Item Assessment of Myocardial Mechanics in Patients with End-Stage Renal Disease and Renal Transplant Recipients Using Speckle Tracking Echocardiography(2015) Pirat, Bahar; Bozbas, Huseyin; Simsek, Vahide; Sade, L. Elif; Sayin, Burak; Muderrisoglu, Haldun; Haberal, Mehmet; 0000-0002-9635-6313; 0000-0003-4576-8630; 0000-0003-3737-8595; 0000-0002-3462-7632; 0000-0001-8287-6572; 25894162; AAG-8233-2020; AAI-8897-2021; AAQ-7583-2021; AAJ-8097-2021; J-3707-2015Objectives: Velocity vector imaging allows quantitation of myocardial strain and strain rate from 2-dimensional images based on speckle tracking echocardiography. The aim of this study was to analyze the changes in myocardial strain and strain rate patterns in patients with end-stage renal disease and renal transplant recipients. Materials and Methods: We studied 33 patients with end-stage renal disease on hemodialysis (19 men; mean age, 36 +/- 8 y), 24 renal transplant recipients with functional grafts (21 men; mean age, 36 +/- 7 y) and 26 age- and sex-matched control subjects. Longitudinal peak systolic strain and strain rate for basal, mid, and apical segments of the left ventricular wall were determined by velocity vector imaging from apical 4- and 2-chamber views. The average longitudinal strain and strain rate for the left ventricle were noted. From short-axis views at the level of papillary muscles, average circumferential, and radial strain, and strain rate were assessed. Results: Mean heart rate and systolic and diastolic blood pressure during imaging were similar between the groups. Longitudinal peak systolic strain and strain rate at basal and mid-segments of the lateral wall were significantly higher in renal transplant recipients and control groups than end-stage renal disease patients. Average longitudinal systolic strain from the 4-chamber view was highest in control subjects (-14.5% +/- 2.9%) and was higher in renal transplant recipients (-12.5% +/- 3.0%) than end-stage renal disease patients (-10.2% +/- 1.6%; P <= .001). Radial and circumferential strain and strain rate at the level of the papillary muscle were lower in patients with end-stage renal disease than other groups. Conclusions: Differences in myocardial function in patients with end-stage renal disease, renal transplant recipients, and normal controls can be quantified by strain imaging. Myocardial function is improved in renal transplant recipients compared with end-stage renal disease patients.Item COMPARISON OF PURE ANTIBODY-MEDIATED REJECTION (AMR) WITH MIXED CELLULAR AND AMR IN REGARDS TO THE DEVELOPMENT OF CARDIAC ALLOGRAFT VASCULOPATHY (CAV) AND CARDIOVASCULAR MORTALITY (CVM) IN HEART TRANSPLANT PATIENTS(2019) Ozdemir, B.

Elif; Faletra, Francesco F.; Fortuni, Federico; Rossi, Alexia; Soulat-Dufour, Laurie; 35079782The right atrium (RA) is the cardiac chamber that has been least well studied. Due to recent advances in interventional cardiology, the need for greater understanding of the RA anatomy and physiology has garnered significant attention. In this article, we review how a comprehensive assessment of RA dimensions and function using either echocardiography, cardiac computed tomography, and magnetic resonance imaging may be used as a first step towards a better understanding of RA pathophysiology. The recently published normative data on RA size and function will likely shed light on RA atrial remodelling in atrial fibrillation (AF), which is a complex phenomenon that occurs in both atria but has only been studied in depth in the left atrium. Changes in RA structure and function have prognostic implications in pulmonary hypertension (PH), where the increased right ventricular (RV) afterload first induces RV remodelling, predominantly characterized by hypertrophy. As PH progresses, RV dysfunction and dilatation may begin and eventually lead to RV failure. Thereafter, RV overload and increased RV stiffness may lead to a proportional increase in RA pressure. This manuscript provides an in-depth review of RA anatomy, function, and haemodynamics with particular emphasis on the changes in structure and function that occur in AF, tricuspid regurgitation, and PH.Item Left atrial deformations: So clinically relevant(2022) Donal, Erwan; Sade, L.
