“…The utilization of covered stents is faster, and more effective, and is considered to be the gold standard in the management of coronary perforation [8]. The incidence of subacute thrombosis and restenosis in the covered stents is relatively higher than in the conventional coronary stents (10.3% versus 3.4%).…”

“…The incidence of subacute thrombosis and restenosis in the covered stents is relatively higher than in the conventional coronary stents (10.3% versus 3.4%). This problem may be related to delayed endothelialization and increases susceptibility to thrombus formation [8], and long-term dual antiplatelet therapy is recommended [9]. According to previous studies, in-stent restenosis occurs with a frequency of approximately 30% within the first six months after implantation, and in most cases was related to edge stenosis (29.8%) [10].…”

International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties.Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations. IJCRI publishes ABSTRACTAn 87-year-old Asian male experienced progressive shortness of breath for two days. He presented symptoms and signs of decompens-ated heart failure and was diagnosed as non ST-segment elevation myocardial infarction, killip III. Coronary intervention was performed for chronic total occlusion of left anterior descend-ing artery. Unfortunately, coronary perforation happened during balloon anchoring after rotational atherectomy. Rotational atherectomy may be not related to perforation, but causes vessel wall more fragile after disruption of the arc of calcification. Even if balloon anchoring was performed at low pressure, we need keep in mind that it still could result in a terrible coronary perforation after debulking techniques. Covered stents for emergency implantation in case of coronary perforation must be an obligatory inventory of catheterization laboratories. It is an effective alternative that can be used to seal a major coronary perforation.(This page in not part of the published article.)

We present the case of a 58-year-old male with coronary artery disease and a significant stenosis of the left circumflex artery that was preceded by a coronary aneurysm. The stenosis and aneurysm were treated successfully with a coronary stent graft. The patient subsequently developed in-stent restenosis (ISR). The ISR was then successfully treated with a paclitaxel-eluting stent (PES). The patient has been followed clinically for 4-6 years without recurrence of his anginal symptoms. This is the first description in the literature of which we are aware of the successful treatment of an ISR of a coronary stent graft with a PES with persistent long-term clinical effectiveness.The patient is a 58-year-old male with a long history of coronary artery disease. He had undergone multiple percutaneous coronary interventions in both the right coronary artery (RCA) and proximal left anterior descending artery (LAD) with bare metal stents. In December 2003 during follow up for angina-type chest discomfort, a perfusion study demonstrated inferior wall reversibility. The patient underwent cardiac catheterization which demonstrated total occlusion of the proximal RCA which was previously stented from the ostium to the distal vessel and now filled from * Corresponding author.

The left-to-right collaterals are well developed from the LAD and the left circumflex artery (LCA) all the way up to the RCA distal stents. However, there were also extensive bridging collaterals with very small caliber side-branches at the occlusion cap. Eventually, the bridging collaterals form a very thin column of faint contrast filling all the way down to the distal stents. A new 1 cm aneurysmal segment in the midportion of the LCA with a 50% stenosis just before the aneurysmal segment followed by an 80% stenotic hazy lesion at the distal portion of the aneurysm ''wrap-around-aneurysmal-candy'' (Fig. 1A), followed by a trifurcating obtuse marginal branch (Fig. 1A).The patient was seen in the clinic two weeks after his diagnostic angiogram. Options included percutaneous intervention to re-canalize the RCA or treatment of the aneurysm with both the proximal and distal portion lesions with a covered stent. Alternatively, bypass surgery was an

“…However, these materials suffers from certain degree of thrombogenicity, poor compliance and low flexibility, hence are not favourable for small calibre coronary covered stent membrane 10 . We have developed and patented a nanocomposite material based on polyhedral oligomeric silsesquioxane and poly(carbonate-urea) urethane (POSS-PCU).…”
