“…Here, we measured the total strain during ejection phase, given by ln(SA ES /SA ED ), so that SA 0 can be omitted. The 3-D area strain may provide more accurate endocardial information because 3-D area strain coupled with both 3-D longitudinal and circumferential directions is considered to be most sensitive to changes in myocardial function (26,31).…”

“…Conventional strain analysis (i.e., radial, circumferential, and longitudinal strain) has been limited by two-dimensional (2-D) MRI and echocardiography. Area strain (AS) based on 3-D approach has been recently introduced for the LV (31). Basically, area strain reflects deformation of the endocardial surface during contraction and relaxation and can be regarded as a parameter that integrates the regional consequence of deformation in longitudinal, circumferential, and radial directions.…”

Tan RS, Kassab G. Right ventricular regional wall curvedness and area strain in patients with repaired tetralogy of Fallot. Am J Physiol Heart Circ Physiol 302: H1306 -H1316, 2012. First published December 30, 2011 doi:10.1152/ajpheart.00679.2011.-A quantitative understanding of right ventricular (RV) remodeling in repaired tetralogy of Fallot (rTOF) is crucial for patient management. The objective of this study is to quantify the regional curvatures and area strain based on three-dimensional (3-D) reconstructions of the RV using cardiac magnetic resonance imaging (MRI). Fourteen (14) rTOF patients and nine (9) normal subjects underwent cardiac MRI scan. 3-D RV endocardial surface models were reconstructed from manually delineated contours and correspondence between end-diastole (ED) and end systole (ES) was determined. Regional curvedness (C) and surface area at ED and ES were calculated as well as the area strain. The RV shape and deformation in rTOF patients differed from normal subjects in several respects. Firstly, the curvedness at ED (mean for 13 segments, 0.030 Ϯ 0.0076 vs. 0.029 Ϯ 0.0065 mm Ϫ1 ; P Ͻ 0.05) and ES (mean for 13 segments, 0.040 Ϯ 0.012 vs. 0.034 Ϯ 0.0072 mm Ϫ1 ; P Ͻ 0.001) was decreased by chronic pulmonary regurgitation. Secondly, the surface area increased significantly at ED (mean for 13 segments, 982 Ϯ 192 vs. 1,397 Ϯ 387 mm 2 ; P Ͻ 0.001) and ES (mean for 13 segments, 576 Ϯ 130 vs. 1,012 Ϯ 302 mm 2 ; P Ͻ 0.001). In particular, rTOF patients had significantly larger surface area than that in normal subjects in the free wall but not for the septal wall. Thirdly, area strain was significantly decreased (mean for 13 segments, 56 Ϯ 6 vs. 34 Ϯ 7%; P Ͻ 0.0001) in rTOF patients. Fourthly, there were increases in surface area at ED (5,726 Ϯ 969 vs. 6,605 Ϯ 1,122 mm 2 ; P Ͻ 0.05) and ES (4,280 Ϯ 758 vs. 5,569 Ϯ 1,112 mm 2 ; P Ͻ 0.01) and decrease in area strain (29 Ϯ 8 vs. 18 Ϯ 8%; P Ͻ 0.001) for RV outflow tract. These findings suggest significant geometric and strain differences between rTOF and normal subjects that may help guide therapeutic treatment. magnetic resonance imaging; curvature; right ventricular remodeling; deformation; three-dimensional reconstruction TETRALOGY OF FALLOT (TOF) is the most common cyanotic congenital heart disease (19). The main features include ventricular septum defect, subpulmonary stenosis, and overriding aorta and right ventricular (RV) hypertrophy. Surgical repair is usually performed in early infancy to widen the passage from the RV to the pulmonary artery and close the ventricular septal defect. This ensures separation of oxygen-rich and oxygenpoor blood flows to the proper chambers. Surgical repair of TOF often involves disruption of pulmonary valve integrity that leads to pulmonary regurgitation (PR; Refs. 8, 37). This in turn causes RV dilation (9, 23) and RV outflow tract (RVOT) aneurysm (2-3, 13, 28 -29). The RV dilation is usually tolerated with little or no symptoms during the first two to three decades of age. If left untreated, however, continued...

“…Via 3D-STI technology, the three-dimensional motion trajectory of each myocardial spot was continuously tracked in the heart. Real-time variable curves of different cardiac tissues for different movement directions were obtained, and when compared with two-dimensional ultrasound speckle tracking imaging technology, left ventricular systolic function was more realistically and accurately reflected (Pérez et al, 2009). …”

ABSTRACT. Three-dimensional ultrasound speckle tracking imaging was used to evaluate the effects of recombinant human brain natriuretic peptide (rhBNP) in acute anterior and extensive anterior myocardial infarction. Ninety patients with acute anterior or extensive myocardial infarction were randomly divided into 3 groups: Group A [emergency percutaneous coronary intervention (PCI)], Group B (emergency PCI + rhBNP early treatment), and Group C (emergency PCI + late rhBNP treatment). Within 6 h of admission and at 1 week and 3 and 6 months after PCI, patients underwent routine transthoracic echocardiography and real-time three-dimensional echocardiography. At 1 week, 1 month, 3 months, 6 months, and 12 months, ejection fraction values in groups B and C were significantly greater than those in group A (P < 0.05), and Y. Zhang et al. 5700©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (2): 5699-5709 (2015) left ventricular end-diastolic volume and left ventricular end-systolic volume values in groups B and C were less than those in group A (P < 0.05). Within 6 h of admission in each group, long-axis, radial, circumferential, and area variables corresponding to anterior descending artery segments showed no significant difference (all P > 0.05). However, at 1 week, 1 month, 3 months, 6 months, and 12 months, long-axis, radial, circumferential and area variables in groups B and C were significantly less than those in group A (P < 0.05). Intervention with rhBNP can improve resilience of the local myocardium, left ventricular mechanical function, and cardiac remodeling. Within 6 h of admission or after PCI, rhBNP application showed no significant difference in heart function improvement or myocardial remodeling inhibition.
