Coronary Artery Bypass Grafting or Fractional Flow Reserve–Guided Percutaneous Coronary Intervention in Diabetic Patients With Multivessel Disease

Giuseppe Di Gioia, Nina Soto Flores, Danilo Franco, Iginio Colaiori, Jeroen Sonck, Carlo Gigante, Monika Kodeboina, Jozef Bartunek, Marc Vanderheyden, Frank Van Praet, Filip Casselman, Ivan Degriek, Bernard Stockman, Emanuele Barbato, Carlos Collet and Bernard De Bruyne

Background: In diabetic patients with multivessel coronary artery disease, coronary artery bypass grafting (CABG) has shown long-term benefits over percutaneous coronary intervention (PCI). Physiology-guided PCI has shown to improve clinical outcomes in multivessel coronary artery disease, though its impact in diabetic patients has never been investigated. We evaluated long-term clinical outcomes of diabetic patients with multivessel coronary artery disease treated with fractional flow reserve (FFR)–guided PCI compared with CABG.

Optical Coherence Tomography Versus Intravascular Ultrasound and Angiography to Guide Percutaneous Coronary Interventions

Daniel Chamié, J. Ribamar Costa Jr, Lucas P. Damiani, Dimytri Siqueira, Sérgio Braga, Ricardo Costa, Henry Seligman, Freddy Brito, Guilherme Barreto, Rodolfo Staico, Fausto Feres, Ricardo Petraco and Alexandre Abizaid

Background: Specific algorithms for use of optical coherence tomography (OCT) to guide percutaneous coronary intervention (PCI) are scarce. Also, the relative benefits of intravascular imaging guidance have not been tested against an optimized angiography-guided PCI strategy. In iSIGHT (Optical Coherence Tomography Versus Intravascular Ultrasound and Angiography to Guide Percutaneous Coronary Interventions), we aimed to investigate whether OCT-guided PCI achieves noninferior stent expansion compared with intravascular ultrasound (IVUS) guidance and if both imaging modalities lead to superior stent expansion compared with an optimized angiography-based strategy.

Primary Results of the EVOLVE Short DAPT Study; Evaluation of 3-Month Dual Antiplatelet Therapy in High Bleeding Risk Patients Treated With a Bioabsorbable Polymer-Coated Everolimus-Eluting Stent

Ajay J. Kirtane, Robert Stoler, Robert Feldman, Franz-Josef Neumann, Loukas Boutis, Naeem Tahirkheli, Ralph Toelg, Islam Othman, Bernardo Stein, James W. Choi, Stephan Windecker, Robert W. Yeh, Harold L. Dauerman, Matthew J. Price, Paul Underwood, Dominic Allocco, Ian Meredith and Dean J. Kereiakes

Background: Prolonged dual antiplatelet therapy (DAPT) after percutaneous coronary intervention is associated with increased bleeding, despite a reduced incidence of ischemic events. The SYNERGY everolimus-eluting stent is a thin-strut platinum-chromium stent that elutes everolimus from a thin abluminal layer of bioabsorbable polymer. These design elements may facilitate rapid endothelialization and enable shorter-duration DAPT.

Comparative Safety of Bioabsorbable Polymer Everolimus-Eluting, Durable Polymer Everolimus-Eluting, and Durable Polymer Zotarolimus-Eluting Stents in Contemporary Clinical Practice

Nadia R. Sutton, Milan Seth, Ryan D. Madder, Devraj Sukul, Simon R. Dixon, Louis A. Cannon and Hitinder S. Gurm

Background: Uncertainty exists over whether stents commonly used for percutaneous coronary intervention have comparable short- and long-term safety. The objective of this study was to determine the outcomes of patients treated with bioabsorbable polymer everolimus-eluting (BP-EES; Synergy, Boston Scientific), durable polymer everolimus-eluting (DP-EES; XIENCE, Abbott Vascular), or durable polymer zotarolimus-eluting (DP-ZES; Resolute, Medtronic) stents in routine clinical practice.

Optical Coherence Tomography Assessment in Patients Treated With Rotational Atherectomy Versus Modified Balloons

Rayyan Hemetsberger, Tommaso Gori, Ralph Toelg, Robert Byrne, Abdelhakim Allali, Mohamed El-Mawardy, Tobias Rheude, Melissa Weissner, Dmitriy S. Sulimov, Derek R. Robinson, Gert Richardt and Mohamed Abdel-Wahab

Background: Percutaneous intervention of calcified coronary lesions often requires lesion preparation with either balloon dilatation or atherectomy. We sought to evaluate the impact of lesion preparation strategy on stent expansion following preparation of severely calcified coronary lesions with modified (cutting/scoring) balloons (MB) versus rotational atherectomy (RA) and to evaluate the impact of calcium burden as assessed by optical coherence tomography (OCT) on acute stent performance.

Patent Ductus Arteriosus Stenting for All Ductal-Dependent Cyanotic Infants

Kanishka Ratnayaka, Stephen J. Nageotte, John W. Moore, Peter W. Guyon, Krishna Bhandari, Rachel L. Weber, Jesse W. Lee, Hyeri You, Danica A. Griffin, Rohit P. Rao, John J. Nigro and Howaida G. El-Said

Background: Ductal-dependent cyanotic newborns require a secure source of pulmonary blood flow. There has been a recent migration to selective ductal (patent ductus arteriosus [PDA]) stenting for some of these children. Universal (nonselective) ductal stenting for all infants with ductal-dependent pulmonary blood flow is controversial. We examine outcomes from a single center with this practice change.
