Objective: This study was aimed to elucidate the feasibility of using right ventricular (RV) strain and strain rate to evaluate right heart function of Ebstein anomaly (EA) patients before and after operation. Methods: Sixty EA patients and 30 healthy controls underwent echocardiography (UCG) for evaluation of right heart function. Preoperative UCG and 1-week and 3-month postoperative UCG were performed in EA patients. RV strain and strain rate were measured on the four-chamber section of tissue Doppler imaging (TDI). Results: The strain and strain rate representative of right ventricle systolic function were reduced prior to operation. RV strain and strain rate improved after the operation (P < .001), most significantly in the basal segment and middle segment of the free wall of the right ventricle as well as the basal segment of the interventricular septum (P < .001). Conclusions: The measurement of RV strain and strain rate on tissue Doppler imaging can be employed to assess the preoperative and postoperative RV function, proves the positive effect of tricuspid valve repair on right heart function, and offers more insight on right heart function evaluation.

Cirrhotic Patients

Introduction: Despite the normal systolic function at rest, cirrhotic patients often suffer from volume overload and symptoms of heart failure as they face stressful situations. This study investigated the myocardial reserve in cirrhotic patients at resting condition and peak stress by dobutamine speckle tracking echocardiography (STE) and tissue Doppler imaging (TDI). Methods: Twenty cirrhotic patients and 10 normal individuals aged 30-50 were selected randomly. For all of the participants, complete echocardiographic study of 2D, STE and TDI was done at rest and peak stress status with dobutamine. The following parameters were assessed: ejection fraction (EF), global longitudinal LV strain (GLS), strain rate in the septal basal segment and lateral wall and E’ in the septal basal segment by color-coded method. Results: At baseline, EF was higher than 55% in both groups. GLS was higher (-22.6±2.4%) in the case group than the control group (-19.2±1.9%) at resting condition. After stress, it showed a greater increase (-22.5±1.7%) in the controls compared to cirrhotic patients (-22.6±3.3%; mean difference = 2.6 ± 2.03, P = 0.02). In cirrhotic patients, the average strain rate in the basal septal segment decreased after stress (-1.2 ± 0.3/s to-1.1 ± 0.3/s), but it increased in the control group (-1.1 ± 0.2/s to -1.8 ± 0.2/s). Conclusion: Despite the presence of normal resting systolic function in cirrhotic patients, there was insufficient increase or even a decrease in myocardial function with stress; this may indicate the absence of sufficient myocardial reserve in cirrhotic patients. These findings would help to explain the reason for occurrence of heart failure or hemodynamic changes in cirrhotic patients.

We investigated the utility of strain, strain rate, and tissue Doppler imaging (TDI) for the evaluation of the right ventricle (RV) impairment in patients with a hypertrophic obstructive cardiomyopathy (HOCM) who underwent a successful alcohol septal ablation (ASA) and were without RV hypertrophy. A group of 19 patients suffering from HOCM with 22 controls was compared. The parameters of TDI were evaluated in mitral and tricuspid annulus. Strain and strain rate derived from TDI were assessed in an apical free wall of RV, as well as in basal segments of the left ventricle. Between both groups, there were significant differences only in isovolumic pre-ejection time (79.2±17.3 ms vs. 58.5±8.1 ms, p<0.01), isovolumic relaxation time (104.7±26.2 ms vs. 77.3±24.5 ms, p<0.01), myocardial performance (Tei) index measured from TDI (0.61±0.14 vs. 0.49±0.09, p<0.01), and early peak diastolic velocity of TDI (10.6±1.67 cm/s vs. 12.6±2.21 cm/s; p<0.05). Our results suggest the impairment of both systolic and diastolic RV function in patients suffering from HOCM. TDI-related parameters appear to be more sensitive than strain and strain rate for evaluation.
