Background: We tested the hypothesis that speckle-tracking strain imaging can quantify longitudinal right ventricular (RV) function and its association with left ventricular (LV) function in patients with myocardial infarction (MI). Methods: To quantify longitudinal RV function, 39 patients with old MI (OMI: LV ejection fraction 17 – 77 %, 45 ±16 %) and 29 age matched normal controls (Control: LV ejection fraction 65 ± 5 %) were studied with echocardiography. Longitudinal RV global peak systolic strain was assessed from apical four-chamber view using speckle-tracking imaging (EchoPAC, GE Electronic). RV fractional area change was also analyzed. Results: Longitudinal RV global peak systolic strain was significantly impaired in OMI compared to Control (−18 ± 5* and −25 ± 4 %, *p < 0.05 vs. Control) whereas RV fractional area change failed to discriminate from normal to impaired RV function (OMI: 48 ± 11 vs. Control: 52 ± 6 %, p = NS). When divided OMI into three groups regarding to plasma BNP level (Group A: BNP < 100 pg/ml; n = 14, Group B: 100 pg/ml ≤ BNP < 500 pg/ml; n = 14, and Group C; BNP ≥ 500 pg/ml; n = 11), Group A had no significant relations between longitudinal RV global peak systolic strain and LV ejection fraction (y = −0.07x − 11, r = 0.30, p = NS) whereas those were significantly correlated in Group B (y = −0.18x − 11, r = 0.59*, *p < 0.05). Furthermore, the strongest correlation between longitudinal RV global peak systolic strain and LV ejection fraction was observed in Group C (y = −0.58x + 5, r = 0.90*, *p < 0.05). Conclusion: Speckle tracking strain imaging quantified longitudinal RV global systolic function and exhibited its BNP-related dependency to LV systolic function in patents with OMI.

Abstract Background Right ventricular (RV) dysfunction played a decisive role in clinical management and associated with poor prognosis in acute pulmonary embolism (PE). It still remains challenging to estimate RV function accurately for the reason of complex structure and geometry. The present study aimed to determine the value of right ventricular outflow tract systolic excursion (RVOT-SE) in evaluating RV function in an animal model with acute PE. Methods Thirty-three healthy New Zealand rabbits were randomly assigned to massive thrombus group, sub-massive thrombus group and control group, 11 rabbits per group. The acute PE model was established by intravenous infusion of autologous blood clots. After 1h of thrombus injection, transthoracic echocardiography was performed to assess RV function in all rabbits. Results The acute PE model was successfully made in 18 rabbits (massive thrombus group, n = 8; sub-massive thrombus group n = 10). Right/left ventricular end-diastolic diameter (RV/LV) ratio and RV myocardial performance (Tei) index were significantly increased, while RV fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE) and RVOT_SE were reduced in massive thrombus group. The value of RVOT-SE and RVFAC in sub-massive thrombus group decreased significantly compared with control group (P < 0.05). But there was no significant difference in RV/LV, TAPSE and Tei index (P > 0.05). ROC analysis showed that RVOT-SE had high sensitivity (94.4%) and specificity (72.7%) in identifying RV dysfunction in acute PE. The area under the ROC curve (AUC) for combined TAPSE and RVOT-SE was greater than that of TAPSE or RVOT-SE alone (AUC= 0.962, P < 0.01). Conclusion RV function in acute PE is significantly decreased, which is closely related to the size of embolus. RVOT_SE is a simple and highly distinctive parameter in identifying RV dysfunction and tends to be superior to conventional parameters in acute PE. The combination of RVOT-SE and TAPSE can further improve the diagnostic accuracy of acute PE.

Purpose: Right ventricular (RV) dysfunction in acute pulmonary embolism (PE) is a critical determinant of outcome. Obstructive sleep apnea (OSA) is a common comorbidity of PE and might also affect RV function. Therefore, we sought to investigate RV dysfunction in PE patients in proportion to the severity of OSA by evaluating the right-to-left ventricular (RV/LV) diameter ratio on computed tomographic pulmonary angiography (CTPA). Materials and Methods: 197 PE patients were evaluated for sleep-disordered breathing by portable monitoring and nocturnal polysomnography. RV dilatation was defined as an RV/LV diameter ratio of ⩾ 1.0. Results: RV dilatation was significantly more frequent in OSA patients compared to study participants without OSA (66.4% vs 49.1%, P = .036). Elevated troponin I values, indicating myocardial injury due to acute, PE-related RV strain, were significantly more frequent in OSA patients with an apnea-hypopnea index (AHI) ⩾ 15/h compared to those with an AHI < 15/h (62.1% vs 45.8%, P = .035). However, RV dysfunction documented by the RV/LV diameter ratio on CTPA was not significantly associated with the severity of OSA in multivariable regression analysis. Conclusion: Patients with moderate or severe OSA might compensate acute, PE-related RV strain better, as they are adapted to repetitive right heart pressure overloads during sleep.

Myocardial Deformation Imaging

Myocardial deformation imaging (strain imaging) is a technique to directly quantify the extent of myocardial contractility and overcomes several of the limitations of ejection fraction. The application of the most commonly used strain imaging method; speckle-tracking echocardiography to patients with sepsis cardiomyopathy heralds an exciting development to the field. However; the body of evidence and knowledge on the utility, feasibility and prognostic value of left ventricular global longitudinal strain in sepsis cardiomyopathy is still evolving. We conducted a review of literature on utility of left ventricular global longitudinal strain in sepsis cardiomyopathy. We discuss the role of left ventricular global longitudinal strain in mortality prediction, utility and limitations of the technique in the context of sepsis cardiomyopathy.
