Radiation exposure of the operator during coronary interventions (from the RADIO Study)

Kallinikou, Zacharenia ; Puricel, Serban G. ; Ryckx, Nick ; Togni, Mario ; Baeriswyl, Gerard ; Stauffer, Jean-Christophe ; Cook, Stéphane ; Verdun, Francis R. ; Goy, Jean-Jacques

In: The American Journal of Cardiology, 2016, vol. 118, no. 2, p. 188–194

We sought to compare operator radiation exposure during procedures using right femoral access (RFA), right radial access (RRA), and left radial access (LRA) during coronary angiography (CA) and percutaneous coronary intervention (PCI). Because of an increased incidence of long-term malignancy in interventional cardiologists, operator radiation exposure is of rising concern. This prospective...

Heart rate never lies: interventional cardiologist and Braude’s quote revised

Cook, Stéphane ; Stauffer, Jean-Christophe ; Goy, Jean-Jacques ; Graf, Denis ; Puricel, Serban ; Frobert, Aurélien ; Muller, Olivier ; Togni, Mario ; Arroyo, Diego

In: Open Heart, 2016, vol. 3, no. 1, p. e000373

Background Interventional cardiologists may be immune to stress, allowing them to perform complex percutaneous interventions under pressure.Objectives To assess heart rate (HR) variations as a surrogate marker of stress of interventional cardiologists during percutaneous cardiac procedures and in every-day life.Design This is a single-centre...

Vascular response to everolimus- and biolimus-eluting coronary stents versus everolimus-eluting bioresorbable scaffolds – an optical coherence tomography substudy of the EVERBIO II trial

Kallinikou, Zacharenia ; Arroyo, Diego ; Togni, Mario ; Lehmann, Sonja ; Corpataux, Noé ; Cook, Malica ; Müller, Olivier ; Baeriswyl, Gérard ; Stauffer, Jean-Christophe ; Goy, Jean-Jacques ; Puricel, Serban ; Cook, Stéphane

In: Swiss Medical Weekly, 2016, p. -

QUESTIONS UNDER STUDY: Head-to-head optical coherence tomography (OCT) data comparing metallic stents with bioresorbable vascular scaffolds (BVS) are lacking. This study assessed vascular healing at 9-month follow-up after implantation of everolimus- and biolimus-eluting stents (EES BES) and everolimus-eluting BVS.METHODS: OCT was performed in 74 patients enrolled in the EVERBIO II (NCT01711931)...

Comparison of everolimus-eluting and biolimus-eluting coronary stents with everolimus-eluting bioresorbable scaffold: study protocol of the randomized controlled EVERBIO II trial

Arroyo, Diego ; Togni, Mario ; Puricel, Serban ; Gerard, Baeriswyl ; Sonja, Lehmann ; Corpataux, Noé ; Villeneuve, Hélène ; Boute, Estelle ; Stauffer, Jean-Christophe ; Goy, Jean-Jacques ; Cook, Stéphane

In: Trials, 2014, vol. 15, no. 1, p. 9

Background: Second-generation everolimus-eluting stents (EES) and third generation biolimus-eluting stents (BES) have been shown to be superior to first-generation paclitaxel-eluting stents (PES) and second-generation sirolimus-eluting stents (SES). However, neointimal proliferation and very late stent thrombosis is still an unresolved issue of drug-eluting stent (DES) implantation overall. The...

A randomized comparison of platelet reactivity in patients after treatment with various commercial clopidogrel preparations: The CLO-CLO trial = Étude randomisée comparant la réactivité plaquettaire des patients traités par diverses préparations commerciales de clopidogrel. Étude CLO-CLO

Oberhänsli, Markus ; Lehner, Cédric ; Puricel, Serban ; Lehmann, Sonja ; Togni, Mario ; Stauffer, Jean-Christophe ; Baeriswyl, Gérard ; Goy, Jean-Jacques ; Cook, Stéphane

In: Archives of Cardiovascular Diseases, 2012, vol. 105, no. 11, p. 587–592

BackgroundThe salt linked to the clopidogrel molecule in generic preparations is suspected to affect its clinical efficacy. There is a lack of information about inhibition of platelet reactivity by generic preparations.AimsTo compare the effect of original clopidogrel (clopidogrel bisulphate [Plavix®]), generic clopidogrel preparations (clopidogrel hydrochloride...

Balloon angioplasty using the "grip" scoring balloon for treatment of coronary in-stent restenosis - immediate and 12-month clinical outcomes

Puricel, Serban ; Schoepke, Linus ; Togni, Mario ; Oberhänsli, Markus ; Moschovitis, Aris ; Meier, Bernhard ; Windecker, Stephan ; Cook, Stéphane

In: Cardiovascular Medicine, 2012, vol. 15, no. 12, p. 354–361

Objectives: We sought to determine the efficacy and safety of a scoring balloon for the treatment of in-stent restenosis (ISR). Background: The optimal therapy for ISR is not yet properly established and subject to many discussions. The GRIP™ Balloon (Acrostak, Switzerland) might be of interest for the treatment of certain types of ISR. Methods: Between 2003 and 2009, 157 patients who were...
