Case ReportsProtamine usage following implantation of drug-eluting stents: a word of caution.
The treatment of hemorrhagic complications of percutaneous interventions with protamine is an accepted practice. Concerns exist about the increased thrombo-genicity of drug-eluting stents. We report two cases of acute stent thrombosis following drug-eluting stent implantation related to protamine administration.

Case ReportsCarotid sheath rescue with a distal filter retrieval catheter.
Sheath placement prior to carotid artery stenting is usually uncomplicated, and provides sufficient support for the procedure. In certain patients, especially those with unfavorable arch anatomy, tortuous vessels, and heavily calcified lesions, the sheath backs out into the aortic arch with compromise of wire and embolic protection device (EPD) position, and risk of "dragging" the EPD back through the lesion. ⋯ Use of the filter retrieval catheter as a "body" to retrack the sheath but not recapturing the deployed filter is a useful technique, since the equipment is already available. This avoided the need to pull a retrieved filter through a severe undilated carotid stenosis, reducing the amount of manipulations needed to reposition the sheath and thus reducing the risk of embolic events.

Multicenter Study Clinical TrialOutcome after percutaneous closure of a patent foramen ovale using the Intrasept device: a multi-centre study.
This multi-centre study reports safety and efficacy of percutaneous patent foramen ovale (PFO) closure, using the fourth generation Intrasept device. ⋯ This multi-centre study suggests that percutaneous closure of a symptomatic PFO with the fourth generation Intrasept device is safe and might be effective to prevent the recurrence of paradoxical thrombo-embolic events.

Comparative StudySafety and effectiveness of drug eluting stent in patients with ST elevation myocardial infarction undergoing primary angioplasty.
Drug eluting stents (DES) have recently been proven to further reduce restenosis and revascularization rate in comparison to bare metal stents in elective procedures. Most early DES trials did not include patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation MI, because these patients tend to have lower restenosis rates than other patient groups and delayed endothelization of these stents raises concern about a possible increase of thrombotic complications in the setting of STEMI. ⋯ Utilization of DES in the setting of primary PCI for STEMI, in our "real world," was safe and improved the 3-year clinical outcome compared with BMS reducing the need of TVR.
