“…16 Jategaonkar et al showed that RV volume overload was associated with increased S values, which returned to normal after abolishment of the volume overload, whereas SR was found to be less preloaddependent. 17 Their findings represent chronic preload changes in the RV as patients were examined before and 3 months after ASD closure. To our knowledge, ours is the first human study to examine the effect of acute preload reduction on 2DST parameters of the systemic RV.…”

“…There have been conflicting results regarding the load sensitivity of the strain and SR of the RV when measured by Doppler 16 and speckle tracking studies. 17 The objectives of this study were to assess the effect of acute preload reduction and increased inotropy on 2D longitudinal strain and SR in patients with HLHS and relate these parameters to simultaneously derived load-independent measures of ventricular function measured by conductance catheter technique.…”

Background— Assessment of systemic right ventricular (RV) function in patients with hypoplastic left heart syndrome is important during long-term follow-up after Fontan repair. Traditional echocardiographic parameters to evaluate systolic ventricular function are affected by loading conditions. The only generally accepted load-independent parameter of systolic function, end systolic elastance ( E es ), requires invasive catheterization. Therefore, we sought to determine if parameters obtained by 2-dimensional speckle tracking (2DST) were affected by acute changes in preload and correlated with catheterization-derived indices of RV contractility in hypoplastic left heart syndrome patients after Fontan palliation. Methods and Results— Fifty-two patients with hypoplastic left heart syndrome (median age, 6.6; range 2.9–22.2 years) were prospectively enrolled to have echocardiography and conductance catheter studies performed simultaneously. We compared traditional echo, 2-dimensional speckle tracking and catheterization-derived parameters during different states of preload at baseline and during dobutamine infusion. Global longitudinal strain (S) showed a tendency to decrease with preload reduction, whereas global longitudinal strain rate (SR) did not change (S: −17.7±3.4% versus −16.9±3.8%, P =0.08; SR: −1.30±0.29 versus −1.34±0.34 s −1 , P =0.3). S did not change with dobutamine infusion (−17.7±3.4% versus −18.4±3.9%, P =0.24), whereas SR increased significantly (−1.30±0.29 versus −2.26±0.49 s −1 , P <0.001). RV E es correlated with SR ( r s = −0.47, P <0.001), but not with S ( r s =0.07, P =0.5) or other echocardiographic parameters. Conclusions— In contrast to S, SR was not affected by preload and correlated with E es of the systemic RV. SR may be a useful noninvasive surrogate of RV contractility and suitable for follow-up of patients with hypoplastic left heart syndrome after Fontan palliation.

Two-dimensional strain (2DS) is a novel method to measure strain from standard two-dimensional echocardiographic images by speckle tracking, which is less angle dependent and more reproducible than conventional Doppler-derived strain. The objective of our study was to characterize global and regional function abnormalities using 2DS and strain rate analysis in patients (pts) with pathological left ventricular hypertrophy (LVH) caused by non-obstructive hypertrophic cardiomyopathy (HCM), in top level athletes, and in healthy controls. The hypothetical question was, if 2DS might be useful as additional tool in differentiating between pathologic and physiologic hypertrophy in top-level athletes. We consecutively studied 53 subjects, 15 pts with hypertrophic cardiomyopathy (HCM), 20 competitive top-level athletes, and a control group of 18 sedentary normal subjects by standard echocardiography according to ASE guidelines. Global longitudinal strain (GLS) and regional peak systolic strain (PSS) was assessed by 2DS in the apical four-chamber-view using a dedicated software. All components of strain were significantly reduced in pts with HCM (GLS: -8.1 ± 3.8%; P < 0.001) when compared with athletes (-15.2 ± 3.6%) and control subjects (-16.0 ± 2.8%). In general, there was no significant difference between the strain values of the athletes and the control group, but in some of the segments, the strain values of the control group were significantly higher than those in the athletes. A cut-off value of GLS less than -10% for the diagnosis of pathologic hypertrophy (HCM) resulted in a sensitivity of 80.0% and a specificity of 95.0%. The combination of TDI (averaged S', E') and 2DS (GLS) cut-off values for the detection of pathologic LVH in HCM demonstrated a sensitivity of 100%, and a specificity of 95%. Two-dimensional strain is a new simple and rapid method to measure GLS and PSS as components of systolic strain. This technique could offer a unique approach to quantify global as well as regional systolic dysfunction, and might be used as new additional tool for the differentiation between physiologic and pathologic LVH.
