A novel paclitaxel-eluting porous carbon-carbon nanoparticle coated, nonpolymeric cobalt-chromium stent: evaluation in a porcine model.
We aimed to evaluate the response of porcine coronary arteries to a novel paclitaxel-eluting porous carbon-carbon nanoparticle coated, nonpolymeric cobalt chromium stent. ⋯ This preclinical evaluation demonstrates the safety and efficacy of a novel cobalt chromium stent with a carbon-carbon coating and low and medium doses of paclitaxel.

Real-time MRI guided atrial septal puncture and balloon septostomy in swine.
Cardiac perforation during atrial septal puncture (ASP) might be avoided by improved image guidance. X-ray fluoroscopy (XRF), which guides ASP, visualizes tissue poorly and does not convey depth information. Ultrasound is limited by device shadows and constrained imaging windows. ⋯ Septostomy achieved a mean left to right shunt ratio of 1.3:1 in these healthy animals. Interactive rtMRI permits rapid transcatheter ASP and BAS in swine. Further technical development may enable novel applications.

Case ReportsDifficult retrieval of the EPI Filterwire with a 5 French FR4 coronary catheter following carotid stenting.
Carotid angioplasty and stenting with an embolic protection device is emerging as a reasonable alternative to carotid endarterectomy in high-risk patients. The deployment and retrieval of these devices, however, can be problematic. We describe a case where a 5 Fr FR4 coronary catheter was used to retrieve an EPI Filterwire device following carotid stenting.

The impact of interventional cardiology for the management of adults with congenital heart defects.
The objective of this study is to assess the impact of interventional cardiology procedures for the management of ACHD. The interventional approach to the management of CHD in the adult population is becoming increasingly recognized as the preferred treatment option for a wide number of congenital cardiac conditions. The files of all consecutive patients over 18 years of age who were hospitalized in our department from January 2000 to December 2004 were reviewed. ⋯ A trivial residual shunt was detected in only 5% of the patients who had a 6-month follow-up after VSD closure; no residual shunt was found after PDA embolization during the 12-month follow-up. In conclusion, we believe that the interventional approach is a safe and successful treatment option for a wide number of congenital cardiac conditions. The increasing use of catheter interventions for these patients will be responsible for an increase of complex cases in surgery.

Multicenter Study Comparative StudyComparison of sirolimus-eluting stent, paclitaxel-eluting stent, and bare metal stent in the treatment of long coronary lesions.
This study compared the efficacy of the sirolimus-eluting stent (SES), the paclitaxel-eluting stent (PES), and the bare metal stent (BMS) for long coronary lesions. ⋯ The use of DESs for long coronary lesions appears to be safe and more effective than the use of BMSs in terms of restenosis and adverse clinical events. SES use was associated with lower late luminal loss and a lower angiographic restenosis rate compared with PES use.
