Daniels,Andrew P. DeFilippis,Affan Haleem Md,Steven M. Hollenberg,James M. Horowitz,Norma Keller,Michael C. Kontos,Patrick R. Lawler,Venu Menon,Thomas S. Metkus,Jason Ng,Ryan Orgel,Christopher B. Overgaard,Jeong Gun Park,Nicholas Phreaner,Robert O. Roswell,Steven P. Schulman,R. Jeffrey Snell,Michael A. Solomon,Bradley Ternus,Wayne Tymchak,Fnu Vikram,David A. Morrow +33 more
TL;DR: In this paper, the authors focused on acute myocardial infarction (AMI) complicated by cardiogenic shock (AMICS) in cardiac intensive care units (CICUs).
Journal ArticleDOI
Demographics, Care Patterns, and Outcomes of Patients Admitted to Cardiac Intensive Care Units: The Critical Care Cardiology Trials Network Prospective North American Multicenter Registry of Cardiac Critical Illness.
Erin A. Bohula,Jason N. Katz,Sean van Diepen,Carlos L. Alviar,Vivian M Baird-Zars,Jeong-Gun Park,Christopher Barnett,Gurjaspreet Bhattal,Gregory W. Barsness,James A. Burke,Paul Cremer,Jennifer Cruz,Lori B. Daniels,Andrew P. DeFilippis,Christopher B. Granger,Steven M. Hollenberg,James M. Horowitz,Norma Keller,Michael C. Kontos,Patrick R.

Solomon,Bradley Ternus,Wayne Tymchak,Fnu Vikram,David A. Morrow +33 more
TL;DR: In a contemporary network of tertiary care CICUs, respiratory failure and shock predominated indications for admission and carried a poor prognosis, while patterns of practice varied considerably between centers, a substantial, low-risk population was identified.
Journal ArticleDOI
Clinical Practice Patterns in Temporary Mechanical Circulatory Support for Shock in the Critical Care Cardiology Trials Network (CCCTN) Registry.
David D. Berg,Christopher Barnett,Benjamin B. Kenigsberg,Alexander Papolos,Carlos L. Alviar,Vivian M Baird-Zars,Gregory W. Barsness,Erin A. Bohula,Joseph Brennan,James A. Burke,Anthony P. Carnicelli,Sunit-Preet Chaudhry,Paul Cremer,Lori B. Daniels,Andrew P. DeFilippis,Daniel A. Gerber,Christopher B. Granger,Steven M. Hollenberg,James M. Horowitz,James D. Gladden,Jason N. Katz,Ellen C. Keeley,Norma Keller,Michael C. Kontos,Patrick R. Lawler,Venu Menon,Thomas S. Metkus,P. Elliott Miller,Jose Nativi-Nicolau,L. Kristin Newby,Jeong Gun Park,Nicholas Phreaner,Robert O. Roswell,Steven P. Schulman,Shashank S. Sinha,R. Jeffrey Snell,Michael A. Solomon,Jeffrey J. Teuteberg,Wayne Tymchak,Sean van Diepen,David A. Morrow +40 more
TL;DR: There is wide variation in the use of temporary MCS among patients with shock in tertiary CICUs in North America, and hospital-level variation appears to be related, at least in part, to illness severity.
Journal ArticleDOI
Effect of catheter movement and contact during application of radiofrequency energy on ablation lesion characteristics
Matthew D. Olson,Nicholas Phreaner,Joseph L. Schuller,Duy T. Nguyen,David F. Katz,Ryan G. Aleong,Wendy S. Tzou,Raphael Sung,Paul D. Varosy,William H. Sauer +9 more
TL;DR: In this ex vivo model, externally irrigated radiofrequency catheters produced drag lesion volumes equal to or larger than those created by a point-by-point method and decreased lesion size due to intermittent contact can be overcome by increasing duration of ablation time.
Journal ArticleDOI
The Range of Cardiogenic Shock Survival by Clinical Stage: Data From the Critical Care Cardiology Trials Network Registry.
Patrick R. Lawler,David D. Berg,Jeong-Gun Park,Jason N. Katz,Vivian M Baird-Zars,Gregory W. Barsness,Erin A. Bohula,Anthony P. Carnicelli,Sunit-Preet Chaudhry,Jacob C. Jentzer,Venu Menon,Thomas S. Metkus,Jose Nativi-Nicolau,Nicholas Phreaner,Shashank S. Sinha,Jeffrey J. Teuteberg,Sean van Diepen,David A. Morrow +17 more
TL;DR: In this article, a pragmatic application of the Society for Cardiovascular Angiography and Interventions cardiogenic shock staging criteria-A (at-risk), B (beginning), C (classic, deteriorating), or E (extremis)-was developed.
