Murine Echocardiography

Doppler-echocardiographic assessment of cardiovascular structure and function in murine models has developed into one of the most commonly used non-invasive techniques during the last decades. Recent technical improvements even expanded the possibilities. In this review, we summarize the current options to assess global left ventricular (LV) function in mice using echocardiographic techniques. In detail, standard techniques as structural and functional assessment of the cardiovascular phenotype using one-dimensional M-mode echocardiography, two-dimensional B-mode echocardiography and spectral Doppler signals from mitral inflow respective aortal outflow are presented. Further pros and contras of recently implemented techniques as three-dimensional echocardiography and strain and strain rate measurements are discussed. Deduced measures of LV function as the myocardial performance index according to Tei, estimation of the mean velocity of circumferential fibre shortening, LV wall stress and different algorithms to estimate the LV mass are described in detail. Last but not least, specific features and limitations of murine echocardiography are presented. Future perspectives in respect to new examination techniques like targeted molecular imaging with advanced ultrasound contrast bubbles or improvement of equipment like new generation matrix transducers for murine echocardiography are discussed.

Abstract Background Three-dimensional saddle-shaped annuloplasty rings have been shown to create a larger surface of leaflet coaptation in mitral valve repair (MVR) for functional mitral regurgitation (FMR) and degenerative mitral regurgitation (DMR) which may increase repair durability. For the first time, this study reports mid-term results after MVR for DMR and FMR using a rigid three-dimensional ring (Profile 3D, Medtronic). Methods Between June 2009 and June 2012, 369 patients with DMR (n = 326) or FMR (n = 43) underwent MVR (mean age 62.3 ± 12.6 years). A total of 205 patients (55.6%) underwent isolated MVR and 164 patients (44.4%) a combined procedure. Follow-up examinations were performed in 94.9% (mean 4.9 ± 0.9 years). Echocardiographic assessment was complete in 93.2% (mean 4.3 ± 1.2 years). Results The 30-day mortality was 1.5% (5/326) for DMR (1.5% for isolated and 1.6% for combined procedures) and 9.3% (4/43) for FMR (0% for isolated and 10.5% for combined procedures). Survival at 6 years was 92.1 ± 1.9% for DMR (92.9 ± 2.6% for isolated and 90.7 ± 2.7% for combined procedures) and 66.4 ± 7.9% for FMR (80.0 ± 17.9% for isolated and 63.7 ± 8.9% for combined procedures). Cumulative risk for mitral valve-related reoperation at 6 years was 0% for FMR and 7.1 ± 1.5% for DMR. At echocardiographic follow-up, one patient presented with mitral regurgitation (MR) more than moderate. The only predictor of recurrent MR after MVR for DMR was residual mild MR at discharge. Conclusion Repair of FMR with the three-dimensional Profile 3D annuloplasty ring shows excellent mid-term results with regard to recurrence of MR. In cases of DMR, the results are conforming to the current literature.

Abstract Aims Right ventricular (RV) function assessment is crucial in congenital heart disease patients, especially in atrial septal defect (ASD) and repaired Tetralogy of Fallot (TOF) patients with pulmonary regurgitation (PR). In this study, we aimed to analyse both 3D RV shape and deformation to better characterize RV function in ASD and TOF-PR. Methods and results We prospectively included 110 patients (≥16 years old) into this case–control study: 27 ASD patients, 28 with TOF, and 55 sex- and age-matched healthy controls. Endocardial tracking was performed on 3D transthoracic RV echocardiographic sequences and output RV meshes were post-processed to extract local curvature and deformation. Differences in shape and deformation patterns between subgroups were quantified both globally and locally. Curvature highlights differences in RV shape between controls and patients while ASD and TOF-PR patients are similar. Conversely, strain highlights differences between controls and TOF-PR patients while ASD and controls are similar [global area strain: −31.5 ± 5.8% (controls), −34.1 ± 7.9% (ASD), −24.8 ± 5.7% (TOF-PR), P < 0.001, similar significance for longitudinal and circumferential strains]. The regional and local analysis highlighted differences in particular in the RV free wall and the apical septum. Conclusion Chronic RV volume loading results in similar RV shape remodelling in both ASD and TOF patients while strain analysis demonstrated that RV strain is only reduced in the TOF group. This suggests a fundamentally different RV remodelling process between both conditions.

Abstract Background Chronic restrictive pulmonary disease may alter right and left ventricular function by changing intrathoracic pressure. Pulmonary hyperinflation may increase right atrial pressure, leading to reduced venous return and subsequent reductions in RV pre-load. In CRPD patients, hyperinflation has been directly correlated with reduced atrial chamber size, global RV dysfunction, and reduced LV filling. Accurate assessment of global and regional right ventricular (RV) systolic function is challenging. Purpose The aims of this study were to confirm the reliability and feasibility of a three-dimensional (3D) speckle-tracking echocardiography (STE) system, using comparison with cardiac magnetic resonance imaging (CMR), and to assess the contribution of regional RV function to global function. Methods In a retrospective, cross-sectional study setting, RV volumetric data were studied in 200 patients who were referred for both CMR and 3D echocardiography within 1 month. Three-dimensional STE-derived area strain, longitudinal strain, and circumferential strain were assessed as global, inlet, outflow, apical, and septal segments. Results 136 patients (68%) had adequate 3D echocardiographic data. RV measurements derived from 3D STE and CMR were closely related (RV end-diastolic volume, R2=0.89; RV end-systolic volume, R2=0.82; RV ejection fraction [RVEF], R2=0.68; P<0.003 for all). RVEF and RV end-diastolic volume from 3D STE were slightly but significantly smaller than CMR values (mean differences, −3% and −8 mL for RVEF and RV end-diastolic volume, respectively). Among conventional echocardiographic parameters for RV function (tricuspid annular plane systolic excursion, fractional area change, S' of the tricuspid annulus, RV free wall two-dimensional longitudinal strain), only fractional area change was significantly related to RVEF (r=0.30, P=0.005). Among segmental 3D strain variables, inlet area strain (r=−0.49, P<0.004) and outflow circumferential strain (r=−0.39, P<0.005) were independent factors associated with CMR-derived RVEF. Conclusions Severity of restrictive pulmonary disease influences RV systolic dysfunction, which is reflected in speckle tracking 3D echocardiographic parameters. Regional RV wall motion showed that heterogeneous segmental deformations affect global RV function differently; specifically, inlet area strain and outflow circumferential strain.RV volume and RVEF determined by STE were comparable with CMR measurements.

Abstract Purpose The purpose of this study was to examine right ventricular (RV) function by three-dimensional speckle-tracking echocardiography (3DSTE) in patients after correction of tetralogy of Fallot (TF), the accuracy of 3DSTE compared to cardiovascular magnetic resonance (CMR) findings and assess pulmonary arterial (PA) distensibility in order to achieve a more comprehensive understanding of the matching between RV performance and PA load. Methods Twenty-one patients (mean age 39 ± 16 years) with repaired TF and twenty-one age-matched healthy subjects selected as controls were studied. CMR findings were available in 14 patients. RV volumes, RV ejection fraction (RVEF) and RV longitudinal and circumferential strains were calculated by three-dimensional echocardiography and three-dimensional speckle tracking echocardiography. The main pulmonary artery was interrogated by color, pulsed, and continuous-wave Doppler. Pulmonary regurgitation (PR) was assessed by color-flow mapping and graded as none, mild, or greater than mild using the measurement of the regurgitant jet width in relation to the outflow tract diameter. Right pulmonary artery (PA) was visualized from suprasternal view by two-dimensional echocardiography. Tissue Doppler Imaging (TDI) mode was activated in B-mode imaging to examine arterial motion, then mode was changed to color-mode with the beam line aligned perpendicular to the superior and inferior walls of the right PA. PA distensibility and strain were determined. Data analysis was performed offline. Results Overall, 3D RVEF and RV longitudinal strain were reduced in TF patients compared to the control group. Nine patients had moderate or moderate-to-severe PR. PA strain and distensibility were decreased (p = 0.003) compared with controls, both in the presence and absence of PR. PA strain had a positive correlation with RVEF (r = 0.79, p &lt; 0.005) and RV strain (r = 0.82, p &lt; 0.001). RV end-diastolic and end-systolic volumes by 3DE correlated with the respective parameters by CMR (r = 0.88,p &lt; 0.001 and r = 0.87,p &lt; 0.005 respectively). Patients with moderate-to-severe PR had more prominent PA strain changes (p = 0.02). Conclusions Three-dimensional right ventricular ejection fraction and RV strain are impaired in patients with repaired TF, in agreement with CMR data. Reduced PA strain is associated with reduced RV 3DSTE parameters and is more pronounced in the presence of pulmonary regurgitation.
