Autor: Michal Schäfer, PhD, Adam Carroll, MD, Kody K. Carmody, MS, Kendall S. Hunter, PhD, Alex J. Barker, PhD, Muhammad Aftab, MD, T. Brett Reece, MD

Publikováno v: JTCVS Open, Vol 14, Iss , Pp 26-35 (2023)

Objective: The frozen elephant trunk procedure is a well-established technique for the repair of type A ascending aortic dissection and complex aortic arch pathology. The ultimate shape created by the repair may have consequences in long-term complic

Coupled waveform patterns in the arterial and venous fontan circulation are related to parameters of pulmonary, lymphatic and cardiac function

Autor: Margaret R. Ferrari, Michal Schäfer, Kendall S. Hunter, Michael V. Di Maria

Publikováno v: International Journal of Cardiology Congenital Heart Disease, Vol 11, Iss , Pp 100429- (2023)

The lack of a sub-pulmonary ventricle in patients with a Fontan circulation contributes to circulatory decline, largely related to increased central venous pressure. Our group has determined that single-site waveform analysis correlates with clinical

Autor: Melanie J. Dufva, Mario Boehm, Kenzo Ichimura, Uyen Truong, Xulei Qin, Jennifer Tabakh, Kendall S. Hunter, Dunbar Ivy, Edda Spiekerkoetter, Vitaly O. Kheyfets

Publikováno v: Journal of Cardiovascular Magnetic Resonance, Vol 23, Iss 1, Pp 1-14 (2021)

Abstract Background The role of interventricular mechanics in pediatric pulmonary arterial hypertension (PAH) and its relation to right ventricular (RV) dysfunction has been largely overlooked. Here, we characterize the impact of maintained pressure

Functional and molecular determinants of right ventricular response to severe pulmonary hypertension in a large animal model

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 324:H804-H820

Using a large animal model and employing a comprehensive approach integrating hemodynamic, transcriptomic, proteomic, and immunohistochemical analyses, we examined the early (2 wk) effects of severe PH on the RV. We observed that RV remodeling during

Short‐Term Effects of Inhaled Nitric Oxide on Right Ventricular Flow Hemodynamics by 4‐Dimensional–Flow Magnetic Resonance Imaging in Children With Pulmonary Arterial Hypertension

Publikováno v: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, Vol 10, Iss 8 (2021)

Background Pulmonary arterial hypertension (PAH) manifests with progressive right ventricular (RV) dysfunction, which eventually impairs the left ventricular function. We hypothesized that 4‐dimensional–flow magnetic resonance imaging can detect

Publikováno v: Hypertension. 80:482-491

Background: The presence of vascular dysfunction is a well-recognized feature in youth with type 1 diabetes (T1D), accentuating their lifetime risk of cardiovascular events. Therapeutic strategies to mitigate vascular dysfunction are a high clinical

Right Ventricular Dysfunction During Endurance Exercise as Determined by Pressure-Volume Analysis

Autor: Justin A, Edward, Lukasz P, Cerbin, Daniel W, Groves, Robert A, Quaife, Kendall S, Hunter, Benjamin D, Levine, William K, Cornwell

Publikováno v: JACC: Case Reports. 4:1435-1438

A 37-year-old athlete completed invasive endurance (90 km) bicycle exercise testing for right ventricular pressure-volume analysis. Increased right ventricular afterload caused declines in ventricular-arterial coupling and cardiac output, causing inc

Publikováno v: Journal of the American College of Cardiology. 78:1782-1795

Background The effects of nonphysiological flow generated by continuous-flow (CF) left ventricular assist devices (LVADs) on the aorta remain poorly understood. Objectives The authors sought to quantify indexes of fibrosis and determine the molecular

Publikováno v: Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, Vol 6, Iss 12 (2017)

BackgroundQualitative and quantitative flow hemodynamic indexes have been shown to reflect right ventricular (RV) afterload and function in pulmonary hypertension (PH). We aimed to quantify flow hemodynamic formations in pulmonary arteries using 4‐
