Randomized Controlled Trial Multicenter Study Comparative StudyRandomized evaluation of two drug-eluting stents with identical metallic platform and biodegradable polymer but different agents (paclitaxel or sirolimus) compared against bare stents: 1-year results of the PAINT trial.
We tested two novel drug-eluting stents (DES), covered with a biodegradable-polymer carrier and releasing paclitaxel or sirolimus, which were compared against a bare metal stent (primary objective). The DES differed by the drug, but were identical otherwise, allowing to compare the anti-restenosis effects of sirolimus versus paclitaxel (secondary objective). ⋯ Both novel DES were effective in reducing neointimal hyperplasia and 1-year re-intervention, compared to bare metal stents. Our findings also suggest that sirolimus is more effective than paclitaxel in reducing angiographic neointima, although this effect was not associated with better clinical outcomes.

Case ReportsTransfemoral percutaneous removal of a knotted Swan-Ganz catheter.
Intracardiac knotting of balloon-tipped flow-directed catheters during a heart catheterization procedure represents a rare but serious complication. In case that such an event occurs, leading to inability to remove the catheter, various different methods have been described to solve the problem, varying from the least invasive to open heart surgery. ⋯ We describe the successful nonsurgical removal of a Swan-Ganz catheter, after the formation of a large double knot, during a right heart catheterization performed without fluoroscopic guidance in the intensive care unit. This technique could serve as a last resort in cases that surgical removal seems inevitable due to size-related inapplicability of other nonsurgical methods.
