Right ventricular transverse displacement increases following cardiac surgery: possibly compensating loss in tricuspid annular plane systolic excursion (TAPSE)

Perioperative Course of Three-Dimensional–Derived Right Ventricular Strain in Coronary Artery Bypass Surgery: A Prospective, Observational, Pilot Trial

“…This was an unexpected finding because the authors had expected 3D-RV EF and RV FAC to change similarly because this had been reported in existing literature. [25][26][27] Tamborini et al 5 observed a decline of the longitudinal 2D parameter of RV function (TAPSE, RV S), whereas 3D-RV EF remained unchanged, measured with TTE before surgery and three months after surgery. This NOTE.…”

“…Altogether, data are conflicting on the perioperative changes of the different parameters of RV function assessment in cardiac surgery, assessed either with perioperative TTE 25,[28][29][30][31] or with intraoperative TEE. [25][26][27][32][33][34][35] Whereas some authors have reported deterioration of 2D-RV FWS postoperatively, 25,28,29,[31][32][33][34][35] others have observed unchanged values. 27,36 The same is true for RV FAC, assessed with perioperative TTE 25,28,30,31 or with intraoperative TEE.…”

The right ventricle after cardiopulmonary bypass: new insights on its adaptive physiology

“…Interestingly, while a constant reduction in longitudinal function from pre to post-bypass to chest closure (measured both as TAPSE, S′ and speckle tracking derived RV longitudinal displacement) was observed, in post-CPB both free wall and septum speckle tracking-derived transversal displacement increased, and contributed to preserving stroke volume (SV). Post chest closure SV reduction was then observed, due to both RV end-diastolic volume reduction, and loss of this "septal compensation" [7,8]. However, as paradoxical septal motion (PSM) is a frequent echocardiographic finding after CPB, we may speculate that all the septal features, observed in the present study, are related to the open chest-pericardium and their closure.…”

“…In the present issue of the Journal of Clinical Monitoring and Computing Korshin et al describe interesting echocardiographic observations which cast further light on the increasingly studied behaviour of the right ventricle (RV) after on-pump cardiac surgery [7]. By speckle tracking analysis of RV regional contraction and motion, the authors elegantly characterized the RV contractility pattern in different phases of uncomplicated CABG surgery, in patients with baseline normal biventricular function.…”

The Limitations of Using Transthoracic Echocardiographic–Derived Normative Values for Grading Intraoperative Transesophageal Echocardiography Examinations of the Right Ventricle: Are They Really Interchangeable?

“…Overall, there is significant variability among studies regarding feasibility and concordance between midesophageal 4-chamber and transgastric windows and between TEE and TTE. [17][18][19] These variabilities likely reflect image acquisition and quality, exposing the angle dependency of these measures.…”
