“…Valores de strain e strain rate são então obtidos no próprio equipamento ou em uma estação de computador a partir de algoritmos específicos, colocando-se o volume da amostra ou regiões de interesse de tamanhos distintos na porção média do segmento a ser estudado. Valores de strain e strain rate foram estudados em diversas situações em que há acometimento do VD, incluindo displasia arritmogênica do VD 131 , embolia pulmonar, 132 hipertensão pulmonar, 133 ventrículo direito sistêmico, 134 e amiloidose. [135][136][137] Existem poucos dados na literatura sobre valores de strain e strain rate para a população normal.…”

“…The images were further analyzed using the 2-dimensional strain software (EchoPAC, General Electric/Vingmed Ultrasound, Horten, Norway) with calculation of RV global longitudinal systolic strain, systolic strain rate, and early and late diastolic strain rates for the entire traced contour of the right ventricle. 16,17 Pulsed-wave Doppler assessment was performed to detect restrictive right ventricular physiology as defined by the presence of late-diastolic antegrade flow in the pulmonary artery throughout the respiratory cycle. 15 Color tissue Doppler imaging data were recorded from the apical 4-chamber view with determination of the peak tricuspid annular systolic (s), early diastolic (e), and late diastolic (a) velocities and RV isovolumic acceleration (IVA) during myocardial contraction.…”

Background: The hypertrophic myocardium, myocardial fiber disarray, and endocardial fibroelastosis in pulmonary atresia and intact ventricular septum (PAIVS) may provide anatomic substrates for restrictive filling of the right ventricle. Hypothesis: Restrictive right ventricle (RV) physiology is related to RV fibrosis and exercise capacity in patients after biventricular repair of PAIVS. Methods: A total of 27 patients, age 16.5 ± 5.6 years, were recruited after biventricular repair of PAIVS. Restrictive RV physiology was defined by the presence of antegrade diastolic pulmonary flow and RV fibrosis assessedby late gadolinium enhancement (LGE) cardiac magnetic resonance.Their RV function was compared with that of 27 healthy controls and related to RV LGE score and exercise capacity. Results: Compared with controls, PAIVS patients had lower tricuspid annular systolic and early diastolic velocities, RV global longitudinal systolic strain, systolic strain rate, and early and late diastolic strain rates (all P < 0.05). A total of 22 (81%, 95% confidence interval: 62%-94%) PAIVS patients demonstrated restrictive RV physiology. Compared to those without restrictive RV physiology (n=5), these 22 patients had lower RV global systolic strain, lower RV systolic and early diastolic strain rates, higher RV LGE score, and a greater percent of predicted maximum oxygen consumption (all P < 0.05). Conclusion: Restrictive RV physiology reflects RV diastolic dysfunction and is associated with more severe RV fibrosis but better exercise capacity in patients after biventricular repair of PAIVS. IntroductionThe evolution in management strategy has significantly improved the long-term outcomes of patients with pulmonary atresia and intact ventricular septum (PAIVS). 1 -3 In the presence of a reasonably good-sized right ventricle and the absence of a right ventricular (RV)-dependent coronary circulation, RV decompression could be achieved by outflow reconstruction, 2 -5 surgical pulmonary valvotomy,

“…Nowadays, TDI and strain and SRI are used to assess right ventricular function (10,17). Since SRI shows clearer quantitative values and more objective parameters, especially when clinical status shows intangible results, it could indicate a more precise examination of right ventricle (18). Hence, in the present study to investigate the postoperative right ventricular function we used the strain and SRI, in addition to TAPS and TDI.…”

Background: Right ventricle function significantly decreases after coronary artery bypass surgery; as one of the likely causes, such a condition is attributed to the use of cardiopulmonary pump (CPB). Because nowadays there is a tendency toward increasing use of off-pump coronary artery bypass (OPCAB) surgery, this study was conducted to evaluate the right ventricle function after this type of surgery using strain and strain rate imaging (SRI) echocardiography.Methods: This study was conducted on 30 patients, candidate for elective OPCAB surgery, between 2011 and 2012. Standard echocardiography was performed before the surgery and the right ventricle function was examined using strain and SRI echocardiography. Then patient underwent surgery, 6 days and 3 months after surgery they underwent echocardiography again and the results obtained from the three stages were compared with each other.Results: Participants included 30 patients (23 males and 7 females) with a mean age of 66±11 years.Compared to the prior of the surgery, 6 days and 3 months after the surgery there was a significant decrease in tricuspid annular plane systolic excursion (TAPSE), tissue Doppler imaging (TDI) at the lateral annulus of tricuspid valve, and strain and SRI of right ventricle. However, the values obtained 3 months after surgery were significantly higher than those obtained after 6 days. In other words, the right ventricle function 6 days after the surgery had dropped, however some of the values recovered 3 months after the surgery. Conclusions:The findings of this study are consistent with other studies in this field and showed that after coronary artery surgery a decline occurs in right ventricular function. However, more detailed quantitative strain and SRI parameters which were measured in our study showed that at the early days after the OPCAB surgery there is a decline in the right ventricle function which is relatively reversible at longer intervals (3 months after surgery).Keywords: Right ventricle function; off-pump coronary artery bypass surgery (OPCAB surgery); off-pump coronary artery bypass surgery (OPCAB); strain and strain rate imaging echocardiography (strain and SRI echocardiography)
