Recent analyses have suggested that implantation of drug-eluting stents （DES） is associated with a higher rate of very late stent thrombosis when compared with bare metal stents （BMS）. According to Academic Research Consortium （ARC） definition,1 very late stent thrombosis refers to events occurring more than 12 months following stent placement. This complication is evident with sirolimus-eluting stents （SES） as well as polymer-based paclitaxel-eluting stents （PES）,

Although catheterization of the subclavian vein is a common procedure, it might be associated with life-threatening complications including accidental cannulation of subclavian artery. Rash sheath removal could result in fatal hemorrhage. We report a case of inadvertent 6F sheath cannulation of the right subclavian artery during a radiofrequency catheter ablation procedure and successful repair of the cannulation by Angio-Seal STS plus （St. Jude Medical, St. Paul, MN, US）, a collagen-base vascular closure device.

Aortico-cameral tunnel is a rare congenital cardiac .anomaly, which arises from the right coronary sinus and enters the left ventricle, occasionally the right ventricle and right atrium. However, more than one tunnel are seldom seen simultaneously in one patient. Here we present a case of multiple aortico-cameral tunnels associated with the bicuspid aortic valve in a 63-year-old man.

The persistent epidemic of human mpox, caused by mpox virus (MPXV), raises concerns about the future spread ofMPXV and other poxviruses. MPXV is a typical zoonotic virus which can infect human and cause smallpox-likesymptoms. MPXV belongs to the Poxviridae family, which has a relatively broad host range from arthropods tovertebrates. Cross-species transmission of poxviruses among different hosts has been frequently reported andresulted in numerous epidemics. Poxviruses have a complex linear double-strand DNA genome that encodeshundreds of proteins. Genes related to the host range of poxvirus are called host range genes (HRGs). This reviewbriefly introduces the taxonomy, phylogeny and hosts of poxviruses, and then comprehensively summarizes thecurrent knowledge about the cross-species transmission of poxviruses. In particular, the HRGs of poxvirus aredescribed and their impacts on viral host range are discussed in depth. We hope that this review will provide acomprehensive perspective about the current progress of researches on cross-species transmission and HRGvariation of poxviruses, serving as a valuable reference for academic studies and disease control in the future.

Iatrogenic coronary artery fistula （ICAF） is a rare .complication and could happen during endomyocardialbiopsy, open heart surgery or percutaneous coronary intervention. The treatment of ICAF is not well established and is dependent upon the patient＇s haemodynamic situation. Here we report a case of spontaneous resolution of ICAF during such angioplasty.
