Autor: Igor Klem, Einar Heiberg, Lowie Van Assche, Michele A. Parker, Han W. Kim, John D. Grizzard, Håkan Arheden, Raymond J. Kim

Publikováno v: Journal of Cardiovascular Magnetic Resonance, Vol 19, Iss 1, Pp 1-11 (2017)

Abstract Background Acute myocardial infarct (AMI) size depicted by late gadolinium enhancement cardiovascular magnetic resonance (CMR) is increasingly used as an efficacy endpoint in randomized trials comparing AMI therapies. Infarct size is quantif

Impact of Assuming a Circular Orifice on Flow Error Through Elliptical Regurgitant Orifices: Computational Fluid Dynamics and in Vitro Analysis of Proximal Flow Convergence

Autor: Jeesoo Lee, Sumeet S. Mitter, Lowie Van Assche, Hyungkyu Huh, Gregory J. Wagner, Erik Wu, Alex J. Barker, Michael Markl, James D. Thomas

PurposeGrounded in hydrodynamic theory, proximal isovelocity surface area (PISA) is a simplistic and practical technique widely used to quantify valvular regurgitation flow. PISA provides a relatively reasonable, though slightly underestimated flow r

Background: Microvascular obstruction (MO) is a pathophysiologic complication of acute myocardial infarction that portends poor prognosis; however, it is transient and disappears with infarct healing. Much remains unknown regarding its pathophysiolog

Abstract P413: Latent Class Trajectory Modeling Identifies Distinct Clinical Phenotypes in a Cohort of Patients With Elevated Troponin Levels

Autor: Lucia C. Petito, Anna Pawlowski, Donald M. Lloyd-Jones, Matthew J. Feinstein, Daniel Schneider, Lowie Van Assche, Michael C. Wang

Publikováno v: Circulation. 141

Introduction: Clinicians widely use cardiac troponins I and T, sensitive and specific biomarkers of myocardial damage, as diagnostic criteria for myocardial infarction (MI). A common approach, dichotomizing based on whether troponin levels meet thres

Identifying the Infarct-Related Artery in Patients With Non-ST-Segment-Elevation Myocardial Infarction

Autor: John F, Heitner, Annamalai, Senthilkumar, J Kevin, Harrison, Igor, Klem, Michael H, Sketch, Alexandr, Ivanov, Carine, Hamo, Lowie, Van Assche, James, White, Jeffrey, Washam, Manesh R, Patel, Sebastiaan C A M, Bekkers, Martijn W, Smulders, Terrence J, Sacchi, Raymond J, Kim

Publikováno v: Circulation. Cardiovascular interventions. 12(5)

Determining the infarct-related artery (IRA) in non-ST-segment-elevation myocardial infarction (MI) can be challenging. Delayed-enhancement cardiac magnetic resonance (DE-CMR) can accurately identify small MIs. The purpose of this study was to determ

Functional Mitral Regurgitation: An Interventional Cardiologist's Perspective

Autor: Mark J. Ricciardi, Lowie Van Assche

Publikováno v: Cardiology in review. 26(5)

Functional mitral regurgitation (FMR) is common in patients with heart failure and portends a poor prognosis. The etiology is secondary to nonischemic or ischemic (postmyocardial infarction) adverse remodeling. Treatment includes guideline-directed m

Rationale: After acute myocardial infarction (MI), delineating the area-at-risk (AAR) is crucial for measuring how much, if any, ischemic myocardium has been salvaged. T2-weighted MRI is pro

Autor: Patrick D. Wolf, Han W. Kim, Brett Byram, Lowie Van Assche, Gregg E. Trahey

Publikováno v: Ultrasound in Medicine & Biology. 40:1104-1117

The most common mechanical measure of the heart integrates ventricular strain between end-diastole and end-systole in order to provide a measure of contraction. Here an approach is described for estimating a correlate to local passive mechanical prop
