Early Natural History of Spontaneous Coronary Artery Dissection
Original Research | By Waterbury TM, Tweet MS, Hayes SN et al.
BACKGROUND - Risks and mechanisms of extension of conservatively managed spontaneous coronary artery dissection (SCAD) remain incompletely understood. Study objectives were to (1) evaluate mechanisms of early SCAD evolution through serial angiographic analysis, and (2) determine predictors of early SCAD progression. METHODS AND RESULTS - Retrospective registry study of patients with SC...
Combined use of OCT and IVUS in spontaneous coronary artery dissection
Original Research | By Choi KH, Song YB, Hahn JY et al.
OBJECTIVES - This study sought to determine whether intravascular ultrasound (IVUS) guidance compared with angiographic guidance reduces long-term risk of cardiac death in patients undergoing complex percutaneous coronary intervention (PCI). BACKGROUND - Although IVUS is a useful tool for accurate assessment of lesion profiles and optimal stent implantation, there are limited data on long-term clinical...

Coronary artery bifurcation lesions comprise approximately 15-20% of all percutaneous coronary interventions (PCI) and constitute a complex lesion subgroup. Intravascular optical coherence tomography (OCT) is a promising adjunctive tool for guiding coronary bifurcation with its unrivalled high resolution. Compared to angiography, intravascular OCT has a clear advantage in that it depicts ostial lesion(s) in bifurcation without the misleading two-dimen...

OBJECTIVES- The randomized clinical VANISH (Impact of Vascular Reparative Therapy on Vasomotor Function and Myocardial Perfusion: A Randomized [15O]H2O PET/CT Study) trial was conducted to assess quantitative myocardial blood flow (MBF) during resting, hyperemia, and cold pressor testing (CPT) with positron emission tomographic perfusion imaging after the implantation of a bioresorbable everolimus-eluting scaffold comp...
Clinical Trial | By Sotomi Y, Onuma Y, Dijkstra J et al.
AIMS - The natural course of post-procedural incomplete strut apposition (ISA) after the implantation of bioresorbable scaffolds (BVS) remains unknown. The purpose of the present study was to evaluate the fate of post-procedural ISA after everolimus-eluting Absorb BVS in comparison with the second-generation everolimus-eluting cobalt chromium stent (CoCr-EES). METHODS AND RESULTS - F...

AIMS - We sought to compare vascular healing with bioresorbable everolimus-eluting vascular scaffolds (BVS) and drug-eluting stents with bioabsorbable polymers (BP-DES) at six and 12 months both implanted in the same patients. METHODS AND RESULTS - This was a multicentre and prospective study including patients with at least two comparable lesions to treat. In every patient both BVS and BP-DE...
