Three-months optical coherence tomography analysis of a biodegradable polymer, sirolimus-eluting stent.

Objective: We aimed to assess early neointimal healing by optical coherence tomography (OCT) 3 months after implantation of the ultrathin Orsiro® sirolimus-eluting stent with biodegradable polymer.

Background: New generations of drug-eluting stents with biodegradable polymer have been developed to avoid the continued vascular irritation of durable polymers.

Methods: In this prospective, open-label study, 34 patients received an Orsiro® sirolimus-eluting stent with biodegradable polymer.

A randomized trial of bifurcation stenting technique in chronic total occlusions percutaneous coronary intervention.

Background: The optimal strategy to treat bifurcation lesions (BFLs) in a percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) remains unknown.

Aims: We sought to assess whether T-provisional or mini-crush is appropriate for BFLs within CTO vessels.

Patients And Methods: From January 2011 to December 2013, patients who underwent successful CTO guidewire crossing and with a BFL within the CTO target vessel were enrolled prospectively and assigned randomly to either T-provisional stenting or the mini-crush technique for BFL treatment.

Mid-term outcome of biolimus-eluting stents with biodegradable polymer: results from a multinational prospective 'all-comers' registry.

Background: The Nobori biolimus-eluting stent (BES) is a biodegradable polymer drug-eluting stent (DES). Several studies have shown its noninferiority in comparison with durable polymer DES.

Aim: We sought to investigate the efficacy and the safety of Nobori BES in an all-comer population undergoing a percutaneous coronary intervention.

Incidence of atrial fibrillation after percutaneous closure of patent foramen ovale and small atrial septal defects in patients presenting with cryptogenic stroke.

Objective: The occurrence of atrial fibrillation after percutaneous closure of a patent foramen ovale for cryptogenic stroke has been reported in a variable percentage of patients. However, its precise incidence and mechanism are presently unclear and remain to be elucidated.

Design: Prospective follow-up study.

The role of the sizing balloon in selection of the patent foramen ovale closure device size.

Objectives: To find a correlation between the patent foramen ovale (PFO) size measured by the sizing balloon and the appropriate closure device size.

Methods: The PFO of 57 patients was closed using a sizing balloon. A mathematical model was introduced to relate the PFO balloon waist diameter to the closure device size based on the PFO transformation from a slit-like to a circular form during balloon inflation.
