“…Treatment of CAAs with covered stents has been reported in several case reports, however there is limited evidence available on the effectiveness and safety of this interventional practice (14). Burzotta et al suggested use of the selfexpandable Symbiot PTFE-covered stent for percutaneous treatment of a large coronary aneurysms (15).…”

Introduction. Coronary artery aneurysms are rare disorders, especially left main coronary artery aneurysm. In literature there are number of reported cases with coronary artery aneurysms, various localization, size, clinical presentation and way of treatment. There is no unique consensus about the most adequate treatment in these patients; surgery is still preferable, although there are some new experiences of percutaneous treatment. The decision is made for each patient individually. We report a case of giant left main coronary artery aneurysm, with acute coronary syndrome and heart failure presentation, surgically treated. Case report. A 66-year-old female patient was admitted to the Emergency Department of our Clinic due to chest pain and dyspnea. Acute non-STEMI myocardial infarction of anterolateral localization was diagnosed (CK max 1,111, troponin T 3.754) complicated with acute heart failure. Heart catheterization and coronary angiography revealed a giant saccular, 3.5 x 3.5 mm left main coronary artery aneurysm full with thrombi, compressing the proximal segments of left anterior descending (LAD) and circumflex artery (Cx). Conclusion. Giant left main coronary artery aneurysms are rare pathologic finding and there are no established principles for treatment. Although, percutaneous way of treatment is now available in selected cases, surgical approach is still preferred for these patients.

“… 1 PK Papyrus-covered stents are reportedly useful for coronary artery perforation and CAAs, despite higher cardiovascular event rates, including stent thrombosis and restenosis, in selected cases. 2 In cases requiring PK Papyrus-covered stent implantation, IVUS and OFDI have varying capabilities in evaluating outer (vessel)/inner (luminal) conditions, which may help clarify the appropriate management for these patients. 3 …”

“…To solve the problem of restenosis, burying a covered stent under a drug-eluting stent has been proposed [13][14][15]. Another strategy of inhibiting edge restenosis is the implantation of a longer drug-eluting stent prior to covered stent deployment or an overlapping implantation of covered stents with drug-eluting stents at the edges [15][16][17]. Yet another solution is a double or triple stent technique, wherein a 'coronary flow diverter' is created by the deployment of two/three completely overlapping drug-eluting coronary stents [18,19].…”

Background: Coronary aneurysms are an infrequent finding in diagnostic angiography, with a reported incidence of 0.35–0.7% in the largest contemporary registries. At least half of them have an atherosclerotic etiology and as such they are often diagnosed in the setting of acute coronary syndrome. The wiring of a thrombosed aneurysm is a difficult task and after successful recanalization, the operator has to decide on the optimal method of aneurysm exclusion. Covered stents are commonly deployed, but their use involves the risk of delivery failure as well as device dislodgement and loss due to their stiffness and size. Moreover, proper stent sizing and apposition is difficult in the case of thrombosed aneurysms. Case presentation: We present a case of coronary aneurysm recanalization and exclusion with a covered stent, with a postdilation-induced stent foreshortening. Due to the subsequent stent migration into the aneurysm sac, its repositioning was attempted. The pitfalls of coronary aneurysm stenting and neurointerventional techniques of prolapsed device realignment are discussed. Conclusions: An adequate landing zone is of the utmost importance in aneurysm exclusion with covered stents. In the case of a short stent anchoring in the normal vessel, another covered or conventional stent should be deployed to mitigate the risk of the device migration.
