Pe...

| Summary: | Coronary artery ectasia or aneurysms are dilatation of an arterial segment to a diameter
at least 1.5 times that of the adjacent normal. Blood flow through such arteries is disturbed and
turbulent, which, with the activation of endothelium, leads to chronic thrombosis in the blood vessel wall.
Percutaneous coronary interventions in ectatic / aneurysmal vessels carry a high risk of complications,
primarily a “no-reflow” phenomenon. No-reflow is common in patients with acute coronary syndrome,
especially ST elevation myocardial infarction (STEMI). In this article, we present the occurrence of the
no-reflow phenomenon in a stable patient undergoing percutaneous intervention due to a significant
stenosis of the aneurysmally altered right coronary artery. Despite the rapid placement and optimization
of stents and the applied drug therapy combined with thromboaspiration periprocedurally, it was not
possible to establish TIMI 3 flow. However, after the initial failure and development of periprocedural
STEMI, the patient was successfully stabilized with unexpectedly good recovery of infarcted myocardial
function. Control coronarography 6 weeks after the initial event confirmed a proper stent patency with
normal TIMI 3 flow. |
