    1. Scaffold thrombosis following implantation of the Absorb Bvs in routine clinical practice: Insight into possible mechanisms from optical coherence tomography

      Scaffold thrombosis following implantation of the Absorb Bvs in routine clinical practice: Insight into possible mechanisms from optical coherence tomography

      Objectives To identify potential underlying mechanisms of early and (very) late scaffold thrombosis (ScT) by optical coherence tomography (OCT), in a frame-by-frame analysis. Background The absorb scaffold is associated with an increased risk of ScT compared with metallic stents. Several potential causes of bioresorbable ScT have been identified, however the precise etiology still remains unclear. Methods Between February 2013 and February 2016, 13 patients presenting with definite ScT underwent OCT imaging. After guidewire passage or balloon inflations, OCT images were acquired. Pullbacks were assessed offline at each 1 mm longitudinal interval within the treated segment and the 5 mm segments ...

    2. Treatment of coronary bifurcation lesions with the Absorb bioresorbable vascular scaffold in combination with the Tryton dedicated coronary bifurcation stent: evaluation using two- and three-dimensional optical coherence tomography

      Treatment of coronary bifurcation lesions with the Absorb bioresorbable vascular scaffold in combination with the Tryton dedicated coronary bifurcation stent: evaluation using two- and three-dimensional optical coherence tomography

      Aims: The Tryton bifurcation stent has been developed to improve clinical outcomes after treatment of bifurcation lesions. Limited data are available on the use of the Absorb bioresorbable vascular scaffold (BVS) in bifurcation lesions with side branches >2 mm. We present here the acute procedural results and midterm clinical follow-up of the first-in-man combined use of the Tryton stent and the Absorb scaffold for the treatment of complex bifurcation lesions. Methods and results: Ten patients treated with the Tryton stent in combination with Absorb BVS were included in the current report. Offline two- and three-dimensional optical coherence tomography (OCT) analyses ...

    3. Side branch healing patterns of the Tryton dedicated bifurcation stent: a 1-year optical coherence tomography follow-up study

      Side branch healing patterns of the Tryton dedicated bifurcation stent: a 1-year optical coherence tomography follow-up study

      The bare-metal Tryton Side Branch (SB) Stent™ (Tryton Medical, Durham, NC, USA) is used with a drug-eluting stent (DES) in the main branch (MB) to treat bifurcation lesions. It is argued that a drug-eluting Tryton-version is needed to improve clinical outcomes, although previous registries have shown good clinical results. More insights in neo-intimal hyperplasia (NIH) growth patterns of the Tryton treatment strategy are needed to decide if and where to drug-coat the stent. Ten patients returned for follow-up angiography (mean follow-up time 393 ± 103 days) and optical coherence tomography (OCT) pullbacks from the MB were obtained in all patients and ...

    4. Three-dimensional optical coherence tomography evaluation of a left main bifurcation lesion treated with ABSORB® bioresorbable vascular scaffold including fenestration and dilatation of the side branch - Corrected Proof

      Three-dimensional optical coherence tomography evaluation of a left main bifurcation lesion treated with ABSORB® bioresorbable vascular scaffold including fenestration and dilatation of the side branch - Corrected Proof

      Previous trials on the ABSORB (Abbott Vascular, Santa Clara, USA) everolimus-eluting bioresorbable vascular scaffold (BVS) were predominated by relatively low-risk lesions, excluding patients with left main coronary artery (LMCA) lesions and bifurcation lesions involving side branches >2mm . Little is known about the safety and feasibility of fenestration and dilation of the side branch ostium after BVS placement .
