A case of early development of giant coronary artery aneurysms after drug-eluting stents implantation: An unpredictable menace

Abstract

Development of coronary artery aneurysm (CAA) after implantation of drug-eluting stent is occasionally observed. We present a case of a 67-year-old man who underwent everolimus-eluting stent (EES) implantation in right coronary artery (RCA) for inferior wall myocardial infarction, and thereafter, giant CAAs were developed in the vessel of stent deployment, within 2 months. However, the patient was managed with coronary artery bypass grafting (CABG). On follow-up, the patient’s condition was stable. To the best of our knowledge, we report the first case of occurrence of EES-associated giant CAAs in RCA subsequently treated with CABG.

Very Early Coronary Artery Aneurysm After Primary Percutaneous Coronary Intervention in Patient With HIV and Thrombophilia

“…The formation of a CAA after PCI is related to some factors not present in the context of CAAs not treated percutaneously. The emergence of aneurysms has been described from 3 days up to 4 years [1, 2, 4].…”

Coronary artery aneurysm: A review

“…Lastly, CAA may complicate coronary angioplasty with stent implantation[ 38 - 40 ]. Aneurysmal formation was observed with bare metal stents, drug eluting stents and biodegradable stents[ 38 - 40 ].…”

“…Lastly, CAA may complicate coronary angioplasty with stent implantation[ 38 - 40 ]. Aneurysmal formation was observed with bare metal stents, drug eluting stents and biodegradable stents[ 38 - 40 ]. Coronary dissection, oversizing, stent malapposition, high pressure balloons and local wall injury are the main mechanisms associated to stent-related CAA[ 41 , 42 ].…”

Acute myocardial infarction in a patient with coronary artery aneurysm

“…Dok se osnovni a ološki rocesi razlikuju kod svakog e iološkog fak ora, čini se da u osnovi doprinose slabljenju zida krvnog suda i dilatacija [2]. AKA su najčešće asim oma ske, ali se ponekad manifestuju kao angina pektoris, iznenadnom smrću, formiranjem fis ula, tamponadom perikarda ili kongestivnom srčanom insuficijencijom, mada je eško u vrdi i da li je to posledica AKA ili je u osnovi etiopatogeneze stenoza i/ili tromboza koronarne artereije ili infarkt miokarda [5]. Nelečene ili nedijagnos ikovane aneurizme mogu se komplikovati rupturom, tromboembolijskim fenomenima, ređe fis ulizacijom u jednu od srčani šu ljina, š o sve može doves i u ojedinim slučajevima do am onade srca, srčanim zas ojem ili iznenadnom smrću .…”
